<p>An organic light emitting diode (OLED) pixel circuit and a driving method thereof, and a display apparatus relate to the technical field of display, and can solve the problems that an existing control circuit and the manufacturing process of a built-in touch screen are complex, so that a touch display apparatus is thinner and lighter. The OLED pixel circuit comprises: a data writing unit, a storage unit, a drive unit, an OLED, a light emitting control unit, and a touch detection unit. The data writing unit is used for writing power voltage signals in the storage unit and writing data line voltage signals in the storage unit. The storage unit is used for providing voltages for the drive unit. The touch detection unit is used for sensing touch and generating detection signals. The drive unit is used for converting the detection signals into touch output signals, the touch output signals are output through the touch detection unit, and meanwhile the drive unit is further used for providing drive currents for the OLED. The light emitting control unit is used for enabling the drive unit and the OLED to be connected.</p> |
