Abstract

The invention is a backlight module, comprising frame, light reflecting adhesive tape, fixing adhesive tape, reflecting plate, light guide plate and at least a light source device, where one side of the frame has groove; the light reflecting adhesive tape is arranged in the groove; the fixing adhesive tape is arranged on the side of the frame and located on the light reflecting adhesive tape; the reflecting plate is arranged in the frame and is a gap apart from the fixing adhesive tape, and the gap is above the light reflecting adhesive tape; the light guide plate is arraged in the frame and located on the reflecting plate and the fixing adhesive tape and has at least a light incoming surface; and the light source device is arranged by the light incoming surface. And the backlight module can provide uniform plane light source.

Description

technical field [0001] The present invention relates to a backlight module and a liquid crystal display (LCD), and in particular to a backlight module capable of providing a uniform planar light source and a liquid crystal display using the backlight module. Background technique [0002] With the advancement of modern video technology, video devices are gradually trending toward light weight, large size, and thin panels. The flat panel display (FlatPanel Display), such as liquid crystal display (LCD), organic electro-luminescence display (Organic Electro-Luminescence Display, OLED) or plasma display (Plasma DisplayPanel, PDP), which is developed in conjunction with optoelectronic and semiconductor manufacturing technologies, has gradually become a The mainstream of display products. In recent years, most of the display screens on mobile phones, digital cameras, digital video cameras, notebook computers and desktop computers are based on liquid crystal display panels (LCD Pa...
