IGNIS will be presenting a paper titled “Parasitic extraction challenges for display technologies and its applications,” at CDNLive Cadence User conference, on Wednesday March 14, 2012. www.cadence.com/cdnlive/na/2012/Pages/wednesday.aspx
IGNIS has developed and verified the second generation of its MaxLife™ driver IC for AMOLED TVs, monitors and tablets. Key features of this technology include: Corrects for aging and non-uniformity in both the backplane and the OLED. Resolves all image quality issues such as Mura, image sticking, and colour shift. Compatible with all backplanes (amorphous silicon, polysilicon, and oxide TFT), and all types of OLED (white with colour filter, evaporated, printed, etc.). Supports high resolutions, high frame rates, and 3D. With polysilicon or oxide TFTs backplanes, where uniformity is an issue, the yield can be improved from a few percent to an acceptable production level. With amorphous silicon backplanes, where aging and speed are an issue, it enables stable high-frame-rate AMOLED televisions.
IGNIS has developed technologies to push the conventional manufacturing techniques to >300 pixels per inch (ppi) AMOLED with true RGB pixels. Also, it has developed pixel circuit and driving scheme to compensate for the non-uniformity and enhance the lifetime of such a high-ppi display. These technologies can make AMOLED displays with similar resolution as IPS displays but with much better colour quality, higher contrast ratio, and wider viewing angle.
The major issue with AMOLED is the reflectivity which mandates the use of circular polarizer (reducing the OLED efficiency by 57%). IGNIS has developed a technique that not only removes the need for polarizer but also, the display acts as power scavenging device, touch screen, and self-calibration unit for non-uniformity/aging. Also, the manufacturing steps are not altered which results in the same yield and cost as normal AMOLED display with no-touch capabilities. IGNIS believes that this is a significant move toward adapting AMOLED display for tablet computers.
OLEDs experts from around the world will be gathering in San Francisco this September to share their collective knowledge and insight at the OLEDs World Summit 2011. IGNIS will be holding a workshop to review the challenges associated with the driving of active matrix OLED (AMOLED) displays.
IGNIS will be speaking on “Rethinking AMOLED Display Design” at the Emerging Displays Technology Conference, August 16 and 17, 2011. There are quite a few new options for making AMOLED displays, and new technology has changed some of the decisions that need to be made. We’ll be talking about how the critical choices affect different display specs, and some of the interesting products that can come out of this. AMOLED tablets? eBook readers? Television? YES!

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…
