Definitions
- the light guide plate 01 and the bottom reflector 02 are assembled by superposition, and the thickness between the light guide plate 01 and the bottom reflector 02 may be Micron-sized air interlayer 03; since the refractive index n2 of air is n1, and the refractive index n1 of the light guide plate 01 is 1.5, when the light emitted from the backlight 04 reaches the contact interface between the two, the whole occurs.
- the reflection phenomenon is performed to realize the transmission of light inside the light guide plate 01; and the light is scattered by the halftone dots 05 on the light guide plate 01 and then emitted from the front surface of the light guide plate 01, thereby realizing the conversion of the light propagation direction.
- the transparent material layer has a refractive index of less than 1.2.
- the transparent material layer has a thickness of from 100 nm to 5 ⁇ m.
