Embodiment Construction

[0025] see image 3 , is a three-dimensional exploded schematic diagram of a preferred embodiment of the liquid crystal display device of the present invention. The display device 20 includes a liquid crystal display panel 21 , an optical film set 23 , a backlight module 25 and a frame 27 . The optical film set 23 is interposed between the liquid crystal display panel 21 and the backlight module 25 , and the outer frame 27 accommodates and holds the liquid crystal display panel 21 , the optical film set 23 and the backlight module 25 .

[0026] The liquid crystal display panel 21 is a display terminal, which receives the light emitted from the backlight module 25 and controls the amount of light passing through the liquid crystal display panel 21 to display images.

[0027] The optical film set 23 is formed by stacking multiple optical films, which is used to improve the intensity and uniformity of light passing through the optical film set 23 . The optical film set 23 inclu...

Abstract

The invention relates to a backlight module and an LCD device adopting the backlight module. The backlight module comprises a reflecting cover having an accommodating space, a plurality of lighting tubes, a plurality of brackets and a plurality of elastic structures, wherein the brackets are pivotally connected with the reflecting cover; the plurality of lighting tubes are arranged in parallel and with spacing in the accommodating space; one end of each elastic structure is butted with the reflecting cover; the other end thereof is connected with the bracket. In the backlight module, the elastic structures can effectively avoid scuffing of optical masks due to fine-tuning and positioning and improve the yield rate for assembly. Furthermore, by reducing the concentration of stress caused by external impacts imposing overhigh pressure intensity on the set of optical masks, the elastic structures can effectively prevent the optical masks from being damaged and effectively improve the safety and the liability during transportation.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. Background technique [0002] With the development of digital technology, liquid crystal display products have been widely used in all aspects of daily life, and liquid crystal display products are constantly developing in the direction of lightness, thinness, shortness and fashion. Therefore, designers need to continuously develop more sophisticated liquid crystal display products to meet the needs of consumers. [0003] The current liquid crystal display products usually include a liquid crystal display panel and a backlight module, and the backlight module is used to provide the light required by the liquid crystal display panel. Liquid crystal display products use different forms of backlight modules according to their usage or size, such as: direct-type backlight modules or side-type backlight modules. [0004] However, since liquid crysta...
