Abstract: The present disclosure relates to a display device and sensing method. A display device includes a plurality of pixels. At least one of the pixels includes an organic light emtting diode (OLED) and a driving transistor. The driving transistor is connected in series with the OLED with a node between the OLED and the driving transistor. During a programming period the driving transistor is turned off and the OLED is turned on. During a discharging period the driving transistor is turned off and a voltage charged on the node during the programming period is discharged through the OLED. During a sensing period the OLED is turned off and the driving transistor is turned on to generate a pixel current to be sensed.
