[embodiment]
Below in conjunction with drawings and Examples, the utility model is 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 is also done 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.
And some technique adopts to arrange one piece of mode making up the white reflector material 90 ' of thickness difference between light guide plate and LED solve lamp eye problem between light guide plate and reflectance coating, as shown in Figure 2: but this white reflector material 90 ' at one end can raise light guide plate, and light guide plate one end is elevated, and it is overall uneven, the side be elevated also can protrude from outside glue frame, easily causes glass corner to burst apart and broken screen when stressed.
So need to propose a kind of more perfect processing scheme: the LCD liquid crystal display module namely involved by the application, please refer to accompanying drawing 3: wherein 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; On light guide plate 50, diffusion barrier 40 is provided with the black shading rubber belt 90 making up difference in height between light guide plate 50 and LED 70 near one end of LED 70.
This black shading rubber belt 90 is arranged between flexible circuit board FPC 100 and diffusion barrier 40, and length is corresponding to LED 70.This black shading rubber belt 90 can not only block the light leaked from the drop between LED 70 and light guide plate 50, and can not have an impact to the position of light guide plate 50, can also protect the corner of light guide plate 50 further, prevent the generation of bursting apart.
This glue frame 80 has the groove that caves in, the reflectance coating 60 of the stacked placement of depth adaptation of this groove that caves in, light guide plate 50, diffusion barrier 60, upper bright enhancement film 20, lower bright enhancement film 30 and shading gummed paper 10, and corresponding with the plurality of stacked film being provided with LED 70 and flexible circuit board FPC 100, the light-emitting area of LED 70 is towards direction, multiple stacked film place.
This flexible circuit board 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 0.065 ~ 0.07mm.
The utility model adopts one black shading rubber belt, 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.And the height too raising light guide plate can be avoided, cause the groove depth of the double faced adhesive tape height plastic emitting frame deposited FPC and paste FPC, and cause easily crumbling corner.The liquid crystal display module that a better quality, experience are better can be obtained after adopting the process of black shading rubber belt.And this solution is simple, cost is told somebody what one's real intentions are, and is suitable for large range promotion use.
The above, it is only the utility model preferred embodiment, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when utilizing the technology contents of above-mentioned announcement or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, any simple modification that above embodiment is done is referred to according to the utility model technology, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
