In-Plane Switching (IPS) is a liquid crystal switching technology that addresses the problems that affected early TFT-LCD panels many years ago, including limited viewing angles, color shift and slow response times. Thanks to the roll-out of successive generations of IPS technology, all of these issues are now largely in the past, and high-end LCD TVs that combine an IPS-based panel with premium set electronics truly deliver a superior viewing experience.
THE EVOLUTION OF IPS
The original IPS technology was developed some years ago by engineers at Hitachi as a way to overcome the poor viewing angle characteristics of early TFT-LCD technology. The basic principle was to change the physical behavior of the liquid crystal layer by having the molecules move in parallel to the TFT and color filter layers rather than at oblique angles. This fundamental change significantly lessened light scattering, and thus improved the picture uniformity and color fidelity when viewed from wide angles.
- Several years later, LG.Philips LCD introduced Super IPS (S-IPS),which built upon the strengths of IPS by employing an advanced “multi-domain” liquid crystal alignment.
- Enhanced Super IPS (Enhanced S-IPS) is the newest generation of IPS technology, and takes the LCD viewing experience to the next level.
Lava Mobile,one of the biggest Indian mobile brands, has launched a new touchscreen phone called the Lava A10, which features a 3-inch IPS (In Plane Switching) display.
