Problems solved by technology

[0002] The display device provided by the prior art includes a fingerprint identification element. When the fingerprint identification element performs fingerprint identification, it reflects the light emitted from the display device through the finger to form reflected light, and the fingerprint identification element receives the reflected light and realizes fingerprint identification. , the intensity of reflected light will affect the accuracy of fingerprint recognition
Normally, the light emitted from the display device needs to pass through multiple film layers, so the intensity of the light emitted from the display device will be affected, thereby reducing the intensity of the reflected light

Abstract

The invention discloses a display device, comprising: a display panel and a backlight module arranged oppositely, the display panel includes a fingerprint identification area, and the fingerprint identification area includes a plurality of fingerprint identification elements; the backlight module includes a first light source and a plurality of second Lamp beads; the light emitted by the first light source is emitted through the backlight module to provide a light source for the display panel; a plurality of second lamp beads are arranged at the position corresponding to the fingerprint identification area of ​​the backlight module, and the second lamp beads have a second light output angle. The second light emitting angle is not greater than 15°. By controlling the angle of the second light emitting angle, crosstalk of light between adjacent second lamp beads can be avoided, and the accuracy of fingerprint identification can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background technique [0002] The display device provided by the prior art includes a fingerprint identification element. When the fingerprint identification element performs fingerprint identification, it reflects the light emitted from the display device through the finger to form reflected light, and the fingerprint identification element receives the reflected light and realizes fingerprint identification. , the intensity of reflected light will affect the accuracy of fingerprint identification. Normally, the light emitted from the display device needs to pass through multiple film layers, so the intensity of the light emitted from the display device will be affected, thereby reducing the intensity of reflected light. Contents of the invention [0003] In view of this, the present invention provides a display device, comprising: a displa...
