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 is independent from each other, each light guiding channel extends from the light incident surface to the light emitting surface, and 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. A method for manufacturing an image compensating apparatus, comprising:
providing a plurality of light guiding elements, each light guiding element defining a light guiding channel extending along a predetermined direction;
arranging the plurality of light guiding elements in a matrix to form a light guiding element; and
cutting the light guiding element along at least one cutting plane intersecting the predetermined direction to obtain a compensating portion of the image compensating apparatus, the compensating portion comprising a light incident surface and a light emitting surface, an area of the light emitting surface greater than an area of the light incident surface, and each light guiding channel extending from the light incident surface to the light emitting surface.

2. The method of claim 1 , wherein each light guiding element is a light guiding fiber, 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 method of claim 2 , wherein a cross section area of the light guiding fiber is maintained constant.

4. The method of claim 1 , wherein the step of arranging the plurality of light guiding elements in the matrix to form the light guiding element comprises:
arranging and attaching the plurality of light guiding elements into a plurality of light guiding films by adhering or lamination in high temperature; and
arranging and attaching the plurality of light guiding films to the light guiding element by adhering or lamination in high temperature.

5. The method of claim 4 , wherein the light guiding element is substantial a cuboid, the light guiding channel extending from a top surface of the cuboid to a bottom surface of the cuboid, and the predetermined direction perpendicular to the top surface and the bottom surface of the cuboid.

6. The method of claim 5 , wherein the at least one cutting plane comprises a first cutting plane and a second cutting plane, the first cutting plane defined by diagonal lines of a pair of symmetrical side surfaces of the light guiding element, the second cutting plane intersecting with the first cutting plane, the step of cutting the light guiding element along at least one cutting plane intersecting the predetermined direction to obtain the image compensating apparatus comprising
cutting the light guiding element along the first cutting plane to obtain a tri-prism light guiding element; and
cutting the tri-prism light guiding element along the second cutting plane to obtain the compensating portion of the image compensating apparatus.

7. The method of claim 4 , wherein the light guiding element comprises a top surface, a bottom surface, a front surface, a rear surface, and a pair of side surface, the top surface, the bottom surface, the front surface, and the rear surface are substantially rectangular, the pair of side surfaces are parallel to each other and substantially parallelogram, the predetermined direction are parallel to the front surface, the back surface, and the pair of side surface, the predetermined direction and the bottom surface define an acute angel.

8. The method of claim 7 , wherein the at least one cutting plane comprises a first cutting plane, the first cutting plane defined by diagonal lines of the pair of side surfaces of the light guiding element, the step of cutting the light guiding element along at least one cutting plane intersecting the predetermined direction to obtain the image compensating apparatus comprising:
cutting the light guiding element along the first cutting plane to obtain the compensating portion of the image compensating apparatus.

9. The method of claim 7 , wherein each of the light incident surface and the light emitting surface is a planar surface, the light incident surface intersects with the light emitting surface, and the compensating portion further comprises an inclined surface connected between the light incident surface and the light emitting surface.

10. The method of claim 9 , further comprising:
attaching a support portion to the inclined surface to support the compensating portion.

11. The method 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.

12. A method for manufacturing a display, comprising:
providing a plurality of light guiding elements, each light guiding element defining a light guiding channel extending along a predetermined direction;
arranging the plurality of light guiding elements in a matrix to form a light guiding element;
cutting the light guiding element along at least one cutting plane intersecting the predetermined direction to obtain a compensating portion of the image compensating apparatus, the compensating portion comprising a light incident surface and a light emitting surface, an area of the light emitting surface greater than an area of the light incident surface, and each light guiding channel extending from the light incident surface to the light emitting surface; and
positioning the compensating portion of an image compensating apparatus adjacent and corresponding to a periphery display region of the display.
