Abstract
A color display device that increases the efficiency of use of white light emitted from an organic light-emitting diode (OLED) in producing an improved color display. The device includes a plurality of color OLED display pixels, which include an OLED, a color filter layer, and a color conversion matrix sandwiched between the OLED and the color filter layer. The color filter layer has a plurality of color filter elements including a red, green and blue color filter element. The array of subpixels comprised in the color conversion matrix is composed of semiconductor nanocrystals uniformly dispersed in an organic binding material, which may be employed in either down-emitting or up-emitting color OLED display devices.
