Apparatus to sense touching and proximate objects
摘要:
A sensing apparatus may emit light, radiated from a light source, to an upper part and may preserve light in an internal part, based on a total internal emission angle of the light. Also, the sensing apparatus may project the light radiated to the upper part, and the light preserved in the internal part, towards at least one of a touching object and the proximate object.
