AI Technical Summary

Technical Problem

When existing OLED display products integrate gate driving circuits, the space in the display area affects the resolution, making it difficult to compatible with high resolution and special-shaped display requirements.

Method used

Multiple sub-pixels are divided into multiple groups, each group of sub-pixels shares a light emitting control sub-circuit, and through optimized layout design, the number of light emitting control signal lines and power lines is reduced, and a 5T1C circuit structure is adopted to achieve efficient transmission of driving signals.

Benefits of technology

The layout space of sub-pixels is optimized, compatible with high-resolution display, supports the high-resolution requirements of special-shaped display products, and simplifies the production process and reduces costs.

Abstract

The invention provides a display substrate and a display device. The display substrate comprises a substrate body and a plurality of sub-pixels arranged on the substrate body, and the sub-pixels are distributed in an array mode. The sub-pixel comprises a sub-pixel driving circuit and a light-emitting element, and the sub-pixel driving circuit comprises a driving sub-circuit and a light-emitting control sub-circuit which are coupled with each other; the light-emitting element comprises an anode pattern; the plurality of sub-pixels are divided into a plurality of groups of sub-pixels, each group of sub-pixels comprises two sub-pixels arranged along a first direction, and two sub-pixel driving circuits included in the two sub-pixels multiplex the same light-emitting control sub-circuit. The light-emitting control sub-circuit is used for respectively controlling the driving sub-circuits in the two sub-pixels to write driving signals into the anode pattern; the sub-pixel further includes a data line including a portion extending in the first direction.
