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

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."
