Japan Display, a leading supplier of small- and medium-sized displays, has begun to mass produce its IPS-NEO display panels for mobile products. IPS-NEO displays offer high contrast and high image quality favourable to medical and other industrial applications.

Liquid crystal panel manufacturing requires an orientation process that aligns liquid crystal molecules in a uniform direction. Generally, the rubbing method, as portrayed in the diagram below, is employed. In this process, an orientation membrane is rubbed in a fixed direction with a rubbing roller with cloth wound on it. With this method, unevenness of the circuit pattern formed on the glass substrate could impede proper orientation and the involvement of foreign particles in the rubbing process may affect the production yield. Adopting JDI’s photo alignment method, IPS-NEO is free from these issues and achieves a higher contrast, superior viewing angle characteristics and an improved production yield.

Products adopting high resolution formats have been spreading in recent years. As their pixel sizes get smaller, transmissivity tends to be poorer and backlight power consumption to be higher. In contrast, JDI's photo alignment method paves the way for the use of highly transmissive liquid crystal, traditionally regarded as difficult to mass produce. That helps increase transmissivity by at least 10% and contributes to reduced power consumption.

JDI's sixth-generation (1500*1850mm glass substrate) low temperature poly-silicon (LTPS) line in its Mobara Plant (Mobara-shi, Chiba, Japan) is now ready for mass production of IPS-NEO. In the future, JDI will be steadily introducing and expanding it to other lines.

Sigh. LCD is a monster that just won't die.

It's not a bad technology, if they just improve the blacks, the viewing angles, increase the aperture ratio, and improve pixel transition speed.

That photo is a lie. IPS is decent in side angles.
