Abstract
A mutual-capacitance touch apparatus and highly sensitive mutual-capacitance touch sensing method thereof, the method includes: providing a touch apparatus including: a plurality of first touch electrodes and a plurality of second touch electrodes, a touch controller including a touch driving signal generator, a touch receiver, and an amplifier with gain larger than zero. The touch controller sequentially or randomly applies a touch driving signal to a selected first touch electrode, and senses a touch sensing signal at a second touch electrode by the touch receiver, and processes the touch sensing signal by the amplifier with gain larger than zero, then outputs the processed touch sensing signal to at least a conductor close to the second touch electrode.
