Paper-Like, Low Power LCD from Japan Display Plays Color Video

Japan Display has developed a video-playing paper-like LCD that runs on low power. “The results could be of great use to device makers who want to simulate a paper-like experience while adding the capabilities of color video,” writes Technology Review.
A press release from Japan Display notes that “an optical property optimization adopting a newly-developed scattering layer” and a low power consumption method are integral aspects of the technology.
The technology’s Light Control Layer does not reflect light like most LCDs, but rather “the display collects light to some extent, in the direction of the user’s eyes, making it look similar to paper,” according to Japan Display.
The lower power consumption comes from the company’s Memory in Pixels technology. This technology retains signals when it displays still pictures, which saves energy.
Japan Display has developed one version of the technology that is bright, but has relatively low color purity, and another version that is dim, but has high color purity. The company is ready to market the bright, low color purity model, while it continues research and development on the high color purity display.
