Problems solved by technology

However, in the known technology, such as figure 1 As shown, when light is incident on the light guide plate 122, the area adjacent to the light guide plate 122 and the LED light source 121 ( figure 1 Area A), light leakage often occurs, causing the display panel 11 to produce a hot spot phenomenon (commonly known as a bright spot), resulting in poor display quality and a decline in the competitiveness of the product

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a light guide plate, a carrier, and a light emitting unit, wherein the light guide plate comprises at least one light entering surface and a light exiting surface connected with the light entering surface; the carrier is adjacent to the light guide plate, and comprises a setting surface; the light emitting unit is arranged on the setting surface; light emitted by the light emitting unit enters the light guide plate via the light entering surface, and exits from the light guide plate via the light exiting surface; a first inclined angle is formed between the light entering surface and a direction perpendicular to the light exiting surface; a second inclined angle is formed between the setting surface and the direction perpendicular to the light exiting surface; and the first inclined angle and the second inclined angle are substantially the same as each other.

Description

technical field [0001] The invention relates to a backlight module and a display device. Background technique [0002] Since the liquid crystal itself 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 (ie, a backlight module) with sufficient luminance and uniform distribution to the liquid crystal display panel to display desired images. 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. Different from ordinary fluorescent lamps or energy-saving light bulbs, light-emitting diodes have the characteristics of low power consumption, long service life, high safety, short luminous response time and small size, so they are gradually applied in backlight modules of display devices. [0003] Please refer to figure 1 As shown, it is a s...
