IGNIS team celebrates shipping 55-inch AMOLED Displays to Customers

Dec 20 2013

The team at IGNIS Innovation Inc. is happy to announce that we have started shipping 55-inch AMOLED display samples to our customers! After demonstrating the 55-inch AMOLED displays at FPD International in Japan, IGNIS has received more orders for its display samples. Also as a result of showing how our technology can enhance AMOLED display QUALITY and LIFETIME and reduces the COST by boosting the yield, IGNIS has engaged with display manufacturers in designing and applying our technology to next generation products for TV, Mobile, and Tablet applications.

IGNIS Announces 20” AMOLED evaluation samples available August 2013

May 21 2013

Waterloo, Canada – May 21, 2013 – IGNIS Innovation Inc. announces samples of its 20” 1296 × 768 pixel AMOLED display will be available starting in August 2013. The display is built with IGNIS’s patented MaxLife™ compensation technology and is designed for display manufacturers who want to evaluate the performance of MaxLife technology for use in their own displays. Low-volume production runs of the display are also available for medical imaging, scientific imaging, and other demanding applications that require fast response time, wide viewing angle, and ultra-high contrast. Typically AMOLED displays suffer from image sticking, where images can be permanently burned into the display. This is caused by the instability of both the Thin Film Transistor (TFT) and the OLED. This isn’t a problem for mobile phones, which are replaced every couple of years. However larger displays are expected to have perfect uniformity over many years. AMOLED displays can also 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 TFT and the OLED. Currently the solution is to discard those displays with bad Mura. “IGNIS MaxLife technology continuously measures every pixel in the display and compensates for even the smallest shift in performance, making it completely uniform and completely…

IGNIS Launches Electrical Inspection System for AMOLED Display Manufacturing

May 20 2013

Waterloo, Canada – May 20, 2013 – IGNIS Innovation Inc. is pleased to announce the launch of MaxLife™ Inspection, an all-electrical inspection system for AMOLED display manufacturing lines. It provides detailed data on display defects which can then be repaired using a laser, improving yield 2-5 times. Flat panel displays are typically inspected with an optical camera. The precision is limited, and it only identifies a stuck-on or stuck-off pixel, but not the cause. MaxLife Inspection uses a probe card, custom measurement electronics, and MaxLife Viewer software to measure every pixel with 14-bit resolution. MaxLife Inspection can be used at two points in the manufacturing process: 1. First, the display is measured after Thin Film Transistor (TFT) fabrication but before OLED deposition. The software shows a map of the entire display, highlighting each defective pixel and its failure mode (gate-source short, open channel, etc.). This data is then used for laser-cutting or depositing new metal to repair the defect. 2. The system measures the display again after OLED deposition to identify OLED defects. That data can be used to repair shorted pixels and anode-cathode contact shorts. Line monitoring and process ramp-up is faster and more effective with MaxLife Inspection. Instead of taking random samples off the production line for measurement, The MaxLife Viewer software already…

New High Efficiency OLED Structure

Jul 11 2012

IGNIS is pleased to announce that our engineers have developed new bottom-emission OLED structure that provides similar aperture ratio as that of top-emission structure without the common electrode resistance issue. This structure can be a significant key to long-lifetime and low-power AMOLED TVs.

IGNIS MaxLife™ AMOLED TV Driver

Nov 28 2011

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 for >300ppi AMOLED display

Nov 28 2011

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.

IGNIS has developed a multi-functional display

Nov 28 2011

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.

MaxLife™ Hysteresis Videos on YouTube

Jan 03 2011

One of the problems with some AMOLED backplanes is short-term image sticking. If a user puts an image on the display and leaves it on for a minute or so, then tries to change the image, the original image will be “stuck” for several seconds. This is due to a hysteresis effect in the TFTs (thin-film transistors). We’ve made some videos of an AMOLED display with MaxLife™ technology, at various temperatures, showing no hysteresis effect.
