Abstract

This invention relates to a manufacturing method of light conducting board including steps that follows: first to provide a thin film with a transfer- printing material coat, and then to provide a light conductive plate shaper with nest in, later to locate a thin film in the shaper and locate part of transfer-printing material in the nest, finally to put a forming light conductive plate in the module nest. The above transfer-printing material coat is in the light conductive plate. The preparation method of light conductive plate in this method can improve the replicability of the light conductive plate and reduce the thickness of the plate and decrease the possibility of light leaking of the plate.

Description

technical field

[0001] The present invention relates to a light guide and a manufacturing method thereof, in particular to a light guide using transfer printing technology and a manufacturing method thereof. Background technique

[0002] The rapid progress of the multimedia society is mostly due to the rapid progress of semiconductor components or man-machine display devices. As far as the display is concerned, the cathode ray tube (Cathode Ray Tube, CRT) has been monopolizing the display market in recent years due to its excellent display quality and economy. However, for the environment where most of the personal operations are terminals / display devices, if we cut in from the viewpoint of environmental protection, or predict the trend of saving energy, there are still many problems in the use of space and energy consumption of cathode ray tubes. However, there is no effective solution to the requirements of lightness, thinness, shortness, smallness and low power consumpti...
