Abstract
The utility model relates to a computer peripheral technical field, specifically speaking relates to a liquid crystal display of anti -dazzle. The utility model discloses a backlight unit, backlight unit includes the light guide plate and lies in the light source of light guide plate one side that the play plain noodles of light guide plate is equipped with the diffusion piece, the light source includes the PCB board and is fixed in the LED of PCB board, the PCB board is close to the one end of diffusion piece and extends the formation portion of being in the light to the light guide plate. The utility model discloses a set up the portion of being in the light on the PCB board, can avoid LED light direct projection to go into the liquid crystal, avoid appearing the glare.
Description
Technical field
This utility model relates to computer peripheral technical field, specifically, relates to the LCDs of a kind of anti-dazzle.
Background technology
Along with developing rapidly of electronic technology, electronic product is constantly weeded out the old and bring forth the new, electronic product great majority use LCDs to use as display screen at present, LCDs is in use, the content on liquid crystal display screen is shown by backlight module luminescence, at present when using LCDs, some angle there will be dazzle, occur that dazzle is primarily due to that current LCDs does more and more thinner, the light that the light source of backlight module sends is projected directly on liquid crystal, then when casting out, light relatively by force thus forms dazzle.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that the LCDs of a kind of anti-dazzle.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
The LCDs of a kind of anti-dazzle, including backlight module, described backlight module includes light guide plate and is positioned at the light source of light guide plate side, and the exiting surface of light guide plate is provided with diffusion sheet；Described light source includes pcb board and is fixed on the LED of pcb board, and described pcb board extends to light guide plate near one end of diffusion sheet and forms light-blocking part.
Further, the shady face of described light guide plate is provided with reflecting piece.
Further, described light-blocking part is obliquely installed, and the end of light-blocking part offsets with light guide plate.
Further, divergent lens it is provided with between LED and light guide plate.
Further, the outside of described diffusion sheet is provided with prism film group；Prism film group includes prism film and lower prism film, and upper prism film surface is provided with a plurality of parallel upper projection, and lower prism film surface is provided with a plurality of parallel lower convexity, and the extending direction of upper projection is vertical with the extending direction of lower convexity.
What this utility model obtained has the beneficial effect that this utility model to pass through on pcb board to arrange light-blocking part, LED light line can be avoided directly to project into liquid crystal, it is to avoid dazzle occur.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Reference is:
1 pcb board 2 divergent lens 3 LED
Projection on prism film 6 on 4 reflective membranes 5
7 liquid crystal display screen 8 reflecting piece 9 light guide plates
10 times prism film 11 lower convexity.
Detailed description of the invention
Below in conjunction with the accompanying drawings 1 and detailed description of the invention this utility model is described further.
Embodiment 1: see Fig. 1.
The LCDs of a kind of anti-dazzle, including backlight module, the light direction of backlight module is provided with liquid crystal display screen 7, and described backlight module includes light guide plate 9 and is positioned at the light source of light guide plate 9 side, and the exiting surface of light guide plate 9 is provided with diffusion sheet；Described light source includes pcb board 1 and is fixed on the LED3 of pcb board 1, and described pcb board 1 extends to light guide plate 9 near one end of diffusion sheet and forms light-blocking part.
The technical program uses the means arranging light-blocking part in one end of light guide plate 9 to overcome light to enter the defect of liquid crystal display screen, thus realizes preventing light from concentrating at local angle, it is to avoid dazzle occurs.Simultaneously so that light guide plate 9 to go out light more uniform, be provided with diffusion sheet.Preferably, light guide plate 9 is provided with the groove matched with light-blocking part near the side of LED3.Yet further, the other end of pcb board 1 also extends to light guide plate 9 and forms light-reflecting portion, can improve light utilization further, and pcb board 1 takes the shape of the letter U.
Further, the shady face of described light guide plate 9 is provided with reflecting piece 8.
Reflecting piece 8 is set and can improve light utilization.
Further, described light-blocking part is obliquely installed, and the end of light-blocking part offsets with light guide plate 9.
Light-blocking part is obliquely installed so that light can be reflexed to light guide plate 9 by light-blocking part.Secondly, the end of light-blocking part abuts with light guide plate 9, is possible to prevent light leakage.Avoid dazzle.
Further, divergent lens 2 it is provided with between LED3 and light guide plate 9.
LED3 is point source, and point source illumination intensity distributions when carrying out light projection is uneven, so that light enters light guide plate 9 homogenization, is provided with divergent lens 2.Divergent lens 2 can be concavees lens, it is also possible to for compound lens.
Further, the outside of described diffusion sheet is provided with prism film group；Prism film group includes that prism film 5 and lower prism film 10, upper prism film 5 surface are provided with a plurality of parallel upper protruding 6, and lower prism film 10 surface is provided with a plurality of parallel lower convexity 11, and the upper extending direction of protruding 6 is vertical with the extending direction of lower convexity 11.
Prism module can allow light alignment axial direction assemble, and reduces light projection drift angle, improves light utilization.In order to improve effect, it is preferable that upper projection 6, lower convexity 11 undulate.
Below being only the preferred embodiment of the application, equivalent technical solutions on this basis still falls within application protection domain.
