Abstract

The invention discloses a backlight module. The backlight module comprises a backboard, an optical diaphragm, at least one light source and at least one clamping assembly. The optical diaphragm is configured on the backboard. The light source is configured between the backboard and the optical diaphragm. The clamping assembly comprises a clamping structure and an elastic part. The clamping structure is configured on the backboard. One end part of the optical diaphragm is clamped in the clamping structure. The elastic part is configured between the clamping structure and the backboard. The clamping structure applies pulling force on the optical diaphragm through elastic force provided by the elastic part. The backlight module has following beneficial effects: without additional configuration of a dispersion board, the optical diaphragm is supported, thereby saving manufacture cost and assembly procedures of the backlight module.

Description

technical field [0001] The invention relates to an optical module, and in particular to a backlight module. Background technique [0002] With the increasing development of the semiconductor industry and related electronic industries, digital display devices such as smart phones (smart phones), notebook computers (notebooks), tablet PCs (tablet PCs), and flat-screen TVs are all developing in the direction of more convenience, multi-function and beauty. . When using these products, the display screen is an indispensable interface, and liquid crystal display devices (liquid crystal display, LCD) have become the mainstream of the display screen. [0003] Since the liquid crystal panel of the liquid crystal display device does not emit light, a backlight module (backlight module) must be provided under the liquid crystal panel to provide the required light for displaying images. For a direct type backlight module, generally, a diffuser plate and an optical film are arranged on...
