The IPS (in-plane switching) LCD is a horizontal electric field type LCD created by Hitachi. The simple movement of liquid crystal elements revolving in parallel with the glass substrates has realized this wide viewing angle LCD, where changes of color tone due to the viewing angle or gradation are so slight that the natural picture can be seen from any angle vertically or horizontally. The AS-IPS technology modified for TVs has improved the aperture ratio by approx. 30% compared with conventional products to produce higher brightness. It also features improved color reproducibility.

Overview |
It is fundamentally a wide viewing angle according to simple movement that the
liquid crystal molecule rotates in parallel to the base.

Feature |
The IPS technology was put to practical use in 1996. The IPS-Pro technology has improved the permeability by approx. 1.5 times, contrast ratio by approx. 3 times. The world best performance is possessed.
