摘要:
The present application discloses a touch sensing apparatus for detecting a touch motion by induction. The touch sensing apparatus includes a base substrate; a black matrix layer on the base substrate defining a plurality of light transmissive regions; an inductor layer on the base substrate, the inductor layer including at least one inductor unit, each of the at least one inductor unit having a multi-turn planar coil structure, a projection of the inductor layer on the base substrate substantially overlapping with that of a portion of the black matrix layer; and at least one first sensing circuit coupled to the at least one inductor unit and configured to be provided with an AC signal and to detect a change of the AC signal induced by the touch motion.
