Problems solved by technology

[0002] The self-capacitive touch panel has been widely used in the field of display devices, but under the premise of ensuring the touch resolution, there is a requirement for the size and width of the touch unit. The existing embedded self-capacitive touch panels include Most of the touch units adopt square (Block Pattern) design, and the embedded self-capacitive touch panel requires a large number of touch units
[0003] In the prior art, each touch unit is connected to the corresponding touch metal wire through a separate touch channel, and each effective touch metal wire is connected to a touch unit and a touch channel. As the size of the embedded self-capacitive touch panel increases, the number of touch units increases, which leads to a corresponding increase in the number of touch metal wires and touch channels, thereby increasing the size and cost of the embedded self-capacitive touch panel

Abstract

The invention discloses an array substrate, a display panel and electronic equipment. The array substrate comprises a touch area and multiple touch connecting cables, and the touch area comprises multiple touch units and multiple first switching circuits; the multiple touch units are divided into multiple touch unit sets, each touch unit set comprises a first touch unit and a second touch unit, and each touch unit set corresponds to one touch connecting cable; the first touch units are directly connected with the touch connecting cables; the second touch units are connected with the touch connecting cables through the first switching circuits to make original signals input into the first switching circuits switched into first switching signals, wherein the waveform shape and / or the strength of the first switching signals are / is different from that / those of the original signals. The quantity of the touch connecting cables can be reduced.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to an array substrate, a display panel and electronic equipment. Background technique [0002] The self-capacitive touch panel has been widely used in the field of display devices, but under the premise of ensuring the touch resolution, there is a requirement for the size and width of the touch unit. The existing embedded self-capacitive touch panels include Most of the touch units in the world adopt a square (Block Pattern) design, and the embedded self-capacitive touch panel requires a large number of touch units. [0003] In the prior art, each touch unit is connected to the corresponding touch metal wire through a separate touch channel, and each effective touch metal wire is connected to a touch unit and a touch channel. As the size of the embedded self-capacitive touch panel increases, the number of touch units increases, resulting in a corresponding in...
