Demonstration of color filters for OLED display based on extraordinary optical transmission through periodic hole array on metallic film

Abstract

By optimizing critical parameters including period, thickness, hole shape and diameter, a tri-color filter based on extraordinary optical transmission through periodic hole array on metallic film is designed for OLED display, which shows high purity, narrow bandwidth and large resonant peak in simulation, and experimentally study. Also, its practicability gets confirmed by further verifications in structure’s angle invariance, oblique incidence transmission efficiency and polarized incidence independence. The 0.2 × 0.2 mm 2 tiny fabrication scale and as more than 360 periods array dense qualify for UVGA (1600 × 1200) resolution.
