Abstract

The invention discloses a backlight module and a display device, and relates to the field of display technology. The backlight module includes: a fingerprint identification area and a non-fingerprint identification area; the backlight module further includes a light guide plate, and a surface on one side of the light guide plate is provided with a plurality of grooves, the grooves are located on the light-emitting surface of the light guide plate, the grooves include a plurality of first grooves located in the non-fingerprint identification area and a plurality of second grooves located in the fingerprint identification area, and the first grooves are linear grooves, The second groove is a curved groove. The invention solves the situation in the prior art that the luminous brightness of the fingerprint identification area in the display device is lower than that of the non-fingerprint identification area, and improves the brightness uniformity of the display device.

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] Fingerprints are inherently unique and invariable features of the human body that can be distinguished from others. With the rapid development of display technology, display panels with fingerprint recognition functions have gradually spread throughout people's lives, and fingerprint recognition is widely used in mobile phones. , personal digital assistants, computers and other electronic equipment display. [0003] At present, fingerprint recognition technology and display technology are usually combined, so that the display panel not only has a display function, but also can perform fingerprint recognition, thereby enriching the functions of the display panel and improving the security performance of information in the display device. Further, the combination of optical fingerprint recogni...
