Ultra Low Power Consumption

Reflective-type Color Display

JDI carries out development relating to not only improvement of display performance with higher resolution and higher picture quality, but also to reflective-type color displays for realization of ultra-low power consumption.

JDI’s reflective-type display optimizes its optical design by using a newly-developed scattering layer. At the same time, ultra-low power consumption is achieved when still images are displayed by adopting a memory-in-pixel structure using low temperature poly-silicon technology. Full-color moving images are also available. This technology supports development of new applications like smart watches and e-readers.
