Abstract:
A touch panel and a touch screen display device are provided. The touch panel includes: a base plate including a display area and a border area; and a capacitive touch structure and an electromagnetic touch structure that are provided on a same side of the base plate; where the electromagnetic touch structure includes multiple first coils each extending in a first direction and multiple second coils each extending in a second direction; every two adjacent coils of the multiple first coils partly overlap each other; every two adjacent coils of the multiple second coils partly overlap each other; and the first direction is perpendicular to the second direction. The touch panel includes a capacitive touch structure for capacitive touch detection and an electromagnetic touch structure for electromagnetic touch detection, and thus may achieve both capacitive touch detection and electromagnetic touch detection.
