Pixel circuit for increasing accuracy of current sensing

Abstract

A pixel circuit for increasing accuracy of current sensing of an organic light-emitting diode (OLED) display is disclosed. In one aspect, the pixel circuit includes an OLED, a driving circuit, and first to third transistors. The driving circuit is configured to adjust a magnitude of a current flowing through the OLED based at least in part on a data signal received from a data line. The first transistor is configured to electrically connect the data line and a holding capacitor based at least in part on a scan signal. The second transistor is configured to electrically connect the holding capacitor and the driving circuit based at least in part on a write control signal. The third transistor is configured to electrically connect the data line and an anode electrode of the OLED based at least in part on a sensing control signal.
