Abstract

The invention provides a backlight module and a display device. The display device comprises a backlight module and a display panel. The backlight module comprises a light guide plate and light sources. The light guide plate is provided with a bottom surface where a middle groove is formed. The middle groove is provided with a dimming inclined plane. The light sources are arranged on both sides of the light guide plate and correspond to the dimming inclined plane. The invention can be used to adjust the light intensity distribution and improve the central brightness of the picture of the display device.

Description

【Technical field】 [0001] The invention relates to a backlight module and a display device, in particular to a backlight module and a display device which can adjust light intensity distribution and improve the central brightness of a picture. 【Background technique】 [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal display panel and a backlight module. The backlight module can be divided into side-light type and direct-light type according to the incident position of the light source, so as to provide backlight to the liquid crystal display panel. [0003] Generally, for LCDs, the central brightness is an important parameter. Generally, the enhancement of the central brightness of the liquid crystal display can be realized by increasing the brightness of the backlight source (eg light emitting diode) of the backlight module. However, this method tends to i...
