Abstract

The invention discloses a backlight module for a liquid crystal display device. The backlight module comprises a light source, a rear panel, a light-guiding plate and an optical diaphragm, wherein the light source is used for emitting light; the rear panel is provided with a loading surface and at least one lateral edge; the rear panel is used for loading the light source through the loading surface; the light-guiding plate is located on the light source and is used for guiding the light; the optical diaphragm is used for processing the light after being guided by the light-guiding plate; the optical diaphragm is located on the light-guiding plate and is provided with at least one bending part; and the bending part is connected with the lateral edge of the rear panel, so as to fix the relative position of the optical diaphragm.

Description

technical field [0001] The present invention relates to a backlight module and its related liquid crystal display device, in particular to a backlight module which can have a narrow frame and its related liquid crystal display device. Background technique [0002] Liquid Crystal Displays (LCDs) are widely used in modern information devices such as computers, mobile phones, and personal digital assistants due to their lightness, thinness, and low power consumption. Generally speaking, a liquid crystal display includes a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not emit light, the liquid crystal display must rely on a light source in the backlight module to emit light. The light emitted by the light source in the backlight module passes through the liquid crystal of the liquid crystal display panel, and the intensity of the light transmitted to the user is adjusted by the turning of the liquid crystal to output an ...
