Abstract
The utility model discloses a kind of liquid crystal screen back plate, including the metallic plate on rear side of liquid crystal display, the metallic plate includes zinc-plated substrate, and the zinc-plated substrate upper back roller coat has top coat layer, the zinc-plated substrate back lower is provided with circuit board and face-piece, and the face-piece is located at outside circuit board.This backboard has enough intensity and hardness, by dividing roller coat top coat layer in substrate upper back, vacate the thickness of back lower point, to be provided with circuit board and face-piece in back lower point, so as to substitute traditional liquid crystal screen center and the plastics face-piece on top, equivalent to by traditional liquid crystal screen backboard, the center of lower part and the plastic cover on top are shell integrated, while complex production process degree is reduced, considerably reduce the thickness of whole liquid crystal display, so that the thickness of whole liquid crystal display thinnest part is reduced within 10mm by 30 original~40mm, material can also be saved, lift product specification.
Description
Technical field
It the utility model is related to LCD TV and liquid crystal display part field, more particularly to a kind of liquid crystal screen back plate.
Background technology
At present, common liquid crystals TV and liquid crystal display dorsal shield are made of two parts mostly, and internal layer is metallic plate punching
Molding center, outer layer are plastics face-piece.Liquid crystal panel and circuit board are separately mounted to the inner side and outer side of center, plastics face-piece
Circuit board is wrapped up, is shielded.As liquid crystal display is to development is thinned, in order to pursue the ultra-thin effect of vision, gradually
The original various circuit boards at random for being distributed in the whole center back side are focused on into bottom, the liquid crystal display thickness base of no circuit board section
Originally it is equal to the thickness that liquid crystal panel adds center and plastics face-piece, but this does not still meet consumer and urgent is essential to ultra-thin
Will.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of simple production process and the ultra-thin back of the body
Plate.
Technical solution is used by the utility model solves its technical problem：
A kind of liquid crystal screen back plate, including the metallic plate on rear side of liquid crystal display, the metallic plate include zinc-plated substrate, institute
Stating zinc-plated substrate upper back roller coat has top coat layer, and the zinc-plated substrate back lower is provided with circuit board and face-piece, the face
Clamshell is located at outside circuit board.
As the improvement of above-mentioned technical proposal, the zinc-plated substrate back lower also roller coat has resistance and fingerprint resistance coating, described resistance to
Fingerprint coating thickness is 1~10 μm.
As the improvement of above-mentioned technical proposal, the zinc-plated substrate front offset roll scribbles anti-corrosion back of the body enamelled coating, the anti-corrosion back of the body paint
Layer thickness is 3~15 μm.
As the improvement of above-mentioned technical proposal, the zinc-plated substrate thickness is 0.5~1.5mm.
As the improvement of above-mentioned technical proposal, the finishing coat layer thickness is 15~50 μm.
The beneficial effects of the utility model have：
This backboard has enough intensity and hardness, by dividing roller coat top coat layer in substrate upper back, vacates under rear side
Partial thickness, point to be provided with circuit board and face-piece in back lower, so as to substitute traditional liquid crystal screen center and top
Plastics face-piece, it is shell integrated equivalent to by the plastic cover of the center of traditional liquid crystal screen backboard upper and lower part and top, produced reducing
While complex process degree, considerably reduce the thickness of whole liquid crystal display so that the thickness of whole liquid crystal display thinnest part by
30~40mm originally is reduced within 10mm, moreover it is possible to is saved material, is lifted product specification.
Brief description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the diagrammatic cross-section of metallic plate in the utility model embodiment.
Embodiment
Referring to Fig. 1, a kind of liquid crystal screen back plate of the utility model, including the metallic plate on rear side of liquid crystal display, it is described
Metallic plate includes zinc-plated substrate 1, and the zinc-plated 1 upper back roller coat of substrate has top coat layer 2, shields.
In addition, 1 back lower of zinc-plated substrate also roller coat has a resistance and fingerprint resistance coating 3, resistance and fingerprint resistance coating 3 also have anti-corrosion and
Conductive performance, metallic plate, which is located at resistance and fingerprint resistance coating 3, is provided with circuit board and face-piece, and the face-piece is located at outside circuit board,
Circuit board is wrapped up, is shielded, face-piece uses punch forming, reduces complex process degree, zinc-plated 1 front offset roll of substrate
Anti-corrosion back of the body enamelled coating 4 is scribbled, with reference to resistance and fingerprint resistance coating 3, can make metallic plate that there is more preferable anticorrosion effect.
Specifically, 1 thickness of zinc-plated substrate is 0.5~1.5mm, and 2 thickness of top coat layer is 15~50 μm, described resistance to
3 thickness of fingerprint coating is 1~10 μm, and 4 thickness of the anti-corrosion back of the body enamelled coating is 3~15 μm.
Relative to the center of traditional liquid crystal screen and the plastics face-piece on top, metallic plate in this liquid crystal screen back plate will be equivalent to will
The center and plastic cover of traditional liquid crystal screen backboard upper and lower part are shell integrated, while complex production process degree is reduced, significantly
Ground reduces the thickness of whole liquid crystal display so that the thickness of whole liquid crystal display thinnest part is reduced to 10mm by 30 original~40mm
Within, if individually only that the center on traditional liquid crystal screen backboard top and plastic cover is shell integrated, and lower part redesign center and modeling
Charge level shell is with protection circuit plates, although so also reducing liquid crystal display thickness, can increase complex process degree, thus this product
Design it is more economical, moreover it is possible to save material, metal appearance can more lift product specification.
The better embodiment of the above, simply the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as it reaches the technique effect of the utility model with any same or similar means, should all belong to the utility model
Protection domain.
