Abstract
The present invention relates to a high-luminance light guide plate, which is a plate formed by a transparent resin of high refractive index, where one side of the light guide plate is a light incident surface while the surface of light guide plate is a light emitting surface and the back of the surface opposite to the light emitting surface is a reflecting surface. A plurality of cells are sunken on the reflecting surface to form a diffusion pattern and arranged on a plurality of rows parallel to the light incident surface, where the cells on each two adjacent rows are in staggered arrangement. Besides, the further away a cell from the light incident surface, the higher the cell distribution density. A cross section of each cell in the direction perpendicular to the light incident surface is in a shape of unbalanced triangle with the inclined surface adjacent to the light incident surface as a first surface and the vertical surface away from the light incident surface as a second surface, where the inclined angle between the first surface and the reflecting surface is 45 degrees and the angle between the second surface and the reflecting surface is 90 degrees. Thus, a high-luminance light guide plate is formed.
