Patent number: 12387656Abstract: 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.Type: GrantFiled: February 26, 2021Date of Patent: August 12, 2025Assignee: TCL China Star Optoelectronics Technology Co., Ltd.Inventor: Zhaoke Zhang
