发明名称 TOUCH SENSING METHOD AND TOUCH SENSING APPARATUS OF CHARGE DISTRIBUTION TYPE
摘要 A touch sensing method of charge distribution type is disclosed. Firstly, charges in a panel are removed. Next, a scanning signal is provided to scan a plurality of sensing regions of the panel. Subsequently, the panel is set in a first switching mode for charging the panel with the scanning signal. Thereafter, the panel is set in a second switching mode for modifying a distribution of charges injected into the panel. Next, an equivalent voltage is acquired after the charges are distributed at an equilibrium state. Furthermore, a touch sensing apparatus with charge distribution type is provided herein.
