Paper Abstract

When a plastic substrate is under a highlight, the reflected light on the substrate always dazzles the observer. To prevent the effect, anti-reflected (AR) coating is applied. However AR-coating is difficult to be designed with wide wavelength range. In this research, the discontinuous metallic films were fabricated on the plastic substrates to reduce the reflection of the plastic substrates with wide wavelength range. To reduce more reflectance, the discontinuous metallic film can also be applied as the mask of selective ion etching to achieve rough surface. The results show the average reflectance of the AR-coating on the plastic substrates has been decreased 5%. The average transmittance has been increased 3%.
