An organic light-emitting diode (OLED) pixel circuit, a method for driving the OLED pixel circuit and a display apparatus solve the problems in the prior art that a control circuit and the manufacturing process of a built-in touch screen are complex. The OLED pixel circuit comprises a data writing unit, a storage unit, a drive unit, an OLED, a first control unit, a second control unit, and a touch detection unit. The first control unit is used for importing power source signals into the data writing unit and connecting the OLED and the drive unit; the data writing unit is used for importing power source voltage signals and data line voltage signals, and meanwhile 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 control output signals, and outputting the touch control output signals to a drive integrated circuit through the touch detection unit, and meanwhile, the drive unit is further used for providing drive currents for the OLED; and the second control unit is used for connecting the drive unit and a grounding level. |
