一个独立控制的，三色，有机发光器件的垂直堆叠的像素架构，允许独立调谐的颜色，灰度，和强度。12层器件结构由依次堆叠的金属氧化物、非晶有机物、结晶有机物和金属薄膜层组成，所述金属薄膜通过热蒸发和射频溅射的组合沉积。三种可寻址颜色中的每一种对于平板视频显示应用都足够亮。堆叠中的中间器件采用了一种新颖的倒置结构，以降低复合像素的最大驱动电压。
An independently controlled, three-color, organic light-emitting device was constructed with a vertically stacked pixel architecture that allows for independent tuning of color, gray scale, and intensity. The 12-layer device structure consists of sequentially stacked layers of metal oxide, amorphous organic, crystalline organic, and metal thin films deposited by a combination of thermal evaporation and radio-frequency sputtering. Each of the three addressable colors is sufficiently bright for flat panel video display applications. A novel inverted structure is used for the middle device in the stack to lower the maximum drive voltage of the compound pixel.
