Abstract

The invention discloses an OLED array substrate, a display panel and a display device, and relates to the technical field of display, and the OLED array substrate comprises a substrate, a plurality ofgrid lines and a plurality of data lines, and the grid lines and the data lines intersect to define a plurality of pixel regions; the pixel region comprises a pixel driving circuit; the pixel drivingcircuit comprises a driving transistor and at least one first node transistor electrically connected with a first node; in the direction perpendicular to the plane where the substrate is located, anoverlapped area between an active layer of the first node transistor and a grid electrode of the first node transistor is a channel of the first node transistor, at least one blocking unit is arrangedin the side, far away from the substrate, of a first metal layer, and at least part of the channel of the at least one first node transistor is covered by a blocking unit. According to the invention,at least part of the region of the channel of the at least one first node transistor is covered by the blocking unit, so that the leakage current of the first node transistor is reduced, and a screenshaking phenomenon is overcome.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to an OLED array substrate, a display panel and a display device. Background technique [0002] In recent years, the Organic Light Emitting Display (OLED) panel has become a very popular emerging flat panel display industry at home and abroad. It has self-illumination, high brightness, wide viewing angle, fast response, high contrast, wide color gamut, Low energy consumption, thin panels, rich colors, flexible display, wide operating temperature range and many other excellent features, so it is known as the next generation of "star" flat panel display technology. OLED can meet the requirements of higher performance and greater information capacity of displays in today's information age. [0003] However, in the prior art, when the organic light-emitting display panel is always in the display mode, there will be a phenomenon of shaking the screen. Contents of the...
