Ignis' 55" OLED TV samples arrive, company says their technology enables lifetime and efficiency boost
Last month Ignis Innovation announced that they began producing some 55" OLED TV evaluation samples for display makers to test their MaxLife compensation technology. The company now tells us that the first sample panel arrived at their offices, and they will start fulfilling orders (to display makers and OEMs) in about two weeks.
The company did some initial measurements, and they say that this panel offers the world's lowest power consumption (20% lower than LG and Samsung's current OLED TVs), longest lifetime (a significant boost over existing OLED panels). The panels are highly uniform (much better than the OLED TVs no the market).
The MaxLife external compensation technology continuously measures every pixel in the display and compensates for even the smallest shift in performance (due to burn-in or bad manufacturing issues), making it completely uniform and completely stable. MaxLife can work with a-Si, LTPS and metal-oxide backplanes (the 55" panels produced now use a metal-oxide backplane).
Besides the benefits listed above, Ignis says that MaxLife will improve production yields (and so lower production costs) and also offer an easy migration to high resolutions (UHD) due to the simple pixel design.
For those not following the Ignis Innovation technologies, here's a summary:
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)."Edited by Rich Peterson - 10/16/13 at 7:48am
