Description
Technical field
The present invention about a kind of backlight module, use the Liquid crystal disply device and its preparation method of this backlight module; Particularly, the present invention about a kind of backlight module with photoresistance next door, use the Liquid crystal disply device and its preparation method of this backlight module.
Background technology
Backlight module is widely used in liquid crystal indicator, computor-keyboard, mobile phone button, advertisement plate and other needs on the device of light source, to provide this type of device required planar light source.Particularly the market demand of liquid crystal indicator is significantly grown up in recent years, and for the fluid,matching crystal device reaches apparent requirement on function, the employed backlight module design of liquid crystal indicator also becomes more diversified.
With the liquid crystal indicator is example, and for quality and the processing speed that improves dynamic image, the backlight module of liquid crystal indicator has been introduced the technology of dynamic area light modulation.As shown in Figure 1, use in the backlight module 10 of dynamic area light regulating technology, on base plate 11, be equipped with barrier structure 30.Barrier structure 30 is isolated into several blocks 20 with backlight module 10; Then be provided with several light sources 21 in each block 20.By the setting of barrier structure 30, system can adjust the brightness of each block 20 respectively and reduce interference to adjacent block 20 brightness.
Yet in this design, as shown in Figure 1 because barrier structure 30 has certain thickness, thus the light that sends in the position of barrier structure 30 of backlight module 10 a little less than.In other words, the image that display panel produces corresponding to place, barrier structure 30 position easily has blanking bar to produce, and influences the quality of overall image.
Summary of the invention
A purpose of the present invention is to provide a kind of backlight module and manufacture method thereof, can reduce the situation that produces the light blanking bar.
A purpose of the present invention is to provide a kind of backlight module and manufacture method thereof, can be applied to respectively on the liquid crystal indicator of dynamic area light modulation or scan-type.
Another object of the present invention is to provide a kind of liquid crystal indicator, the image that can avoid producing has blanking bar.
Liquid crystal indicator comprises display panel and backlight module.Display panel is arranged at the backlight module top; After the light that backlight module penetrates enters display panel, show image through the liquid crystal layer of display panel and on display surface.Backlight module includes base plate, a plurality of light sources and at least one photoresistance next door.Base plate has a plurality of light-emitting zones; Light sources then is arranged at respectively on each light-emitting zone.The photoresistance next door is arranged on the base plate, and lays respectively between the adjacent light-emitting zone.
The photoresistance next door includes the first printing opacity supporting walls, second printing opacity supporting walls and the reflection layer.The first printing opacity supporting walls is arranged on the base plate, and has the wall that stands on base plate.This second printing opacity supporting walls and this first printing opacity supporting walls are arranged side by side.Reflection layer is formed on the wall of the first printing opacity supporting walls, and this reflection layer is located between this first printing opacity supporting walls and this second printing opacity supporting walls.Because the support of the first printing opacity supporting walls and wall, reflection layer is stood on the base plate.
Backlight module manufacture method provided by the invention comprises the following step: form a plurality of light-emitting zones on base plate; A plurality of light sources are set respectively on light-emitting zone; On the wall of the first printing opacity supporting walls, form reflection layer to form the photoresistance next door; And the photoresistance next door being set between adjacent light-emitting zone, the step that wherein forms this photoresistance next door comprises folder and establishes this reflection layer between this first printing opacity supporting walls and one second printing opacity supporting walls.
According to such scheme, the present invention is significant with respect to the effect of prior art: the present invention is by the setting of reflection layer, the light that adjacent two light-emitting zones are sent is partly or entirely intercepted and is reflected, and then reaches the effect of subregion control backlight illumination.In addition because reflection layer and the first printing opacity supporting walls be equipped with, and mainly by the first printing opacity supporting walls as the structure that supports, so the thickness of reflection layer can reduce relatively, with minimizing because of the issuable light blanking bar of thickness.Because of the first printing opacity supporting walls has the characteristic of printing opacity, so its thickness is difficult for making the generation blanking bar backlight that outwards sends.
