Japa Display shows off paper-like low-power reflective LCD

Posted on Tuesday, November 06 2012 @ 21:32:02 CET by

DigInfo TV published a video of a new paper-like low-power color reflective LCD screen made by Japan Display. The display has good visibility in sunlight and can show video.
Japan Display has developed two versions. The first is highly reflective, with a reflection rate of 40%, and 5% coverage of the NTSC color gamut. The second has high color purity with 36% coverage of the NTSC color gamut, but its reflection rate is 28%, making it slightly dimmer. Both types have a contrast ratio of 30:1, and power consumption of 3 mW when showing still pictures.

"This display is a reflective type, but as it uses liquid crystal, it has electric circuits built in. The circuits can retain signals. This feature is called Memory in Pixels. With a still picture, once the data has been written, it can be retained, so power consumption is extremely low."

"Here, we're presenting two displays, a conventional version and a type with high color gamut. For the conventional version, the technology has already been proven, so we can mass-produce this right away if customers require it. The type with high color gamut still has a few issues which we need to overcome. But we would like to discuss this type with customers when the technical issues are sorted out."
