Array substrate, display panel and electronic equipment

Abstract

The invention provides an array substrate, a display panel and electronic equipment. The array substrate comprises a touch circuit and a plurality of touch electrodes which are distributed in an arrayed manner, wherein the touch electrodes are insulated from one another; the touch circuit comprises first switch units, second switch units and a first control module; each two adjacent touch electrodes are connected with each other through the corresponding first switch unit; and each touch electrode is connected with a signal line through the corresponding second switch unit. When the array substrate is in a touch detecting state, the first control module is used for controlling the first switch unit to be switched off, and the adjacent touch electrodes are separated from one another one by one; and moreover, the first control module is used for controlling the second switch units to be switched on one by one, and touch detection of all lines of the touch electrodes is finished sequentially. Compared with the prior art, the array substrate has the advantages that a large number of detection signal lines is omitted, circuit wiring of a whole structure is simplified, wiring space is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to an array substrate, a display panel and electronic equipment. Background technique [0002] see figure 1 , which is an equivalent circuit diagram of an array substrate with a touch function in the prior art. [0003] In the prior art, the common electrode layer is divided into multiple independent units, and each independent unit serves as a touch electrode P. [0004] figure 1 Except for the dotted line connected to the touch detection terminal T, the others are equivalent circuits of the liquid crystal display device. The area where each touch electrode P is located includes a plurality of thin film transistors (TFT, Thin Film Transistor). [0005] figure 1 The middle pulse signal g1-gn is connected as a scan line, such as figure 1 As shown, the scan line is connected to the gate of the TFT in each sub-pixel, and is used to control the switching state of t...

Problems solved by technology

[0009] However, it is necessary to add a lot of detection capacitors CM in the entire array substrate, and each CM is connected to a detection signal line for signal detection, so that the wiring density on the array substrate becomes larger and the process is increased.

Since each detection capacitor needs to be led out by a detection signal line, there are many detection signal lines when large-scale or high-precision touch is required, so the wiring of the entire display panel will be very difficult, and the detection capacitor will also exist. difference, making it difficult to achieve large-size display panels and high-precision display panels
