Abstract
The present application discloses a touch-control pixel-driving circuit. The circuit includes a driving transistor coupled to a data line and a read line; an organic light-emitting diode (OLED) coupled to the driving transistor. The circuit also includes a light-sensing-touch sub-circuit coupled to the data line and the read line and configured to be reset by a first and a second control signals to send a raw signal flour the data line to the read line, and to generate a sensing signal depended on a change of the raw signal due to a touch and send the sensing signal to the read line. Further, the circuit includes a driving sub-circuit coupled to the driving transistor and configured to charge and discharge the driving transistor using a power-supply voltage and a data signal controlled by the first, the second, and a third control signals, and to drive the OLED for emitting light.
