Abstract

The invention discloses a backlight module and a display device, which relates to the field of display technology. The backlight module includes: a light guide plate and a side-type light source; theguide plate includes a hollowed-out part, a first side and the second side which are relative, the hollowed-out part penetrates through the light guide plate along the light guide plate thickness direction; the first side is the light inlet side of the light guide plate, the area between the hollowed-out part and the second side is a first area; the light guide plate comprises a plurality of firstlight guide grooves, the first light guide groove extends from the outer edge of the light guide plate towards the hollowed-out part, and the first guide light guide groove passes through the first area. Compared with the existing technology, the brightness of the first area can be increased and the uniformity of the brightness of the light guide plate is enhanced, so as to improve the quality ofthe backlight module.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a backlight module and a display device. Background technique [0002] Display devices have gradually become an indispensable part of people's daily life. Improving the display quality of display devices has become one of the important research directions. [0003] The prior art provides a display device including a display panel and a backlight module. Please refer to figure 1 , figure 1 It is a structural schematic diagram of a backlight module provided by the prior art. The backlight module includes a light guide plate 01 and an LED light bar 02 , and the LED light bar 02 is arranged opposite to the side 03 of the light guide plate 01 . The light guide plate 01 includes a hollow part 04, and the hollow part 04 can be used for installing electronic components such as a camera. Due to the existence of the hollow part 04, the light provided by the LED ligh...
