Display apparatus and light emitting module thereof

摘要

A display apparatus comprising a display panel and a light emitting module disposed oppositely is provided. The light emitting module comprises a light guide plate, a plurality of light guide grooves and at least a light unit. The light guide plate has at least a light incident surface, a first surface and a second surface opposite to the first I surface. The light guide grooves are disposed on the first surface. Each light guide groove has a bottom, which is the portion of each light guide groove closest to the second surface, wherein the larger the distance from the bottom to the closest light unit, the smaller the distance from the bottom to the second surface.

1. A light emitting module, comprising:
a light guide plate having a first light incident surface, a second light incident surface, a first surface and a second surface, wherein the first light incident surface is opposite to the second light incident surface, and the first surface is opposite to the second surface; at least two light units; and a plurality of light guide grooves each being disposed on the first surface at an interval and having a bottom being the portion of each light guide groove closest to the second surface, wherein after the light emitted from the light unit enters the light guide plate, the light is guided by the light guide grooves to be emitted off the second surface of the light guide plate; wherein, the light guide plate has the two light units respectively on each of the first light incident surface and the second light incident surface, and the distance from each bottom to the second surface is determined by following equation: y′=D−(ax2+bx+c), wherein the unit of x, y′ and D is μm, x denotes the smallest distance from the bottom of the light guide plate to the first light incident surface and 0
