The disclosure relates to a method for recognizing touch. A first value T1 and a second value T2 are set. A number of first sensing values C1 are obtained. C1 is compared with T1 and T2. When C1 is greater than or equal to T1, a touch with finger is recognized. When C1 is smaller than T2, no touch is recognized. When C1 are greater than or equal to T2 and smaller than T1, following steps are taken. A third value T3 is set. At least three driving electrodes are driven and a number of second sensing values C2 are obtained. A number of maximum sensing values C2peak are selected from the C2 and compared with T3. When C2peak are greater than or equal to T3, a touch with glove is recognized. And when not, no touch is recognized. |

1. A method of recognizing touch on a touch panel, wherein the touch panel comprises a plurality of sensing electrodes and a plurality of driving electrodes, and the method comprising:
setting a first value T1 and a second value T2, wherein the second value T2 is smaller than the first value T1; driving the plurality of driving electrodes one by one, sensing touch signals and obtaining a plurality of first signal values C1; comparing the plurality of first signal values C1 with the first value T1 and the second value T2, when the plurality of first signal values C1 is greater than or equal to the first value T1, recognizes as a touch with finger; when the plurality of first signal values C1 is smaller than the second value T2, recognizes as no touch; and when the plurality of first signal values C1 is greater than or equal to the second value T2 and smaller than the first value T1, takes the following steps; setting a third value T3; driving the plurality of driving electrodes several times and sensing a plurality of second signal values C2, wherein an n is defined as the sequence of driving, at least adjacent three of the plurality of driving electrodes of labeling n, n+1, and n+2, are driven simultaneously each time; and selecting a maximum signal value C2peak from the plurality of second signal values C2, and comparing the maximum signal value C2peak with the third value T3, when the maximum signal value C2peak is greater than or equal to the third value T3, recognizes as a touch with glove; and when the maximum signal value C2peak is less than the third value T3, recognizes as no touch. |
