Abstract

An electromagnetism and capacitance integrated touch screen, a touch display panel and a touch display apparatus are provided. Multiple virtual electrodes (generally located between a drive electrode and a detection electrode) in a capacitance touch structure are arranged to be coil-shaped, and the coil-shaped virtual electrode functions as a coil of an electromagnetism touch structure. In this way, the electromagnetism touch structure can be implemented without adding extra structure and process to the capacitance touch structure, thereby achieving compatibility between the electromagnetism touch structure and the capacitance touch structure.
