  • Patent number: 10809857
    Abstract: A display device includes a housing, an operation plate, an electrostatic sensor, a piezoelectric sensor, a controller, a storage unit, a display, and a communication unit. When an output voltage of the piezoelectric sensor indicates a first voltage value (Vth1) or larger, the controller determines that the piezoelectric sensor has detected a change in a first pressing force and performs first processing. When an output voltage of the piezoelectric sensor indicates a second voltage value (Vth2) or larger, the controller determines that the piezoelectric sensor has detected a change in a second pressing force. When the piezoelectric sensor detects the change in the second pressing force and the electrostatic sensor continuously detects a touch during a period from the detection of the first pressing force to the detection of the second pressing force, the controller executes second processing.

  • Patent number: 10795489
    Abstract: A detecting method for a touch panel is disclosed. The sensing electrode of the detecting method is indirectly and repeatedly charged several times via the charge holding capacitor circuit to reach a certain higher voltage. The driving electrode is switched to the first voltage or the second voltage under the cooperation of the driving circuit when several measuring cycle is conducted. After the voltage is switched every time, several measured values of different situations are obtained rapidly so as to eliminate the noise to get the best signal via several measured values. There is only to wait the balancing time in the measuring cycle, which effectively shortens the reaction time of the touch detecting.
