Abstract
In a touch module, a light emitted by the light source undergoes a total reflection in the third substrate. when a first spacer is pressed against a third substrate by pressing a location on a second substrate, the light undergoing the total reflection in the third substrate escapes out of the third substrate and irradiates onto a photosensitive part corresponding to the pressed first spacer, the irradiated photosensitive part generates an electrical signal, and a pressed location on the second substrate is determined by detecting the electrical signal transmitted to an optical current detection line electrically connected to the irradiated photosensitive part. The touch module may reduce the cost and is adapted to be applied to a large size touch screen.
