    • A tuned OLED device includes a microcavity structure including a light-emitting layer for producing light, a semitransparent reflector, and a reflector layer disposed on opposite sides of the light-emitting layer, the microcavity structure enhancing on-axis light produced from the light-emitting layer in at least one particular wavelength to produce a desired on-axis viewed color while not substantially enhancing on-axis other wavelengths of such light; and a layer including a color change medium which is responsive to wavelengths of light shorter than the particular wavelength by absorbing such shorter wavelengths of light and emitting light corresponding in color to the particular wavelength, thereby improving the color of the light produced by the OLED device when viewed in an off-axis direction.
    • 调谐OLED器件包括微腔结构,其包括用于产生光的发光层,半透明反射器和设置在发光层的相对侧上的反射器层,微腔结构增强从发光层产生的轴上光, 至少一个特定波长的发光层以产生期望的轴上观察颜色,同时基本上不增强这种光的轴上其他波长; 以及包括颜色变化介质的层,其通过吸收这种较短波长的光并且发射与特定波长相对应的颜色的光来响应于比特定波长短的光的波长,由此改善由OLED器件产生的光的颜色 当从离轴方向观察时。
