Abstract: A spliced screen and a display terminal are disclosed. In the spliced screen, a structural component is disposed on two adjacent display panels and covers a splicing gap between the two adjacent display panels. A lamp plate is disposed on a surface of the structural component. When the spliced screen displays an image, a plurality of luminescent bodies disposed on the lamp plate close to the display panels also emit light, thereby preventing black strips from appearing on the image. In the spliced screen, a viewing angle of the display panels and a viewing angle of the lamp plate are same, so that a brightness of the display panels and a brightness of the lamp plates are same when the spliced screen is viewed from a lateral side. As such, display quality is improved.

Abstract: According to an embodiment of the present disclosure, a display screen, a display device, and a method for manufacturing the display screen are disclosed. The display screen includes a display panel and a light bar. The light bar includes an array substrate and a plurality of light emitting elements, and a first gap is provided between two adjacent light emitting elements. A reflecting wall is arranged in the first gap between at least two adjacent light emitting elements. By arranging the reflecting wall, the side light of the light emitting elements can be reflected upwards, thereby reducing an emission angle of the light bar.

Abstract: A manufacturing method of a display device, the display device, and a spliced display device are disclosed. The display device includes a liquid crystal display panel (LCD display panel), a plurality of pad units, a plurality of conductive units, and a plurality of mini light-emitting diodes (mini-LEDs). The mini-LEDs are manufactured in a bezel area of the LCD display panel to allow the bezel area of the LCD display panel which does not emit light and display originally to display by the mini-LEDs, thereby improving a screen ratio of the display device and improving product competitiveness of the spliced display device.

Abstract: The present invention provides a substrate and a method for monitoring positions of boundaries of a film layer disposed on a substrate. A plurality of sets of positioning units are provided in a non-display region of the substrate. Each set of the positioning units includes at least two primary positioning marks and corresponding primary positioning rulers. There are at least two secondary positioning marks and corresponding secondary positioning rulers disposed between the two adjacent primary positioning marks. The present invention determines a specific position of the boundaries of the film layer according to readings of the positioning rulers of the plurality of sets of positioning units corresponding to the boundaries of the film layer.
