以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.
本发明旨在提供一种新的触控基板和显示装置。作为本发明的一个方面，提供一种触控基板10，如图1至图3所示，触控基板10包括衬底基板100和设置在衬底基板100上的触控单元层，所述触控单元层包括排列为多行多列的多个触控单元200。每个触控单元200都包括x触控子单元210和y触控子单元220。x触控子单元210用于确定触控点在x方向的坐标，y触控子单元220用于确定触控点在y方向的坐标，其中：The present invention aims to provide a new touch substrate and display device. As an aspect of the present invention, a touch substrate 10 is provided. As shown in FIG. 1 to FIG. 3 , the touch substrate 10 includes a base substrate 100 and a touch unit layer disposed on the base substrate 100 . The control unit layer includes a plurality of touch control units 200 arranged in rows and columns. Each touch unit 200 includes an x touch subunit 210 and a y touch subunit 220 . The x touch subunit 210 is used to determine the coordinates of the touch point in the x direction, and the y touch subunit 220 is used to determine the coordinates of the touch point in the y direction, wherein:
x触控子单元210包括第一电容和位于所述第一电容的电极之间的第一磁感应介质块211，y触控子单元220包括第二电容和位于所述第二电容的电极之间的第二磁感应介质块221。第一磁感应介质块211和第二磁感应介质块221均由磁感应介质材料制成，所述磁感应介质材料的介电常数随该磁感应介质材料所处环境中的磁场的变化而变化。The x touch subunit 210 includes a first capacitor and a first magnetic induction medium block 211 located between electrodes of the first capacitor, and the y touch subunit 220 includes a second capacitor and between electrodes of the second capacitor The second magnetic induction medium block 221 .

容易理解的是，在本发明中，当手指靠近触控单元200时，手指所产生的生物磁场会改变第一磁感应介质块211和第二磁感应介质块221周围的磁场，从而改变第一磁感应介质块211和第二磁感应介质块221的介电常数。而第一磁感应介质块211位于所述第一电容的电极之间，第二磁感应介质块221位于所述第二电容的电极之间，因此当第一磁感应介质块211和第二磁感应介质块221的介电常数改变时，所述第一电容与所述第二电容的电容量也将随之改变，从而可以通过检测电容大小的方式来检测触摸点的位置，实现触摸检测功能。It is easy to understand that in the present invention, when the finger is close to the touch unit 200, the biomagnetic field generated by the finger will change the magnetic field around the first magnetic induction medium block 211 and the second magnetic induction medium block 221, thereby changing the first magnetic induction medium The dielectric constants of the block 211 and the second magnetically inductive dielectric block 221 . The first magnetic induction medium block 211 is located between the electrodes of the first capacitor, and the second magnetic induction medium block 221 is located between the electrodes of the second capacitor. Therefore, when the first magnetic induction medium block 211 and the second magnetic induction medium block 221 When the dielectric constant of , changes, the capacitance of the first capacitor and the second capacitor will also change accordingly, so that the position of the touch point can be detected by detecting the size of the capacitance to realize the touch detection function.

本发明对如何利用各x触控子单元210确定触控点在x方向的坐标不作具体限定，作为本发明的一种优选实施方式，如图1所示，所述第一电容包括第一x电极212和第二x电极213。第一x电极212设置在第一磁感应介质块211与衬底基板100成角度的第一侧面，第二x电极213设置在第一磁感应介质块211与衬底基板100成角度的第二侧面，所述第一侧面和所述第二侧面是第一磁感应介质块211的两个相对的侧面。位于同一列的所有触控单元200中的x触控子单元210的第一x电极212互相电连接，位于同一列的触控单元200中的所有x触控子单元210的第二x电极213互相电连接。The present invention does not specifically limit how to use each x touch sub-unit 210 to determine the coordinates of the touch point in the x direction. As a preferred embodiment of the present invention, as shown in FIG. 1 , the first capacitor includes a first x electrode 212 and second x electrode 213.

The first x electrodes 212 of the x touch subunits 210 in all touch units 200 in the same column are electrically connected to each other, and the second x electrodes 213 of all the x touch subunits 210 in the touch units 200 in the same column electrically connected to each other.
为了便于检测每一触控单元200中第一电容的电极片之间的电容变化，本发明通过将位于同一列的所有触控单元200中的x触控子单元210的第一x电极212互相电连接，并将位于同一列的触控单元200中的所有x触控子单元210的第二x电极213互相电连接。此时，同一列的各个触控单元200中的第一x电极212与第二x电极213组成的多个电容器并联在一起，此时只需向多个并联的电容器两端输入一个电位差，当该列中的一个触控单元200受手指产生的生物磁场的影响时，该触控单元200中的第一x电极212与第二x电极213之间的电容发生改变，在该触控单元200中的第一x电极212与第二x电极213上的电荷也将发生改变，从而可以在多个并联的电容器的两端检测到电流。最后根据检测到电流的列数即可确定触控位置的列坐标(可以是该触控位置对应的触控单元200的列数，即x坐标)。In order to facilitate the detection of the capacitance change between the electrode sheets of the first capacitor in each touch unit 200, the present invention makes the first x electrodes 212 of the x touch sub-units 210 in all touch units 200 in the same column mutually The second x electrodes 213 of all the x touch sub-units 210 in the touch unit 200 in the same column are electrically connected to each other. At this time, multiple capacitors composed of the first x electrodes 212 and the second x electrodes 213 in each touch unit 200 in the same column are connected in parallel, and only a potential difference needs to be input across the multiple parallel capacitors. When one touch unit 200 in the row is affected by the biomagnetic field generated by the finger, the capacitance between the first x electrode 212 and the second x electrode 213 in the touch unit 200 changes, and the The charge on the first x-electrode 212 and the second x-electrode 213 in 200 will also change, so that current can be detected across multiple parallel capacitors. Finally, the column coordinates of the touch position can be determined according to the column number of the detected current (which may be the column number of the touch unit 200 corresponding to the touch position, that is, the x coordinate).
同样地，本发明对如何利用各y触控子单元220确定触控点在x方向的坐标不作具体限定，作为本发明的一种优选实施方式，如图1所示，所述第二电容包括第一y电极222和第二y电极223。第一y电极222设置在第二磁感应介质块221与衬底基板100成角度的第三侧面，第二y电极223设置在第二磁感应介质块221与衬底基板100成角度的第四侧面，所述第三侧面和所述第四侧面是第二磁感应介质块221的两个相对的侧面。位于同一行的所有触控单元200中的y触控子单元220的第一y电极222互相电连接，位于同一行的所有触控单元200中的y触控子单元220的第二y电极223互相电连接。Similarly, the present invention does not specifically limit how to use each y touch sub-unit 220 to determine the coordinates of the touch point in the x direction. As a preferred embodiment of the present invention, as shown in FIG. 1 , the second capacitor includes The first y electrode 222 and the second y electrode 223 . The first y electrode 222 is arranged on the third side of the second magnetic induction medium block 221 angled with the base substrate 100 , the second y electrode 223 is arranged on the fourth side of the second magnetic induction medium block 221 angled with the base substrate 100 , The third side and the fourth side are two opposite sides of the second magnetic induction medium block 221 . The first y electrodes 222 of the y touch subunits 220 in all the touch units 200 in the same row are electrically connected to each other, and the second y electrodes 223 of the y touch subunits 220 in all the touch units 200 in the same row are electrically connected to each other. electrically connected to each other.
为了便于检测每一触控单元200中第二电容的电极片之间的电容变化，本发明通过将位于同一行的所有触控单元200中的y触控子单元220的第一y电极222互相电连接，并将位于同一行的触控单元200中的所有y触控子单元220的第二y电极223互相电连接。此时，同一行的各个触控单元200中的第一y电极222与第二y电极223组成的多个电容器并联在一起，此时只需向多个并联的电容器两端输入一个电位差，当该行中的一个触控单元200受手指产生的生物磁场的影响时，该触控单元200中的第一y电极222与第二y电极223之间的电容发生改变，在该触控单元200中的第一y电极222与第二y电极223上的电荷也将发生改变，从而可以在多个并联的电容器的两端检测到电流。最后根据检测到电流的行数即可确定触控位置的行坐标(可以是该触控位置对应的触控单元200的行数，即y坐标)。In order to facilitate the detection of the capacitance change between the electrode sheets of the second capacitor in each touch unit 200, in the present invention, the first y electrodes 222 of the y touch sub-units 220 in all the touch units 200 in the same row are mutually The second y electrodes 223 of all y touch sub-units 220 in the touch unit 200 in the same row are electrically connected to each other. At this time, multiple capacitors composed of the first y electrode 222 and the second y electrode 223 in each touch unit 200 in the same row are connected in parallel. When one touch unit 200 in the row is affected by the bio-magnetic field generated by the finger, the capacitance between the first y-electrode 222 and the second y-electrode 223 in the touch unit 200 changes. The charge on the first y-electrode 222 and the second y-electrode 223 in 200 will also change so that current can be detected across multiple capacitors connected in parallel. Finally, the row coordinates of the touch position (which may be the row number of the touch unit 200 corresponding to the touch position, that is, the y coordinate) can be determined according to the row number of the detected current.
本发明对所述第一侧面、所述第二侧面、所述第三侧面和所述第四侧面的方向以及各侧面与衬底基板100之间的角度不作具体限定。为了便于触控基板10中各电极之间连接线的排布，优选地，如图1所示，所述第一侧面和所述第二侧面是第一磁感应介质块211的两个沿行方向(即图中x方向)相对的侧面；所述第三侧面和所述第四侧面是第二磁感应介质块221的两个沿列方向(即图中y方向)相对的侧面。The present invention does not specifically limit the directions of the first side surface, the second side surface, the third side surface, and the fourth side surface, and the angle between each side surface and the base substrate 100 . In order to facilitate the arrangement of the connection lines between the electrodes in the touch substrate 10, preferably, as shown in FIG. (ie the x direction in the figure) opposite sides; the third side and the fourth side are two opposite sides of the second magnetic induction medium block 221 along the column direction (ie the y direction in the figure).
本发明对第一磁感应介质块211和第二磁感应介质块221的材料不作具体限定，只要该材料能够满足在不同磁场环境下具有不同的介电常数即可。例如，作为本发明的一种可选实施方式，所述磁感应介质材料包括光子晶体材料。The present invention does not specifically limit the materials of the first magnetic induction medium block 211 and the second magnetic induction medium block 221, as long as the materials can satisfy different dielectric constants under different magnetic field environments. For example, as an optional embodiment of the present invention, the magnetic induction medium material includes a photonic crystal material.
光子晶体(photonic crystal)是一种介电常数和折射率均随空间周期性变化的新型光学微结构材料。经过本发明的发明人研究发现，光子晶体能够在磁场的影响下改变其内部材料的空间位置，从而使得该材料的介电常数和折射率也随之改变。Photonic crystal is a new type of optical microstructure material whose dielectric constant and refractive index both vary with spatial periodicity. The inventors of the present invention have found that the photonic crystal can change the spatial position of its internal material under the influence of a magnetic field, so that the dielectric constant and refractive index of the material are also changed accordingly.
当第一磁感应介质块211和第二磁感应介质块221的材料为光子晶体材料时，本发明还提供一种利用光子晶体材料的特性实现指纹识别的优选方案，具体地：When the materials of the first magnetic induction medium block 211 and the second magnetic induction medium block 221 are photonic crystal materials, the present invention also provides a preferred solution for realizing fingerprint identification by utilizing the characteristics of photonic crystal materials, specifically:
如图2至图4所示，触控基板10还包括光敏单元层，所述光敏单元层包括一一对应地设置在触控单元200背离衬底基板100的表面上的多个光敏单元300，光敏单元300中设置有光敏元件，所述光敏元件中通过的电信号能够随照射在该感光片上的光信号的强度变化而变化。需要指出的是，所述触控基板10还可以包括探测线，所述探测线用于向所述光敏元件中输入和输出电信号。As shown in FIG. 2 to FIG. 4 , the touch substrate 10 further includes a photosensitive unit layer, and the photosensitive unit layer includes a plurality of photosensitive units 300 disposed on the surface of the touch unit 200 facing away from the base substrate 100 in a one-to-one correspondence. The photosensitive unit 300 is provided with a photosensitive element, and the electrical signal passing through the photosensitive element can change with the intensity of the light signal irradiated on the photosensitive sheet. It should be noted that the touch substrate 10 may further include detection lines, and the detection lines are used for inputting and outputting electrical signals to the photosensitive element.
在本发明中，当第一磁感应介质块211和第二磁感应介质块221的材料为光子晶体材料时，还能够配合指纹检测电路实现触控功能与指纹识别功能的结合。在手指表面未覆盖在触控基板10上时，来自背光源的光线经过第一磁感应介质块211和第二磁感应介质块221以及光敏单元300中，此时所述光敏元件受到正常背光光线的照射，使得所述光敏元件中通过的电流为正常电流；In the present invention, when the materials of the first magnetic induction medium block 211 and the second magnetic induction medium block 221 are photonic crystal materials, the combination of the touch function and the fingerprint recognition function can also be realized with the fingerprint detection circuit. When the surface of the finger is not covered on the touch substrate 10, the light from the backlight passes through the first magnetic induction medium block 211, the second magnetic induction medium block 221 and the photosensitive unit 300. At this time, the photosensitive element is irradiated by normal backlight light. , so that the current passing through the photosensitive element is a normal current;
当手指的表面覆盖在触控基板10上时，照射在指纹的谷(图2中b区域所示)所在位置的背光光线可以自由射出触控基板10，所述光敏元件接收到的光强不变，因此该光敏元件中通过的电流仍然为正常电流；而在指纹的脊(图2中a区域所示)所覆盖的位置，触控基板10的表面外的空气介质被人体取代，此时由于出光面材料的折射率过大，特定波长的背光光线在交界处发生全反射，再次照射在所述光敏元件上，此时所述光敏元件接收到的光强增大，使得所述光敏元件中通过的电流高于正常电流值。此时，只需要检测各个位置的光敏单元300中的光敏元件中通过的电流，即可得到指纹的形貌。When the surface of the finger is covered on the touch substrate 10, the backlight light irradiated at the position of the valley of the fingerprint (shown in the area b in FIG. 2) can freely exit the touch substrate 10, and the light intensity received by the photosensitive element is not Therefore, the current passing through the photosensitive element is still the normal current; and at the position covered by the ridge of the fingerprint (shown as area a in FIG. 2 ), the air medium outside the surface of the touch substrate 10 is replaced by the human body. Because the refractive index of the material on the light-emitting surface is too large, the backlight light of a specific wavelength is totally reflected at the junction and irradiated on the photosensitive element again. At this time, the light intensity received by the photosensitive element increases, so that the photosensitive element The current passing through is higher than the normal current value. At this time, it is only necessary to detect the current passing through the photosensitive elements in the photosensitive unit 300 at each position, and then the shape of the fingerprint can be obtained.
本发明提供的触控基板10不仅能够实现触控功能与指纹识别功能的结合，并且该指纹识别功能通过光线的全反射原理实现，由于光线之间不存在互相干扰、电荷残留等问题，与现有的电容式、压电式指纹识别方案相比，提高了指纹识别信号的信噪比和抗干扰能力。The touch substrate 10 provided by the present invention can not only realize the combination of the touch function and the fingerprint identification function, but also realize the fingerprint identification function through the principle of total reflection of light. Compared with some capacitive and piezoelectric fingerprint identification schemes, the signal-to-noise ratio and anti-interference ability of fingerprint identification signals are improved.
本发明对所述光敏元件的具体结构不作具体限定，可选地，所述光敏元件包括光敏二极管、光敏电阻和光敏三极管中的任意一者。The present invention does not specifically limit the specific structure of the photosensitive element. Optionally, the photosensitive element includes any one of a photodiode, a photoresistor, and a phototransistor.
本发明对触控单元200之间和光敏单元300之间的填充材料不作具体限定，例如，如图2所示，触控基板10还包括平坦化层400，所述平坦化层400的材料为透明材料。The present invention does not specifically limit the filling material between the touch units 200 and between the photosensitive units 300. For example, as shown in FIG. 2, the touch substrate 10 further includes a planarization layer 400, and the material of the planarization layer 400 is Transparent material.
作为本发明的第二个方面，提供一种显示面板1。如图6所示，显示面板1包括显示基板20和设置在显示基板的出光侧的触控基板，所述触控基板为前面所述的触控基板10。As a second aspect of the present invention, a display panel 1 is provided. As shown in FIG. 6 , the display panel 1 includes a display substrate 20 and a touch substrate disposed on the light emitting side of the display substrate, and the touch substrate is the aforementioned touch substrate 10 .
本发明提供的显示面板1仅通过感应手指产生的生物磁场即可定位手指位置，使用时手指无需接触显示面板1，提高了用户体验。The display panel 1 provided by the present invention can locate the position of the finger only by sensing the biomagnetic field generated by the finger, and the finger does not need to touch the display panel 1 during use, which improves the user experience.
作为本发明的第三个方面，提供一种显示装置，所述显示装置包括前面所述的触控基板10。As a third aspect of the present invention, a display device is provided, and the display device includes the aforementioned touch substrate 10 .
本发明提供的显示装置仅通过感应手指产生的生物磁场即可定位手指位置，使用时手指无需接触触控基板10，提高了用户体验。The display device provided by the present invention can locate the position of the finger only by sensing the biomagnetic field generated by the finger, and the finger does not need to touch the touch substrate 10 during use, thereby improving user experience.
优选地，如图7所示，所述显示装置还包括坐标确定模块2，坐标确定模块2用于根据x触控子单元210和y触控子单元220输出的信号确定触摸点的坐标。Preferably, as shown in FIG. 7 , the display device further includes a coordinate determination module 2 for determining the coordinates of the touch point according to the signals output by the x touch subunit 210 and the y touch subunit 220 .
容易理解的是，这里“输出的信号”是指各第一电容和第二电容的电压变化量。当手机靠近触控位置的触控单元200时，该位置的触控单元200中第一电容和第二电容的电压均发生改变，此时通过坐标确定模块2来确定发生变化的第一电容的列坐标(即x坐标)和发生变化的第二电容的行坐标(即y坐标)即可得到触摸点的坐标。It is easy to understand that the "output signal" here refers to the voltage variation of each of the first capacitor and the second capacitor. When the mobile phone is close to the touch unit 200 at the touch position, the voltages of the first capacitor and the second capacitor in the touch unit 200 at this position both change. At this time, the coordinate determination module 2 determines the voltage of the changed first capacitor. The coordinates of the touch point can be obtained from the column coordinates (ie, the x coordinates) and the row coordinates (ie, the y coordinates) of the changed second capacitor.
当触控单元200还包括光敏单元300时，优选地，所述显示装置还包括指纹识别模块，所述指纹识别模块用于根据所述光敏元件输出的信号确定指纹形貌。When the touch control unit 200 further includes a photosensitive unit 300, preferably, the display device further includes a fingerprint identification module, and the fingerprint identification module is configured to determine the fingerprint shape according to the signal output by the photosensitive element.
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。It can be understood that the above embodiments are only exemplary embodiments adopted to illustrate the principle of the present invention, but the present invention is not limited thereto. For those skilled in the art, without departing from the spirit and essence of the present invention, various modifications and improvements can be made, and these modifications and improvements are also regarded as the protection scope of the present invention.
