Embodiment Construction

[0033] In one aspect of the invention, the invention provides a display substrate. Specifically, a display substrate with a touch function (including a touch unit) is proposed. Those skilled in the art are familiar with the fact that the touch unit needs multiple touch electrodes to detect the touch points. refer to figure 1, each of the plurality of touch electrodes (not shown in the figure) on the display substrate 1000 needs to be connected to the driving module 300 to realize signal transmission or sensing. Those skilled in the art can understand that, even for a display device with a small or medium size, in order to meet the requirements for the detection accuracy of touch points, usually hundreds of touch electrodes need to be provided. It is conceivable that when hundreds of electrodes need to be connected to the same driving module 300 , it will result in a complicated wiring connection structure. If the connection line is too long, it is easily affected by environ...

Abstract

The invention discloses a display substrate, a display device and a method for obtaining touch coordinates. The display substrate comprises a substrate body, a touch unit and multiple drive modules, wherein the substrate body comprises a display region and a wiring region arranged at the periphery of the display region; the touch unit is located in the display region and comprises a plurality of touch electrode sets; the drive modules are arranged in the wiring region, each drive module is at least connected with one touch electrode set, and each touch electrode set is only connected with onedrive module; multiple touch electrodes are connected with the multiple drive modules, and the problem that wiring is complex due to the fact that multiple electrodes in the touch unit are all connected to one drive IC can be avoided.

Description

technical field [0001] The present invention relates to the display field, in particular, to a display substrate, a display device and a method for acquiring touch coordinates. Background technique [0002] With the development of display technology and touch sensing technology, current electronic devices, especially small and medium-sized mobile terminals with human-computer interaction functions, generally carry display panels with touch functions. The above-mentioned electronic device can use a separate touch module to realize the touch function, or integrate the touch function into the touch screen in the display panel. Currently commonly used touch sensing technologies include capacitive touch, resistive touch, nano-touch, electromagnetic touch, embedded infrared touch and other sensing technologies to achieve the acquisition of touch points, but the current touch driver mostly uses a single-board design. [0003] Therefore, the current display substrates, display devi...
