Abstract

An apparatus for compensating an image of a display includes a light incident surface, a light emitting surface, and a plurality of light guiding channels. An area of the light emitting surface is greater than an area of the light incident surface. The plurality of light guiding channels are independent from each other, each light guiding channel extends from the light incident surface to the light emitting surface. A cross section area of the light guiding channel increases along a direction from the first light incident surface to the first light emitting surface. Light from the light incident surface is extended to the light emitting surface by the light guiding channels. The present invention further discloses a method for manufacturing the same.

First claim

What is claimed is:

1. An apparatus for compensating an image of a display, comprising:
a light incident surface;
a light emitting surface, an area of the light emitting surface being greater than an area of the light incident surface; and
a plurality of light guiding channels independent from each other, each light guiding channel extending from the light incident surface to the light emitting surface, a section area of the light guiding channel increasing along a direction from the first light incident surface to the first light emitting surface, and light from the light incident surface being transmitted and expanded to the light emitting surface by the light guiding channels, wherein the light emitting surface comprises two planar surfaces intersecting with each other, the two planar surfaces define a V-shaped groove, and a depth of the V-shaped groove decreases along a direction far away from the light incident surface.

2. The apparatus of claim 1 , wherein each light guiding channel is defined by a light guiding fiber extending from the light incident surface to the light emitting surface, and an area of the light guiding fiber on the light emitting surface is greater than an area of the light guiding fiber on the light incident surface.

3. The apparatus of claim 2 , wherein the light guiding fiber is an optical fiber having a hexagon section, an outline diameter is defined between opposite end points of the hexagon section of each optical fiber, and the outline diameter of each optical fiber gradually increases along the direction from light incident surface toward the light emitting surface.

4. The apparatus of claim 1 , wherein each of the light incident surface and the light emitting surface is a planar surface, and the light incident surface intersects with the light emitting surface.

5. The apparatus of claim 4 , further comprising an inclined surface connected between the light incident surface and the light emitting surface, wherein the inclined surface is a planar surface, and an angle formed by the inclined surface and the light incident surface is an obtuse angle.

6. The apparatus of claim 5 , wherein the obtuse angle is 135 degrees.

7. The apparatus of claim 5 , further comprising a support portion attached to the inclined surface.
