Abstract
A touch device is provided. The touch device includes a touch panel, a first control circuit, and a second control circuit. The touch panel is divided into a first touch area and a second touch area. The first control circuit is coupled to the first touch area and performs a first touch-detection operation on the first touch area. The second control circuit is coupled to the second touch area and performs a second touch-detection operation on the second touch area.
Claims17
A touch device comprising
- a touch panel divided into a first touch area and a second touch area;
- a first control circuit coupled to the first touch area and performing a first touch-detection operation on the first touch area;
- a second control circuit coupled to the second touch area and performing a second touch-detection operation on the second touch area;
- a processing circuit calculating a first number of times that the first touch area is touched and a second number of times that the second touch area is touched during a predetermined time and determining whether the first number of times exceeds a threshold value and whether the second number of times exceeds the threshold value to determine which one among the first and second touch areas is the most frequently touched area, and
- wherein when the processing circuit determines that the first touch area is the most frequently touched area, the processing circuit controls the first control circuit to perform the first touch-detection operation in a normal mode and controls the second control circuit to perform the second touch-detection operation in a power-saving mode.

A control method for a touch device, comprising
- dividing a touch panel of the touch device into a first touch area and a second touch area;
- performing a first touch-detection operation on the first touch area through a first control circuit;
- performing a second touch-detection operation on the second touch area through a second control circuit;
- calculating a first number of times that the first touch area is touched and a second number of times that the second touch area is touched during a predetermined time, and
- determining whether the first number of times exceeds a threshold value and whether the second number of times exceeds the threshold value to determine which one among the first and second touch areas is the most frequently touched area;
- when it is determined that the first touch area is the most frequently touched area, switching the first control circuit to a normal mode to perform the first touch-detection operation, and further switching the second control circuit to a power-saving mode to perform the second touch-detection operation.
