SENSING DEVICE AND METHOD OF SENSING A LIGHT BY USING THE SAME

摘要

In a sensing device and a method for sending a light by using the same, the sensing device includes: a lower panel; an upper panel facing the lower panel; a liquid crystal layer disposed between the lower panel and the upper panel; an infrared ray sensor formed in at least one of the lower panel and the upper panel; and a visible ray sensor formed in at least one of the lower panel and the upper panel. The sensing device simultaneously includes the infrared ray sensor and the visible ray sensor such that a touch sensing function or an image sensing function having high reliability may be realized.

1. A sensing device comprising:
a lower panel; an upper panel facing the lower panel; and a liquid crystal layer disposed between the lower panel and the upper panel, the upper panel including an upper substrate having a first surface facing a direction where an object to be sensed would be positioned and an opposite surface facing the liquid crystal layer; a plurality of infrared ray sensors disposed in the upper panel on the opposite surface, each infrared ray sensor including a visible ray blocking film contacting the opposite surface, an insulating layer covering and contacting the visible ray blocking film, an active layer disposed on and contacting the insulating layer, a source and drain electrode, each contacting the active layer, the insulating layer and the opposite surface; and a plurality of visible ray sensors disposed in the upper panel on the opposite surface.
