Abstract
The utility model relates to a kind of novel backlight module, comprises light guide plate and backboard, the diffuser plate that the side of described light guide plate is arranged in parallel, and described backboard is provided with LED, and described backboard is arranged in the side of diffuser plate.The utility model employs the higher diffuser plate of mist degree and replaces original blooming piece, and optical effect is identical with diaphragm, and cost reduces by a relatively large margin, largely promotes packaging efficiency, reduces the fraction defective of traditional optical diaphragm in backlight module processing procedure simultaneously.
Description
Technical field
The utility model relates to field of liquid crystal display, particularly relates to a kind of novel backlight module.
Background technology
Liquid crystal indicator (LCD, Liquid Crystal Display) has that fuselage is thin, power saving, the many merits such as radiationless, be widely used.Liquid crystal indicator major part on existing market is backlight liquid crystal display, and it comprises display panels and backlight module (backlight module).
The operation principle of display panels places liquid crystal molecule in the middle of the glass that two panels is parallel, the two tiny electric wires having many vertical and levels in the middle of sheet glass, change direction by whether being energized to control liquid crystal molecule, the light refraction of backlight module is out produced picture.Because display panels itself is not luminous, the light source provided by backlight module is needed to carry out normal show image, therefore, one of backlight module key part and component becoming liquid crystal indicator.Backlight module is divided into side entrance back module and down straight aphototropism mode set two kinds according to the difference of backlight incoming position.Down straight aphototropism mode set is by backlight such as CCFL (Cold Cathode Fluorescent Lamp, cathodouminescence fluorescent tube) or LED (Light Emitting Diode light emitting diode) be arranged on display panels rear, direct forming surface light source is supplied to display panels.And side entrance back module is by backlight, as LED backlight (lightbar), be located at the back plate edges of display panels proceeds posterolateral, the light that LED backlight sends enters light guide plate from the incidence surface of light guide plate side, from the outgoing of light guide plate exiting surface after reflection and diffusion, be supplied to display panels with forming surface light source.
Existing backlight module mainly comprises: backboard, light guide plate, CCFL or LED lamp source and blooming piece, wherein blooming piece is that wherein cost is higher, also be very important parts, the blooming piece used in present backlight module is still the higher import diaphragm of price, price is high, and is in use easy to damage.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel backlight module, employ the higher diffuser plate of mist degree and replace original blooming piece, optical effect is identical with diaphragm, cost reduces by a relatively large margin, largely promote packaging efficiency, reduce the fraction defective of traditional optical diaphragm in backlight module processing procedure simultaneously.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of novel backlight module, comprise light guide plate and backboard, the diffuser plate that the side of described light guide plate is arranged in parallel, described backboard is provided with LED, and described backboard is arranged in the side of diffuser plate.
As a kind of preferred version of the present utility model, straight-down negative structure: described slim diffuser plate is placed in the upside of thick diffuser plate, the parallel beneath of described thick diffuser plate is furnished with backboard, the upper surface of this backboard is evenly provided with several LED, one end of described backboard by swash plate be connected buckle and be connected with one end of diffuser plate.
As another kind of preferred version of the present utility model, side entering type structure: described light guide plate is arranged in the downside of diffuser plate, described backboard is L-shaped, and its minor face side plate is vertically arranged and madial wall is provided with LED, and described LED faces one end of light guide plate.
beneficial effect
The utility model relates to a kind of novel backlight module, employ the higher diffuser plate of mist degree and replace original blooming piece, optical effect is identical with diaphragm, and cost reduces by a relatively large margin, largely promote packaging efficiency, reduce the fraction defective of traditional optical diaphragm in backlight module processing procedure simultaneously.
