Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
Provide a kind of backlight to detect tool in the present embodiment, it can be in the backlight assembly process, especially in the secondary screen back light source part component process of double-screen liquid-crystal display device, for providing light source in each optical diaphragm assembly process, thereby in time find the bad of each blooming piece of backlight.
Fig. 5 is to Figure 9 shows that the backlight among first kind of embodiment provided by the utility model detects tool.To shown in Figure 9, the backlight that provides in the present embodiment detects tool and comprises as Fig. 5:
One transparency carrier 100 has relative first and second, and first face is provided with for the groove 101 of placing detected material;
Be arranged at the light tube group 200 in the transparency carrier 100, be arranged at a side of groove 101; And,
Be arranged at second reflector plate 300 of transparency carrier 100.
The backlight that such scheme provides detects tool, by establishing groove 101 first of transparency carrier 100, establish light tube group 200 in groove 101 1 sides, and establish reflector plate 300 second of transparency carrier 100, thereby, can be with backlight, especially each blooming piece of the secondary screen back light source part of double screen backlight carries out assembly in groove 101, thereby provide the light source support in each the optical diaphragm assembly process for backlight, foreign matter on each blooming piece of timely discovery backlight, scratch, bad phenomenon such as dirty, solve each blooming piece no light source support in component process of secondary screen back light source part in the double-screen liquid-crystal display device in the prior art, can not in time find bad problem.
The backlight that provides in the present embodiment detects tool, preferably, transparency carrier 100 adopts the material identical with light guide plate in traditional backlight, namely, transparency carrier 100 adopt have high reflectance and not the polycarbonate of extinction (Polycarbonate is called for short PC) material make.In addition, as shown in Figure 5 and Figure 6, the light tube group structure similar that adopts in light tube group 200 and the traditional backlight, it comprises printed circuit board (PCB) (PLCB) 201 and light emitting diode (LED) fluorescent tube 202 etc.
In addition, the backlight that provides in the present embodiment detects tool, to shown in Figure 9, can be provided with a plurality of grooves 101 as Fig. 5 on the transparency carrier 100, and light tube group 200 is arranged at the same side of a plurality of grooves 101.Transparency carrier 100 arranges a plurality of grooves 101, can carry out the assembly operation of each blooming piece of a plurality of backlights simultaneously.What certainly can understand is that in actual applications, the backlight that provides for the utility model detects second kind of embodiment of tool as shown in figure 10.As shown in figure 10, also a groove 101 can only be set on the transparency carrier 100.
In addition, need to prove, as Fig. 5 to shown in Figure 9, light tube group 200(lamp bar) only be arranged at a side of groove 101, should be understood that in actual applications, light tube group 200(lamp bar) can be provided with a plurality of, be arranged at groove 101 around.
In addition, the backlight that provides in the present embodiment detects tool, as shown in Figure 5 and Figure 6, be positioned at the zone of groove 101 peripheries and the side surface of transparency carrier 100 all is coated with anti-dazzling screen 500 first of transparency carrier 100, be used for reducing the light losing that light source sends.In the present embodiment, reflector plate 300 plays the effect of the light that reflection source sends, and anti-dazzling screen 500 plays and reduces the light losing effect that light source sends, thereby, finally in groove 101, reach spotlight effect.
The backlight that provides in the present embodiment detects tool, and is preferred, is positioned at the side surface Continuous pressing device for stereo-pattern of the zone of groove 101 peripheries and transparency carrier 100 to form described anti-dazzling screen 500 first of transparency carrier 100.Should be understood that in actual applications, anti-dazzling screen 500 also can adopt other modes to form.
In addition, the backlight that provides in the present embodiment detects tool, preferably, the adhesive tape that forms anti-dazzling screen 500 adopts the black and white adhesive tape, and the black and white adhesive tape has relative white and pastes face and black outside surface, and white stickup face is pasted fixing with transparency carrier 100, thereby it is less that white stickup face absorbs light source, and black outside surface good shading effect, thereby, reduce loss of light source.Certainly, in actual applications, adhesive tape also can be selected black adhesive tape for use.
In addition, need to prove that as shown in Figure 6, the edge of reflector plate 300 is pasted fixing by the edge of anti-dazzling screen and transparency carrier 100.Because reflector plate 300 itself is light tight substantially, therefore, the exposed surface of reflector plate 300 is masking tape not, reduces cost.Certainly, in actual applications, also can adopt adhesive tape that the exposed surface of reflector plate 300 and transparency carrier 100 is all covered.
The backlight that provides in the present embodiment detects tool, and is preferred, can be at the edge of reflector plate 300 Continuous pressing device for stereo-pattern to form described anti-dazzling screen 500.Should be understood that in actual applications, anti-dazzling screen 500 also can adopt other modes to form.
In addition, the backlight that provides in the present embodiment detects tool, preferably, the adhesive tape that forms anti-dazzling screen 500 adopts the black and white adhesive tape, and the black and white adhesive tape has relative white and pastes face and black outside surface, and white stickup face is pasted fixing with transparency carrier 100, thereby it is less that white stickup face absorbs light source, and black outside surface good shading effect, thereby, reduce loss of light source.Certainly, in actual applications, adhesive tape also can be selected black adhesive tape for use.
In addition, also need to prove, the backlight that provides in the present embodiment detects tool, when the backlight for double-screen liquid-crystal display device detects, it is mainly used in the detection of each blooming piece of secondary screen back light source part, each blooming piece of secondary screen back light source part can be carried out assembly in groove 101, backlight for the pair screen provides light source thus, to find the bad of secondary screen, what certainly can understand is that the backlight that provides in the present embodiment detects tool, is not limited to the detection of secondary screen back light source, in application, also liquid crystal panel or other modules can be placed in the groove 101 according to demand and detect.
It more than is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
