Abstract

The invention provides a display substrate and a manufacturing method thereof and a display device, relates to the technical field of display, and aims to solve the problem that screen flickering of adisplay occurs due to inconsistent time for anode voltage in sub-pixels of different colors to reach stability. In the display substrate, each sub-pixel comprises a power supply signal line, a sub-pixel driving circuit and a shielding pattern; the sub-pixel driving circuit comprises a driving transistor and a compensation transistor with a double-gate structure; the shielding pattern is electrically connected with the power signal lines in the adjacent sub-pixels in the second direction, and an overlapping area exists between the orthographic projection of the shielding pattern on the substrate and the orthographic projection of the conductor pattern in the compensation transistor on the substrate; the display substrate comprises a plurality of first sub-pixels and a plurality of second sub-pixels, and the overlapping area in the first sub-pixels is larger than that in the second sub-pixels. The display substrate provided by the invention is used for displaying.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Active Matrix Organic Light-Emitting Diode (English: Active Matrix Organic Light-Emitting Diode, referred to as: AMOLED,) display, compared with the traditional liquid crystal display, has the advantages of self-illumination, wide color gamut, high contrast, light and thin, etc., and has been widely used in recent years. Applied in various fields. [0003] The AMOLED display includes a sub-pixel driving circuit, and the gate voltage of the driving transistor in the sub-pixel driving circuit is easily interfered by other transistors, and is in an unstable state during the light-emitting phase. The instability of the gate voltage of the drive transistor will cause the anode voltage of the light-emitting element to change, so that the anode voltage of the light-emitting element...
