What is IGNIS AdMo-p™?
AdMo-p™ technology compensates for backplane non-uniformities
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.
Polysilicon backplanes don’t provide uniform current because of manufacturing non-uniformities. Without IGNIS technology, the TFT circuits will provide different current to the OLEDs, which results in lines, spots, and cloudy areas known as “mura”.
IGNIS AdMo-p™ technology uses a patented TFT pixel circuit and driving scheme to compensate for the non-uniform backplane. 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, mura-free images.
AdMo-p™ technology compensates for temperature changes
Enables 330ppi AMOLED backplanes
- Small circuit with only 3 TFTs enables 330ppi AMOLED displays.
- Compensates for all types of polysilicon mura (dot mura, line mura, cloud mura, etc).
- Also compensates for IR drop, hysteresis, Vt shift and temperature.
- 4μs programming time.
- Standard driving waveforms (driver may need to be modified to support modified timing).
HR Pixel Structure
Enables evaporated OLED at 330ppi
IGNIS’s patented HR (high-resolution) pixel structure lowers the shadow mask complexity by approximately 1/3. Therefore a 330ppi shadow mask is possible, and is effectively the same complexity as a 220ppi shadow mask using conventional RGB stripe layout.
- Uses three subpixels per pixel.
- No effect on text or line resolution.
- No custom driver or subpixel rendering is required.
- Together with IGNIS’s AdMo-p™ pixel circuit, enables 330ppi AMOLED displays using today’s existing technology.
