A touch-control pixel-driving circuit and method thereof, a touch-control display apparatus

A touch-control pixel-driving circuit in a display apparatus, the circuit comprising:

• a driving transistor coupled to a data line and a read line;
• an organic light-emitting diode (OLED) having a first electrode coupled to the driving transistor and the read line, and a second electrode coupled to a reference voltage terminal;
• a light-sensing-touch sub-circuit coupled to the data line and the read line and configured to be reset by a first control signal and a second control signal to send a raw signal to the read line based on a high-level voltage at the data 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;
• and
• a driving sub-circuit coupled to the driving transistor and configured to charge and discharge the driving transistor using a power-supply voltage from a power terminal and a data signal from the data line controlled by the first control signal, the second control signal and a third control signal, and to drive the OLED for emitting light.
