DISPLAY PANEL, DISPLAY APPARATUS HAVING THE SAME, AND DRIVING METHOD THEREOF

摘要

A display panel having an array of a plurality of pixel units, each pixel unit including at least three subpixels (201,202) for image display, at least some of the plurality of pixel units including a semiconductor photodetector (102) for detecting biometric information;a plurality of first scan lines (Scan1) and a plurality of data lines (DL), each first scan line (Scan1) being connected to a row of subpixels (201,202), each data line (DL) being connected to a column of subpixels (201,202)； each subpixel (201,202) including a first transistor (T1) for image display; a plurality of common voltage terminals (V1), each common voltage terminal (V1) being connected to a semiconductor photodetector (102); a plurality of second scan lines (Scan2), each second scan line (Scan2) being connected to a plurality of semiconductor photodetectors (102) for providing a control voltage signal; each semiconductor photodetector (102) having a second transistor (T2); the second transistor (T2) being a phototransistor having a gate node connected to a corresponding second scan line (Scan2) for receiving the control voltage signal to turn on the second transistor (T2), and a first node connected to a corresponding common voltage terminal (V1); and a plurality of read lines (RL), each read line (RL) being connected to each semiconductor photodetector (102) in a column of pixel units.
