实施例1：Example 1:
本实施例提供一种显示面板，该显示面板包括显示屏，显示屏的外层为公共电极层，该显示面板还包括附加电极层，附加电极层位于公共电极层的外侧，且在附加电极层与公共电极层之间间隔设置有绝缘物。This embodiment provides a display panel, the display panel includes a display screen, the outer layer of the display screen is a common electrode layer, the display panel also includes an additional electrode layer, the additional electrode layer is located outside the common electrode layer, and the additional electrode layer An insulator is arranged between the common electrode layer and the common electrode layer.
如图1所示，该显示面板中可划分为显示屏10和触控单元20，其中，显示屏10包括控制层(例如薄膜晶体管，Thin FilmTransistor，简称TFT)、显示层12(例如有机电致发光器件OLED或者受TFT控制而实现背光源光线通过与否的控制的液晶层)和公共电极层13(通常用于提供参考电压)，触控单元20包括公共电极层13、附加电极层21以及设置于公共电极层13和附加电极层21之间的绝缘物22。其中的公共电极层13为显示和触控共用。As shown in FIG. 1 , the display panel can be divided into a display screen 10 and a touch control unit 20, wherein the display screen 10 includes a control layer (such as a thin film transistor, Thin Film Transistor, referred to as TFT), a display layer 12 (such as an organic electro- The light-emitting device OLED or the liquid crystal layer controlled by the TFT to realize the control of whether the light from the backlight passes through) and the common electrode layer 13 (usually used to provide a reference voltage), the touch unit 20 includes the common electrode layer 13, the additional electrode layer 21 and The insulator 22 is disposed between the common electrode layer 13 and the additional electrode layer 21 . The common electrode layer 13 is shared by display and touch control.
其中，公共电极层13和附加电极层21均为板状，采用板状的公共电极层13和附加电极层21，无需在公共电极层13和附加电极层21中形成任何图案，使得该显示面板的结构相对简单；也相应地省去了形成图案的构图工艺，极大地简化了该显示面板的制备工艺。Wherein, the common electrode layer 13 and the additional electrode layer 21 are both plate-shaped, and the plate-shaped common electrode layer 13 and the additional electrode layer 21 do not need to form any patterns in the common electrode layer 13 and the additional electrode layer 21, so that the display panel The structure of the display panel is relatively simple; correspondingly, the patterning process for forming the pattern is omitted, which greatly simplifies the manufacturing process of the display panel.
公共电极层13接地(即接0V电压)，附加电极层21在其相对的顶点上分别施加0V、5V电压。其中相对的顶点是指，如图2A和图2B所示的位于长方形板状的斜对角线上的两个顶点，该两个顶点其一施加0V电压，另一顶点施加5V电压。The common electrode layer 13 is grounded (that is, connected to 0V voltage), and the additional electrode layer 21 applies voltages of 0V and 5V to its opposite vertices respectively. Wherein the opposite vertices refer to two vertices located on the oblique diagonal line of the rectangular plate as shown in FIG. 2A and FIG. 2B , and a voltage of 0V is applied to one of the two vertices, and a voltage of 5V is applied to the other vertices.
同时，如图2B所示，通过在处于相对内层的公共电极层13上施加触控参考电压，使得公共电极层13仅仅作为纯导体，只需一条引出线；并如图2A所示，在处于相对外层的附加电极层21相对的顶点上分别施加0V、5V电压，从而在附加电极层21的边沿形成两对平行线，该两对平行线垂直设置，可设置四条引出线，并以此作为检测触控点的X轴和Y轴电压值的导线。At the same time, as shown in FIG. 2B, by applying a touch reference voltage on the common electrode layer 13 in the opposite inner layer, the common electrode layer 13 is only used as a pure conductor, and only one lead wire is needed; and as shown in FIG. 2A, in Voltages of 0V and 5V are respectively applied to the opposite vertices of the additional electrode layer 21 on the outer layer, so that two pairs of parallel lines are formed on the edge of the additional electrode layer 21. The two pairs of parallel lines are vertically arranged, and four lead-out lines can be provided. This is used as a wire to detect the X-axis and Y-axis voltage values of the touch point.
优选的是，附加电极层21采用透明电极材料或导电高分子材料形成，透明电极材料包括氧化铟镓锌(IGZO)、氧化铟锌(IZO)、氧化铟锡(ITO)、氧化铟镓锡(InGaSnO)、氧化铟(In2O3)、氧化锌(ZnO)、氧化铟锡锌(ITZO)、纳米银线(NanometerAgnanowire，简称NAGW)或碳纳米管(Carbon Nanotube，简称CNT)中的任一种，导电高分子材料包括可转印透明导电膜(Transparent Conductive Transfer Film，简称TCTF)或3，4-乙撑二氧噻吩单体聚合物与聚苯乙烯磺酸盐水溶液(PEDOT:PSS)。采用透明材料形成附加电极层21，因此不会对显示屏10的图像显示造成任何影响。Preferably, the additional electrode layer 21 is formed of a transparent electrode material or a conductive polymer material, and the transparent electrode material includes indium gallium zinc oxide (IGZO), indium zinc oxide (IZO), indium tin oxide (ITO), indium gallium tin oxide ( InGaSnO), indium oxide (In2 O3 ), zinc oxide (ZnO), indium tin zinc oxide (ITZO), nano silver wire (Nanometer Agnanowire, NAGW for short) or carbon nanotube (Carbon Nanotube, CNT for short) One, the conductive polymer material includes transferable transparent conductive film (Transparent Conductive Transfer Film, referred to as TCTF) or 3,4-ethylenedioxythiophene monomer polymer and polystyrene sulfonate aqueous solution (PEDOT:PSS). The additional electrode layer 21 is formed of a transparent material, so it will not have any influence on the image display of the display screen 10 .
绝缘物22为球状或圆柱状，绝缘物均匀或不均匀设置在公共电极层13与附加电极层21之间。优选的是，绝缘物22采用塑胶系、玻璃系或矽氧系的树脂材料形成。例如，该绝缘物22可以为塑胶系的压克力树脂形成的球状粒子(或者说珠状粒子，BeadsSpacer)及光间隔物(Photo Spacer)、玻璃系树脂形成的圆柱状(或者说棒状)粒子、球状粒子及矽氧系树脂形成的球状粒子。该绝缘物22也采用透明材料形成，因此不会对显示屏10的图像显示造成任何影响。而且，该绝缘物22间隔设置于公共电极层13与附加电极层21之间，既能起到使公共电极层13与附加电极层21之间绝缘隔离的目的，又不会在有手指触压显示面板的时候影响附加电极层21的形变，阻碍附加电极层21与公共电极层13接触。The insulator 22 is spherical or cylindrical, and the insulator is uniformly or unevenly disposed between the common electrode layer 13 and the additional electrode layer 21 . Preferably, the insulator 22 is formed of plastic-based, glass-based or silicone-based resin materials. For example, the insulator 22 can be spherical particles (or bead-shaped particles, BeadsSpacer) formed by plastic-based acrylic resin, photo spacers (Photo Spacer), cylindrical (or rod-shaped) particles formed by glass-based resin , spherical particles and spherical particles made of silicone resin. The insulator 22 is also made of a transparent material, so it will not have any influence on the image display of the display screen 10 . Moreover, the insulator 22 is arranged at intervals between the common electrode layer 13 and the additional electrode layer 21, which can not only achieve the purpose of insulating and isolating the common electrode layer 13 and the additional electrode layer 21, but also prevent the contact between the common electrode layer 13 and the additional electrode layer 21. When displaying the panel, it affects the deformation of the additional electrode layer 21 and prevents the additional electrode layer 21 from contacting the common electrode layer 13 .
绝缘物22通过喷洒方式设置于公共电极层13的外侧，附加电极层21通过压合方式与显示屏10形成整体。通过将附加电极层21与显示屏10压合形成一体，即可在显示屏10的基础上整合实现同时具有显示功能和触控功能的叠层结构。而且，采用压合方式形成该叠层结构，相对现有技术在显示屏10外侧贴合外挂式电容触控屏的方式，具有较高的产品良率，能有效降低显示屏10的损坏成本。The insulator 22 is disposed on the outside of the common electrode layer 13 by spraying, and the additional electrode layer 21 is integrally formed with the display screen 10 by pressing. By press-bonding the additional electrode layer 21 and the display screen 10 to form an integral body, a laminated structure with both display and touch functions can be realized on the basis of the display screen 10 . Moreover, the lamination structure is formed by lamination, which has a higher product yield and can effectively reduce the damage cost of the display screen 10 compared to the conventional method of attaching an external capacitive touch screen on the outside of the display screen 10 .
根据上述结构，该显示面板中由公共电极层13和附加电极层21形成了电阻式触控单元20，其中的公共电极层13可分时复用为显示用的公共电压参考端，以及触控用的公共电压参考端。例如，当显示频率为60Hz时，公共电极层13作为显示用的公共电压参考端的时间和作为触控用的公共电压参考端的时间各为1/60秒，依次循环为显示和触控复用。According to the above structure, in the display panel, the resistive touch unit 20 is formed by the common electrode layer 13 and the additional electrode layer 21, wherein the common electrode layer 13 can be time-divisionally multiplexed as a common voltage reference terminal for display, and a touch control unit. The common voltage reference terminal used. For example, when the display frequency is 60 Hz, the time of the common electrode layer 13 as the common voltage reference terminal for display and the common voltage reference terminal for touch control are each 1/60 second, and the display and touch multiplexing are cycled in turn.
在触控过程中，公共电极层13形成触控单元20的下电极，附加电极层21形成触控单元20的上电极，当有手指在附加电极层21上触压而使得附加电极层21与公共电极层13发生接触时，即引起附加电极层21相应位置点的电压改变，形成压降，通过对该电压改变点位置的侦测，即可确定触控点的坐标值，进而确定触控点位置。During the touch process, the common electrode layer 13 forms the lower electrode of the touch unit 20, and the additional electrode layer 21 forms the upper electrode of the touch unit 20. When a finger touches the additional electrode layer 21, the additional electrode layer 21 and When the common electrode layer 13 is in contact, the voltage at the corresponding point of the additional electrode layer 21 changes, forming a voltage drop. By detecting the position of the voltage change point, the coordinate value of the touch point can be determined, and then the touch point can be determined. point location.
为了实现显示面板触控位置的检测，本实施例的显示面板还包括电压感应器、模数转换器和处理器，其中：In order to realize the detection of the touch position of the display panel, the display panel of this embodiment further includes a voltage sensor, an analog-to-digital converter, and a processor, wherein:

在检测过程中，电压感应器分时感测附加电极层21在互相垂直的两个方向上的电压改变；处理器将附加电极层21在互相垂直的两个方向上的电压改变的点分别作为触控点的X坐标值和Y坐标值，从而确定触控点的位置。During the detection process, the voltage sensor senses the voltage changes of the additional electrode layer 21 in two mutually perpendicular directions in time division; The X coordinate value and the Y coordinate value of the touch point, so as to determine the position of the touch point.
具体的，本实施例中确定显示面板实现触控位置的方法为：电压感应器与附加电极层21的一个定点相连，并以此定点为相对零位置参考点(坐标值可视为(0，0)，触控过程为绝对坐标系统检测)当公共电极层13和附加电极层21相接触时即可作一次测量，得到触控点在X轴方向的电压，然后通过处理器计算得到该电压与参考电压值Vref的比值，进而通过电压感应器与附加电极层21的定点的距离，根据该比值计算得到触控点距离该定点的距离，也即得到触控点的X坐标值；接着，在公共电极层13和附加电极层21相接触时(在很短的时间内，比如1/60秒内)再作一次测量，得到触控点在Y轴方向的电压，然后通过处理器计算得到该电压与参考电压值Vref的比值，进而通过电压感应器与附加电极层21的定点的距离，根据该比值计算得到触控点距离该定点的距离，也即得到触控点的Y坐标值；最后，根据触控点的(X，Y)坐标值，从而得到触控点的位置。Specifically, the method for determining the touch position of the display panel in this embodiment is: the voltage sensor is connected to a fixed point of the additional electrode layer 21, and this fixed point is used as a relative zero position reference point (the coordinate value can be regarded as (0, 0), the touch process is an absolute coordinate system detection) When the common electrode layer 13 and the additional electrode layer 21 are in contact, a measurement can be made to obtain the voltage of the touch point in the X-axis direction, and then the voltage is calculated by the processor The ratio to the reference voltage value Vref, and then through the distance between the voltage sensor and the fixed point of the additional electrode layer 21, according to the ratio, the distance between the touch point and the fixed point is calculated, that is, the X coordinate value of the touch point is obtained; then, When the common electrode layer 13 is in contact with the additional electrode layer 21 (within a short period of time, such as 1/60 second), another measurement is made to obtain the voltage of the touch point in the Y-axis direction, and then calculated by the processor The ratio of the voltage to the reference voltage Vref, and then through the distance between the voltage sensor and the fixed point of the additional electrode layer 21, the distance between the touch point and the fixed point is calculated according to the ratio, that is, the Y coordinate value of the touch point is obtained; Finally, the position of the touch point is obtained according to the (X, Y) coordinate value of the touch point.

It can be used in various applications such as flexible display, transparent display, and 3D display. It is easy to understand that the OLED display panel can be flexible or non-flexible, which is not limited here.
