具体实施方式Detailed ways

下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

显示装置在使用过程中，驱动芯片不断向显示面板中的像素传输用于驱动其显示的驱动信号，因此，如果驱动芯片异常掉电，将导致显示面板内留存着不被需要的电荷，这些电荷若不能得到彻底释放，会对显示面板的性能产生不良影响，因此，驱动芯片需要在异常掉电后，释放显示面板内留存的电荷。留存电荷的释放需要一定的时间(至少1ms)，而传统的备用电源(例如驱动芯片内的备用电容)的存储电量较少，难以保证供应驱动芯片足够的电能，使其将留存电荷彻底释放，因而难以彻底解决驱动芯片异常掉电的不良影响。During the use of the display device, the driver chip continuously transmits the drive signal for driving the display to the pixels in the display panel. Therefore, if the driver chip is powered off abnormally, unnecessary charges will remain in the display panel. If it cannot be completely released, the performance of the display panel will be adversely affected. Therefore, the driver chip needs to release the charge remaining in the display panel after an abnormal power failure. It takes a certain amount of time (at least 1ms) to release the retained charge, and the traditional backup power supply (such as the backup capacitor in the driver chip) has less storage power, and it is difficult to ensure enough power to supply the driver chip to completely release the retained charge. Therefore, it is difficult to completely solve the adverse effect of abnormal power failure of the driver chip.

为解决上述问题，本发明实施例提供了一种显示模组，包括阵列基板和驱动芯片；阵列基板包括第一衬底以及位于第一衬底一侧的第一电容极板和第二电容极板，第一电容极板和第二电容极板形成第一电容，第一电容与驱动芯片电连接；在第一状态下，驱动芯片用于定时为第一电容充电；在第一状态切换为第二状态后，第一电容用于向驱动芯片放电；其中，第一状态为驱动芯片的主电源正常状态，第二状态为驱动芯片的主电源异常状态。In order to solve the above problems, an embodiment of the present invention provides a display module, including an array substrate and a driving chip; the array substrate includes a first substrate and a first capacitor electrode plate and a second capacitor electrode located on one side of the first substrate. plate, the first capacitor plate and the second capacitor plate form a first capacitor, and the first capacitor is electrically connected to the driver chip; in the first state, the driver chip is used to charge the first capacitor regularly; in the first state, it is switched to After the second state, the first capacitor is used to discharge the driving chip; wherein the first state is the normal state of the main power supply of the driving chip, and the second state is the abnormal state of the main power supply of the driving chip.

采用以上方案，可将第一电容作为驱动芯片的备用电源，在驱动芯片的主电源正常时，利用驱动芯片定时为第一电容充电，进而可以在驱动芯片的主电源突然由正常状态切换为异常状态(即异常掉电)后，利用第一电容向驱动芯片放电，由于阵列基板的面积较大，可以利用其空白区域设置第一电容极板和第二电容极板，使第一电容存储较多的电荷，为驱动芯片提供足够的电能，使其将显示面板内的留存电荷彻底释放，彻底解决驱动芯片异常掉电的不良影响，保证显示模组的性能稳定性。With the above solution, the first capacitor can be used as the backup power supply of the driver chip. When the main power supply of the driver chip is normal, the first capacitor can be charged regularly by the driver chip, and then the main power supply of the driver chip can suddenly be switched from the normal state to the abnormal state. After the state (that is, abnormal power failure), the first capacitor is used to discharge the driver chip. Since the area of the array substrate is large, the blank area of the array substrate can be used to set the first capacitor plate and the second capacitor plate, so that the storage of the first capacitor is relatively high. A large amount of electric charge can provide enough power for the driver chip, so that it can completely release the retained charge in the display panel, completely solve the adverse effect of abnormal power failure of the driver chip, and ensure the performance stability of the display module.

以上是本申请的核心思想，基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下，所获得的所有其他实施例，都属于本申请保护的范围。以下将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。The above is the core idea of the present application.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

图1是本发明实施例提供的一种显示模组中阵列基板的剖面结构示意图，如图1所示，本发明实施例提供的显示模组10包括阵列基板100和驱动芯片(未示出)，阵列基板100包括第一衬底110以及位于第一衬底110一侧的第一电容极板121和第二电容极板122，第一电容极板121和第二电容极板122形成第一电容，第一电容与驱动芯片电连接(未示出)；在第一状态下，驱动芯片用于定时为第一电容充电；在第一状态切换为第二状态后，第一电容用于向驱动芯片放电；其中，第一状态为驱动芯片的主电源正常状态，第二状态为驱动芯片的主电源异常状态。1 is a schematic cross-sectional structural diagram of an array substrate in a display module provided by an embodiment of the present invention. As shown in FIG. 1 , thedisplay module 10 provided by an embodiment of the present invention includes anarray substrate 100 and a driving chip (not shown) , thearray substrate 100 includes afirst substrate 110 and afirst capacitor plate 121 and asecond capacitor plate 122 located on one side of thefirst substrate 110. Thefirst capacitor plate 121 and thesecond capacitor plate 122 form thefirst capacitor plate 121 and thesecond capacitor plate 122. capacitor, the first capacitor is electrically connected to the driving chip (not shown); in the first state, the driving chip is used to charge the first capacitor periodically; after the first state is switched to the second state, the first capacitor is used to The driving chip is discharged; wherein, the first state is the normal state of the main power supply of the driving chip, and the second state is the abnormal state of the main power supply of the driving chip.

如前所述，显示模组包括显示面板，显示面板中设置有阵列排布的像素，通过控制各像素的发光状态(例如发光亮度)可实现目标画面的显示。阵列基板100属于显示面板的一部分，总的来说，阵列基板100中主要设置有用于控制各像素的发光状态的阵列排布的控制电路，以及用于驱动各控制电路工作的驱动电路等电路结构，此外还设置有信号走线等结构。不同类型的显示模组所对应的阵列基板的具体结构不同，后续做示例性说明，在此不做赘述。As mentioned above, the display module includes a display panel, and the display panel is provided with pixels arranged in an array, and the display of the target image can be realized by controlling the light-emitting state (eg light-emitting brightness) of each pixel. Thearray substrate 100 is a part of the display panel. In general, thearray substrate 100 is mainly provided with a control circuit for controlling the light-emitting state of each pixel in an array arrangement, and a circuit structure such as a driving circuit for driving the operation of each control circuit. , and also provided with structures such as signal wiring. The specific structures of the array substrates corresponding to different types of display modules are different, which will be exemplified in the following, and will not be repeated here.

本实施例中，可以在阵列基板100的电路结构和信号走线等结构之外的空白区域设置第一电容极板121和第二电容极板122，使第一电容极板121和第二电容极板122沿垂直于第一衬底110所在平面的方向上至少部分交叠，以利用第一电容极板121和第二电容极板122形成第一电容。进一步地，通过将第一电容和驱动芯片电连接，可使第一电容作为驱动芯片的备用电源。示例性的，可以通过走线将第一电容极板121和第二电容极板122分别与驱动芯片电连接，实现第一电容与驱动芯片电连接。In this embodiment, the firstcapacitor electrode plate 121 and the secondcapacitor electrode plate 122 can be set in the blank area outside the circuit structure and the signal wiring structure of thearray substrate 100 , so that the firstcapacitor electrode plate 121 and the secondcapacitor electrode plate 121 and the secondcapacitor electrode plate 121 can be arranged in the blank area. Theelectrode plates 122 are at least partially overlapped in a direction perpendicular to the plane of thefirst substrate 110 to form a first capacitor with the firstcapacitor electrode plate 121 and the secondcapacitor electrode plate 122 . Further, by electrically connecting the first capacitor and the driving chip, the first capacitor can be used as a backup power supply of the driving chip. Exemplarily, the firstcapacitor electrode plate 121 and the secondcapacitor electrode plate 122 may be electrically connected to the driving chip respectively through wires, so as to realize the electrical connection between the first capacitor and the driving chip.

驱动芯片通常包括主电源。示例性的，在主电源正常的状态下，主电源可用于将外部电源的电压转换为驱动芯片内部的各电路模块所需的工作电源的电压，或者其他供电用途，本发明实施例对此不做限定。本实施中，在驱动芯片的主电源正常状态(即第一状态)下，主电源还用于定时为第一电容充电。可选的，主电源可以在设备开机后、显示前，优先为第一电容充电；此外，主电源可以每间隔一帧或多帧画面为第一电容充电一次。本领域技术人员可结合实际需求设定为第一电容充电的频次和时长等参数，本发明实施例对此不作特殊限定。示例性的，驱动芯片在对第一电容充电时，可以分别第一电容极板121和第二电容极板122施加高电平信号和低电平信号。The driver chip usually includes the main power supply. Exemplarily, in the normal state of the main power supply, the main power supply can be used to convert the voltage of the external power supply into the voltage of the working power supply required by each circuit module inside the driving chip, or for other power supply purposes, which is not covered in this embodiment of the present invention. Do limit. In this implementation, in the normal state (ie, the first state) of the main power supply of the driving chip, the main power supply is also used for timing the charging of the first capacitor. Optionally, the main power supply may charge the first capacitor preferentially after the device is turned on and before displaying; in addition, the main power supply may charge the first capacitor once every one or more frames. Those skilled in the art may set parameters such as the frequency and duration of charging of the first capacitor according to actual requirements, which are not particularly limited in this embodiment of the present invention. Exemplarily, when the driver chip charges the first capacitor, thefirst capacitor plate 121 and thesecond capacitor plate 122 may respectively apply a high-level signal and a low-level signal.

进一步地，当驱动芯片由主电源正常状态(即第一状态)切换为主电源异常状态(即第二状态)后，即驱动芯片异常掉电后，第一电容可作为驱动芯片的备用电源为其供电。由于阵列基板100的面积较大，因而可以得到较大的空白区域用于设置第一电容极板121和第二电容极板122，保证第一电容的存储电量，在驱动芯片异常掉电后为其提供足够的电能，使其将显示面板内的留存电荷彻底释放，彻底解决驱动芯片异常掉电的不良影响，保证显示模组的性能稳定性。Further, when the driver chip is switched from the normal state of the main power supply (ie, the first state) to the abnormal state of the main power supply (ie, the second state), that is, after the driver chip is abnormally powered off, the first capacitor can be used as the backup power supply of the driver chip: its power supply. Due to the large area of thearray substrate 100, a large blank area can be obtained for setting thefirst capacitor plate 121 and thesecond capacitor plate 122 to ensure the stored power of the first capacitor. It provides enough power to completely release the retained charge in the display panel, completely solve the adverse effect of abnormal power failure of the driver chip, and ensure the performance stability of the display module.

综上，本发明实施例通过在阵列基板上设置第一电容极板和第二电容极板形成第一电容，并将第一电容与驱动芯片电连接，可将第一电容作为驱动芯片的备用电源，在驱动芯片的主电源正常时，利用驱动芯片定时为第一电容充电，进而可以在驱动芯片的主电源突然由正常状态切换为异常状态(即异常掉电)后，利用第一电容向驱动芯片放电，由于阵列基板的面积较大，可以利用其空白区域设置第一电容极板和第二电容极板，使第一电容存储较多的电荷，为驱动芯片提供足够的电能，使其将显示面板内的留存电荷彻底释放，彻底解决驱动芯片异常掉电的不良影响，保证显示模组的性能稳定性。To sum up, in the embodiment of the present invention, the first capacitor is formed by arranging the first capacitor plate and the second capacitor plate on the array substrate, and the first capacitor is electrically connected to the driving chip, so that the first capacitor can be used as a backup of the driving chip. When the main power supply of the driver chip is normal, the driver chip is used to regularly charge the first capacitor, and then the first capacitor can be used to charge the first capacitor after the main power supply of the driver chip is suddenly switched from a normal state to an abnormal state (ie, abnormal power failure). When the driver chip discharges, due to the large area of the array substrate, the blank area of the array substrate can be used to set the first capacitor plate and the second capacitor plate, so that the first capacitor can store more charges and provide enough power for the driver chip to make it Completely release the retained charge in the display panel, completely solve the adverse effects of abnormal power failure of the driver chip, and ensure the performance stability of the display module.

在上述实施例的基础上，可选驱动芯片内部通常设置有开关器件(例如场效应晶体管)，驱动芯片可以通过其内部的开关器件与第一电容和驱动芯片之间的走线电连接，如此，在主电源正常的状态下，驱动芯片通过控制开关器件周期性地开启，可以定时为第一电容充电。在驱动芯片异常掉电后，可以利用其内部存储的电荷(例如驱动芯片内部电容存储的电荷)开启开关器件，以使第一电容与驱动芯片电气连接，作为驱动芯片的备用电源向其放电。On the basis of the above embodiment, the optional driver chip is usually provided with a switching device (such as a field effect transistor), and the driver chip can be electrically connected to the wiring between the first capacitor and the driver chip through the internal switching device, so that , in the normal state of the main power supply, the driving chip can periodically turn on the switching device by controlling the switching device, and can charge the first capacitor regularly. After the driver chip is abnormally powered off, the switching device can be turned on by using the charge stored in the driver chip (for example, the charge stored in the internal capacitor of the driver chip), so that the first capacitor is electrically connected to the driver chip and discharged as a backup power source of the driver chip.

图2是本发明实施例提供的一种显示模组的俯视结构示意图，如图2所示，阵列基板100还包括栅极驱动电路130、多条扫描线141和多条数据线142；栅极驱动电路130分别与驱动芯片200和多条扫描线141电连接，驱动芯片200与多条数据线142电连接；在第一状态切换为第二状态后，驱动芯片200用于控制栅极驱动电路130向多条扫描线141输出扫描使能信号，以及用于向多条数据线142输出零电平信号。FIG. 2 is a schematic top-view structural diagram of a display module provided by an embodiment of the present invention. As shown in FIG. 2 , thearray substrate 100 further includes agate driving circuit 130 , a plurality ofscan lines 141 and a plurality ofdata lines 142 ; Thedrive circuit 130 is electrically connected to thedrive chip 200 and the plurality ofscan lines 141 respectively, and thedrive chip 200 is electrically connected to the plurality ofdata lines 142; after the first state is switched to the second state, thedrive chip 200 is used to control the gate drive circuit The 130 outputs scan enable signals to the plurality ofscan lines 141 and is used to output zero-level signals to the plurality of data lines 142 .

如图2所示，阵列基板100包括显示区AA，显示区AA内设置有阵列排布的控制电路143，各控制电路143分别与扫描线141和数据线142电连接，在第一状态下，控制电路143用于根据扫描线141的扫描使能信号和数据线142提供的数据信号，控制对应像素的发光状态。参照图2，阵列基板100中的控制电路143与扫描线141和数据线142的连接方式可以是，位于同一行的控制电路143与同一条扫描线141电连接，位于同一列的控制电路143与同一条数据线142电连接，当然，也可以是其他本领域技术人员可知的任意其他连接方式，本发明实施例对此不作限定。As shown in FIG. 2 , thearray substrate 100 includes a display area AA, and controlcircuits 143 arranged in an array are arranged in the display area AA. Eachcontrol circuit 143 is electrically connected to thescan line 141 and thedata line 142 respectively. In the first state, Thecontrol circuit 143 is configured to control the light-emitting state of the corresponding pixel according to the scan enable signal of thescan line 141 and the data signal provided by thedata line 142 . Referring to FIG. 2 , thecontrol circuit 143 in thearray substrate 100 is connected to thescan lines 141 and thedata lines 142 in such a way that thecontrol circuits 143 located in the same row are electrically connected to thesame scan line 141 , and thecontrol circuits 143 located in the same column are connected to thesame scan line 141 . Thesame data line 142 is electrically connected, of course, may also be any other connection manner known to those skilled in the art, which is not limited in this embodiment of the present invention.

进一步地，扫描线141上的扫描使能信号由栅极驱动电路130提供。具体的，栅极驱动电路130包括多个级联设置的移位寄存器，各级移位寄存器可以在驱动芯片提供的时钟信号、电压信号等信号的作用下，依次向对应的扫描线141输出扫描使能信号，以对扫描控制电路143进行逐行扫描，进而驱动芯片可以通过数据线142向处于扫描状态的各个控制电路143传输数据信号，控制对应像素的发光状态，当各行控制电路143依次扫描完毕后，完成一帧画面的显示。Further, the scan enable signal on thescan line 141 is provided by thegate driving circuit 130 . Specifically, thegate driving circuit 130 includes a plurality of shift registers arranged in cascade. The shift registers at each level can sequentially output scan lines to thecorresponding scan lines 141 under the action of clock signals, voltage signals and other signals provided by the driving chip. The enable signal is used to scan thescan control circuit 143 row by row, and then the driver chip can transmit data signals to eachcontrol circuit 143 in the scanning state through thedata line 142 to control the light-emitting state of the corresponding pixel. After the completion, the display of one frame of picture is completed.

以上是在第一状态下，驱动芯片200控制显示面板显示画面的过程。据此可知，在显示过程中驱动芯片突然异常掉电时，控制电路143中仍保持着已经写入的数据信号，数据线142上仍保持着等待写入控制电路143的数据信号，这些数据信号的电压很可能不为零，导致阵列基板100内留存着不被需要的电荷，这些电荷若不能得到彻底释放，会对显示面板的性能产生不良影响。示例性的，控制电路143中通常包括薄膜晶体管，若留存的电荷不能得到彻底释放，容易引起薄膜晶体管特性漂移的问题。The above is the process in which thedriver chip 200 controls the display panel to display images in the first state. It can be seen from this that when the driver chip is suddenly powered off abnormally during the display process, the data signal that has been written in thecontrol circuit 143 still holds, and thedata line 142 still holds the data signal waiting to be written into thecontrol circuit 143. These data signals The voltage of , may not be zero, resulting in unnecessary charges remaining in thearray substrate 100 . If these charges cannot be completely released, the performance of the display panel will be adversely affected. Exemplarily, thecontrol circuit 143 usually includes thin film transistors. If the retained charges cannot be completely released, the problem of characteristic drift of the thin film transistors may easily be caused.

为解决此问题，本实施例在驱动芯片200异常掉电后，利用第一电容为驱动芯片200提供充足的电能，使驱动芯片200控制栅极驱动电路130向多条扫描线141输出扫描使能信号，同时驱动芯片200还向多条数据线142输出零电平信号。如此，可使阵列基板100中的控制电路143均处于扫描状态，从而可以将内部留存的电荷释放至数据线142上，又由于数据线142接收零电平信号，从而可以将留存的电荷衬底释放。示例性的，驱动芯片200可以向栅极驱动电路130中的多级移位寄存器同时输出高电平的驱动信号，以使各级移位寄存器同时向对应的扫描线141输出扫描使能信号，使所有控制电路143均处于扫描状态，以尽快释放留存的电荷。In order to solve this problem, in this embodiment, after thedriving chip 200 is abnormally powered off, the first capacitor is used to provide sufficient power for thedriving chip 200, so that thedriving chip 200 controls thegate driving circuit 130 to output the scan enable to the plurality ofscan lines 141. signal, and thedriving chip 200 also outputs zero-level signals to the plurality of data lines 142 . In this way, thecontrol circuits 143 in thearray substrate 100 can all be in the scanning state, so that the internally retained charges can be released to thedata lines 142, and since thedata lines 142 receive zero-level signals, the retained charges can be transferred to the substrate. freed. Exemplarily, thedriving chip 200 may simultaneously output a high-level driving signal to the multi-level shift registers in thegate driving circuit 130, so that the shift registers of each level output a scan enable signal to thecorresponding scan line 141 at the same time, Allcontrol circuits 143 are in a scanning state to release the retained charges as soon as possible.

图3是本发明实施例提供的另一种显示模组的俯视结构示意图，如图3所示，显示模组10包括透光区Q1，透光区Q1与感光元件所在区域对应设置，可选第一电容极板121和第二电容极板122均为透明电极，且在第一衬底110上的正投影均与透光区Q1在第一衬底110上的正投影交叠。FIG. 3 is a schematic top-view structure diagram of another display module provided by an embodiment of the present invention. As shown in FIG. 3 , thedisplay module 10 includes a light-transmitting area Q1, and the light-transmitting area Q1 is set corresponding to the area where the photosensitive element is located, and is optional. Thefirst capacitor plate 121 and thesecond capacitor plate 122 are both transparent electrodes, and the orthographic projections on thefirst substrate 110 overlap with the orthographic projections of the light-transmitting region Q1 on thefirst substrate 110 .

示例性的，感光元件例如可以是摄像头。为保证透光区Q1的光透过率，改善摄像头的成像质量，阵列基板100与透光区Q1对应的位置可以不设置任何电路结构或信号走线。本实施例中，第一电容极板121与第二电容极板122对应透光区Q1设置，可以利用阵列基板100中原本的空白区域形成第一电容，无需通过改变阵列基板100中的电路布局来得到足够的空白区域，实用性较高，而且阵列基板100中与透光区Q1对应的区域的面积相对较大，因而可以保证第一电容具有较大的电容值，能够为驱动芯片提供充足的电能。Exemplarily, the photosensitive element may be, for example, a camera. In order to ensure the light transmittance of the light-transmitting area Q1 and improve the imaging quality of the camera, the position of thearray substrate 100 corresponding to the light-transmitting area Q1 may not be provided with any circuit structure or signal wiring. In this embodiment, thefirst capacitor plate 121 and thesecond capacitor plate 122 are disposed corresponding to the light-transmitting area Q1, and the original blank area in thearray substrate 100 can be used to form the first capacitor without changing the circuit layout in thearray substrate 100. In order to obtain enough blank area, the practicability is high, and the area of the area corresponding to the light-transmitting area Q1 in thearray substrate 100 is relatively large, so it can ensure that the first capacitor has a large capacitance value, which can provide sufficient power for the driver chip. of electrical energy.

适应性地，当第一电容极板121和第二电容极板122对应透光区Q1设置时，需设置第一电容极板121和第二电容极板122为透明电极，以降低第一电容极板121和第二电容极板122对光透过率的影响。示例性的，透明电极可以采用氧化铟锡(ITO)。Adaptively, when thefirst capacitor plate 121 and thesecond capacitor plate 122 are set corresponding to the light-transmitting area Q1, thefirst capacitor plate 121 and thesecond capacitor plate 122 need to be set as transparent electrodes to reduce the first capacitance The influence of theelectrode plate 121 and the secondcapacitor electrode plate 122 on the light transmittance. Exemplarily, the transparent electrode may be indium tin oxide (ITO).

在上述实施例的基础上，下面基于不同类型的显示模组，对本发明实施例的技术方案做进一步详细说明。On the basis of the above embodiments, the technical solutions of the embodiments of the present invention are further described in detail below based on different types of display modules.

示例性的，显示模组可以为液晶显示模组。相应的，图4是图3中区域S1的一种放大结构示意图，图5是沿图4中BB’截取的显示模组的剖面结构示意图，结合图4和图5所示，当显示模组为液晶显示模组时，可选显示模组10还包括对置基板300以及位于对置基板300与阵列基板100之间的液晶层400；对置基板300包括第二衬底310以及位于第二衬底310靠近液晶层400一侧的环形遮光结构320，环形遮光结构320的内边界3201所围成的区域对应透光区Q1；第一电容极板121在第一衬底110上的正投影的边界至少部分位于环形遮光结构320在第一衬底110上的正投影内；第二电容极板122在第一衬底110上的正投影的边界至少部分位于环形遮光结构320在第一衬底110上的正投影内。如图4所示，环形遮光结构320在第一衬底110上的正投影即环形遮光结构320的内边界3201和环形遮光结构320的外边界3202围成的投影区域。Exemplarily, the display module can be a liquid crystal display module. Correspondingly, FIG. 4 is an enlarged schematic view of the area S1 in FIG. 3 , and FIG. 5 is a schematic cross-sectional view of the display module taken along BB′ in FIG. 4 . When it is a liquid crystal display module, theoptional display module 10 further includes anopposite substrate 300 and aliquid crystal layer 400 located between theopposite substrate 300 and thearray substrate 100 ; theopposite substrate 300 includes asecond substrate 310 and asecond substrate 310 The annular light-shieldingstructure 320 on the side of thesubstrate 310 close to theliquid crystal layer 400 , the area enclosed by theinner boundary 3201 of the annular light-shieldingstructure 320 corresponds to the light-transmitting area Q1 ; the orthographic projection of thefirst capacitor plate 121 on thefirst substrate 110 The boundary is at least partially located in the orthographic projection of the annular light-shieldingstructure 320 on thefirst substrate 110; the boundary of the orthographic projection of thesecond capacitor plate 122 on thefirst substrate 110 is at least partially located in the annular light-shieldingstructure 320 on the first substrate in the orthographic projection on thebase 110 . As shown in FIG. 4 , the orthographic projection of the annularlight shielding structure 320 on thefirst substrate 110 is a projection area enclosed by theinner boundary 3201 of the annularlight shielding structure 320 and theouter boundary 3202 of the annularlight shielding structure 320 .

其中，阵列基板100、对置基板300以及二者之间的液晶层400构成液晶显示面板。通过在对置基板300的第二衬底310靠近液晶层400的一侧设置环形遮光结构320，可以利用环形遮光结构320限定透光区Q1的位置，同时保证自透光区透过的外界环境光线较为集中，避免液晶显示面板内部其他光线的干扰，保证成像质量。Thearray substrate 100 , theopposite substrate 300 and theliquid crystal layer 400 therebetween constitute a liquid crystal display panel. By arranging the annular light-shieldingstructure 320 on the side of thesecond substrate 310 of theopposite substrate 300 close to theliquid crystal layer 400, the annular light-shieldingstructure 320 can be used to limit the position of the light-transmitting area Q1, and at the same time ensure the external environment that passes through the light-transmitting area. The light is more concentrated, avoiding the interference of other light inside the LCD panel and ensuring the image quality.

本领域技术人员可以理解的，第一电容极板121(第二电容极板122)的侧壁与其平行于第一衬底110所在平面的表面之间几乎不可能呈垂直状态，如图5所示，第一电容极板121(第二电容极板122)的侧壁通常具有一定的倾斜角度。本实施例通过设置第一电容极板121在第一衬底110上的正投影的边界至少部分位于环形遮光结构320在第一衬底110上的正投影内，第二电容极板122在第一衬底110上的正投影的边界至少部分位于环形遮光结构320在第一衬底110上的正投影内，可以降低入射光线在第一电容极板121/第二电容极板122的侧壁处发生反射和/或折射而产生炫光的风险，保证感光元件的成像质量。Those skilled in the art can understand that it is almost impossible for the side wall of the first capacitor plate 121 (the second capacitor plate 122 ) to be in a vertical state with the surface parallel to the plane of thefirst substrate 110 , as shown in FIG. 5 . As shown, the side wall of the first capacitor plate 121 (the second capacitor plate 122 ) generally has a certain inclination angle. In this embodiment, the boundary of the orthographic projection of thefirst capacitor plate 121 on thefirst substrate 110 is at least partially located within the orthographic projection of the annular light-shieldingstructure 320 on thefirst substrate 110, and thesecond capacitor plate 122 is located on thefirst substrate 110. The boundary of the orthographic projection on thesubstrate 110 is at least partially located within the orthographic projection of the annular light-shieldingstructure 320 on thefirst substrate 110, which can reduce incident light on the sidewalls of thefirst capacitor plate 121/second capacitor plate 122 The risk of glare caused by reflection and/or refraction at the location ensures the image quality of the photosensitive element.

此外，对于液晶显示面板而言，其工作原理是通过控制电路143产生的电场改变液晶的偏转角度，进而实现对应像素的出光量的控制。本实施例通过设置第一电容极板121在第一衬底110上的正投影的边界至少部分位于环形遮光结构320在第一衬底110上的正投影内，第二电容极板122在第一衬底110上的正投影的边界至少部分位于环形遮光结构320在第一衬底110上的正投影内，可使第一电容极板121和第二电容极板122与显示区内的控制电路143之间具有较大的距离，从而可以降低第一电容在充电后形成的电场影响显示区内的电场，影响液晶偏转进而造成显示异常的风险，保证显示效果。In addition, for the liquid crystal display panel, its working principle is to change the deflection angle of the liquid crystal through the electric field generated by thecontrol circuit 143, thereby realizing the control of the light output of the corresponding pixel. In this embodiment, the boundary of the orthographic projection of thefirst capacitor plate 121 on thefirst substrate 110 is at least partially located within the orthographic projection of the annular light-shieldingstructure 320 on thefirst substrate 110, and thesecond capacitor plate 122 is located on thefirst substrate 110. The boundary of the orthographic projection on thesubstrate 110 is at least partially located within the orthographic projection of the annularlight shielding structure 320 on thefirst substrate 110, so that thefirst capacitor plate 121 and thesecond capacitor plate 122 can be controlled in the display area. There is a large distance between thecircuits 143, so that the electric field formed by the first capacitor after charging can affect the electric field in the display area, which affects the deflection of the liquid crystal and causes the risk of abnormal display, so as to ensure the display effect.

示例性的，图4所示的环形遮光结构320为圆环形，此时，可形成圆形的单盲孔(如Q1所示区域)，适应性地，显示装置可对应该单盲孔设置一个感光元件。由于透光区Q1透过的光线均入射至感光元件中，为避免上述不良现象，优选第一电容极板121在第一衬底110上的正投影的边界位于环形遮光结构320在第一衬底110上的正投影内，第二电容极板122在第一衬底110上的正投影的边界位于环形遮光结构320在第一衬底110上的正投影内。当然，此结构仅为示意并非限定。图6是图3中区域S1的另一种放大结构示意图，如图6所示，在其他实施例中，环形遮光结构320还可以为跑道型，此时，可形成两个圆形的盲孔(如Q2所示区域)，适应性地，显示装置可对应这两个盲孔分别设置一个感光元件，以提高成像质量。对于跑道型的环形遮光结构320，作为一种可行的实施方式，如图6所示，可选第一电容极板121在第一衬底110上的正投影的边界位于环形遮光结构320在第一衬底110上的正投影内，第二电容极板122在第一衬底110上的正投影的边界位于环形遮光结构320在第一衬底110上的正投影内；作为另一种可行的实施方式，图7是图3中区域S1的另一种放大结构示意图，如图7所示，可选第一电容极板121在第一衬底110上的正投影的部分边界位于环形遮光结构320在第一衬底110上的正投影内，其余边界位于两个盲孔的对称中心，第二电容极板122在第一衬底110上的正投影的部分边界位于环形遮光结构320在第一衬底110上的正投影内，其余边界位于两个盲孔的对称中心，只要保证第一电容极板121和第二电容极板122的面积满足存储电量需求，且不影响进入感光元件的光线即可。Exemplarily, the annular light-shieldingstructure 320 shown in FIG. 4 is a circular shape. At this time, a circular single blind hole (such as the area shown in Q1 ) can be formed, and adaptively, the display device can be set corresponding to the single blind hole. a photosensitive element. Since the light transmitted through the light-transmitting region Q1 is all incident on the photosensitive element, in order to avoid the above-mentioned undesirable phenomenon, it is preferable that the boundary of the orthographic projection of thefirst capacitor plate 121 on thefirst substrate 110 is located in the annular light-shieldingstructure 320 on the first substrate. In the orthographic projection on the bottom 110 , the boundary of the orthographic projection of thesecond capacitor plate 122 on thefirst substrate 110 is located in the orthographic projection of the annularlight shielding structure 320 on thefirst substrate 110 . Of course, this structure is only for illustration and not limitation. FIG. 6 is another enlarged schematic diagram of the area S1 in FIG. 3 . As shown in FIG. 6 , in other embodiments, the annular light-shieldingstructure 320 may also be a racetrack type. In this case, two circular blind holes may be formed. (such as the area shown in Q2), adaptively, the display device may be provided with a photosensitive element corresponding to the two blind holes, so as to improve the imaging quality. For the racetrack-shaped annular light-shieldingstructure 320, as a feasible implementation manner, as shown in FIG. In an orthographic projection on asubstrate 110, the boundary of the orthographic projection of thesecond capacitor plate 122 on thefirst substrate 110 is located in the orthographic projection of the annular light-shieldingstructure 320 on thefirst substrate 110; as another possible FIG. 7 is another enlarged schematic view of the area S1 in FIG. 3 , as shown in FIG. 7 , the partial boundary of the orthographic projection of the optionalfirst capacitor plate 121 on thefirst substrate 110 is located in the annular shading In the orthographic projection of thestructure 320 on thefirst substrate 110, the rest of the boundary is located at the symmetry center of the two blind holes, and the partial boundary of the orthographic projection of thesecond capacitor plate 122 on thefirst substrate 110 is located at the annular light-shieldingstructure 320. In the orthographic projection on thefirst substrate 110, the remaining boundaries are located at the symmetrical centers of the two blind holes, as long as the areas of thefirst capacitor plate 121 and thesecond capacitor plate 122 meet the storage power requirements, and do not affect the access to the photosensitive element of light.

需要说明的是，图4、图6和图7中，第一电容极板121和第二电容极板122在第一衬底110上的正投影的边界均为圆滑边界，此设置方式仅为示意并非限定。在其他实施例中，如图8所示，图8是图3中区域S1的另一种放大结构示意图，可选第一电容极板121和第二电容极板122在第一衬底110上的正投影的边界为锯齿状边界。当然，在其他实施例中，可选第一电容极板121和第二电容极板122中的一者在第一衬底110上的正投影的边界为圆滑边界，另一者在第一衬底110上的正投影的边界为锯齿状边界，本发明实施例对此不作限定。具体的，采用圆滑的边界，由于边界的周长相对较小，第一电容极板121/第二电容极板122所在膜层的侧刻量相对较小，有利于保证第一电容极板121和第二电容极板122的具有较大面积，保证第一电容的电容值；采用锯齿状的边界，第一电容极板121和第二电容极板122的对位偏差敏感度较低，有利于保证二者的正对面积，降低对第一电容的电容值的影响，本领域技术人员可结合自身的生产能力选择进行。It should be noted that, in FIG. 4 , FIG. 6 and FIG. 7 , the boundaries of the orthographic projections of thefirst capacitor plate 121 and thesecond capacitor plate 122 on thefirst substrate 110 are all smooth boundaries, and this setting method is only Indication is not limiting. In other embodiments, as shown in FIG. 8 , which is another enlarged schematic diagram of the area S1 in FIG. 3 , the optional firstcapacitor electrode plate 121 and the secondcapacitor electrode plate 122 are on thefirst substrate 110 The boundary of the orthographic projection is a jagged boundary. Of course, in other embodiments, the boundary of the orthographic projection of one of thefirst capacitor plate 121 and thesecond capacitor plate 122 on thefirst substrate 110 may be a smooth boundary, and the other may be on thefirst substrate 110 . The boundary of the orthographic projection on the bottom 110 is a jagged boundary, which is not limited in this embodiment of the present invention. Specifically, a smooth boundary is adopted. Since the perimeter of the boundary is relatively small, the side engraving of the film layer where thefirst capacitor plate 121/thesecond capacitor plate 122 is located is relatively small, which is beneficial to ensure thefirst capacitor plate 121. And thesecond capacitor plate 122 has a larger area to ensure the capacitance value of the first capacitor; using a sawtooth boundary, thefirst capacitor plate 121 and thesecond capacitor plate 122 have a low sensitivity to alignment deviation, and there are It is beneficial to ensure the facing area of the two and reduce the influence on the capacitance value of the first capacitor. Those skilled in the art can choose to perform according to their own production capacity.

此外，图9是图3中区域S1的另一种放大结构示意图，如图9所示，当第一电容极板121和第二电容极板122的边界为锯齿状边界时，二者的锯齿状边界沿垂直于第一衬底110所在平面的方向上可交错设置。In addition, FIG. 9 is another enlarged schematic view of the area S1 in FIG. 3 . As shown in FIG. 9 , when the boundary between thefirst capacitor plate 121 and thesecond capacitor plate 122 is a sawtooth boundary, the sawtooth between the two The shape boundaries may be staggered along a direction perpendicular to the plane of thefirst substrate 110 .

此外，对于跑道型的环形遮光结构320所对应的第一电容极板121和第二电容极板122，其在第一衬底110上的正投影的边界同样可以采用锯齿状边界，在此不再一一示意。In addition, for the firstcapacitor electrode plate 121 and the secondcapacitor electrode plate 122 corresponding to the racetrack-shaped annular light-shieldingstructure 320, the orthographic boundary of the orthographic projection on thefirst substrate 110 can also adopt a zigzag boundary. Indicate again.

图10是本发明实施例提供的一种显示模组的局部剖面结构示意图，图10与图5对应，示出了液晶显示模组的显示区内的剖面结构。如图10所示，可选对置基板300还包括位于第二衬底310靠近液晶层400一侧的滤光层，滤光层包括多个滤光单元330，相邻滤光单元330之间具有遮光结构340；环形遮光结构320与遮光结构340在同一工艺中制备得到。FIG. 10 is a schematic partial cross-sectional structure diagram of a display module provided by an embodiment of the present invention. FIG. 10 corresponds to FIG. 5 and shows a cross-sectional structure in the display area of the liquid crystal display module. As shown in FIG. 10 , the optionalopposite substrate 300 further includes a filter layer located on the side of thesecond substrate 310 close to theliquid crystal layer 400 , and the filter layer includes a plurality offilter units 330 , betweenadjacent filter units 330 . It has a light-shieldingstructure 340; the annular light-shieldingstructure 320 and the light-shieldingstructure 340 are prepared in the same process.

本实施例中，对置基板300也可称之为彩膜基板。滤光层中的多个滤光单元可以包括多个不同颜色的滤光单元，不同颜色的滤光单元330可使不同颜色的光透过。示例性的，多个滤光单元330可以包括红色滤光单元R、绿色滤光单元G和蓝色滤光单元B，红色滤光单元R可使红光透过，绿色滤光单元G可使滤光透过，蓝色滤光单元B可使蓝光透过，通过控制液晶偏转角度，可实现各滤光单元330透光量的控制，进而实现彩色显示。通过在相邻滤光单元330之间设置遮光结构340，如黑矩阵(BM，Black Matrix)，可以防止不同颜色的光发生串扰。环形遮光结构320与遮光结构340均具有遮光效果，因此可以在同一工艺中同时制备得到，以减少工艺步骤，提高生产效率，避免增加液晶显示面板的厚度。In this embodiment, theopposite substrate 300 may also be referred to as a color filter substrate. The multiple filter units in the filter layer may include multiple filter units of different colors, and thefilter units 330 of different colors can transmit light of different colors. Exemplarily, the plurality offilter units 330 may include a red filter unit R, a green filter unit G, and a blue filter unit B. The red filter unit R can transmit red light, and the green filter unit G can transmit red light. The blue filter unit B can transmit blue light, and by controlling the deflection angle of the liquid crystal, the light transmittance of eachfilter unit 330 can be controlled, thereby realizing color display. By arranging alight shielding structure 340, such as a black matrix (BM, Black Matrix), betweenadjacent filter units 330, crosstalk between lights of different colors can be prevented. Both the annular light-shieldingstructure 320 and the light-shieldingstructure 340 have light-shielding effects, so they can be simultaneously prepared in the same process to reduce process steps, improve production efficiency, and avoid increasing the thickness of the liquid crystal display panel.

The 1521 is electrically connected to thedriving chip 200 through thedata line 142 , and thedrain electrode 1522 of the thin film transistor 150 is electrically connected to thepixel electrode 161 . After the thin film transistor 150 is turned on under the control of the scan enable signal transmitted by thescan line 141, the data signal on thedata line 142 is transmitted to thepixel electrode 161 through the thin film transistor 150, and passes through the gap between thepixel electrode 161 and thecommon electrode layer 162 in the corresponding area. The electric field formed between them realizes the control of the deflection angle of the liquid crystal.

Further, considering that the capacitance value is negatively correlated with the distance between the capacitor plates, it is preferable that thefirst capacitor plate 121 and thesecond capacitor plate 122 are respectively in phase with each other along the direction perpendicular to the plane of thefirst substrate 110. Two adjacent conductive film layers are arranged in the same layer.
