Problems solved by technology

[0007] Second, the present invention solves the problem of film displacement and deformation of the multilayer optical diaphragm: the fixed glue applied between the multilayer optical diaphragm will deform the optical diaphragm itself under the high temperature and high pressure conditions in the test procedure, Then produce displacements of varying degrees, and through the fixed structure of the front light and backlight film group of the present invention, since no adhesive material is used, the problem of film displacement and deformation of the multilayer optical film does not occur

Abstract

A fixing structure of front-light and back-light film set has a liquid crystal light valve and a lighting unit for lighting said LC light valve. It features that at least one film is fixed between baseplate and light source in non-adhering mode. In the following test process, the reliability of said film is not affected by high temp.

Description

technical field [0001] The present invention proposes a simple, fast and effective fixing structure for the front light and backlight film group, which is mainly used for fixing the front light and backlight optical film group, and can solve the most popular applications in the photoelectric industry at present, such as liquid crystal displays etc., the multilayer optical film is reworked twice or multiple times, and there is no problem of residual glue left, and the multilayer optical film will not have the problem of deterioration due to heat of the glue. Background technique [0002] The reflective liquid crystal display and miniature information electronic products in the Japanese patent announcement No. 21883 / 2001 published on January 26, 2001 mainly explain the thin and lightweight realization method of the reflective liquid crystal display. Between the opposite glass substrates, there are polarizing plates, phase difference plates, diffusion plates, color films, trans...
