Abstract

Recently, microcavity is studied to reduce the optical loss of BLU and OLED. In this paper, we suggest applying microcavity to photo-luminescent lamp with plasma discharge technology to meet the display applications for a BLU for LCD. The structure of photo-luminescent lamp consists of SUS foil and ITO glass with microcavity. The opto-electric characteristics of photo-luminescent lamp with microcavity was evaluated. The brightness of photo-luminescent device was increased over $111cd/m^2$ with the adaptation of patterned microcavity at $30{\mu}m$. The 3D optical simulation verified the enhanced light outcoupling when microcavity applied to the device.
