Array substrate and display panel

Abstract

The invention provides an array substrate and a display panel. The array substrate comprises a display region and a frame region surrounding the display region, wherein a public electrode layer, a touch control wiring layer and a grid layer are arranged in the display region; the public electrode layer comprises multiple public electrode units; the touch control wring layer comprises multiple first touch control wires electrically connected with the public electrode units; the grid layer comprises multiple grid wires extending in the first direction. The display region further comprises multiple second touch control wires, wherein the second touch control wires are parallel with the grid wires, and each public electrode unit is electrically connected with the corresponding second touch control wire through a via hole; multiple first switches and test leads extending in the second direction are arranged in the frame region, at least one end of each second touch control wire is electrically connected with one corresponding first switch, and the test leads are electrically connected with the first switches. With the adoption of the array substrate and the display panel, the display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display panel for improving panel display effect. Background technique [0002] With the development of human-computer interaction technology, touch technology is increasingly used on various displays. Capacitive touch technology is widely used due to its advantages of wear resistance, long life, low maintenance cost for users, and support for gesture recognition and multi-touch. [0003] Capacitive touch technology can be divided into self-capacitive touch technology and mutual-capacitive touch technology according to the detection method of capacitance between different objects. Self-capacitive touch technology detects the presence, position, and motion of an input object on a touch screen based on changes in capacitance between the input object and electrodes. The mutual capacitive touch technology detects the existence, position and movemen...

AI Technical Summary

Problems solved by technology

[0008] 1) The resistance of the touch trace electrically connected to the top common electrode is much larger than the resistance of the touch trace electrically connected to the bottom common electrode, resulting in the display of harsh screens (dotcheck / pixelcheck). There are visible defects at the top;

[0009] 2) It is impossible to eliminate the above resistance difference by shorting the common electrode through the switching element and the test lead;

[0010] 3) For large-size (8 inches and above) display panels, the resistance difference caused by it is greater, which aggravates the phenomenon of poor display
