Abstract
The utility model relates to a uniform light structure. A plurality of reflection parts for reflecting light rays emitted by a light emitting source to the direction of a panel assembly are distributed on a reflection plate of a backlight module. Each reflection part individually maintains distance with the light emitting source. The height of each reflection part is in direct proportion with the distance of the light emitting source, and adjacent reflection parts have established height fall. Thus, light rays emitted by the light emitting source from each angle can be uniformly emitted to the direction of the panel assembly via each reflection part distributed on the reflection plate and each position of the panel assembly displays uniform manifestation effect.
Description
Technical field
The utility model relates to the light emitting source reflection technology of module backlight, by at module backlight wherein the structure at reflector position improved, aim to provide one and can allow each position of panel assembly of module backlight present all light structure of uniform luminance expression effect.
Background technology
As shown in Figure 1, be for generally being applied in backlight liquid crystal display modular structure cut-open view, it is that avris at a panel assembly 10 is provided with at least one light emitting source 20 that the structure of whole module backlight is formed, and the outside mask at light emitting source 20 is provided with reflection shield 30, under the effect of reflection shield 30, make in the light of light emitting source 20 towards the irradiation of the inboard of panel assembly 10, especially whole module backlight is provided with a reflector 40 in the bottom position of panel assembly 10 in addition, reflect towards the direction of panel assembly 10 in the hope of the light that under the effect of reflector 40, each light emitting source 20 is shed, and to allow whole module backlight present due brightness expression effect.
Yet, the aforementioned reflector 40 of commonly using module backlight is to be a flat plate body structure, the angle that sheds the light that adds light emitting source 20 differs, therefore also can't evenly penetrate as the light that expection allows light emitting source 20 be shed towards each position of panel assembly 10, the brightness that makes panel assembly 10 is only concentrated on specific position and becomes so-called bright rays, significantly influence the brightness expression effect of whole module backlight.
The utility model content
In view of this, all light structure of the utility model module backlight, promptly be laid with some reflecting parts in order to the light that light emitting source shed is reflected towards the panel assembly direction at the reflector position of module backlight, each reflecting part is indivedual and light emitting source is kept set spacing, the height of each reflecting part be with its under light emitting source distance be directly proportional, and adjacent reflecting part is to have set height fall, the light that can allow each angle of light emitting source shed is able to evenly penetrate towards the direction of panel assembly via each reflecting part that is distributed on the reflector, makes each position of panel assembly present uniform brightness expression effect.

Embodiment
The clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:
All light structure of the utility model module backlight, its what is called all structure of light structure is formed as shown in Figure 2, mainly be to be laid with some reflecting parts 50 that reflect towards panel assembly 10 directions in order to the light that light emitting source 20 is shed at reflector 40 positions of module backlight, each reflecting part 50 is indivedual and light emitting source 20 is kept set spacing, and the height of each reflecting part 50 be with its under light emitting source 20 distance be directly proportional, that is be to have set height fall between the adjacent reflecting part 50.
When implementing, whole module backlight is that the avris at a panel assembly 10 is provided with at least one light emitting source 20 basically, and the outside mask at light emitting source 20 is provided with reflection shield 30, seeing through reflection shield 30 will shine towards the inboard of panel assembly 10 in the light of light emitting source 20, whole module backlight is provided with a reflector 40 in the bottom position of panel assembly 10 in addition, reflect towards the direction of panel assembly 10 in the hope of the light that under the effect of reflector 40, each light emitting source 20 is shed, allow whole module backlight present due brightness expression effect.
Especially, when reflection shield 30 with the light of light emitting source 20 in during towards the irradiation of the inboard of panel assembly 10, the light that light emitting source 20 each angle shed is able to evenly penetrate towards the direction of panel assembly 10 via each reflecting part 50 that is distributed in reflector 40 positions, makes each position of panel assembly 10 present uniform brightness expression effect.
Moreover, all light of the present utility model structure in the specific implementation, each reflecting part 50 is to be the single structure body on the reflector 40 of being installed in as shown in Figure 2; Certainly, can also be as shown in Figure 3, each reflector 40 is designed to be integrally formed with the structural feature of each reflecting part 50, and reflector 40 is to form hollow form with each reflecting part 50, evenly penetrate and all possess, make each position of panel assembly 10 present the function of uniform luminance expression effect towards the direction of panel assembly 10 just like the preceding described light that light emitting source 20 all angles can be shed.
As mentioned above, the utility model provides module backlight a kind of preferable feasible all light structure, so, offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be one of the utility model preferred embodiment, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc. such as, identical, all should belong within creation purpose of the present utility model and the claim.
Claims (4)
