Abstract
A touch detection device includes a control circuit. The control circuit is configured to: detect whether at least one zone of a touch panel is touched according to a plurality of touch sensing values corresponding to a plurality of touch sensing electrodes of the touch panel; and, to each of the at least one touched zone, determine the touched zone is caused by a finger touch or a liquid touch according a solar energy conversion efficiency value, wherein the solar energy conversion efficiency value represents how much solar energy is converted to electricity.
