  • Patent number: 12253775
    Abstract: A display panel and display apparatus, display panel includes an array substrate. Array substrate includes substrate and has display region. Display region includes color filter, pixel electrode, and first transistor that are located on same side of substrate. First transistor includes first semiconductor layer. Along direction perpendicular to plane of substrate, color filter is located between first semiconductor layer and pixel electrode, and first semiconductor layer is electrically connected to pixel electrode through first connecting portion. First connecting portion includes first connecting sub-portion in first connecting hole. Orthographic projection of first connecting sub-portion on plane of substrate does not overlap with orthographic projection of color filter on plane of substrate. Along direction parallel to plane of substrate, first connecting sub-portion at least partially overlaps with color filter.

  • Publication number: 20240404484
    Abstract: A display panel and a display apparatus, in the display panel, a pixel unit includes a plurality of sub-pixels, the sub-pixels in a same pixel unit are electrically connected to a same scan line and are each electrically connected to different data lines/the display panel further includes demultiplexers, each demultiplexer includes two output terminals connected to different data lines, and is configured to transmit data signals to different data lines. The plurality of sub-pixels of the same pixel unit include at least three sub-pixels with different colors. Accordingly, the pixel units need not to borrow sub-pixels from each other while achieving full-color display of the display panel, which is conducive to improving the stability of display quality, using 1:2 demultiplexers to transmit data signals to sub-pixels ensures that each sub-pixel has sufficient charging time, thereby being conducive to ensuring the display quality of the display panel.
