AI Technical Summary

Technical Problem

In large display panels, as pixel units increase, the number and occupancy area of ​​pixel compensation circuits also increase significantly, making it difficult to realize a compact display panel.

Method used

The method of connecting multiple light emitting units per set of pixel compensation circuit is adopted. Each set of pixel compensation circuit is connected to M light emitting units and is driven through M light emitting control signal ports, reducing the required number of signal ports and area occupied.

Benefits of technology

It effectively reduces the number and area of ​​pixel compensation circuits, realizes a more compact display panel design, and improves the screen resolution of the display panel.

Abstract

To provide a pixel circuit and a driving method therefor, and a display device (800).SOLUTION: A pixel circuit comprises a plurality of pixel compensation circuits (011). Each pixel compensation circuit (011) can be connected to M light-emitting units (021) of the same column, that is, one pixel compensation circuit (011) can be used for driving M light-emitting units (021), thereby reducing the number of the pixel compensation circuits (011) that are required to be configured. Furthermore, each M light-emitting control signal end (EM) included in each group of light-emitting control signal ends (03) can be connected to one group of pixel compensation circuits (011)(that is, K rows of pixel compensation circuits (011)), thereby reducing the number of signal ends that are required to be configured and further reducing the area of the pixel circuit occupying a circuit board to be more advantageous to realize a narrow-bezel display panel.SELECTED DRAWING: Figure 1
