Problems solved by technology

[0005] However, when the backlight module is used, the optical film is prone to bending due to the heat of the backlight or its own weight, especially for large-sized backlight modules, it is easier to produce bending due to its own weight situation, thereby affecting the optical improvement effect of the optical film, and then affecting the backlight efficiency of the entire backlight module

Embodiment Construction

[0030] Please refer to FIG. 1, which is a schematic cross-sectional view of the backlight module and the liquid crystal display module according to the first embodiment of the present invention. The backlight module 100 of this embodiment is preferably a direct type backlight module, which is arranged under a liquid crystal display module 200 to form a liquid crystal display (LCD). The backlight module 100 includes a backlight source 110, at least one optical film 120 and at least one supporting structure 130. The optical film 120 is arranged above the backlight source 110, and the supporting structure 130 is arranged on the backlight source 110 to support the optical film 120 on the backlight source 110 to prevent the optical film 120 from being deflected by itself. Affect the overall backlight effect.

[0031] The backlight source 110 of this embodiment may be, for example, a cold cathode fluorescent lamp (Cold Cathode Fluorescent Lamp; CCFL), a hot cathode fluorescent lamp (Hot...

Abstract

The invention relates to a backlight module and an application thereof, wherein the backlight module at least comprises a backlight source, at least one optical film and at least one support structure, wherein the optical film is provided above the backlight source, the support structure is provided on the backlight source for supporting the optical film on the backlight source. The backlight module can be applied in liquid crystal display devices.

Description

Technical field [0001] The invention relates to a backlight module and its application, in particular to a backlight module which can avoid the bending of an optical film and its application on a display device. Background technique [0002] The information and communication industries continue to innovate, driving the vigorous development of the liquid crystal display (Liquid Crystal Display; LCD) market. Liquid crystal displays have the advantages of high image quality, small size, light weight, low drive voltage and low power consumption, so they are widely used in personal digital assistants (Personal Digital Assistant; PDA), mobile phones, camcorders, notebook computers, Consumer communication or electronic products such as desktop monitors, car monitors, and projection TVs. At the same time, due to the rapid advancement of the integrated circuit (IC) industry and liquid crystal display manufacturing technology, these consumer communications or electronic products are also d...
