Backlight can be made more uniform.
Based on the structure of above-mentioned even mating plate 10, this programme also proposed a kind of LCD modules using the even mating plate 10.
Please referring also to 9 and Figure 10, a kind of LCD modules, it includes circuit board 60, LCD supports 20, even mating plate 10, LCD screen
30 and LCD screen cover 40, wherein, the separable top for being fixed on circuit board 60 of LCD supports 20, even mating plate 10 and LCD screen 30 are set
In the inside of LCD supports 20, and LCD screen 30 is arranged on the surface of even mating plate 10, and the cover of LCD screen cover 40 is penetrated in LCD supports 20
Outside, its top is formed with the window 41 for being available for LCD screen 30 to expose.
Multiple LED61 are evenly arranged with circuit board 60, the light that LED61 is produced is sent to through the inside of LCD supports 20
Even mating plate 10, then by the folding inside even mating plate 10 repeatedly, reflection after by produce uniform light directive LCD screen 30 schedule to last carry
For uniform backlight.
Even mating plate 10 is the foregoing structure of even mating plate 10, and here is omitted.
Please referring also to 11, LCD supports 20 are in rectangular-shape, and it is internally formed the groove that both sides are descended in an insertion thereon
21, it is respectively formed with a reflector 22, two on two relative inwalls of the long side direction along LCD supports 20 on groove 21
Reflector 22 in mirror image set and be formed with each other obtuse angle angle but and it is non-intersect, LED61 can be correspondingly arranged at two
Between the bottom angle of individual reflector 22；Also, continuing surface 23 is formed with the top end face of reflector 22, even mating plate 10 can quilt
It is arranged on the continuing surface 23.

Smooth surface level is processed as on 22 relative inner surface, period can realize the reflection to light.
The material of the pcb board of circuit board 60 is FR-4, and silk-screen is white reflective oil high on the pcb board surface on LED61 peripheries
Paint.
The edge of LCD screen 30 is bent to form multiple pins 31 being set up in parallel, and LCD screen 30 is fixed on LCD supports 20
When on continuing surface 23, its pin 31 can be downwardly on the pcb board of circuit board 60, and is fixed by welding.
The operation principle of the LCD modules of this programme is to refer to Figure 12, when LED61 is projected with 60 ° of light of angle
When, light 51 is projected, light 52 is reflected by the light surface side wall of reflector 22, then light 53 is reflected, then inject even mating plate
In 10；There is some light by being reflected into light 55, light 55 reflects light 56, light by the light surface side wall of reflector 22 again
Line 56 reflects light 57 by the white oil on circuit board again.
Please referring also to Figure 13, such as Fig. 2, anti-using what is constantly repeated in even mating plate after light 54 injects even mating plate 10
Penetrate, reflect, the principle such as diffusing reflection, light 71 reflects light 72, and reflection light 73 by even mating plate inside hexagonal groove,
Reflection light 73 is again by reflecting light 74 and reflecting light 35.
By with optical principles such as continuous refraction, reflection, the diffusing reflections of glazed thread, making LED61 continuous in LCD module internals
Circulation, is capable of the loss of maximized reduction light ray energy, reaches energy-efficient effect.
To make to be easy to illustrate this programme, the optical analog figure using the even mating plate of this programme is observed by emulation experiment：
Figure 14 and Figure 15 is referred to, used as a kind of contrast test, it uses two LED lamps as backlight, and the even of this programme is not added
Mating plate makees optical analog effect, and its test effect is it is seen that the light of two LEDs projection is respectively formed with a round shape
Hot spot, it is envisioned that, the spacing between two LED can directly affect the spacing between two hot spots, therefore, two hot spots
May intersect, may possibly be separated, some dark spaces will certainly be produced, so as to directly affect light-out effect.
Figure 16 and 17 is referred to, is tested as the implementation of this programme, using two LED lamps as backlight, and added
The even mating plate of this programme makees optical analog effect, and its test effect is it is seen that the light of each LED projections can produced
Product inside can make light be covered with whole even mating plate by the diffusing reflection, the refraction that constantly repeat, so as to reach the effect of even light, and
And, dark space will not be produced because of the distance between two LED, make light extraction more uniform complete.
By above-mentioned contrast test, it can be seen that using the even mating plate of this programme, even light effect and high rate can be reached
Through effect.
To sum up, even mating plate of the invention and the LCD modules using the even mating plate, by the first light guide sheet and the second light guide sheet
Integral even mating plate bonded to each other, also, forming multiple just respectively on the joint face of the first light guide sheet and the second light guide sheet
The groove of six prism-frustum-shapeds, and spliced by the dislocation of the first light guide sheet and the second light guide sheet, so as to form one in cellular even
Light area, extraneous light enter even mating plate after, using the scattering of light, diffusing reflection and refraction principle, make light inside even mating plate not
Disconnected scattering, diffusing reflection, refraction, reduces the loss of light ray energy, reaches the effect of even light and rate thoroughly high.Even mating plate of the invention
