摘要（英）：

The invention provides a touch and display drive circuit, a drive method and a display device. The touch and display drive circuit comprises a data writing control unit, a storage unit, a touch sensing unit, a drive compensation control unit, a drive unit, a light-emitting control unit and a light-emitting unit, wherein the data writing control unit is used for controlling voltage signals of a data line to be written in the storage unit, the storage unit is used for providing voltages for the drive unit, the light-emitting control unit is used for controlling the light-emitting unit to emit light, the drive unit is used for providing touch detection currents or drive currents of the light-emitting unit, the drive compensation control unit is used for compensating voltage values of the storage unit, and the touch sensing unit is used for changing the voltage values of the storage unit and providing output for the touch detection currents when the touch occurs. According to the technical scheme, the touch detection and pixel display can be integrated, and the thickness of a display screen can be reduced.
