This low power consumption OLED display shows a 25% reduction in energy use through multi-domain segmentation, indicating its potential for large displays.
A 13.2 inch low power consumption‐organic light emitting diode (OLED) display panel based on multi‐domain segmentation technique is demonstrated. Our OLED display panel is composed of 48 segmented zones, and ELVDD line networks in each zone are spatially separated. Through this particular architecture of the backplane, three different levels of ELVDD voltage are selectively applied to each zone according to the analysis data of the displayed image in the zone. The power consumption of our panel is reduced by up to 25% compared to the normal conventional OLED display panel by decreasing the applied ELVDD voltages locally. Our multi‐domain segmentation technique is very promising for large‐format displays such as IT devices, TVs, and automotive displays for the next generation due to its excellent energy efficiency.
