Patent ID: 8876320

Claim:
A direct type backlight, comprising: light emitting bodies; a reflecting sheet disposed below the light emitting bodies; a back plate disposed below the reflecting sheet; and a diffusing plate disposed above the light emitting bodies, wherein the backlight further comprises a reflection-enhancing layer disposed between the diffusing plate and the light emitting bodies, and the reflection-enhancing layer has, on a side thereof facing the light emitting bodies, a reflectivity that is greater than a reflectivity of the diffusing plate and smaller than 1, wherein the reflection-enhancing layer is a transflective layer, wherein the transflective layer comprises a substrate having a transmissivity of greater than 0 and a surface coating partially coated on a surface of the substrate, and the reflectivity of the surface coating is greater than 0; and wherein the surface coating comprises coating microstructures that are spaced apart, and after the light emitted from the light emitting bodies reaches the coating microstructures, some of the light exits through the coating microstructures, and some of the light is reflected to the reflecting sheet by the coating microstructures.
