We have developed highly transparent color liquid crystal display (LCD) using newly developed scattering‐type liquid crystal, which shows transparent state when voltage is not applied, with field sequential color (FSC) driving method without employing color filter and polarizer. Furthermore the light is directly introduced to the panel glass substrates from the edge of the substrates (not from back surface). At surface of the substrates, the light takes a total reflection by difference of refractive index between glasses and air. So the light propagates through the substrate. On the other hand, when a voltage as higher than a threshold voltage (Vth) is applied to liquid crystal (LC) layer, the light is scattered towards the viewers. This newly developed display has high transmittance (80%), wide color gamut and fast response time.

We have developed a new high resolution glasses-less 3D LCD with head-tracking technology. The 3D crosstalk has been suppressed to less than 2% at any position of the viewer by applying a fine pitch barrier and proper aperture design to the display.

We have developed an in‐plane switching (IPS) liquid crystal display with a fast response time that is three times faster than that for the comparable optical performance in the conventional IPS mode. The elastic energy function under the electric field is also analyzed.

SummaryTo exceed the top-level fuel efficiency of the 2009 Prius, a new motor was developed for installation in compact class hybrid vehicles including the new Prius. For the stator, segment coil stator with distributed winding was developed and achieved weight reduction and copper loss reduction. As for the rotor, highspeed, low-loss rotor was developed and achieved size reduction and volume of magnet used was reduced.Also, the motor cooling system was newly designed to improve the motor cooling performance. This paper describes the features of the new motor for the compact class hybrid vehicles including the new Prius.
