Abstract: The disclosure provides a touch display device, a touch display panel, a touch display panel and a driving method. The touch display panel includes a first substrate, multiple micro light emitting devices, multiple micro driving devices and multiple touch driving electrodes. Each micro driving device corresponds to the multiple micro light emitting devices to drive the multiple micro light emitting devices to emit light. At least one touch driving electrode corresponds to at least one micro driving device. The touch driving electrode receives a signal transmitted to a corresponding micro driving device as a touch driving signal, or, the touch driving electrode receives a signal outputted by the corresponding micro driving device as the touch driving signal. Therefore, there is no need for a main driver chip to provide the touch driving signal to the touch driving electrode. Thus, the power consumption of the main driver chip is greatly reduced.
