Abstract
An integrated organic light emitting diode (OLED) color display device is disclosed. The OLED display device comprises at least one pixel element ( ) capable of emitting visible light of varying wavelengths. Pixel element ( ) may comprise: a substrate ( ), an addressable two-dimensional matrix of organic light emitting diodes ( ) that emits monochrome light, a color conversion matrix element ( ) capable of absorbing the monochrome light and re-emitting that light at different wavelengths, and cover element ( ). Color conversion matrix element ( ) may further comprise at least one red color converting subelement ( ), at least one green color converting subelement ( ), and at least one blue color converting subelement ( ). The color converting subelements ( , and ) may further comprise semiconductor nanocrystals ( ) uniformly dispersed in a transparent organic binding material ( ). The size distribution of the semiconductor nanocrystals ( ) may be precisely controlled to define the capability for color conversion to a particular wavelength of re-emitted light. The color conversion matrix element ( ) 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 ( ) capable of emitting visible light of varying wavelengths is also disclosed.
