Problems solved by technology

[0005] However, in the known technology, such as figure 1 As shown, since the light guide plate 122 is generally made of a light-transmitting material, the light that enters the light guide plate 122 from the light incident surface 1 will directly enter the inside of the light guide plate 122, so that the area adjacent to the light guide plate 122 and the LED light source 121 (such as figure 1 In the region A), light leakage often occurs, causing hot spots on the display panel 11, resulting in poor display quality and a decline in product competitiveness.

Abstract

The invention provides a backlight module and a display device; the backlight module comprises a light guide plate and a light-emitting unit; the light guide plate has at least one incident side and an emergent side connected with the incident side; the light-emitting unit has a substrate, at least one light-emitting device and a light exiting side, the light-emitting devices are disposed on the substrate, and light source is provided for the light-emitting devices by the light exiting side and enters the light guide plate from the incident side out of the light exiting side, wherein the incident side has a first inclination angle to a direction perpendicular to the light exiting side, the light exiting side has a second inclination angle to the direction, and the first inclination angle and the second inclination angle are identical in nature.

Description

technical field [0001] The invention relates to a backlight module and a display device. Background technique [0002] Since the display medium of the liquid crystal display panel does not emit light, in order to achieve the display effect, it is necessary to provide a surface light source (that is, a backlight module) with sufficient brightness and uniform distribution to the liquid crystal display panel to display the desired image. In addition, due to continuous improvements in technology and materials of light emitting diodes (Light Emitting Diodes, LEDs), the luminous efficiency of light emitting diodes has been greatly improved. Due to the characteristics of low power consumption, long service life, high safety, short light-emitting response time and small size, light-emitting diodes are gradually applied in backlight modules of display devices. [0003] Please refer to figure 1 As shown, it is a schematic diagram of a known display device 1 . [0004] The display d...
