Abstract
The invention discloses a back plate of an improved backlight unit. The back plate of the improved backlight unit comprises a bottom layer and a high-reflection layer arranged on the bottom layer, wherein the bottom layer is an acrylonitrile butadiene styrene (ABS) plastic layer, the high-reflection layer is a poly carbonate (PC) plastic layer, and reflection particles accounts 10-30wt% of PC plastic. Because the high-reflection layer is arranged on the ABS plastic layer, and the high-reflection layer is the PC plastic layer with the reflection particles mixed, when light of a backlight source of the backlight unit is transmitted on the back plate, light waves can be transmitted into the high-reflection layer through transparent characteristics of the PC plastic, and light reflection and diffusion characteristics of the reflection particles inside the high-reflection layer are utilized to reflect out light waves in the high-reflection layer to ensure that the back plate is provided with reflective effect without additionally arranging a reflective sheet, and the problem that because reflective sheets are additionally arranged on the original back plate, installment procedures of the backlight unit are trial and work load of workers is increased is avoided.
Description
Technical field
The present invention relates to a kind of backlight module, particularly a kind of backboard of backlight module.
Background technology
Backlight module is one of key part and component of panel of LCD, and because liquid crystal itself is not luminous, the function of backlight module namely is well-off brightness and the light source that is evenly distributed, normally show image.existing backlight module mainly comprises: backboard, LGP and backlight, its dorsulum is mostly worked as part outward appearance and protection backlight, the assembly effects such as LGP, generally to adopt commaterial to be made, as adopt lower-cost plastics (as ABS plastic) to make, yet, this kind backboard not only can't reach reflecting effect for light, can cause the loss of optical energy on the contrary, therefore must make up the optical loss that backboard causes by reflector plate, have more when mounted the operation that reflector plate is installed at the backboard medial surface together, make the installation procedure of backlight module comparatively numerous tired, and increased workman's the amount of labour.
In view of above-mentioned reason, the inventor furthers investigate the structure of the backboard of backlight module, is then produced by this case.
Summary of the invention
The purpose of this invention is to provide a kind of backboard of modified backlight module, it has reflecting effect to light, need not to set up reflector plate, has avoided traditional backboard to cause the numerous problem of being tired of and increasing workman's amount of labour of backlight module installation procedure because setting up reflector plate.
Technical scheme of the present invention is such: a kind of backboard of modified backlight module, comprise bottom and the high reflection layer of being located on bottom, above-mentioned bottom is the ABS plastic layer, above-mentioned high reflection layer has the PC of reflective particle plastic layer for mixing in it, and above-mentioned reflective particle accounts for the 10%-30% of above-mentioned PC plastics gross weight.
Above-mentioned reflective particle is a kind of in Titanium particles and barium sulfate particle.
The thickness of above-mentioned high reflection layer is 100-350um.
Above-mentioned bottom and above-mentioned high reflection layer are combined with each other by high-temperature heating.
after adopting technique scheme, the backboard of a modification of the present invention type backlight module, owing to being located at high reflection layer on the ABS plastic layer, and high reflection layer has the PC of reflective particle plastic layer for mixing in it, like this, when the light of backlight module backlight is injected when being incident upon backboard, transparent characteristic by the PC plastics can be incident upon this light wave in high reflection layer, and utilize high reflection layer internal reflection particle the light wave reflection in high reflection layer can be gone out to the characteristic of reflection of light and diffusion, make backboard have reflecting effect to light, need not separately to set up a reflector plate, avoided traditional backboard to cause the numerous problem of being tired of and increasing workman's amount of labour of backlight module installation procedure because setting up reflector plate.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the optical effect figure of high reflection layer in the present invention.
In figure:
Bottom 1 high reflection layer 2
Reflective particle 3
The specific embodiment
The backboard of a modification of the present invention type backlight module, as shown in Figure 1, 2, comprise bottom 1 and the high reflection layer 2 of being located on bottom 1, this bottom 1 is the ABS plastic layer, this high reflection layer 2 has the PC of reflective particle 3 plastic layer for mixing in it, this bottom 1 is combined with each other by high-temperature heating with high reflection layer 2, the thickness of this high reflection layer 2 is 100-350um, this reflective particle 3 is a kind of in Titanium particles and barium sulfate particle, and the gross weight of reflective particle 2 accounts for the 10%-30% of PC plastics gross weight.
the backboard of a modification of the present invention type backlight module, due to a compound high reflection layer 2 on original ABS plastic backboard, and high reflection layer 2 has the PC of reflective particle 3 plastic layer for mixing in it, during use, high reflection layer 2 is used as the medial surface of backboard, like this when the light of backlight module backlight is injected the medial surface that is incident upon backboard, transparent characteristic by the PC plastics can be incident upon this light wave in high reflection layer 2, and utilize the characteristic of 3 pairs of reflection of lights of high reflection layer 2 internal reflection particle and diffusion the light wave reflection in high reflection layer 2 can be gone out, make backboard have reflecting effect to light, need not separately to set up a reflector plate, avoided traditional backboard to cause the numerous problem of being tired of and increasing workman's amount of labour of backlight module installation procedure because setting up reflector plate.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present invention to its suitable variation or modification of doing.
Claims (4)
1. the backboard of a modified backlight module, it is characterized in that: comprise bottom and the high reflection layer of being located on bottom, above-mentioned bottom is the ABS plastic layer, and above-mentioned high reflection layer has the PC of reflective particle plastic layer for mixing in it, and above-mentioned reflective particle accounts for the 10%-30% of above-mentioned PC plastics gross weight.
