Description

Liquid crystal module and liquid crystal display device

Technical Field

Background

Along with the improvement of living standard, the higher the consumer demand on the product modeling, the narrower the frame of the current liquid crystal display device such as a liquid crystal television and the like, and in order to meet the demand of the ultra-narrow frame of the product, the width of a BM area (black area around a visible area) on four sides of a liquid crystal glass panel O/C is also smaller, and the current BM=3.5 mm,0.99mm and even the extreme BM=0.5 mm are developed from the previous BM=5-8 mm. It is easy to understand that the smaller the BM is, the smaller the non-display area can be made and the higher the viewing experience when the very narrow bezel O/C is applied to a tiled screen product. However, the width of the BM region directly affects the fixation of the liquid crystal glass, and the smaller the BM, the greater the fixation difficulty. This presents new challenges for the design of liquid crystal module solutions.

For products with the width of 5-8 mm of common BM, LCD fully-adhered double-sided foam rubber is applied in industry, the common width is more than or equal to 3mm, the thickness is more than or equal to 0.86mm, but the extremely narrow BM 0.9O/C adhesive tape adhesive width is only 0.9mm, the adhesive tape adhesive strength with the width of about 1mm cannot meet the test standard and the product reliability requirement, die cutting and forming are difficult, and a production line cannot be constructed, so that the traditional foam rubber cannot meet the product requirement; so for the O/C bonding with BM width smaller than 0.9mm, the current industry adopts UV glue for fixation.

Because the liquid crystal display product inevitably faces reworking production problems at the production end, the reworking scheme of the traditional LCD fully-attached double-sided foam rubber can adopt a sheet with 0.2-0.4mm to cut the PU layer of the foam rubber, so that the liquid crystal glass panel is separated from the middle frame, and the liquid crystal glass panel is taken out for returning to the working industry; but extremely narrow BM adopts liquid UV colloid to fix, and liquid UV colloid is at 0.1-0.3mm (the thickness of dispensing is controlled at 0.4-0.6 mm) after UV baking pressure maintaining and the joint strength is high, and the liquid crystal glass panel is easy to produce breakage and damage when demolishing, so that the problem of difficult reworking exists in the liquid crystal module fixed by using UV glue, the reject ratio is as high as 95%, and the product cost is increased sharply indirectly.
