1. A finger board for a finger to press, comprising:
- a board layer with a first refractive index comprising a first board surface and a second board surface opposite to each other, wherein the first board surface is for the finger to press; and
a micro-structure layer with a second refractive index different from the first refractive index being disposed on the second board surface,wherein after a light ray is emitted in the micro-structure layer, the light ray is refracted between the micro-structure layer and the board layer, reflected and scattered on the first board surface, refracted again between the micro-structure layer and the board layer, and then emitted out of the micro-structure layer.

Abstract
A finger board for a finger to press including a board layer and a micro-structure layer is disclosed. The board layer has a first refractive index, and has a first board surface and a second board surface opposite to each other. The first board surface is used for the finger to press. The micro-structure layer has a second refractive index different from the first refractive index, and is disposed on the second board surface. Therefore, a light ray emitted from the micro-structure layer to the first board surface can be reflected and scattered on the first board surface, so as to uniformly distribute energy.

5. A finger board, applied for a finger to press, comprising:
-
a board layer with a first refractive index comprising a first board surface and a second board surface opposite to each other, wherein the first board surface is for the finger to press; a micro-structure layer with a second refractive index different from the first refractive index being disposed at one side of the board layer having the second board surface; a medium layer with a third refractive index different from the first refractive index and the second refractive index being located between the micro-structure layer and the board layer; and an adhesion layer with a fourth refractive index different from the first refractive index, the second refractive index, and the third refractive index being located between the medium layer and the board layer, wherein after a light ray is projected in the micro-structure layer, the light ray is refracted between the micro-structure layer and the medium layer, between the medium layer and the adhesion layer, and between the adhesion layer and the board layer in turn, then reflected and scattered on the first board surface, then refracted between the board layer and the adhesion layer, between the adhesion layer and the medium layer, and between the medium layer and the micro-structure layer in turn, and then emitted out of the micro-structure layer. - View Dependent Claims (6, 7, 8, 9, 10)
