Abstract

Embodiments of the present invention disclose a display device, a manufacturing method thereof, and an electronic device. The display device includes: a display panel, the display panel includes a first side surface for displaying an image and a second side surface disposed opposite to the first side surface side surface; a light-transmitting film layer, located on the second side surface of the display panel, the light-transmitting film layer is divided into a light-absorbing area and a plurality of light-transmitting areas defined by the light-absorbing area; a plurality of fingerprint identification units, located on the light-transmitting film On the side of the layer away from the display panel, a plurality of fingerprint identification units and a plurality of light-transmitting areas are respectively arranged correspondingly, each fingerprint identification unit includes a photosensitive device, and the light-transmitting area of ​​the light-transmitting film layer is perpendicular to the direction of the display panel. The projection covers the photosensitive device corresponding to the fingerprint identification unit. In the embodiment of the present invention, the light-transmitting area of ​​the light-transmitting film layer accurately aligns the photosensitive device of the fingerprint identification unit, reduces the loss of light transmittance, avoids the generation of moiré, realizes the light collimation effect, and improves the accuracy of fingerprint identification.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display device, a manufacturing method thereof, and electronic equipment. Background technique [0002] Fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with the fingerprint recognition function, the user only needs to touch the fingerprint recognition sensor of the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display device with fingerprint identification function, when the light emitted by the fingerprint identification light source is reflected by the finger, it will be irradiated on a plurality of fingerprint iden...
