Abstract

The invention discloses a backlight module and a liquid crystal display comprising the backlight module. The backlight module at least comprises a backboard, at least one light source, at least two supporting frameworks and at least one optical film, wherein the backboard at least comprises a base plate and a plurality of lateral plates surrounding the edge of the base plate; at least one light source is arranged on the backboard; at least two supporting frameworks are arranged on two relative sides of the backboard respectively; at least one optical film is arranged on the light source, and the optical film is provided with at least two fixed hole respectively corresponding to the supporting frameworks; and the supporting frameworks are inserted into the fixed holes respectively so as toprovide at least one pair of tensile force for the optical film.

Description

technical field [0001] The invention relates to a display device, and in particular to a backlight module and a liquid crystal display including the same. Background technique [0002] In the current liquid crystal display device, in order to improve the optical quality of the display area, such as improving the brightness and brightness uniformity, an optical film group is usually arranged in the backlight module. When the optical film set is applied to a direct-lit backlight module, the optical film is usually placed directly on the diffuser plate; and when the optical film set is applied to a side-lit backlight module, it is usually placed directly on the light guide plate. [0003] For example, please refer to FIG. 1 , which is a partial cross-sectional schematic view of a conventional liquid crystal display. The liquid crystal display 100 is mainly composed of a direct type backlight module 104 and a liquid crystal display panel 102 , wherein the backlight module 104 i...
