Abstract
The utility model relates to an eliminate light guide plate of lamp shadow, a side of light guide plate is the income plain noodles that is used for making the light incidence, side going into the plain noodles sets up one row at least LED lamp, interval between the two adjacent lamps on this the LED lamp is M, the length of every LED lamp is N, the LED lamp is D with the perpendicular distance that the plain noodles is gone into to the light guide plate, on the light guide plate, the face is respectively the plane of reflection of light beam and the play plain noodles that makes the even outgoing of light down, be equipped with the site on the play plain noodles, set up first compensating basin and second compensating basin on a plain noodles near the within range that LED lamp side genesis length is 1.732D. The process the utility model discloses a light guide plate, the lamp shadow district obtains fine compensation, whole light homogeneous, and the design is simple, easily operation, and general engineer can realize.
Description
Technical field
This utility model relates to light guide plate technology neighborhood, a kind of light guide plate eliminating lamp shadow.
Background technology
Line source can be changed into area source because of it by light guide plate, is the key component of backlight module, backlight mould
Group is the supplier of liquid crystal display (LCD) light source, and LCD itself is the most luminous, the performance of backlight module light source
Just the visual experience effect that display shows outer is determined.
Owing to the available space in backlight module is fewer and feweri, mutually to melt between the design of each parts
Close.Such as, the binding post of backlight module LED lamp bar and LED are in same side, and binding post accounts for
With a part of space, this LED of spatially can not arranging, and then formation on the light guide plate at this position
Lamp shadow region.When only arranging LED in the one side of light guide plate in backlight module, light guide plate is not by LED
Just area light can be weaker than LED just to central area, lamp shadow occur, thus have impact on LCDs
Display effect.Even if increasing and arranging LED lamp bar, the problem that can not effectively solve lamp shadow, and can improve
Production cost.
Chinese invention patent application CN 102537754 A discloses the preferable light luminance of a kind of acquisition with uniform
The method going out light, by with the distance of LED light source determine site arrangement density degree gradual change
Formula arrangement mode, is all adjusted the site of whole exiting surface, and its design is complex, wastes time and energy,
Increase production cost.
Utility model content
Problem to be solved in the utility model is the deficiency overcoming prior art to exist, and attempts solving light guide plate
The problem of lamp shadow.
Concrete scheme is as follows:
A kind of light guide plate eliminating lamp shadow, a side of light guide plate is for making the incidence surface of light,
Arrange at least one row's LED in the side of incidence surface, the spacing between adjacent two lamps of this LED is M,
The a length of N of every LED, the vertical dimension of LED and light guide plate incidence surface is D, light guide plate upper,
Lower face is to reflect the reflecting surface of light and make the exiting surface of uniform light outgoing respectively, and exiting surface is provided with net
Point, arranges the first compensating basin and at exiting surface in the range of the LED a length of 1.732D of side genesis
Two compensating basins, the first described compensating basin is long N, the rectangle of a width of 1.732D, this first compensating basin Intranet
The reinforcement strength of point is N/M, and the second described compensating basin is long M, the rectangle of a width of 1.732D, and this is second years old
The reinforcement strength of site, compensating basin is M/N, and the first described compensating basin and the second compensating basin are arranged alternately, and
Gap between second compensating basin, two lamps adjacent with LED is the most right, and the first compensating basin is the most right with every LED.
Further, described site is triangle or circle.
Through the light guide plate of this utility model design, lamp shadow district is well compensated, and overall light is homogeneous,
And design is simple, it is easy to operation, general engineering technology personnel can realize.
Accompanying drawing explanation
Fig. 1 is the structural representation of the light guide plate eliminating lamp shadow that this utility model embodiment 1 provides；
Fig. 2 is the compensating basin schematic diagram of the light guide plate eliminating lamp shadow that this utility model embodiment 1 provides.
Detailed description of the invention
With embodiment, technical solutions of the utility model are further elaborated below in conjunction with the accompanying drawings, present embodiment
Can have different forms and be not understood as limited to explanation set forth herein.Accompanying drawing mark identical in literary composition
Note represents identical element all the time, and similar reference represents similar element.
Embodiment 1:
A kind of light guide plate eliminating lamp shadow, as it is shown in figure 1, light guide plate side is for making light

The exiting surface penetrated, exiting surface is provided with site, and site is triangle, including main body dot area 1 and change
Dot area 2, arranges row's LED 3 in the side of incidence surface, between adjacent two lamps of this LED between
It is 1cm away from the vertical dimension for 2cm, a length of 1cm of every LED, LED and light guide plate incidence surface.
It is change dot area 2 in the range of the LED a length of 1.732cm of side genesis at exiting surface,
As in figure 2 it is shown, this region is provided with the first compensating basin 4 and the second compensating basin 5, the first described compensating basin 4 is
Long 1cm, the rectangle of a width of 1.732cm, in this first compensating basin, the reinforcement strength of site is 1/2, i.e. cuts down
To half, the second described compensating basin is long 2cm, the rectangle of a width of 1.732cm, this second compensating basin net
Point reinforcement strength be 2, the first described compensating basin and the second compensating basin are arranged alternately, and the second compensating basin with
Gap between adjacent two lamps of LED is the most right, and the first compensating basin is the most right with every LED.
Embodiment 2
The present embodiment is substantially the same manner as Example 1, and difference is, light guide plate exiting surface in embodiment 1
Site is triangle, and in the present embodiment, light guide plate exiting surface site is circular.
Although above it has been shown and described that embodiment of the present utility model, it is to be understood that above-mentioned reality
It is exemplary for executing example, it is impossible to be interpreted as that, to restriction of the present utility model, those of ordinary skill in the art exists
Without departing from can be to above-mentioned reality in the range of this utility model in the case of principle of the present utility model and objective
Execute example to be changed, revise, replace and modification.
