  • Publication number: 20240078960
    Abstract: A display device is disclosed. The display device allows a difference value between terminal voltages of light-emitting devices on two adjacent rows of a display substrate to be less than a target difference value by reversing a position of a power supply input terminal of one of power supply signal lines from a position adjacent to a printed circuit board to a position away from the printed circuit board, thereby correspondingly reducing a difference value between currents. Therefore, a brightness difference between the light-emitting devices of each row can be reduced to an extent that cannot be easily recognized by human eyes, thereby improving display quality of the display device.

  • Patent number: 11474401
    Abstract: A display panel and a fabrication method thereof, and a display apparatus are provided. The display panel includes: a base substrate, and a display region and a non-display region on the base substrate. The display region has a special shaped boundary, and includes: a plurality of display pixels and transition pixels; the transition pixels are provided between the display pixels and the special-shaped boundary; each of the display pixels and each of the transition pixels respectively include: a first electrode and a second electrode. An area of each of the first electrodes of the transition pixels is different from an area of each of the first electrodes of the display pixels; and/or, an area of each of the second electrodes of the transition pixels is different from an area of each of the second electrodes of the display pixel.
