25‐2: Subpixel Optimization in AMOLED Displays by Self‐assembled Patterning of a Secondary Cathode

“…Unlike the differentiated CPL thicknesses for subpixels with different colors that can be achieved by evaporation of second or third layer with fine metal mask (FMM) in mass production line, the cathode cannot be evaporated directly with FMM due to the incompatibility of FMM to the high process temperature of metal evaporation. [2,3] Therefore, regardless of the potentially much bigger device performance and design freedom increase, the differentiated cathode concept has not yet been adopted in mass production of AMOLED. Recently, we have successfully commercialized our mass production compatible Cathode Patterning Material (CPM), [4,5] which is used to pattern the cathode for the Under Display IR sensor (UDIR) and Under Panel Camera (UPC) applications.…”

The effect of transmittance and luminous efficiency with the application of cathode mesh mask in transparent organic light‐emitting devices

“…Thus, it is necessary to achieve the transparency of electrodes, in the meantime, to ensure the brightness and efficiency of the device. To be more specific, this article focuses on not only new materials, but also breaking through other bottlenecks, such as the improvement of preparation process …”
