Touch-control display device with integration of capacitive and electromagnetic touch units

摘要

A touch-control display device is disclosed. The display device includes first, second, and third touch-control structures, a first plate, and a second plate opposing the first plate. The first and second touch-control structures form a capacitive touch-control structure, the third touch-control structure is an electromagnetic touch-control structure, and the first, second and third touch-control structures are respectively disposed on an inner side of the first plate, on an external side of the first plate, and on an inner or external side of the second plate. In addition, the first, second, and third touch-control structures are separated by one or more insulating layers.
