A light guide plate capable of reducing viewing angle and improving brightness, a mold and a striker

Abstract

The utility model discloses a light guide plate and mould, striker that can reduce visual angle and improve luminance relates to light guide plate technical field. The utility model discloses a light guide plate's upside is the light exit surface, and the light guide plate's downside is the microstructure surface, and the light guide plate's one end side is the light entrance surface, and the light entrance surface is perpendicular with the light exit surface, the microstructure surface respectively, the light guide plate's light exit surface is above interval and is equipped with a plurality of parallel 'V' shape groove, and 'V' shape groove is parallel with the light entrance surface, and the light guide plate's microstructure surface is above evenly and is arranged with a plurality of microstructure convex, and microstructure convex is the pentahedron convex. The utility model discloses a light guide plate can improve luminance through 'V' shape groove and microstructure convex, and two isosceles trapezoidal surface and two isosceles triangle surface on the pentahedron convex can gather light from all around to the middle, make the light guide plate's luminance improve greatly, and make visual angle reduce to 100 degrees below, satisfy the demand of user protection privacy, prevent the peeping.
