1An OLED (organic light-emitting diode) layer that emits light.
2A backplane, 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, but 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.
The 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.
So 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.
- Compensates for all types of mura (dot mura, line mura, cloud mura, etc).
- Compensates for both threshold voltage and mobility variation
- The superior compensation enables even an unmodified polysilicon process (designed for AMLCD) to make highly uniform AMOLED panels.
- Compensates for all threshold voltage shift, making the backplane perfectly stable
- Removes brightness variation with temperature.
