Abstract
The present disclosure provides an optical fingerprint/palmprint identification device, and a touch display panel and a display apparatus which includes the optical fingerprint/palmprint identification device, which enables easy determination of relative positions of ridges and valleys of a fingerprint/palmprint. The optical fingerprint/palmprint identification device includes: a photosensitive sensor configured for acquiring an optical signal indicative of fingerprint/palmprint information, and converting the acquired optical signal into a current; a storage capacitor configured as a separate capacitor in the optical fingerprint/palmprint identification device and electrically connected to the photosensitive sensor so as to receive and store the current from the photosensitive sensor during scanning a fingerprint/palmprint; and a switch transistor electrically connected to the storage capacitor so as to output the current stored in the storage capacitor during reading out a current.
