Abstract
The present invention is a kind of LCD backlight display effect optimization structure, including light guide plate, light source and reflector plate, described reflector plate is located at guide-lighting back, the light source is on two parallel sides of light guide plate correspondence, the reflector plate is provided with groove, the two ends on the both sides that the groove intersects located at reflector plate with the light source side of light guide plate.Belong to the technical field of electronic product.Purpose, which is to provide one kind, fundamentally can thoroughly solve LCD under white displays picture, there is the uneven phenomenon of display by light source side, the problem of there is different degrees of speck, and the production cost of its product can also be reduced, the qualification rate of product is also to step up, and what is more important causes the more perfect LCD backlight display effect optimization structure of the effect of liquid crystal display.
Description
Technical field
Structure is shown the present invention relates to a kind of LCD backlight, particularly a kind of LCD backlight display effect optimization structure.
Background technology
There is the uneven phenomenon of display under white displays picture by light source side in existing LCD, that is, occurs different degrees of
Speck.Specifically when LCD is placed in darkroom, we are not difficult to find out by light source lateral edges bright border substantially, its light
Learn principle：Light guide plate has the effect of guide-lighting and optically focused, and more brighter by light source side light source, the light that LED is issued passes through light guide plate
Surrounding is led, when light reaches light-guide edge, light-guide edge reflects a part of light and come out again, reaches the inner side of glue frame,
The material of glue frame is PC white (reflectivity is strong), then the light reflected is reflected back into light guide plate, while some light is anti-
It is mapped to reflector plate direction, it can be seen that the light guide plate surrounding for removing reflector plate is very bright, brighter by light source side, is covered when reflector plate
When, the light that edge is shot out is reflected back again, so it is also strong just to occur that the strong local reflector plate of light is reflected back, is made
Obtain viewing area edge high (speck) by light source corner brightness.And to be always that LCD industries are the most intractable for such a problem ask
Topic, is also technological difficulties.
Reason is when taking the reflector plate inside LCD apart, it is found that light-guide edge optically focused is particularly evident, and produce at present
When perfection in order to pursue display picture it is uniform, be by the way of mostly：
First, the area of light guide plate is increased so that light-guide edge is away from viewing area, but the defect so done is：
So that the overall brightness deterioration of LCDs, the big cost of guide-lighting plate suqare can also increase.
Second, shading glue is changed to black glue, by black glue extinction, but surrounding extinction is substantially, and brightness declines, and uses this
Plant solution and not can effectively solve the problem that problems.
3rd, it is by increasing reflector plate so that its all standing light guide plate, and if using such a design still to have
Edge bright border, is usually taken processing light guide plate illumination effect to solve, but processing light guide plate has several difficult points, is cost first
It is high；Next to that dealing with of long duration, delay the cycle that product enters market so that just without market competition when it enters market
Power；Furthermore it is just that bright border problem is addressed, its bright border solved is still not enough thoroughly, is also exactly to have handled it well
Afterwards, it is also unstable the problem of the bright border so that it can have vicious circle repeatedly, finally bright border problem can not be obtained very
Good solution.
In summary, it is really, significantly, thoroughly to solve not have a kind of scheme in existing solution
Liquid crystal display module is uneven there is display by light source side under white displays picture in other words for available liquid crystal display screen
Phenomenon, that is, the problem of there is different degrees of speck.
The content of the invention
The invention aims to solve LCDs or perhaps liquid crystal display module under white displays picture,
There is the uneven phenomenon of display, that is, the problem of different degrees of speck occur by light source side, and a kind of LCD backlight is provided
Display effect optimizes structure.
A kind of LCD backlight display effect optimizes structure, including light guide plate, light source and reflector plate, and described reflector plate is located at
Guide-lighting back, the light source is on two parallel sides of light guide plate correspondence, and the reflector plate is provided with groove, the groove
At the two ends on the both sides intersected located at reflector plate with the light source side of light guide plate.
Further, described groove is rectangle.
Further, described rectangular inner side edge inside contracts 0.3 to 0.5MM on the basis of light-guide edge, the length
Square length direction be 8 to 16MM, and by light source side, the distance of rectangular length direction to edge of display area be 3 to
6MM。
It is using the beneficial effect of above-mentioned technical proposal：Not only fundamentally thoroughly solved using the technical scheme in this programme
Certainly is there is the uneven phenomenon of display by light source side, that is, different degrees of speck is occurring under white displays picture in LCD
Problem, and the production cost of its product can also reduce, and the qualification rate of product is also to step up, and what is more important makes
The effect for obtaining liquid crystal display is more perfect.

Embodiment
Present disclosure is further described below in conjunction with accompanying drawing and currently preferred specific embodiment.Lifted
Example is served only for explaining the present invention, is not intended to limit the scope of the present invention.
As shown in Figure 1 to Figure 3, this programme is that a kind of LCD backlight display effect optimizes structure, including light guide plate 1, light source
2 and reflector plate 3, described reflector plate is located at the back side of light guide plate 1, and the light source 2 is located at two parallel sides of the correspondence of light guide plate 1
On, the reflector plate 3 is provided with groove 4, the both sides that the groove 4 intersects located at reflector plate 3 with the side of light source 2 of light guide plate 1
At two ends.Groove 4 described in this programme is rectangle.Can certainly can be reached using other in the technical program
Described other shapes, and rectangle is used in this programme.In this programme, described rectangular inner side edge is to lead
0.3 is inside contracted on the basis of tabula rasa edge to 0.5MM, the rectangular length direction be 8 to 16MM, it is rectangular and by light source side
The distance of the length direction of shape to edge of display area is 3 to 6MM；And the rectangular inner side edge described in this programme is with leaded light
The length inside contracted on the basis of edges of boards edge is controlled in 0.4MM, and the rectangular length direction is 11.09MM, and by light source one
Side, the distance controlling of rectangular length direction to edge of display area is in 4.31MM, and what is reached goes the effect ability of speck
Reach optimal.Because in concrete operations, if the size design of groove it is too big or too small can all be possible to produce it is negative
Face rings, and size is big, and shadow occurs in viewing area, and size is small, and viewing area speck can not be eliminated；Only follow the above
Size principle could realize perfect display effect.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
