Patent ID: 8896732

Claim:
A pixel comprising: a first color filter layer comprising a first pixel color filter layer for a first color in a first color region, a second pixel color filter layer for a second color in a second color region, and a third pixel color filter layer for a third color in a third color region, wherein the first color filter layer is configured to transmit a signal including a visible light and an IR; and a second color filter layer disposed at one side of the first color filter layer, and comprising the first pixel color filter layer, the second pixel color filter layer on the first pixel color filter layer, and the third pixel color filter layer on the second pixel color filter layer in an IR region, wherein the second color filter layer is configured to transmit a signal including an IR, in which a visible light is blocked, wherein the first color region, the second color region, the third color region, and the IR region are disposed on the same plane; wherein the pixel is formed by: forming the first pixel color filter layer in the first color region, the second color region, the third color region, and the IR region; removing the first pixel color filter layer from the second color region and the third color region; forming the second pixel color filter layer in the first color region, the second color region, the third color region, and the IR region; removing the second pixel color filter layer from the first color region and the third color region; forming the third pixel color filter layer in the first color region, the second color region, the third color region, and the IR region; and removing the third pixel color filter layer from the first color region and the second color region; and wherein the visible light transmitted by the first color filter layer is independently distinguishable from the IR transmitted by the first color filter layer due to a difference between the signal transmitted by the first color filter layer and the signal transmitted by the second color filter layer.
