TOUCH SENSING APPARATUS

摘要

PURPOSE: A touch sensing apparatus is provided to decrease the number of light sources by guiding the light from a light source to optical sensors through optical guide patterns. CONSTITUTION: An incident plate faces a light source(10) and receives the light from the light source. An emission plane faces a light distribution unit(30) and emits the light of the light source. Light guide patterns(51) protrude from a plane facing the emission plane. The light guide patterns guide the light of the light source to the light distribution unit through the emission plane.
