Abstract

The invention discloses a backlight module and a display device. The backlight module includes: a light guide plate, including at least two light guide plate units spliced ​​with each other in the first direction, the surface of the light guide plate unit that is in contact with the adjacent light guide plate is a contact surface, and the contact surface is polished, and the light guide plate unit The light incident side has a boss, and the boss is arranged at least on the side close to the contact surface; the light bar includes a flexible circuit board and at least two light source groups, the flexible circuit board includes a light source driving circuit, and the light source driving circuit can realize the control of each light source. Individual driving of the groups, one light source group corresponds to one light guide plate unit, the light source group includes a plurality of light sources arranged along the first direction, and one boss faces one light source. The invention can realize partitioned display of the backlight source, is beneficial to reduce the power consumption of the backlight module, can effectively reduce the mutual interference of light between the left and right light guide plate units, and improve the display effect of the partitioned display.

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] In the existing display device technology, the display panel is mainly divided into two mainstream technologies of a liquid crystal display panel and an organic self-luminous display panel. Among them, the liquid crystal display panel forms an electric field capable of controlling the deflection of liquid crystal molecules by applying a voltage on the pixel electrode and the common electrode, and then controls the transmission of light to realize the display function of the display panel; the organic self-luminous display panel uses organic electroluminescent materials, When current passes through the organic electroluminescent material, the luminescent material will emit light, thereby realizing the display function of the display module. [0003] The LCD panel needs a backlight module to p...
