[0073] In the first case, please also refer to Figure 5 . Assume: the elasticity parameter is 0.5, the capacitance signal of the touch point P1 is 140, the capacitance signal of the touch point P2 is 20, the capacitance signal of the touch point P3 is 30, and the capacitance signal of the touch point P4 is 150.
[0074] The maximum capacitance signal obtained from step S206 is 150; the minimum capacitance signal is 20.
[0075] From step S208, the maximum capacitance signal, the minimum capacitance signal and the elasticity parameter are substituted into the formula: threshold value = maximum capacitance signal × elasticity parameter + minimum capacitance signal × (1 - elasticity parameter);
[0076] Threshold value = 150× 0.5 + 20× (1 – 0.5);
[0077] Threshold = 85.
[0078] From step S210, compare the capacitance signals of the touch points P1, P2, P3 and P4 with the threshold value: the touch points P1 and P4 are greater than the threshold value to be a real touch poin...
