Abstract
A micro light emitting diode touch display panel is provided with a pixel driving circuit, a power supply voltage signal line electrically connecting the pixel driving circuit, a first contact electrode electrically connecting the power supply voltage signal line, and a micro light emitting unit bonded to connect the first contact electrode. In a touch driving phase, the first contact electrode is re-used as a touch electrode, and the power supply voltage signal line is re-used as a touch signal line, thereby reducing the production costs, and promoting the production capacity as well as ensuring the touch control and display effects.
