Oleds On Flexible Substrates, Chamika M. Hippola

Creative Components

In some applications flexible plastic substrates are advantageous over glass substrates for organic light emitting diode (OLED) fabrication due to properties such as higher refractive index, ease ofnano-patterning for enhanced extraction of light generated in the OLED, and promise in wearable electronics and biochemical sensing. Defects, impurities, and in particular sharp edges that may be formed in patterned plastic substrates such as polycarbonate (PC) can lead to catastrophic shorts when biased due to very high local electric fields. This work evaluated various PC substrates and their treatment with the goal of identifying the best substrates for patterning for enhancing OLED ...
