In the transparent OLED displays, both characteristics for optical and thermal uniformity are strongly required. To realize high thermal conductivity with low loss of transparency, we proposed and optimized a thermal-conductive sheet structure. After fabricating the sheet, the optical and thermal characteristics were evaluated experimentally to confirm the effectiveness of new proposed thermal-conductive sheet in the transparent OLED displays.
