Abstract

The embodiment of the invention discloses a flexible splicing module, a display device and a preparation method of the flexible splicing module. In one specific implementation mode, the flexible splicing module comprises a flexible circuit board and a plurality of flexible display modules, and each flexible display module comprises a flexible substrate, a flexible display panel arranged on the flexible substrate and a first packaging layer for packaging the side face of a display area of the flexible display panel. The first packaging layers of the adjacent flexible display modules are spliced in an attached mode, a bonding electrode is arranged on the side, opposite to the flexible display panel, of the flexible substrate, the bonding electrode is electrically connected with the flexible display panel through a through hole formed in the flexible substrate, and the bonding electrode is bonded to the flexible circuit board. The flexible splicing module provided by the embodiment of the invention can realize seamless display and seamless packaging at the splicing part of the adjacent flexible display modules, and has the characteristics of narrow frame and seamless splicing.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a flexible splicing module, a display device and a preparation method thereof. Background technique [0002] At present, large-scale and multi-morphology are the two major development directions of displays. Nowadays, the size of mainstream display devices has grown from 20 inches to 40 inches, 65 inches and 85 inches, and people's demand for large-size display devices is constantly increasing. For large-size OLED display devices, compared with small-size display devices, the yield rate is doubled, and there are many problems such as transportation and installation. Therefore, projection technology has always been the mainstream in the field of ultra-large-size display technology. [0003] The splicing display device can solve the above problems, however, how to reduce the splicing gap between the splicing screens of the splicing display device is a technical p...
