为了制作全色有机电致发光显示器，传统上需要三个精细的金属荫罩(FMM)来图案化红色、绿色和蓝色发光层。在这项工作中，通过将蓝色发光层安排为所有子像素的共享层，我们证明了可以通过两个FMM工艺来实现全彩色显示，从而与传统方法相比减少了一个FMM工艺。尽管减少了一次FMM过程，但可以独立地优化红色、绿色和蓝色亚像素。此外，红色和绿色亚像素的性能不会因共享的蓝色发光层而降低。由于省去了一个FMM，工艺触觉时间、掩模成本和对准误差都可以减少，从而降低了全彩色有机电致发光显示器的制造成本。(C)2011爱思唯尔B.V.保留所有权利。
To make a full color organic electroluminescent display, conventionally it requires three fine metal shadow masks (FMM) to pattern the red, green and blue light-emitting layer. In this work, by arranging the blue light-emitting layer as a shared layer for all sub-pixels, we demonstrate that a full color display can be achieved by two FMM processes, thus reducing one FMM process compared to conventional method. The red, green and blue sub-pixels can be optimized independently despite the reduction of one FMM process. Also, the performance of the red and green sub-pixels is not degraded by the shared blue light-emitting layer. Due to elimination of one FMM, the process TACT time, mask cost and alignment error can all be reduced, thus cutting down the manufacturing cost of full color organic electroluminescent display.
