Display panel and display apparatus

Abstract

The invention provides a display panel and a display apparatus. The display panel comprises a light-emitting unit array substrate, a packaging substrate and at least one fingerprint identification unit, wherein each fingerprint identification unit comprises a common electrode, a second electrode, a PIN junction and a first electrode; the second electrode, the first electrode and the PIN junction form a photosensitive diode; the common electrode is electrically connected with the first electrode; the second electrode and the common electrode form a storage capacitor; the common electrode and / or the first electrode comprises a first body part and a first protruding part; the second electrode comprises a second body part and a second protruding part; and vertical projections, on a substrate, of the first protruding part and the second protruding part are overlapped and are both located between vertical projections, on the substrate, of two adjacent light-emitting units in a second direction. According to the display panel and the display apparatus provided by the invention, the fingerprint detection stability is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] Since fingerprints are inherent to each person, they 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 unit of the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] Fingerprints are composed of a series of ridges and valleys located on the surface of the fingertip skin. Since the intensity of light reflected by the ridges and valleys received by the fingerprint recognition unit is different, the reflected light formed at...

AI Technical Summary

Problems solved by technology

The fingerprint identification unit usually includes a photodiode and a storage capacitor, which together convert the reflected light through the touch body into a current / voltage signal, but due to the small capacitance value of the storage capacitor in the prior art, the fingerprint identification unit exists The risk of false fingerprint detection affects the normal use of the display panel
