IGNIS will present its latest developments in AMOLED displays and how its technology can improve the yield at the OLEDs World Summit in San Francisco. IGNIS technology improves the yield and reduces the manufacturing ramp-up process resulting in lower cost high-volume large area AMOLED displays. In addition to improving the display quality and extending the display lifetime, it is also a great tool in developing new fabrication technologies. To hear more about this technology and its details, please attend our talk during the OLED World Summit.
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…
