Fabrication of a Blue $M\times N$ Pixel Organic Light-Emitting Diode Video Display Incorporating a Thermally Stable Emitter

A 7 times 11 pixel blue OLED display was fabricated using a patterned indium-tin-oxide (ITO) substrate. The fabrication process for an M times N pixel organic light-emitting diode (OLED) video display including an electrical insulating layer and a physical pixel separator layer is presented. An efficient and thermally stable blue fluorescent organic material, 6,6'-bis((2-p -biphenyl)-4-phenylquinoline) (B2PPQ), was used in combination with an evaporated hole-transport small molecule with a high ionization potential.
