Abstract

A light guide plate template which comprises a frame and a plurality of light guide plate building blocks which are arranged in the frame to form an integral light guide plate, each of the light guide plate building blocks has dots on its bottom surface to make it have a predetermined light-emitting efficiency.

Claims (16)

1. A method of manufacturing a light guide plate template, comprising the following steps:

manufacturing a plurality of light guide plate building blocks each having a different predetermined light-emitting efficiency level, wherein the different predetermined light-emitting efficiency levels are divided by an interval;

selecting a plurality of light guide plate building blocks from the plurality of light guide plate building blocks each having the different predetermined light-emitting efficiency level and arranging the selected plurality of the light guide plate building blocks in a frame to form a test light guide plate based on optical simulation results and the predetermined light-emitting efficiency of the plurality of light guide plate building blocks; and

performing an optical test on the test light guide plate and adjusting arrangement of the building blocks in the test light guide plate by comparing results of the optical test with predetermined design requirements on the light guide plate template so as to form the light guide plate template.

2. The method to claim 1 , wherein manufacturing a plurality of light guide plate building blocks each having a predetermined light-emitting efficiency comprises the following steps:

manufacturing a plurality of light guide plate blocks;

processing side surfaces of the plurality of light guide plate blocks; and

printing dots on a bottom surface of the light guide plate blocks with the processed side surfaces.

3. The method according to claim 1 , wherein performing an optical test on the test light guide plate and forming a light guide plate template comprise the following steps:

step ( 201 ) of performing an optical test on the test light guide plate to obtain test results;

step ( 202 )of determining if the test light guide plate meets the predetermined design requirements according to the test results, wherein if the test light guide plate meets the design requirements, the step ( 204 ) is performed, otherwise step ( 203 ) is performed;

step ( 203 ) of finding out and replacing the light guide plate building block with local brightness abnormality on the test light guide, and then performing step ( 201 ) again; and

step ( 204 ) of forming a light guide plate template on the basis of the test light guide plate which meets the design requirements.

4. The method according to claim 2 , wherein the plurality of light guide plate building blocks having a width of about 1.0 cm and a length of about 1.0 cm.

5. The method according to claim 2 , wherein processing the side surfaces of the plurality of light guide plate blocks comprises polishing and grinding the side surfaces of the plurality of light guide plate blocks.

6. The method according to claim 3 , wherein forming a light guide plate template comprises employing a compensatory light transmittance factor to the test light guide plate.
