1results about How to "Realize the fingerprint recognition function" patented technology

This invention discloses a display device, including a display module, a flexible circuit board, a fingerprint recognition light source, and a fingerprint recognition element. A bonding area in the display module region is provided with bonding terminals. The flexible circuit board is electrically connected to the bonding terminals and is bent from the bonding area to a first surface of the display module. The first surface is opposite to the light-emitting surface of the display module. The flexible circuit board includes a first circuit board portion located on the side of the first surface away from the light-emitting surface. The fingerprint recognition light source is located on the side of the first circuit board portion closer to the display module, and the fingerprint recognition element is located on the side of the first circuit board portion away from the display module. Both the fingerprint recognition light source and the fingerprint recognition element are fixed to the first circuit board portion. The first circuit board portion is provided with a first opening, exposing the photosensitive surface of the fingerprint recognition element. The technical solution of this invention can improve the integration and fingerprint recognition accuracy of the display device.
