Array substrate, display panel and driving method thereof and display device

Abstract

The invention discloses an array substrate, a display panel and a driving method thereof and a display device. According to one embodiment, the array substrate comprises sub-pixels arranged in an array in the row direction and the column direction and multiple touch electrodes arranged in the row direction; each touch electrode comprises multiple touch sub-electrodes arranged sequentially in the row direction, and each touch sub-electrode provides a data signal to one column of sub-pixels at the display stage; each touch sub-electrode receives a touch detection signal at the touch detection stage. According to the embodiment, the touch sub-electrodes are reused as data lines, therefore, losses of touch signals in the transmission process in the touch electrodes can be effectively reduced, the touch sensitivity of a display screen is improved, and meanwhile driving power consumption can be lowered.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a display panel, a driving method thereof, and a display device. Background technique [0002] Touch screens can be classified into self-capacitive touch screens and mutual-capacity touch screens according to their touch detection principles. In one structure of the mutual capacitive touch display screen, strip electrodes extending along the direction of the data lines are arranged on the array substrate as touch reference electrodes or touch sensing electrodes. When performing touch detection, the drive circuit is connected to the strip electrodes at one end of the strip electrodes, and provides touch reference signals to the strip electrodes or receives touch sensing signals. Usually the driving circuit is arranged at one end of the data line in its extending direction, and the strip electrode has a higher resistance value, and the touch referenc...

AI Technical Summary

Problems solved by technology

Usually the driving circuit is arranged at one end of the data line in its extending direction, and the strip electrode has a higher resistance value, and the touch reference signal is transmitted from the end of the strip electrode closer to the driving circuit to the end farther away from the driving circuit. During the process of one end, signal attenuation will occur; the touch sensing signal will also undergo signal attenuation during the process of transmitting from the end of the strip electrode farther away from the driving circuit to the end closer to the driving circuit, which will cause the strip electrode to be close to the driving circuit. Inconsistencies in the touch signal strength between the end and the remote end, resulting in a decrease in touch sensitivity and an increase in drive power consumption
