Abstract

The invention provides a touch control display substrate, a touch control display panel and a touch control display device. The touch control display substrate comprises a substrate body,a plurality of first touch control sensing blocks and aplurality of second touch control sensing blocks, wherein first touch control electrode wires are arranged in the first touch control sensing blocks; the second touch control sensing blocks are arranged at the edge of the display area in an array mode and arranged on the outer sides of the first touch control sensing blocks, and second touch control electrode wires are arranged in the second touch control sensing blocks; the area of each first touch control sensing block is larger than that of each second touch control sensing block, and the range of the ratio of the area of each second touch control electrode wire to the area of each first touch control electrode wire is 0.9-1.1. According to the touch control display substrate, the ratio of the area of the second touch control electrode wires in the second touch control sensing block to the area of the first touch control electrode wires in the first touch control sensing block is controlledwithin a small difference range, and therefore the uniformity of the touch control performance of the touch control display substrate is improved.

Description

technical field [0001] The present application relates to the technical field of touch display, in particular to a touch display substrate, a touch display panel and a touch display device. Background technique [0002] With the rapid development of display technology, the touch function has become one of the standard configurations of most display devices, and touch screen panels (Touch Screen Panel, TSP) have gradually spread in people's lives. According to the composition structure, the touch screen can be divided into add-on mode (Add on Mode), surface-covering type (On Cell), embedded type (In Cell) and so on. Among them, the embedded type is to embed the touch electrodes of the touch screen inside the display panel, which can not only reduce the overall thickness of the module, but also reduce the production cost of the touch screen. [0003] For embedded touch screens, capacitive touch panels are widely used. The basic principle is to use tools such as fingers or sty...
