Manufacturing of active matrix OLED full color displays has begun at SK Display; a joint venture between Eastman Kodak Co. and Sanyo Electric Corporation. The manufacturing process is based on vacuum deposition of organic materials to form thin emissive layers of OLED films patterned to emit red, green and blue light. A number of innovations have enabled mass production including the development of linear sources, precision shadow mask technology, white emitter with color filter array, and sealing and desiccant technology. The first product is a 2.2 inch diagonal panel full color panel with 521 x 218 dots. A technology demonstration project was recently done on the manufacturing line to make a 15 inch diagonal 3840 x 720 dot HDTV format display with exceptional viewing qualities.
Recent experiments that measure the effects of the photoinduced generation and transport of charge on the refractive index of polymeric films having a second-order nonlinear optical response are reported. Two approaches were taken to observe these effects. In the first approach, the photoconductive and light refraction processes were separated by confining these functions to separate layers in a multilayer structure. In the second approach, photoconduction and refraction functions were combined in the same layer. The modulation of the refractive index was then measured in response to photoconductions.
