Abstract

The invention, which relates to the technical field of display, discloses a backlight module and a display device. The backlight module comprises a fingerprint identification area, a non-fingerprint identification area, and a light guide plate. A plurality of grooves are formed in the surface of one side of the light guide plate and are arranged in a light emitting surface of the light guide plate; the grooves include a plurality of first grooves formed in the non-fingerprint identification area and a plurality of second grooves formed in the fingerprint identification area; and the first grooves are linear grooves and the second grooves are curved grooves. Therefore, a problem that the luminance of the fingerprint identification area in the display device is lower than that of the non-fingerprint identification area in the prior art is solved; and the luminance uniformity of the display device is improved.

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 characteristics 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 in 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 identification technology is usually combined with display technology, so that the display panel not only has a display function, but also can perform fingerprint identification, thereby enriching the functions of the display panel and improving the security performance of information in the display device. Furthermore, the combination of optical fingerprin...
