Kitchener, Canada – May 18, 2011 – IGNIS announces a 3.47” 320 × 480 pixel AMOLED display, manufactured by RiTdisplay Corporation, and built with IGNIS patented AdMo™ compensation technology which makes the display more stable and more uniform. The display is ideal for mobile phones and other portable applications that require the bright image, rich colours, ultra-high contrast, and lower power of an AMOLED display. IGNIS and RiTdisplay will be demonstrating the product at booth #728 at SID Display Week 2011, from May 16-20 in Los Angeles. 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 it’s used to make most of the world’s LCD displays. Compared to polysilicon it’s highly uniform, less expensive, and represents 95% of the world’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 performance is equivalent to polysilicon AMOLED. The product also incorporates IGNIS’ latest all-in-one driver chip for amorphous silicon AMOLED, which is the first of its kind in today’s AMOLED market,” says Paul Arsenault, President & CEO. “This opens the door for RiTdisplay and other…

One of the problems with some AMOLED backplanes is short-term image sticking. If a user puts an image on the display and leaves it on for a minute or so, then tries to change the image, the original image will be “stuck” for several seconds. This is due to a hysteresis effect in the TFTs (thin-film transistors). We’ve made some videos of an AMOLED display with MaxLife™ technology, at various temperatures, showing no hysteresis effect.
