Description
Technical field
The utility model relates to digital demonstration field, more particularly, relates to a kind of with multilayer liquid crystal indicator backlight.
Background technology
In a lot of special industries, display needs by people, to be seen clearly Chu in the sun or under high light, such as automobile rear-view mirror display, in order to allow driver see clearly Chu, need rearview mirror to have bright especially screen, due to a variety of causes, present indicator screen on the market has partially dark phenomenon.Traditional is backlight, is all the backlight of individual layer, and in order to improve the backlight illumination of LCDs, classic method has following several:
1, the unidirectional projection in side is backlight, i.e. and so-called " side throwing ", side is thrown can be divided into again unidirectional survey throwing and multidirectional survey throwing.As shown in Figure 1, it is comprised of upper cover 1, lower cover 2, liquid crystal display glass module 3, screen mount 4, blooming piece module 5, backlight lamp bar 6 and reflection diaphragm 7.What one-way lateral throw to adopt is one direction projection, and from either direction up and down, to the centre position projecting light of screen, then the blooming piece module by every layer of backlight module is 90 ° of anaclasis, then light is projected on screen, by people's naked eyes, seen.Adopt in this way if improve the brightness of screen, conventionally will increase the quantity of light source, but do like this, because space is inadequate, the quantity increase of lamp is restricted, so brightness can not significantly increase, and increases light source and cause backlight regional temperature very high, easily cause screen to work, cause potential safety hazard; What Multidirectional side throw to adopt is multiaspect projection,, from wherein both direction or three directions or four direction up and down, simultaneously to middle projecting light, improves screen intensity.But this method, is subject to the restriction of blooming piece module, generally can only be up and down or the such symmetry direction in left and right, to middle light projector, just can be refracted on screen efficiently by blooming piece module.If from three directions or four direction light projector, be subject to the demonstration of blooming piece module, refractive index is very low, has a strong impact on the utilization factor of light.Meanwhile, this method, can only improve screen intensity to a certain extent, many times cannot meet the demand of user to screen brightness.
2, adopt light to be directly transmitted to the method on screen without refraction.As shown in Figure 2, concrete grammar is, on area aluminum base PCB plate 1 similar to liquid-crystalline glasses, is evenly distributed some lamps 2, and these lamps shine directly on liquid-crystalline glasses 3, produce image and are seen by human eye.Because lamp quantity is a lot, can allow screen very bright, the heat of lamp diffuses away by aluminum base PCB plate.But this method, is easy on the plate of aluminum base PCB one by one in sight the light source point of electroluminescent lamp.That is to say, user sees on screen, has bright spot one by one.In order to eliminate bright spot, can only adopt the distance increasing between lamp plate and liquid crystal display glass, and cause like this expansion of Integral back photosystem volume; In order to eliminate bright spot, can only between lamp plate and liquid-crystalline glasses, increase several layers of optical diffusion sheet 4, and these diaphragms, although weakened bright spot, but seriously hinder the utilization factor of light simultaneously, allow the brightness of screen greatly reduce.And this method manufacturing cost is expensive.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of it is provided with multilayer backlight module with multilayer liquid crystal indicator backlight, can realize the collocation of various backlight projecting directions, thereby can reach the effect of the super bright demonstration of display screen.The utility model adopts simple structure, can solve the problem that traditional product manufacturing cost is high, display quality is low.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of with multilayer liquid crystal indicator backlight, it comprises upper cover, lower cover, liquid crystal display glass module and the fixing screen mount of liquid crystal display glass module, the below of described liquid crystal display glass module is provided with at least two layers or more backlight module from top to bottom successively, described backlight module comprises the backlight lamp bar that is arranged on screen mount, is located at backlight lamp bar thermal grease and blooming piece module below, between described adjacent two layers of backlight module, be provided with Unidirectional transparent diaphragm, the bottom of the backlight module of the described bottom is provided with total reflection light diaphragm.
Described every group of backlight module can arrange a group or more backlight lamp bar.
Described backlight lamp bar is arranged at a side of backlight module or in many ways.
Described every layer of backlight module can be from any one direction of four direction or several direction projections wherein up and down.
The utility model adopts said structure, adopts the method for side projection light, and cumulative a lot of layer is backlight simultaneously, the light that allows the backlight module of lower floor launch up, through upper strata backlight module, final, the light of several layers of backlight module, is all irradiated on screen, produces the brightness effects of excess.The light of every layer, can be from up and down, and one of them direction or multiple directions, simultaneously to middle projecting light, then by blooming piece module, by 90 ° of light refractions, project screen and get on.Meanwhile, the number of plies of light, can increase arbitrarily according to individual demand.Between every two groups of adjacent blooming piece modules, all adopt Unidirectional transparent diaphragm, make the light of below be easy to project, and the light on upper strata is difficult to be penetrated into lower floor, can greatly reduce like this light in the invalid reflection of several layers of centre backlight, improve the utilization factor of overall light.The bottom of backlight module, adopts total reflection light diaphragm.Liquid-crystalline glasses shows module, is the combination of multiple material, comprises the material layer of the various functions such as liquid crystal display glass, polaroid; The blooming piece module of every layer of backlight module, can be light polarizing film, DEBF, diffusion barrier, the combination of the various blooming pieces such as brightness enhancement film, finally combines, the light that side transmission is come in realization, reflects 90 ° expeditiously, projects on liquid crystal display glass module.
After reading by reference to the accompanying drawings the detailed description of embodiment of the present utility model, it is clearer that feature of the present utility model and advantage will become.
