Abstract
The present invention can solve the problem that an existing organic light-emitting diode pixel circuit has a single function or a complicated structure. An organic light-emitting diode pixel circuit of the present invention includes: a touch fingerprint detection module configured to detect whether a touch occurs or not and whether the touch is caused by a convex portion of a fingerprint or a concave portion of the fingerprint, and send a result of the detection to a read line, under the control of a first scanning signal and a second scanning signal; and a compensation display module including an organic light-emitting diode and at least one driving transistor, and configured to eliminate a shift of a threshold voltage of the driving transistor and drive the organic light-emitting diode to display under the control of at least the first scanning signal, the second scanning signal, and a data signal.
