Problems solved by technology

[0003] However, in the liquid crystal display (LCD) fingerprint technology in the prior art, the fingerprint recognition under the screen can be divided into a side type and a direct type. The side type fingerprint recognition usually sets the infrared fingerprint recognition light source under the cover, which will cause The widening of the border is inconsistent with the current development trend of thinner, lighter and full-screen electronic devices

Abstract

The invention discloses a backlight module and a display device. The backlight module comprises a backlight light bar, a shading layer which comprises a hollowed-out part and is located on the side, close to the light emitting surface of the backlight module, of the backlight light bar, and multiple first light emitting units which are located on the side, close to the light emitting surface of the backlight module, of the backlight bar and electrically connected with the backlight light bar, and in the direction perpendicular to the backlight module, the orthographic projections of the firstlight emitting units on the light emitting surface of the backlight module and the orthographic projection of the hollowed-out part on the light emitting surface of the backlight module are at least partially overlapped. According to the backlight module, the first light emitting units are integrated in the backlight module, so that the internal structural space of an electronic product is saved,and the product meets the ultrathin design requirement.

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] With the rapid development of liquid crystal display (LCD) and the popularity of full screens, fingerprint recognition technology under the screen is the future development trend. Compared with the recognition that occupies part of the display area on the screen, the advantage of fingerprint recognition under the screen is that it can ensure the integrity of the display screen, and the finger can be recognized directly on the display screen. [0003] However, in the liquid crystal display (LCD) fingerprint technology in the prior art, the fingerprint recognition under the screen can be divided into a side type and a direct type. The side type fingerprint recognition usually sets the infrared fingerprint recognition light source under the cover, which will cause The widening of the border is ...
