Description
Technical field
The utility model relates to the backlight module applied in a kind of display unit.
Background technology
In recent years, the technology of liquid crystal indicator is gradually ripe.Along with hobby and the requirement increase of consumer, liquid crystal indicator also moves towards ultrathin gradually.For asking the object reaching ultrathin, each part of liquid crystal indicator all needs the reduction carrying out thickness, such as display floater, blooming piece and backlight module.Wherein backlight module is because of needs mixed light space, and required thickness is usually comparatively large, has therefore also become the target of mainly carrying out reduced down in thickness.
Backlight module generally comprises bearing frame (glue frame or chase), light guide plate, reflectance coating, diffusion barrier, bright enhancement film and shading glue, and light guide plate, reflectance coating, diffusion barrier, bright enhancement film and shading glue are all neat being arranged in bearing frame usually.Pursuing lightening today to various electronic product, backlight module also thins down.The procedure for producing of slimming to product of LED-backlit module brings a series of problem, and especially show edge display bright line and light leak, production efficiency is low, and product yield is low not good with structural stability.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of back light module unit structure, and each parts diaphragm is installed in a step-wise manner, ensures that light-guide edge light can not drain to visible area.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of back light module unit structure, comprise the chase and glue frame that mutually clamp, and the reflectance coating, light guide plate, diffusion barrier, bright enhancement film and the shading glue that are arranged on glue frame, described reflectance coating is installed between chase and glue frame, light guide plate to be installed on glue frame and and between reflectance coating, there is gap, diffusion barrier is located on light guide plate, and bright enhancement film is located on diffusion barrier, and shading glue is located on diffusion barrier.
Described glue frame is provided with the step position be arranged above and below being respectively used to clamp shading glue, diffusion barrier, light guide plate.
The edge of described diffusion barrier, bright enhancement film and shading glue blocks the edge of light guide plate.
There is between described diffusion barrier and glue frame inwall the gap of 0.05 ~ 0.5mm.
There is between described bright enhancement film and glue frame inwall the gap of 0.05 ~ 0.5mm.
Described bright enhancement film is made up of upper bright enhancement film and lower bright enhancement film.
Between described reflectance coating and glue frame, there is gap.
The utility model by arranging multiple step position on glue frame, light guide plate, diffusion barrier and bright enhancement film, shading glue are separately positioned on different step positions, each parts are made to be cascade arrangement structure, ensure that light-guide edge light can not drain to visible area, effectively solve the problem of LCD MODULE edge light leak and bright line.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model part section structural representation;
Accompanying drawing 2 is the cross-sectional view at another visual angle of the utility model.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figure 1 and 2, the utility model discloses a kind of back light module unit structure, comprise the chase 1 and glue frame 2 that mutually clamp, and the reflectance coating 5, light guide plate 7, diffusion barrier 4, bright enhancement film 6 and the shading glue that are arranged on glue frame 2., described reflectance coating 5 is installed between chase 1 and glue frame 2, light guide plate 7 to be installed on glue frame 2 and and between reflectance coating 5, there is gap, diffusion barrier 4 is located on light guide plate 7, bright enhancement film 3 is located on diffusion barrier 4, and shading glue 3 is located on bright enhancement film 6.Glue frame is provided with multiple step position be interspersed that is arranged above and below, and light guide plate is installed on nethermost step position, and diffusion barrier and bright enhancement film are mounted on a step position above light guide plate, and shading glue is then installed on a uppermost step position.Thus shading glue, bright enhancement film and diffusion barrier, light guide plate and reflectance coating are staged distributed architecture.And certain interval will be set between reflectance coating and light guide plate, guarantee that the site of light guide plate can not produce with reflectance coating and rub, guarantee can not produce white point and scratch bad problem.Bright enhancement film 6 is made up of lower bright enhancement film 61 and upper bright enhancement film 62.
In addition, the edge of diffusion barrier, bright enhancement film and shading glue blocks the edge of light guide plate, namely the edge exceeding light guide plate is crossed at the edge of diffusion barrier, the edge exceeding diffusion barrier is then crossed at the edge of lower bright enhancement film, the edge exceeding lower bright enhancement film is then crossed at the edge of upper bright enhancement film, this frame mode, can cover edge bright line on the one hand, and interlocking between light guide plate and glue frame, can be formed on the other hand, whole product is melted as a whole.
In addition, there is between diffusion barrier and glue frame inwall the gap H of 0.05 ~ 0.5mm.There is between bright enhancement film and glue frame inwall the gap H of 0.05 ~ 0.5mm.Concrete numerical value, can select setting within the scope of above-mentioned difference flexibly.
In addition, between reflectance coating and glue frame, there is gap.Especially, for frame, reflectance coating is preferably done monolateral fixing, can guarantee that reflection can not produce displacement on the one hand, also can meet the Swelling and contraction characteristic with humiture of product on the other hand.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
