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…
