Display panel as well as test method and application method thereof

Abstract

The invention provides a display panel as well as a test method and an application method thereof. The display panel comprises a substrate, a first touch electrode group, a second touch electrode group and a driving module, wherein the substrate comprises a display area and a non-display area; the first touch electrode group comprises a plurality of first touch electrodes in the display area of the substrate; each first touch electrode is electrically connected with a first input end through a touch signal output wire and a first switch device; the second touch electrode group comprises a plurality of touch electrodes in the display area of the substrate; each second touch electrode is electrically connected with a second input end through a touch signal output wire and a first switch device; the first touch electrodes and the second touch electrodes form a touch electrode array; the driving module is electrically connected with a control end and the second input end of each first switch device, respectively; and the driving module is at least electrically connected with the first input end through a second switch device. According to the display panel as well as the test method and the application method thereof, the non-uniform display caused by non-uniform voltage of public electrodes can be improved, and the driving ability of the public electrodes can be strengthened.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a testing method and a using method thereof. Background technique [0002] Touchscreens are becoming more popular due to their ease of use, operational versatility, falling prices and steadily increasing yields. The touch screen can be divided into plug-in type and built-in type according to its setting position. The plug-in type can position the panel with touch function in front of the display, and the touch surface covers the visible area of ​​the display area to realize touch control. Built-in type, the touch function is integrated on the panel, and the protective glass is pasted on the outside, and the user can realize the operation by touching the screen with a finger. [0003] In order to further reduce the complexity of the manufacturing process and the thickness of the display panel, a display panel in which common electrodes are multiplexed as...

Problems solved by technology

like image 3 As shown, each of the first self-capacitive touch electrodes 1' and the second self-capacitive touch electrodes 2' in the display panel are multiplexed as common electrodes. However, in the prior art, the common electrodes will obtain different drive voltage ( image 3 Different filling patterns represent different driving voltages), so that the display brightness of the pixel area corresponding to the common electrode is uneven

Obviously, the uneven voltage between each common electrode may cause the overall display effect to look uneven, which seriously affects the display effect of the display panel.
