Publication number: 20250046231Abstract: A spliced display screen and a spliced display device are provided. The spliced display screen includes gate driving units arranged within pixel units to drive these pixel units, eliminating the need for binding scan chips. This approach can reduce the number of side wirings and binding terminals, thereby improving the yield of the spliced display screen. Additionally, by placing both scan terminals and data terminals on the same side of the display area, the display panel is designed with connecting terminals on only one side, effectively eliminating a border on one side of a display panel. Moreover, a terminal area of one display panel is arranged corresponding to the display area of another display panel, and therefore, a splicing seam is minimized or even eliminated.Type: ApplicationFiled: December 3, 2023Publication date: February 6, 2025Inventors: Zhuhui LI, Yanfen LI
