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.
The second slider image above shows process non-uniformity with and without Intelligent | Pixel. This technology:
The third slider image above shows how the application of IGNIS Intelligent | Pixel and Stability | Control technologies compensate for all threshold voltage shift, making the backplane perfectly stable over time.
The fourth slider image above shows how Intelligent | Pixel removes brightness variation with temperature variations.
