Modularized production method of optical part for liquid crystal display television and structure thereof

Abstract

The invention provides a modularized production method of an optical part for a liquid crystal display television and a structure thereof. The method comprises the following steps: stacking a lower diffusion film, an incremental film and an upper diffusion film from bottom to top to form an optical film layer; sewing the edge of one edge of a reflecting film with the edge of one edge of the optical film layer; and hanging the sewed reflecting film and optical film layer on a light guide plate, so that the reflecting film and the optical film layer are respectively positioned on two sides of the light guide plate. The light guide plate, a reflecting sheet and a optical diaphragm can form a closed module, so that a complex fixed structure in the television shell is avoided, the structural space is optimized, the interval time between step-by-step assembly is avoided, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal TV parts, in particular to a modular production method and structure of optical parts for liquid crystal TVs. Background technique [0002] The backlight module is one of the key components of the LCD panel. Its function is to supply sufficient brightness and evenly distributed light sources so that the LCD can display images normally. A light source, a light guide plate, a reflector, and an optical film constitute a backlight module of a liquid crystal display. When the light from the light source hits the liquid crystal panel, the light will pass through the lower polarizer first, and different liquid crystal panels will change the polarization direction of the light according to their own mechanism at this time. Next, the light hits the color filter to produce color, and finally enters the upper polarizer. After the polarization direction is changed by the liquid crystal, some light can go out, ...

AI Technical Summary

Problems solved by technology

[0003] In the current backlight module, the light guide plate, reflector and optical film are all bonded layer by layer in the process of assembling the module, or installed layer by layer on the casing of the TV set. The step-by-step assembly on the TV casing makes the TV casing need to be fixed in position for the light guide plate, reflector, and optical film, so that a fixed structure needs to be added in the limited space of the TV casing, resulting in the internal structure of the TV casing. Complicated, at the same time, the assembly interval time is generated by step-by-step assembly, which wastes production time in the assembly process and reduces production efficiency
