Display panel and display device

By setting a gating unit for partition refresh signal control in the display panel, vertical partition refresh of the thin-film transistor liquid crystal display panel is realized, which solves the problem that the existing technology cannot meet the refresh rate of different partitions, and improves the display effect and stability.

AI Technical Summary

Technical Problem

Existing thin-film transistor liquid crystal display panels cannot achieve vertical partition refresh, and cannot meet the display requirements of different partitions and different refresh rates of integrated display devices for vehicle instruments, central control and passenger entertainment.

Method used

By setting a first sub-display area and a second sub-display area arranged along the pixel row direction in the display panel, and setting a gating unit between the shift register unit and the first sub-display area, the output of the gate drive signal is controlled by a preset partition refresh signal to achieve the refresh or hold of the first sub-display area and the continuous refresh of the second sub-display area.

Benefits of technology

It enables vertical partitioned refresh of the display device, meeting the different refresh rate requirements of different areas, and improving the display effect and stability of the display device.

Abstract

The display panel and the display device are provided. The display device comprises a display area including a plurality of sub-display areas, the plurality of sub-display areas including first sub-display areas and second sub-display areas arranged along a pixel row direction; a plurality of shift register units for providing gate driving signals to the first sub-display areas and the second sub-display areas; and a plurality of first gating units arranged between the plurality of shift register units and the first sub-display areas, for outputting or not outputting the gate driving signals to the first sub-display areas according to a preset first partition refresh signal, so that partition refresh is realized in the first sub-display areas and the second sub-display areas, and longitudinal partition refresh of the display device is realized.
