Description

technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate, a display panel including the array substrate, and a display device. Background technique [0002] Touch screens are divided into self-capacitive touch screens and mutual-capacity touch screens according to their touch control principles. Existing mutual-capacitance touch screens usually use touch-emitting electrodes and touch-sensing electrodes to form mutual capacitance, and detect touch points by measuring the change of charge in the mutual capacitance during touch. [0003] In an existing design of a mutual capacitive touch display screen, strip-shaped touch electrodes are provided on the display panel, and one end of the strip-shaped touch electrodes is connected to a driving circuit through a touch signal line at one end of the extending direction. During touch detection, the drive circuit provides a touch signal to the touch signal line,...

AI Technical Summary

Problems solved by technology

Since the strip-shaped touch electrodes are usually made of a whole strip of ITO (Indium Tin Oxide), which has a large resistance value, the touch signal is transmitted from one end of the strip-shaped touch electrode to the other end of its extension direction. gradually attenuates during the process, so that the strength of the touch signal received at different positions of the strip-shaped touch electrodes is different, thus resulting in different touch sensitivities at different positions on the display panel. The touch sensitivity at one end connected to the control signal line is relatively high, and the touch sensitivity at a position away from the end connected to the touch signal line in its extending direction is low, resulting in poor uniformity of touch detection accuracy of the entire touch display screen. The touch detection accuracy drops, which affects the normal operation of the touch screen
