LG’s IPS technology makes viewing a pleasure as consumers can now get a vivid and clear picture on their screens. In Plane Switching (IPS) technology - one of the world’s leading LCD technologies – not only innovatively aligns liquid crystal technology to increase the viewing angle but also ensures vivid and clear moving images because of excellent Moving Picture Response Time (MPRT) performance and variation. The touch panel is also vastly stable as moving picture image sticking does not occur.
Developed in 1996, IPS was initially meant to improve on the poor viewing angle and the poor color reproduction of twisted nematic (TN) panels at that time. Its name comes from the main difference from the TN display, with the crystal molecules moving parallel to the panel plane instead of moving perpendicularly. This change reduces the amount of light scattering in the matrix, which gives IPS its characteristic wide-viewing angles and good color reproduction. The technology also reduces image distortion because of a fast and stable response time. It is pertinent to note here that the IPS panel gets it stable and accurate touching from its liquid crystal (LC) molecules’ structure. The LC alignment in IPS mode is horizontal, an advantage for the LC does not move far from the original position even when touched, while the LC alignment in normal panels is vertical, therefore, easily scattered.
The IPS panel is hard. Its horizontal switch molecular arrangement does not change even on being knocked. When the IPS panel is pressed down, the original colours remain, with some change of brightness. Thus, comparing with the vertical arrangement made by the VA LCD technologies, the molecule reducibility of IPS technology is more powerful, and its panel is more stable and durable.
With a stable touch panel that the technology offers, IPS panels promise a truly world-class viewing experience. With no colour distortion from any angle because of no shift in gamma rays, IPS technology panels are least strenuous to human eyes.
IPS is also the main hardware of the iPads that have been launched recently. Apple endorses IPS technology for it is a premium display technology. IPS panels are preferred for their superior true color values, the most consistent image, a stable touch panel and a superior viewing angle as compared to other LCD technologies. A large, high-resolution LED-backlit IPS display and an incredibly responsive multi-touch screen, have made the Apple iPads popular amongst consumers. Apple prefers IPS technology as the panels have several advantages over conventional panels that use TN (twisted nemantic) and VA (vertical alignment) display technologies especially when it comes to stable touch panels.
IPS LCDs meet the requirements of the sectors and professionals in the fields of design, medicine, print and space, etc. Graphic designers, major medical equipment makers like GE Medical, Philips Medical National Display prefer IPS panels. In fact, not only the professional sector, the home electric appliance sector has also applied IPS LCD for the unique advantages. It is known that the reason for the professional favor of IPS LCDs is the advantages of dynamic definition, color reducibility, visible angles and most importantly the touch panel which is vastly stable because moving picture image sticking does not occur.
