AI Technical Summary

Technical Problem

In existing technologies, as pixel structures become more complex, the number of GOA circuits increases, making it impossible to achieve an extremely narrow bezel design.

Method used

A display driving circuit is provided, which includes multiple sets of shift circuits, each set including multiple cascaded shift register units. At least two shift register units connected to the same pixel in at least two sets of shift circuits share the same cascade unit and output different display driving signals through different output units.

Benefits of technology

It enables reliable output of multiple display driving signals in pixels with complex structures, while reducing the bezel area and supporting narrow bezel designs.

Abstract

The application discloses a display driving circuit, a display substrate and a display device, and belongs to the technical field of display. The display driving circuit comprises multiple groups of shift circuits (00) for outputting multiple display driving signals of different types, and each group of shift circuits (00) comprises multiple shift register units (01) connected in cascade. At least two shift register units (01) connected with the same pixel in at least two groups of shift circuits (00) can share the same stage transmission unit (011) and output different display driving signals through different output units (012), so that the display driving circuit can not only reliably output multiple display driving signals to drive the pixels of a complex structure to emit light, but also occupies less frame area, and can better facilitate the narrow frame design.
