Abstract

The invention provides a backlight module. The backlight module comprises a backboard, a film piece set, a first reflection piece and a backlight source. The first reflection piece is provided with afirst reflection piece. The backboard, the film piece set and the first reflection piece enclose a reflection cavity, and the backlight source is placed in the reflection cavity. By additionally arranging the reflection piece and the reflection surface on the backlight module, the reflection cavity is formed, the light emitting direction and light emitting route of the backlight source are changed, therefore the route of light from the backlight source to the film piece set is prolonged so that the light can be subjected to coupling and reflection fully in the reflection cavity, and the wasteof the light source is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] In the liquid crystal display device, the liquid crystal display panel is a passive luminous element, which does not emit light itself, but is illuminated by the backlight module below it. The backlight module is a flat uniform lighting device, such as figure 1 As shown, it is generally equipped with a backlight source, a light guide plate, a reflector, a diaphragm module, a backplane and a middle frame. The backlight is generally EL (ElectroLuminescent, electroluminescent), CCFL (Cold Cathode Fluorescent Lamp, cold cathode fluorescent lamp) and LED (LightEmitting Diode, light-emitting diode). One has become the main backlight material on the market. CCFL is a line light source, and LED is a point light source. It is necessary to use a light guide plate to convert the line light source and point light sour...
