Abstract
This invention discloses a sort of vertical type back-light module, and this module consists of several cold cathode strip lamps which are distributed abreast, the reflector plate which is under the cold cathode strip lamp and is used for reflecting the ray which is emitted by this cold cathode strip lamp, the lamp holder which fixes this cold cathode strip lamps, and the backboard which supports and fixes this reflector plate and lamp holder. This cold cathode strip lamp is fixed by the clasp of the lamp holder, and there has the backboard flute in this backboard, this deepness of this backboard flute is not less than the base thickness of the lamp holder, and this lamp holder is fixed in the backboard flute, and this reflector plate glues in the backboard in order to make the lamp holder to be fixed between the reflector plate and the backboard. The vertical type back-light module of this invention resolves the problem that the lamp holder loads the asymmetric brilliance of the back-light power effectively.
Description
Technical field
The present invention relates to field of liquid crystal, particularly a kind of down straight aphototropism mode set of LCD.
Background technology
At present, large-sized display panels has adopted down straight aphototropism mode set in a large number.Down straight aphototropism mode set is with a plurality of cold cathode fluorescent lamp (CCFL) version under the viewing area placed side by side, and Fig. 1 is existing down straight aphototropism mode set synoptic diagram, and Fig. 2 is that the A-A of down straight aphototropism mode set among Fig. 1 is to the broken section enlarged diagram.As shown in the figure, down straight aphototropism mode set comprises backboard 1, reflector plate 2, lamp socket 3, cold cathode fluorescent lamp 4.Backboard 1 plays the effect of support and fixation reflex sheet 2 and lamp socket 3.Cold cathode fluorescent lamp 4 is the light source of down straight aphototropism mode set.Lamp socket 3 plays the effect of stationary positioned cold cathode fluorescent lamp 4.Reflector plate 2 plays the effect of the light that sends of reflection cold cathode fluorescent lamp 4.Every cold cathode fluorescent lamp is fixing by the snap ring on the lamp socket 3 31, to guarantee that fluorescent tube is apart from the distance between distance, fluorescent tube and the fluorescent tube of reflector plate 2 on the backboard 1 and the intensity of fluorescent tube.Reflector plate 2 is attached on the metal backing 1, and lamp socket 3 is positioned on the reflector plate 2, and lamp socket 3 is fixed on the metal backing 1 by the reflector plate 2 that passes of the grab on the lamp socket 3 32.
Existing down straight aphototropism mode set since the reflectivity of reflector plate material and the reflectivity of lamp socket material there are differences, there is a difference in height in the reflecting surface of lamp socket apart from the reflector plate reflecting surface simultaneously, thereby cause the light that sends by fluorescent tube through lamp socket reflection penetrate the difference that back and light have on every side had briliancy, caused the unevenness (Mura) of backlight briliancy.
Summary of the invention
The purpose of this invention is to provide a kind of down straight aphototropism mode set, by changing the assembling position of reflector plate and lamp socket, to solve because the different luminance nonuniformity problems that cause of lamp socket material reflectance with reflector plate material reflectivity.
For achieving the above object, down straight aphototropism mode set of the present invention, comprise: side by side a plurality of cold cathode fluorescent lamp of Fen Buing, be positioned at cold cathode fluorescent lamp below, be used to reflect the lamp socket of reflection of light sheet that described cold cathode fluorescent lamp sends, the described cold cathode fluorescent lamp of stationary positioned and support and the backboard of fixing described reflector plate and described lamp socket; Described cold cathode fluorescent lamp is fixed by the snap ring on the lamp socket; Described backboard is provided with the backboard groove, and the degree of depth of described backboard groove is not less than the base thickness of lamp socket, and described lamp socket is fixed in the backboard groove, and described reflector plate is attached on the backboard, and lamp socket is installed between reflector plate and the backboard.
Described lamp socket is fixed in the backboard groove by grab.
Described lamp socket can also be adhesively fixed in the backboard groove by double sticky tape.
The present invention is arranged on lamp socket in the backboard groove on the backboard, and reflector plate is attached on the surface of lamp socket and backboard.This mode has been avoided the different luminance nonuniformity problems that cause with reflector plate material reflectivity of lamp socket material reflectance, has also overcome the problem of the luminance nonuniformity that the difference in height of lamp socket reflecting surface and reflector plate reflecting surface causes.Thereby in the phenomenon that has fundamentally effectively solved the backlight luminance nonuniformity that lamp socket causes.
