发明名称 MUTUAL INDUCTANCE TYPE CAPACITIVE TOUCH SCREEN
摘要 The present invention provides a mutual capacitive touch panel, including: a plurality of driving lines; a plurality of sensing lines intersecting with the plurality of driving lines; a signal output unit disposed at input ends of the driving lines is configured to output driving signals with different frequencies to all the driving lines; a preamplifier disposed at output ends of the sensing lines is configured to capture sensing signals from the sensing lines, and amplify and then output the sensing signals to a signal separation unit; the signal separation unit connected to the preamplifier is configured to separate the sensing signals with different frequencies and obtain addresses of the driving lines corresponding to the sensing signals. In the present invention, driving signals with different frequencies are outputted by the signal output unit to all the driving lines, respectively.
