Description

一种触摸屏和显示装置Touch screen and display device 技术领域Technical field
本发明涉及显示技术领域，具体地，涉及一种触摸屏和包括该触摸屏的显示装置。The present invention relates to the field of display technologies, and in particular, to a touch screen and a display device including the same.
背景技术Background technique
近几年，小尺寸的触摸屏移动显示产品在市场上占据了相当大的比例。目前，触摸屏按照组成结构可分为：外挂式(Add on Mode)触摸屏、覆盖表面式(On Cell)触摸屏、以及内嵌式(In Cell)触摸屏。其中，由于覆盖表面式触摸屏显示产品只需要在显示面板的表面形成简单的透明触控电极图案(驱动电极和感应电极的图案)，即可实现触摸显示功能，很容易确保成品率，所以覆盖表面式触摸屏显示产品的应用最为广泛。In recent years, small-sized touch-screen mobile display products have occupied a considerable proportion in the market. At present, the touch screen can be divided into an add-on touch screen, an on-cell touch screen, and an in-cell touch screen according to the composition structure. Wherein, since the cover type touch screen display product only needs to form a simple transparent touch electrode pattern (a pattern of a driving electrode and a sensing electrode) on the surface of the display panel, the touch display function can be realized, and the yield is easily ensured, so the surface is covered. Touch screen display products are the most widely used.
目前，单层的覆盖表面式触摸屏中，通常通过曝光显影工艺一次形成驱动电极和感应电极的图形以及它们各自的信号线走线的图形，以形成触控电极图案，触控电极图案通常为透明电极图案。图1示出了现有技术中的触摸屏的触控电极图案，如图1所示，由于触控电极图案4大多由规律性的直线图形组成，并且直线图形通常分布比较密集，因此在视觉上很容易发生摩尔现象，即肉眼能够看到这些直线图形。At present, in a single-layer covered surface type touch screen, a pattern of driving electrodes and sensing electrodes and patterns of their respective signal line traces are usually formed by an exposure developing process to form a touch electrode pattern, and the touch electrode pattern is usually transparent. Electrode pattern. 1 shows a touch electrode pattern of a touch screen in the prior art. As shown in FIG. 1 , since the touch electrode pattern 4 is mostly composed of a regular straight line pattern, and the line pattern is generally densely distributed, it is visually It is easy to happen that the moth phenomenon can be seen by the naked eye.
为了解决这个问题，有些公司试着将组成触控电极图案的直线图形改为弯折的纹路形状，如图2所示，这种形状的图形虽然避免了摩尔现象，但肉眼还是能够看见图形的边缘线，这使得触控电极图案4的整体形状还是能被肉眼观看到，由此导致触摸屏在显示时发生画质劣化现象，影响显示效果。In order to solve this problem, some companies try to change the shape of the line forming the touch electrode pattern into a curved shape, as shown in Fig. 2. Although the shape of the figure avoids the mole phenomenon, the figure can still be seen by the naked eye. The edge line makes the overall shape of the touch electrode pattern 4 still visible to the naked eye, thereby causing deterioration of the image quality when the touch screen is displayed, which affects the display effect.

具体实施方式detailed description
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明所提供的触摸屏和显示装置作进一步详细描述。To make the technical solutions of the present invention better understood by those skilled in the art, the touch screen and display device provided by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
图3示出了本发明本实施例提供的触摸屏，如图3所示，该触摸屏包括触控电极板1和以矩阵形式排列的像素电极2，触控电极板1设置在像素电极2相对于触摸屏的显示面的正投影方向上，在像素电极2相对于触摸屏的显示面的正投影方向上还设置有黑矩阵3，黑矩阵3布置为与任意相邻的像素电极2之间的区域相对应，触控电极板1位于黑矩阵3相对于触摸屏的显示面的 正投影方向上，且黑矩阵3完全遮挡触控电极板1的边缘线。其中，触控电极板1可采用氧化铟锡材料形成。FIG. 3 shows a touch screen provided by the embodiment of the present invention. As shown in FIG. 3 , the touch screen includes a touch electrode plate 1 and pixel electrodes 2 arranged in a matrix. The touch electrode plate 1 is disposed on the pixel electrode 2 relative to the pixel electrode 2 . In the orthographic projection direction of the display surface of the touch screen, a black matrix 3 is further disposed in the front projection direction of the pixel electrode 2 with respect to the display surface of the touch screen, and the black matrix 3 is arranged to be in a region with any adjacent pixel electrode 2 Correspondingly, the touch electrode plate 1 is located on the display surface of the black matrix 3 relative to the touch screen. In the forward projection direction, the black matrix 3 completely blocks the edge line of the touch electrode plate 1. The touch electrode plate 1 can be formed by using an indium tin oxide material.
需要说明的是，在黑矩阵3的图形面积可以忽略不计的情况下，触控电极板1的图形面积恰好等于整数倍的像素电极的图形面积，或者，相邻的触控电极板图形之间的间隔区域的面积恰好等于整数倍的像素电极的图形面积。It should be noted that, in the case where the graphic area of the black matrix 3 is negligible, the graphic area of the touch electrode plate 1 is exactly equal to the integer multiple of the graphic area of the pixel electrode, or between adjacent touch electrode plate patterns. The area of the spacer region is exactly equal to the integer multiple of the pattern area of the pixel electrode.
由于触控电极板1采用透明电极材料制成，而触控电极板1的边缘线又完全被黑矩阵3遮挡，所以，在所述触摸屏显示图像时，任意图形的触控电极板1都不会被人眼看到，从而保证了触摸屏显示时的画面质量。Since the touch electrode plate 1 is made of a transparent electrode material, and the edge line of the touch electrode plate 1 is completely blocked by the black matrix 3, when the touch screen displays an image, the touch electrode plate 1 of any pattern is not It will be seen by the human eye, thus ensuring the picture quality when the touch screen is displayed.

In this embodiment, in terms of display principle, the touch screen may be a liquid crystal display touch screen. In this case, the pixel electrode may be an LCD pixel electrode (liquid crystal display pixel electrode). The touch screen in this embodiment may be a cover type liquid crystal display touch screen (ie, a touch sensor is disposed on the liquid crystal display panel), and the surface liquid crystal display touch screen is simple to prepare. The yield is high and the application is extensive.
本实施例中，触控电极板1包括相互绝缘的驱动电极板和感应电极板，所述驱动电极板和所述感应电极板均采用氧化铟锡材料制成。驱动电极板和感应电极板可以位于同一层。如此设置，能使触控电极板1整体的厚度变薄，进而使触摸屏整体变得更加轻薄。本实施例对驱动电极板和感应电极板的布置不做限定，只要确保驱动电极板和感应电极板之间形成互电容，能够实现触控功能即可。 In this embodiment, the touch electrode plate 1 includes a driving electrode plate and a sensing electrode plate insulated from each other, and the driving electrode plate and the sensing electrode plate are both made of indium tin oxide material. The driving electrode plate and the sensing electrode plate may be located on the same layer. With this arrangement, the thickness of the entire touch electrode plate 1 can be made thinner, and the touch screen as a whole can be made thinner and thinner. In this embodiment, the arrangement of the driving electrode plate and the sensing electrode plate is not limited. As long as the mutual capacitance is formed between the driving electrode plate and the sensing electrode plate, the touch function can be realized.
