Problems solved by technology

Since each sub-pixel group includes the readout line 93, which is located in the sub-pixel area, this will result in a decrease in the pixel aperture ratio (aperture ratio); A sub-pixel group must add at least one touch sensing unit and a reading line coupled thereto, for example, a touch sensing unit and a reading line (not shown in the figure) are added in the red sub-pixel R of each sub-pixel group ), then the pixel aperture ratio will decrease again
In addition, since the readout line 93 and the data line 91 are both located in the same pixel area (for example, in the green sub-pixel G), they are parallel to each other and are separated by a very short distance, the coupling effect existing between the two wires may cause touch The situation where the signal is distorted and the touch event is misjudged

Abstract

The invention discloses a pixel array, comprising a plurality of pixels, a plurality of data lines, a plurality of reading lines and a plurality of gate lines, wherein the data lines and the reading lines are configured between two adjacent pixels in turn; two adjacent pixels at two sides of each data line are coupled to the same data line and coupled to different gate lines; and at least one part of reading lines is coupled to one of two adjacent pixels at two sides. The invention also provides a touch panel comprising the pixel array.

Description

technical field [0001] The present invention relates to a touch device, in particular to an in-cell touch panel and a pixel array thereof. Background technique [0002] Liquid crystal displays are widely used display devices at present. With the maturity of touch screen technology, almost all mobile electronic devices, such as multimedia players, mobile phones and personal digital assistants (PDAs), are equipped with touch liquid crystal screens. to increase the convenience of use. [0003] The existing touch-type LCD screen is additionally provided with a touch panel outside the display panel, which is called an external touch screen. Among them, resistive and capacitive touch panels are widely used due to their simple manufacturing process and low cost. on different terminal applications. However, since the additional touch panel will increase the overall thickness of the touch screen and reduce the light transmittance of the display device, which will affect the brightn...
