Description
[technical field]
The utility model relates to a kind of liquid crystal indicator, particularly a kind of liquid crystal indicator easy to assembly.
[background technology]
The liquid crystal indicator of prior art uses module backlight as light source, and in module backlight, often uses shading rubber belt to cover the fixedly blooming piece of shading rubber belt below of stickiness that module backlight edge prevents light leak and utilize shading rubber belt.
The structure of a kind of liquid crystal indicator 10 of prior art as shown in Figure 1, it comprises liquid crystal panel 11 and module backlight 12, this module 12 backlight is positioned under this liquid crystal panel 11.This module 12 backlight is provided with shading rubber belt 13, brightening piece 14, area source 15, reflector plate 18 and framework 19 from top to down in regular turn, and this area source 15 comprises light guide plate 16 and light emitting diode 17.This shading rubber belt 13 is covered on the adjacent edge of this brightening piece 14 and this framework 19, covers the light leak at this edge.
Yet, the liquid crystal indicator of prior art is strong and have flexible because of the shading rubber belt stickiness, need careful when pasting, when shading rubber belt affixes framework or blooming piece, be not easy to be stripped from and damage easily blooming piece and produce cull, so it is inconvenient to cause site work person to assemble when shading rubber belt pastes.And this shading rubber belt is unfavorable for secondary or heavy industry repeatedly, because this shading rubber belt stickiness is forced to such an extent that peel off difficultly, also is easy to generate cull during heavy industry, causes product assembly failure rate to increase.In addition, liquid crystal indicator is when doing fiduciary level high ambient temperature high humidity project testing, the viscose of shading rubber belt is subject to hot and humid condition effect and rotten warpage, and the related blooming piece warpage that pastes under the shading rubber belt that influences causes display frame to produce ripple (Waving) phenomenon.
[utility model content]
In order to solve the inconvenient problem of liquid crystal indicator assembling of the prior art, be necessary to provide a kind of liquid crystal indicator easy to assembly.
The disclosed a kind of liquid crystal indicator of one preferred embodiment comprises a liquid crystal panel and a module backlight.This module backlight comprises a shading element, an area source and a framework.This area source, this shading element and this liquid crystal panel are successively set in this framework; The side of this shading element has projection, and the side of this framework has notch and cooperates with this projection.
Compared to prior art, the shading element of this liquid crystal indicator has projection, and having notch on the framework cooperates with this projection, because it is fixing that the shading element of this liquid crystal indicator utilizes its projection to cooperate with the notch of this framework, but not utilize viscose glue to fix, make this shading element simple and convenient when assembling, and can not damage blooming piece because of viscose or produce cull.

[embodiment]
See also Fig. 2 and Fig. 3, Fig. 2 is the perspective exploded view of a kind of liquid crystal indicator 20 of the utility model first embodiment exposure, and Fig. 3 is the local horizontal sectional view that the disclosed shading element of first embodiment cooperates with framework.This liquid crystal indicator 20 is provided with housing 226, a liquid crystal panel 21 and a module 22 backlight from top to down in regular turn.Wherein, this module 22 backlight is provided with shading element 222, brightening piece 224, diffusion sheet 227, area source 223, reflector plate 225 and framework 221 from top to down in regular turn.This area source 223 comprises light-emitting component 231 and light guide plate 232, and this light-emitting component 231 is arranged on the side of this light guide plate 232, and it comprises a plurality of light emitting diodes 233.The relative both sides of this shading element 222 have a projection 220 respectively, and the side of this framework 221 has two notches 210 and cooperates with this two projection 220 respectively, and this two projection 220 is all square with the horizontal section of this two groove 210.This groove 210 is a through hole, and this square protrusion 220 is arranged in this notch 210.
Above-mentioned shading element 222 is a non-tacky elastic material, its material can be polyvinyl ester or polycarbonate, as polyethylene terephthalate (PolyethyleneTerephthalate, PET), rely on the elastic bending of this shading element 222 conveniently its projection 220 to be inserted in the notch 210, make this liquid crystal indicator easy to assembly.
See also Fig. 4, the local horizontal sectional view that cooperates with framework for the disclosed shading element of the utility model second embodiment.This embodiment and the first embodiment difference are that the horizontal section of the projection 320 of this embodiment is semicircle, and the horizontal section of this notch 310 is semicircle, and this notch 310 is a blind hole.This half-circle projection 320 helps inserting fast in this groove 310 when assembling, makes easy to assembly.
Compared to prior art, the shading element 222 of this liquid crystal indicator 20 has projection 220, and having notch 210 on the framework 221 cooperates with this projection 220, because it is fixing that the shading element 222 of this liquid crystal indicator 20 utilizes the projection 220 of this shading element 222 to cooperate with the notch 210 of this framework 221, but not utilize viscose glue to fix, make this shading element 222 when assembling, can not damage blooming piece or generation cull, so easy to assembly because of viscose.And when heavy industry, shading element 222 dresses are got conveniently, and do not introduce cull, and heavy industry speed and yield are improved.Also have, liquid crystal indicator 20 owing to there is not the existence of viscose, has also solved the problem of the blooming piece warpage that is caused by viscose simultaneously when doing fiduciary level high ambient temperature high humidity project testing.
Above-mentioned projection 220 is not limited to two with the combination of notch 210, also can be for one or more.
The distribution of above-mentioned projection 220 is not limited to relative both sides, also can be adjacent both sides, three sides or four sides.
The combination of above-mentioned projection 220 and notch 210 can also be joined semicircle through hole for fill a prescription shape blind hole or through hole, square protrusion prescription shape blind hole or half-circle projection of half-circle projection.
Above-mentioned notch 210 can also be the through hole or the blind hole of other shape ease of assembly.
Above-mentioned light-emitting component 231 can also be cold cathode ray tube.
