Until now, all AMOLED displays have been made with polysilicon backplanes, a higher-cost material. However amorphous silicon is an attractive material for AMOLED since itâ€™s used to make most of the worldâ€™s LCD displays. Compared to polysilicon itâ€™s highly uniform, less expensive, and represents 95% of the worldâ€™s manufacturing capacity for displays.
It was previously thought that amorphous silicon backplanes were unsuitable for OLED due to stability problems; however IGNIS technology has solved the stability problems, paving the way for this first product.
The IGNIS Innovation 3.47-inch 480×320 AMOLED display is the world’s first AMOLED display that makes use of an a-Si backplane. IGNIS will be showcasing its AMOLED display during SID 2011.
