ABSTRACT:
A new type touch sensing device comprises a touch panel with a plurality of transparent touch electrodes, a LC parallel resonant circuit connected to the touch electrode and an oscillation circuit. The LC resonant circuit has a resonant point on a same frequency with the oscillation frequency of the oscillation circuit. The touch
on-touch condition to the touch electrode is detected as a change of voltage value at the connecting point of the LC resonant circuit and touch electrode with an increased ON-OFF ratio.
