Spliced screen and preparation process thereof

Abstract

The invention discloses a spliced screen and a preparation process thereof, and relates to the technical field of display, the preparation process comprises the steps of obtaining liquid crystal glass and an optical module, positioning a light blocking area, arranging a light blocking part, integrally assembling and arranging a protection part, and the process principle is that the light leakage prevention effect of a liquid crystal display unit is achieved by arranging the light blocking part and the protection part; the scheme that light leakage is prevented through shading glue in the prior art is avoided, the light blocking part and the protection part are simple in structure, production equipment and a curing waiting process do not need to be additionally added, therefore, the production technological process of the whole spliced screen is not excessively increased, and operation is easy during maintenance and breakdown maintenance and disassembly.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a splicing screen and a preparation process thereof. Background technique [0002] The splicing screen is a complete LCD splicing display unit, which can be used as a display alone or can be used to form a super large screen through splicing. According to different usage requirements, it can realize single-screen split display, single-screen independent display, arbitrary combination display, full-screen LCD splicing, vertical screen display, and the image frame can be compensated or covered. [0003] As far as the current market is concerned, thin, ultra-narrow bezels are the mainstream form of the current splicing screen market. In the design of the splicing screen LCD panel, since the adjacent sides of the liquid crystal glass are provided with COF (chip-on-film) flexible circuit boards, the upper and lower glass substrates sandwiching the liquid crystal glass, the upper gla...

Problems solved by technology

[0004] At present, splicing screen manufacturers mainly inject an appropriate amount of light-shielding glue into the cavity formed between the frame edge and the liquid crystal glass to avoid light leakage, but in the production process, the assembled splicing screen needs to be placed horizontally to let the glue cure. Not only does it need to consume enough workshop space and production time, which increases the production cost, but also requires the purchase of additional gluing machine equipment for production, which is expensive

Secondly, this method cannot completely solve the problem of light leakage. After the light-shielding glue is cured, observe the gap between the frame wrapping and the screen from the front of the display unit at 45°, and you can still see a pixel red line between the frame and the screen.
