Low-Power-Consumption Organic Light-Emitting Diode Display Based on Locally Driven Multi-Domain Segmentation

Description:

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 its displayed image. 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 of the next generation due to its excellent energy efficiency.
