An organic LED display exhibiting pure RGB colors

Abstract A full color 5.2-in. 1/4 video graphics array (VGA) passive-matrix organic light emitting diode (OLED) display has been developed. The display features 320 (×3)×240 pixels with an equivalent pixel size of 0.33×0.33 mm 2 , white peak luminance of over 150 cd/m 2 , and power consumption of 6 W. It uses a cathode patterning method with electrically insulated cathode separators and an RGB emitters selective deposition method with a high accuracy mask moving system. Furthermore, we have achieved pure RGB colors as well as high luminance from the cells by applying the optical interference effects. The display can display high resolution video rate pictures with virtually the same quality as a CRT can offer.
