Problems solved by technology

Since the liquid crystal display panel needs to use frame glue to seal the liquid crystal in a specific area, and the frame glue part cannot be used for display, so when using the liquid crystal display panel to make a spliced ​​display device, there is often a gap between the display areas of adjacent display panels. The wide non-display area leads to obvious seams in the splicing display device, which will destroy the continuity of the display screen and greatly affect the display effect

Abstract

The invention discloses a display module, a display device and a spliced screen, and relates to the technical field of display. The display module comprises at least two main display areas and a spliced display area, and at least part of the spliced display area is located between adjacent two main display areas in the direction parallel to the light-emitting surface of the display module; in therange of the spliced display area, the display module comprises a first display panel in the direction perpendicular to the light-emitting surface of the display module, the first display panel comprises a first substrate, a driving circuit and a plurality of light-emitting devices, the driving circuit and the light-emitting devices are arranged on the first substrate, and the driving circuit is used for driving the light-emitting devices to emit light. By filling at least part of the first display panel between the adjacent two main display areas, the area between the two main display areas has a display function, splicing seams between the main display areas can be weakened or eliminated, and therefore module display of any size is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display module, a display device and a splicing screen. Background technique [0002] With the development of flat panel display technology, major manufacturers have launched larger-sized display panels one after another. Due to the limitation of production technology, when the size of the display panel cannot be made larger, a spliced ​​display device emerges as the times require. The splicing display device has a large-scene display effect and can bring users an immersive visual experience, so it is widely used in advertising display, publicity, exhibitions and other occasions. [0003] Currently, large-screen splicing display devices are mostly formed by splicing liquid crystal (Liquid Crystal Display, LCD) display panels. Since the liquid crystal display panel needs to use the frame glue to seal the liquid crystal in a specific area, and the frame glue pa...
