Problems solved by technology

However, this design tends to increase the overall manufacturing cost
In addition, although the added flat panel has light transmittance, when the light transmittance cannot reach 100%, the overall luminance of the backlight module often decreases.
Adding a flat panel will also increase the weight of the backlight module, thereby affecting the weight of the final product

Embodiment Construction

[0038] The invention provides a diaphragm suspension system and a diaphragm suspension device used therefor. The film preferably includes various optical films, such as a diffusion film, a brightness enhancement film, and a reflection film. In addition, the diaphragm may also include other sheet-shaped or plate-shaped optical elements, such as light guide plates. In a preferred embodiment, the film suspension system of the present invention is used for liquid crystal display devices and their backlight modules; however, in different embodiments, the backlight module containing the film suspension system of the present invention can also be used for computer keyboards, Mobile phone buttons, billboards and other devices that require flat light sources. Furthermore, the present invention also includes a liquid crystal display device using the membrane suspension system. In a preferred embodiment, the liquid crystal display device of the present invention includes a color liquid...

Abstract

A diaphragm suspension system comprises support body, diaphragm suspension device and diaphragm. The said diaphragm suspension device is formed by support connection unit, elastic element and diaphragm connection unit.

Description

technical field [0001] The present invention relates to a film suspension system and a film suspension device used therein; in particular, to a film suspension system for a backlight module and a film suspension device used therefor. Background technique [0002] Backlight modules are widely used in liquid crystal display devices, computer keyboards, mobile phone keys, billboards and other devices that require light sources to provide planar light sources required by such devices. In particular, in recent years, the market demand for liquid crystal display devices has grown significantly. In order to meet the functional and appearance requirements of liquid crystal display devices, the designs of backlight modules used in liquid crystal display devices are also increasingly diversified. [0003] FIG. 1 is a schematic diagram of a conventional liquid crystal display device. As shown in FIG. 1 , the backlight module generally includes a light source module 70 , a reflector 90...
