Hitachi Displays exhibits a MEMS (Micro-Electro-Mechanical Systems) Display at the CEATEC 2010 show in Japan. The MEMS display prototype is based on the Pixtronic MEMS technology. MEMS displays use about half the power of LCD based displays and still produce vivid colors. The MEMS display shown at the CEATEC has a 2.5-inch size and QVGA resolution.
Another cool thing about MEMS displays is that they can be operated in reflective, transparent or semi-transparent mode. Hitachi plans to release MEMS displays for mobile phones and Tablets starting at the end of 2011. Just imagine a Tablet that can be switch to transparent for some cool augmented reality apps - The CSI show would love it.
