IGNIS has received firm orders for its 55” AMOLED Evaluation Platform
Waterloo, Canada – September 4, 2013 — IGNIS Innovation Inc. announces that it has received firm orders for samples of its 55” Full HD AMOLED display from display manufacturers and OEMs. The display is built using IGNIS’s patented MaxLife™ compensation technology and is designed for display manufacturers and OEMs who want to evaluate the performance of MaxLife technology for use in their own displays and products.
The major issues in large area AMOLED displays are cost and lifetime. The low yield, which is caused by complex pixel circuits and a high level of non-uniformities, results in a higher display cost. AMOLED displays can have non-uniformity patterns known as “mura”, resulting in stripes, speckles, or cloudiness in the display. This is due to the manufacturing process of both the Thin Film Transistor (TFT) and the OLED. The current solution is to use complex pixel structures (with multiple TFTs per pixels) known as In-Pixel Compensation (IPC). In addition to limited performance of IPC for non-uniformity compensation, the complex pixel structure results in a higher manufacturing defects and lower yield. Therefore, it is not practical to adopt such an approach for high volume large-area AMOLED displays. Moreover, achieving 2K x 4K AMOLED displays will be difficult with the complex pixel circuits. Thus, adopting a simple solution with high compensation performance is crucial to reduce the cost, increase the capacity with the limited fabrication lines, and achieve higher resolution displays.
In addition, AMOLED displays suffer from image sticking, where images can be permanently burned into the display. This is caused by the instability of both the TFT and the OLED which is a more serious issue at higher brightness and longer-running display operation.
“IGNIS MaxLife technology offers three major advantages over existing solutions: superb compensation capability for high degree of initial non-uniformity, comprehensive aging compensation, and detailed defect report for repair and tuning.” says Dr. Reza Chaji, President and CTO. “Despite its unique offerings, IGNIS MaxLife technology provides for a very simple pixel structure leading to even higher manufacturing yield and higher resolution (e.g. 2K x 4K).” he added. “IGNIS technology is a universal solution and has been manufactured and proven on oxide, polysilicon, and amorphous silicon TFT backplanes.”
