Abstract

Disclosed is a touch display module, the touch display module having a display area, and a non-display area that is connected to the display area. The touch display module comprises a first lead and a second lead, the second lead being disposed at a side of the first lead distant from the display area, a second signal is loaded on the second lead, the second signal having the same frequency as, but the opposite direction to, a first signal loaded on the first lead; the second signal can generate electromagnetic interference radiation opposite to that of the first signal, to weaken electromagnetic interference radiation generated by the first signal, thereby reducing the electromagnetic interference radiation of the touch display module and reducing interference with electronic devices. Also disclosed are a touch display apparatus and an electronic device.
