Letter: Novel approaches to realize high-resolution AMOLED display

摘要

Two different approaches to realize high-resolution active-matrix organic light-emitting device (AMOLED) display were delivered. By adopting specific organic light emitting diode (OLED) structure with pre-pattern electrode and the utilization of color filter, we successfully simplify the fabrication process with fine metal mask (FMM)-free or one-FMM solutions. Each approach was demonstrated with a 4.4" panel with 413 ppi pixel density based on real stripe RGB. Both panels possessed low power consumption, low reflectivity, and superior NTSC performance. Because the utilization of FMM was avoided or reduced, higher production yield, higher throughput, and lower cost could be achieved. Therefore, these two approaches are very promising for mass production of high-resolution AMOLED display.
