Ignis Innovations has announced the company has received orders for samples of its 55” Full HD AM-OLED display from display manufacturers and OEMs. The display is built using Ignis’s MaxLifetm compensation technology.
This sample is designed for display manufacturers and OEMs who want to evaluate the performance of MaxLife technology for use in their own displays and products.
Ignis Innovation 55-inch 120Hz AM-OLED is an evaluation platform, produced to demonstrate how Ignis’s MaxLifeTM and Intelligent PixelTM compensation technology enable large-sized AM-OLED displays.

According to Ignis Innovation their MaxLife technology aims to solve major issues in large area AM-OLED displays namely high cost and low lifetimes:
- High costs are due to low manufacturing yields which is caused by the need for complex pixel circuits to compensate for high levels of non-uniformities patterns known as "mura", resulting in stripes, speckles, or cloudiness in the display
- These non-uniformities are due to the manufacturing process of both the TFT and the OLED
- The current solution is to use complex pixel structures (with multiple TFTs per pixels) known as in-pixel compensation (IPC)
- The complex pixel structure results in a higher manufacturing defects and lower yield
- It is not practical to adopt such an approach for high volume large-area AM-OLED displays
- Achieving 2Kx4K AM-OLED displays will be difficult with the complex pixel circuits
- 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
- AM-OLED displays suffer from image sticking, where images can be permanently burned into the display - 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
Dr. Reza Chaji, President and CTO, said, "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." Reza Chaji, added, "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. 2Kx4K)."
