Problems solved by technology

However, when multiple differential driving circuit chips are used to perform the above actions, these touch units may be connected to different differential driving circuit chips through different transmission structures (such as circuit boards, wire layouts, etc.)
In this way, even when the touch display panel is not touched, the signals received by different differential drive circuit chips may not be consistent, so that the calculation process of the signal difference is easy to be wrong, resulting in touch sensing. the error

Abstract

A touch-sensing display panel includes display units, touch-sensing units, a gate driver circuit, a data driver circuit, and readout circuits. Each display unit includes a switching element, a gate line, a data line, and a pixel electrode. The switching element is connected to the gate line, the data line, and the pixel electrode. The touch-sensing units includes a first, a second, and a third touch-sensing units. Each touch-sensing unit includes a sensing element and a sensing line electrically connected to the sensing element. The gate driver circuit is electrically connected to the gate line. The data driver circuit is connected to the data line. The readout circuit includes adjacent first and second readout circuits. The sensing line of the first touch-sensing unit is connected to the first readout circuit. The sensing line of the second touch-sensing unit is connected to the first and the second readout circuits simultaneously.

Description

technical field [0001] The present invention relates to a touch display panel, and in particular to a touch display panel using differential signals to calculate touch positions. Background technique [0002] With the advancement of display technology, people can make their lives more convenient with the assistance of displays. In order to achieve the characteristics of lightness and thinness of displays, flat panel displays (FPDs) have become the current mainstream. In recent years, all kinds of electronic products are constantly moving towards the direction of easy operation, small size and large screen size, especially portable electronic products have stricter requirements on volume and screen size. Therefore, many electronic products integrate the touch-sensitive design with the display panel, so as to omit the space required for the keyboard or control keys, thereby expanding the configurable area of ​​the screen. [0003] Generally speaking, a touch display panel inc...
