Along with display module does thinner and thinner, light guide plate also does thinner and thinner thereupon, generally adopt the LED of 0.6mm thickness at present on the market, along with light guide plate constantly thinning LED and the light guide plate of just making there are differences, so just occurred having a height fall between light guide plate and LED, as shown in Figure 1, the light that a part is sent by LED produces light leakage along the drop space at edge, socket place can be caused to there is one bright line bar, " the lamp eye " that be commonly called as in industry.The existence of " lamp eye " can affect the display effect of module.
[summary of the invention]
The utility model proposes a kind of little cost, the simple and convenient LCM backlight module that can solve " lamp eye " problem for above problem.
Described in the utility modelly relate to LCD liquid crystal display module, comprise LCD liquid crystal display, backlight, glass, FPC, polaroid, driving chip and touch-screen, wherein backlight comprises the shading gummed paper of stacked setting, upper bright enhancement film, lower bright enhancement film, diffusion barrier, light guide plate and reflectance coating, be provided with LED in the side of backlight multilayer film material, and glue frame installs fixing all film materials and LED in wherein; The white reflector material that one piece makes up thickness difference between light guide plate and LED is set between light guide plate and reflectance coating.
This reflectorized material is strip, and length is corresponding to LED, and thickness is corresponding to the thickness drop between LED and light guide plate.
The thickness of this reflectorized material is 0.1mm
Be provided with FPC FPC in LED non-luminescent side, this FPC FPC is glued with glue frame and light guide plate respectively mutually by twice double faced adhesive tape.
The thickness of this double faced adhesive tape is 0.1mm.
The utility model adopts one white reflection bar, makes up the thickness drop between light guide plate and LED, avoids LED light line from height fall gap leakage out, the problem of " the lamp eye " that exist before can improving.Obtain the better backlight of a better quality, experience and liquid crystal display module.And this solution is simple, cost is told somebody what one's real intentions are, and is suitable for large range promotion use.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the backlight of original LCD liquid crystal display module;
Fig. 2 is the structural representation of the backlight of LCD liquid crystal display module of the present utility model;
Wherein: 10, shading gummed paper; 20, upper bright enhancement film; 30, lower bright enhancement film; 40, diffusion barrier; 50, light guide plate; 60, reflectance coating; 70, LED; 80, glue frame; 90, reflectorized material; 100, FPC PFC; A, drop space.
[detailed description of the invention]
Below in conjunction with drawings and Examples, the utility model LCD liquid crystal display module and backlight thereof are described in detail.
Problem to be solved in the utility model is the light leakage problem overcoming " lamp eye ".Along with display module does thinner and thinner, light guide plate also does thinner and thinner thereupon, generally adopt the LED of 0.6mm thickness at present on the market, along with light guide plate constantly thinning LED and the light guide plate of just making there are differences, so just occurred having a height fall between light guide plate and LED, please refer to shown in accompanying drawing 1, the light that a part is sent by LED produces light leakage along the drop space A at edge, socket place can be caused to there is one bright line bar, " the lamp eye " that be commonly called as in industry.The existence of " lamp eye " can affect the display effect of module.
Please refer to accompanying drawing 2, the figure illustrate and described in the utility modelly relate to backlight, this backlight comprises the shading gummed paper 10 of stacked setting, upper bright enhancement film 20, lower bright enhancement film 30, diffusion barrier 40, light guide plate 50 and reflectance coating 60, be provided with LED 70 in the side of backlight multilayer film material, and glue frame 80 installs fixing all film materials and LED 70 in wherein; The white reflector material 90 that one piece makes up thickness difference between light guide plate 50 and LED 70 is set between light guide plate 50 and reflectance coating 60.
This reflectorized material 90 is strip, and length is corresponding to LED 70, and thickness is corresponding to the thickness drop between LED 70 and light guide plate 50.
The thickness of this reflectorized material 90 is 0.1mm.Thickness also can select 0.05mm, and generally general in industry is these two kinds of thickness, and mainly will see whether effect meets the requirements, the reflectorized material of 0.1mm thickness is better than the effect of 0.05mm in general.Reflectorized material is with the addition of after 90s below light guide plate, padded up light guide plate from a side, light guide plate is concordant with LED 70, and two planes keep same level, the light then now sent by LED all enters into light guide plate, no longer produces the problem of " light leak ".
Be provided with FPC FPC 200 in LED 70 non-luminescent side, this FPC FPC 100 is glued with glue frame 80 and light guide plate 50 phase respectively by twice double faced adhesive tape 110.
The thickness of this double faced adhesive tape 110 is 0.1mm.The thickness of this reflectorized material is 0.1mm.
And LCD liquid crystal display module involved in the utility model is exactly the module comprising LCD liquid crystal display, backlight, glass, FPC, polaroid, driving chip and touch-screen, backlight is wherein exactly the backlight adopting said structure to be combined into.
