1. An organic light emitting dioxide (OLED) pixel circuit, comprising a data writing unit, a driving unit, an OLED, a first control unit, a second control unit and a touch detecting unit, wherein,
the first control unit, in a touch detecting stage and an OLED light-emitting stage, is used for importing a power supply voltage signal into the data writing unit under the control of a scanning line, and, in the OLED light-emitting stage, is used for turning on the OLED and the driving unit; the data writing unit, in the touch detecting stage and the OLED light-emitting stage, is used for importing the power supply voltage signal under the control of a first light-emitting control line, and importing a data line signal under the control of the scanning line and a second light-emitting control line, and meanwhile is used for supplying voltage to the driving unit; the touch detecting unit, in the touch detecting stage, is used for sensing touch under the control of a touch signal level control line, and generating a detecting signal; the driving unit, in the touch detecting stage, is used for converting the detecting signal into a touch output signal, which is output to a driving integrated circuit (IC) via the touch detecting unit, under the control of the touch signal level control line, and in the OLED light-emitting stage, is used for providing driving current for the OLED; and the second control unit, in the OLED light-emitting stage, is used for connecting the driving unit to a ground level under the control of a third light-emitting control line. |
