SUMMERY OF THE UTILITY MODEL

To solve the problems set forth in the background art described above. The utility model provides a jumbo size highlight screen TV light guide plate has solved the problem that luminance can not keep in certain extent always when using.

In order to achieve the above object, the utility model provides a following technical scheme: a large-size high-brightness screen TV light guide plate comprises a light guide plate body, wherein an irradiation light source is arranged on one side of the light guide plate body, an irradiation layer is arranged on the inner side, extending to the light guide plate body, of one side of the irradiation light source, and a light emergent face is arranged at the top of the irradiation layer.

Preferably, a dot layer is arranged on the inner side of the irradiation layer, and a reflection surface is arranged at the bottom of the irradiation layer.

Preferably, a reflective layer is arranged at the bottom of the dot layer.

Preferably, a brightness enhancing layer is disposed on top of the reflective layer.

Preferably, the bottom of the brightness enhancing layer is provided with a protective layer.

Compared with the prior art, the beneficial effects of the utility model are that:

conveniently when providing the light source for the light guide plate originally internally at the illuminant through the blast layer that sets up, increase the luminance of shining the intraformational light source, the convenience is when the light source with illuminant department shines on the light guide plate body, with the external reflection of light through the light guide plate body, thereby increase the luminance of light, thereby when using the light guide plate body, the condition of darkness can not appear in the luminance of light guide plate body department, conveniently improve the luminance of light guide plate body department reverberation when using, increase the brightness of watching the in-process, the reduction is watched through the light guide plate can not be fine.
