TFT-less IR-driven OLED Display

BACKGROUND TV screen sizes are getting bigger and bigger every year. However, manufacturers using organic light-emitting diode (OLED) technology face a big challenge in fabricating TV screens over 100 inches at reasonable cost. Unlike the OLED process which is compatible with low-cost, low-temperature, and large area processing methods including...
