This is set considering the visual sensitivity of each color, and a white balance);
Therefore it would have been obvious to one having ordinary skill in the art to modify the invention disclosed by Jeon as modified by JUNG and ZENG to incorporate the teachings of HANAMURA to vary the thickness of the color filter for different color subpixels in order to adjust the light emission and maintaining white balance.
