  • Patent number: 12322341
    Abstract: A display substrate and a display device are disclosed. The display substrate includes a base substrate and a plurality of sub-pixels located thereon. Each sub-pixel includes a pixel circuit and a pixel electrode electrically connected thereto, and each pixel circuit includes a driving sub-circuit. The pixel electrode includes a main electrode part and a first electrode extension part extending therefrom. The display substrate includes first type of sub-pixels. The main electrode part of each sub-pixel of the first type of sub-pixels is not overlapped with a control electrode of the driving sub-circuit of the sub-pixel or an electrode part directly electrically connected to the control electrode, and the first electrode extension part of each pixel electrode is at least partially overlapped with the control electrode or the electrode part. The first type of sub-pixels include at least two sub-pixels configured to emit light of different colors.
    Type: Grant

  • Patent number: 11972727
    Abstract: A display substrate (20) and a display device (40). The display substrate (20) comprises a base substrate and a plurality of sub-pixels (100) located on the base substrate. Each sub-pixel (100) comprises a pixel circuit and a pixel electrode (134) electrically connected to the pixel circuit, and each pixel circuit comprises a driving sub-circuit. The pixel electrodes (134) each comprises an electrode body part (140) and a first electrode extension part (142) extending from the electrode body part (140). The display substrate (20) comprises first-type sub-pixels. The electrode body part (140) of each first-type sub-pixel (100) does not overlap a control electrode of the driving sub-circuit of the sub-pixel or an electrode part directly electrically connected to the control electrode, and the first electrode extension part (142) of each pixel electrode (134) at least partially overlaps the control electrode or the electrode part.
