Description
Technical field
The present invention relates to field of liquid crystal display, in particular, relate to a kind of liquid crystal indicator.
Background technology
Liquid crystal indicator generally comprises backboard, center and preceding frame; The optical module of the fixing module backlight of backboard support, and preceding frame is around the edge of liquid crystal panel, center is between preceding frame and backboard; The liquid crystal panel of having separated optical module, and frame immobile liquid crystal panel before cooperating.As shown in Figure 1; Have a kind of liquid crystal indicator that does not have the center design now, directly the cooperation with backboard 300 and preceding frame 200 realizes the fixing of optical module and liquid crystal panel, when adopting no center to design; Because the side of optical module 600 is provided with light source assembly 400 (like LED); There is stronger light in the light source assembly top, can enter into liquid crystal panel from the side of liquid crystal panel 100, and liquid crystal panel can produce focus (hotspot) phenomenon; And form bright dizzyly at effective edge of display area, cause the decline of display effect.
Summary of the invention
Technical matters to be solved by this invention provides a kind of liquid crystal indicator of avoiding liquid crystal panel to produce hot spot phenomenon.
The objective of the invention is to realize through following technical scheme:
A kind of liquid crystal indicator; Comprise preceding frame, with the fixing backboard of preceding frame; Clamping has optical module between said preceding frame and the backboard; And the liquid crystal panel that is positioned at the optical module exiting surface, the sidepiece incidence surface correspondence of said optical module is provided with light source, is provided with between said light source and the liquid crystal panel to intercept light directly gets into liquid crystal panel inside from light source shading member.
Preferably, said liquid crystal panel edge extends said optical module exiting surface scope, and one side corresponding at light source forms extension, and said shading member is fixed on the extension of panel.This is a kind of light-shielding structure of panel side, and it is inner that the light part that light source sends directly gets into liquid crystal panel from extension, and another part can be through the reflection of preceding frame and backboard; From other direction directive extensions, and the shading member directly is fixed on the extension, can the position of the easy light leak of extension be covered; So no matter light from which direction is come; All can't inject extension, compare the light-shielding structure of light source side, shaded effect is better; Further avoid liquid crystal panel to produce hot spot phenomenon, improve display quality.
Preferably, said shading member is a shading rubber belt.Shading rubber belt is easy to use, and versatility is good, can be applicable to the panel of various difformities, size.
Preferably, said shading rubber belt sticks on the side of said extension.A light leak towards optical module is maximum,
Preferably, said shading rubber belt sticks on the side of said extension and towards the one side of optical module.Side and all paste shading rubber belt towards the one side of optical module, anti-light leakage effect is better.
Preferably, said shading rubber belt is around the surface that sticks on whole said extension.Whole extension is wrapped up, and it is inner that the light that light source sends has all got into not liquid crystal panel from any angle, further improves light leakage phenomena.
Preferably, said shading member is the shading draw-in groove that is provided with groove, and the extension of said liquid crystal panel is embedded in the said groove.Extension is embedded in the groove, just can realizes omnibearing lucifuge, mounting means is easy.
Preferably, said shading member is that length is followed the consistent shading baffle plate of said light source, and said shading baffle plate one side is arranged on optical module exiting surface edge, and opposite side is arranged on the top of light source near liquid crystal panel one end.This is a kind of shading member in light source side, can prevent that on the one hand light from getting into liquid crystal panel from the liquid crystal panel side, on the other hand, can reduce the space of dispersing of light source, lets more rays get in the optical module, improves the utilization factor of light.
Preferably; Said light source is near forming the light leak space between the top of liquid crystal panel one end and the preceding frame; Said shading member is the glue material assembly that is filled in the said light leak space, and said glue material assembly is provided with the supporting part of the exiting surface that extends to said optical module 600.This is another kind of shading member in light source side, has expired whole light leak space because the shading member is filled, and anti-light leakage effect is better.
The present invention directly gets into the inner shading member of liquid crystal panel owing between light source and liquid crystal panel, be provided with obstruct light from light source; It is inner that the light that sends of light source has just got into not liquid crystal panel like this; Effectively avoided the generation of hot spot phenomenon; Especially do not have in the liquid crystal indicator of center or segmentation center, the edge part branch of liquid crystal panel is directly exposed to the light source irradiation zone, therefore adopts shading member of the present invention can effectively intercept light and gets into liquid crystal panel inside from edge side.
