Description

technical field

[0001] Embodiments of the present invention relate to display technologies, and in particular to an array substrate, a display panel and a display device. Background technique

[0002] With the development of display technology, Organic Light Emitting Diode (OLED) displays have been more and more widely used in the display field due to their advantages such as active light emission, wide viewing angle, high contrast ratio, low power consumption, and fast response speed. , and gradually replace the traditional liquid crystal display (Liquid Crystal Display, LCD).

[0003] In the pixel circuit of an Active-Matrix Organic Light Emitting Diode (AMOLED), there is a coupling capacitance between the wiring connected to the gate of the drive transistor and the data signal line. Since the OLED is a current-driven element, the existence of the coupling capacitance It will cause the current flowing through the OLED to change, resulting in a difference between the actua...
