An integrated organic light emitting diode (OLED) color display device is disclosed. The OLED display device comprises at least one pixel element (

10

) capable of emitting visible light of varying wavelengths. Pixel element (

10

) may comprise: a substrate (

100

), an addressable two-dimensional matrix of organic light emitting diodes (

120

) that emits monochrome light, a color conversion matrix element (

110

) capable of absorbing the monochrome light and re-emitting that light at different wavelengths, and cover element (

130

). Color conversion matrix element (

110

) may further comprise at least one red color converting subelement (

111

), at least one green color converting subelement (

112

), and at least one blue color converting subelement (

113

). The color converting subelements (

111, 112

, and

113

) may further comprise semiconductor nanocrystals (

140

) uniformly dispersed in a transparent organic binding material (

150

). The size distribution of the semiconductor nanocrystals (

140

) may be precisely controlled to define the capability for color conversion to a particular wavelength of re-emitted light. The color conversion matrix element (

110

) is fabricated separately from the organic light emitting diode matrix. A method for making an integrated organic light emitting diode display device comprising at least one pixel element (

10

) capable of emitting visible light of varying wavelengths is also disclosed.
