Abstract:
1. A touch screen, comprising: a sensor array layer, which comprises M×N capacitive sensors, wherein M rows of the capacitive sensors are disposed along a first axis, and N columns of the capacitive sensors are disposed along a second axis; a microprocessor, which comprises a plurality of pins correspondingly coupled to the capacitive sensors, wherein when the touch screen is touched to change at least one of sensing values of the capacitive sensors in the sensor array layer, the microprocessor performs an interpolation calculation to determine a touched coordinate according to the sensing values sensed by the capacitive sensors; and M×N sensing lines respectively electrically connected to the M×N capacitive sensors and the microprocessor, wherein the microprocessor assigns corresponding M×N threshold values to the M×N capacitive sensors according to a layout resistance of each of the sensing lines, and, judges whether the (I, J) wherein the greater the layout resistance is, the lesser the threshold values assigned.
