Problems solved by technology

However, due to the limitation of massive transfer machines, Micro-LED large-screen display can only be realized by splicing
Since the pixel pitch of the Micro-LED display is very small, the total error allowed during splicing is very small, otherwise it is difficult to achieve seamless splicing display
The current Micro-LED large-screen display technology has serious seam problems due to the processing error of the splicing mechanism and the lack of a seam adjustment mechanism, and even causes the Micro-LED display units to collide and damage each other during splicing.

Abstract

The invention discloses a splicing display device and a manufacturing method thereof. The splicing display device comprises a splicing mechanism, a plurality of display units and a plurality of connecting mechanisms. The splicing mechanism is provided with a plurality of splicing areas which are adjacent to one another; a limiting through hole penetrating through the splicing mechanism is formed in each splicing area; the plurality of display units are spliced on the splicing mechanism and are in one-to-one correspondence with the plurality of splicing areas; the plurality of connecting mechanisms and the plurality of display units are arranged in a one-to-one correspondence manner; the connecting mechanism comprises a first connecting piece and a second connecting piece; the first connecting pieces are fixedly connected to the sides, close to the splicing mechanism, of the corresponding display units and located in the corresponding limiting through holes. The second connecting piece is located on the side, away from the display unit, of the first connecting piece, detachably connected with the first connecting piece in an adsorption mode and movably connected with the splicing mechanism. The problem that the display units are damaged due to strong adjustment of the abutted seams or the adjacent display units are damaged due to mutual collision can be avoided, and seamless splicing can be achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a spliced ​​display device and a manufacturing method thereof. Background technique [0002] Micro-LED refers to a technology that uses a micron-scale LED (light emitting diode, light emitting diode) as a light-emitting pixel unit and assembles it with a driving module to form a high-density display array. Compared with LCD (Liquid Crystal Display, liquid crystal display), OLED (Organic Light-Emitting Diode, organic light-emitting diode) and other display technologies, Micro-LED has advantages in brightness, resolution, energy consumption, service life, response speed and thermal stability. It has cross-generational advantages and is an internationally recognized future display technology. [0003] At present, the large-screen display market is very large, such as shopping mall advertisements, center consoles, meeting rooms, gymnasiums, etc. There are mainly four des...
