Abstract

The embodiment of the present application discloses a spliced ​​lamp board and a display device, including a first LED lamp board and a second LED lamp board; the first LED lamp board is provided with a first signal input terminal, and the first LED lamp board One end is close to the first signal input terminal, and the second end of the first LED light board is far away from the first signal input terminal; the second LED light board is provided with a second signal input terminal, and the second end of the second LED light board is One end is close to the second signal input terminal, the second end of the second LED light board is far away from the second signal input terminal; the first end of the first LED light board is connected to the first end of the second LED light board or The second end of the first LED lamp board is docked with the second end of the second LED lamp board. In this application, by connecting the brightest or darkest ends of the two LED lamp boards, it is possible to avoid brightness jumps at the splicing joints of the spliced ​​lamp boards.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a spliced ​​lamp panel and a display device. Background technique [0002] As the high-end TV market has higher and higher requirements for image quality, improving display image quality has become a new demand for high-end TVs. At present, 8K OLED (Organic Light-Emitting Diode, organic light-emitting diode) is limited by problems such as compensation circuit, backplane technology and driver design, and still needs to be developed. As a new display technology, Mini LED (Mini Light Emitted Diode) has obvious advantages over OLED in terms of brightness and power consumption. [0003] However, since the Mini LED backplane currently only supports small sizes, when it is used as a backlight for a large-size TV (75 inches, etc.), it often requires multiple LED light panels to be spliced ​​into a large size. However, spliced ​​large-size panels will have brightness jumps re...
