Intelligent | Pixel technology solves TFT uniformity and aging, solves OLED uniformity and voltage shift and enables 330ppi display production.
AMOLED displays have two main layers:
An OLED (organic light-emitting diode) layer that emits light.
A backplane layer made of TFT (thin-film transistor) circuits that provide current to the OLEDs, thereby controlling their brightness.
Some backplanes age non-uniformly and some are not uniform when they’re made. Either way the result is the same – the TFT circuits provide different current to the OLEDs, causing visual artifacts like image burn-in, spots, lines, and cloudy areas.
IGNIS Intelligent | Pixel is a family of pixel circuits that compensates for anything that affects TFT performance, such as process non-uniformity, hysteresis, TFT instability, and variations due to temperature. All compensation takes place inside the pixel, so no external components are required.
With Intelligent | Pixel technology the TFT circuits always provide uniform current to the OLEDs, even though the TFTs themselves aren’t uniform. This means the AMOLED display will always show smooth, defect-free images.
IGNIS Max | Life technology is an enhancement to our Intelligent | Pixel technology. Similar to Intelligent | Pixel, Max | Life solves TFT uniformity and aging, solves OLED uniformity and voltage shift and enables 330ppi display production. In addition, this technology solves OLED efficiency loss and improves power consumption.
Both layers are often non-uniform, which results in lines, spots, and cloudy areas known as “Mura”. As well, both layers can age non-uniformly, which results in burned-in images. Max | Life compensates for the OLED material aging, and provides extra TFT compensation for demanding applications.
It does this by measuring each TFT circuit and each OLED element in the display during operation, and uses that data to correct for non-uniformity and aging. This means the display will always show smooth, Mura-free and burn-in free images over its’ entire lifetime – up to 75,000 hours
IGNIS Max | Life Inspection is a factory-calibration system for all AMOLED displays. Comprised of a combination of hardware and software, it scans the TFT backplane and OLED devices using Max | Life technology. The system can pinpoint the location and type of defects, collect data about the process, and measure non-uniformity which can be used to compensate to improve image quality.
