Problems solved by technology

[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 actual display brightness and the ideal brightness, affecting the display effect

Abstract

The embodiment of the invention discloses an array substrate, a display panel and a display device. The array substrate comprises a pixel circuit, the pixel circuit comprises a driving module, and thecontrol end of the driving module is electrically connected with a first node; a first initialization module, wherein a second end of the first initialization module is electrically connected with the first node; a threshold compensation module, wherein the second end of the threshold compensation module is electrically connected with the first node; a data writing module which is used for writing the data signal into the first node; a storage module, wherein the first end of the storage module is electrically connected with the first power supply signal line, and a second end of the storagemodule is electrically connected with the first node; the array substrate further comprises a shielding layer, the shielding layer is electrically connected with the first power signal line, and in the signal lines electrically connected with the first node, at least part of the signal lines and the shielding layer are overlapped in an insulated mode in the direction perpendicular to the plane where the array substrate is located. According to the technical scheme, crosstalk caused by coupling capacitance in the pixel circuit can be reduced, and the display effect is improved.

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...
