Abstract
A coordinate positioning system of touch panel is disclosed, which comprises a analog resistive touch panel, a signal amplifier module, an adder module, a subtractor module, and a divider module. The signal amplifier module receives and processes the current signal which is generated by the user's clicking the specific position of the touch panel and comprises the specific position message, so as to generate the output of a first set of amplifying signal and a second set of amplifying signal. The adder module proceeds the adding computation onto the first set of amplifying signal and a second set of amplifying signal, so as to generate the first adding signal and the second adding signal for outputting. The subtracter module proceeds the subtracting computation onto the first set of amplifying signal and a second set of amplifying signal, so as to generate the first subtracting signal and the second subtracting signal for outputting. The divider module proceeds the dividing computation onto the first adding signal and a first subtracting signal to generate the first coordinate signal, and proceeds the dividing computation onto the second adding signal and a second subtracting signal to generate the second coordinate signal, so that the coordinate of the specific position on the panel can be assured according to the first and the second coordinate signals.
