Architecture the LCD Panel.The LG IPS Way


New Delhi, Delhi, India, Monday, August 30, 2010 -- (Business Wire India) -- LCD (liquid crystal display) monitors come in several architectures. One term you may see is TFT (thin film transistor) LCD. Thin film technology improves image quality and is used in all high quality computer monitors.

In addition to TFT, other terms you may see are TN, VA, and IPS.

TN (twisted nematic) technology is the most basic LCD architecture. However, TN panels are not the best for photo editing due to a limited viewing angle,(meaning that the color and contrast change fairly dramatically if your viewing angle is not dead center), and low bit depth (6-bit depth is typical).
VA (vertical alignment) architecture is an improvement over TN with improved viewing angles and support for 8-bit depth., There are several variations such as MVA (multi-domain vertical alignment), PVA (patterned vertical alignment) and ASV (advanced super view).

IPS Panels Are The Best For Photo Editing

VA architecture and its variants are an improvement over TN, but arguably the best architecture for high quality displays, (the type required for accurate photo image editing) is the IPS (in-plane switching) architecture. There are now several variants of the in-plane switching as the technology continues to advance.

These are the key advantages of IPS architecture.

1. True wide viewing angle: Accurate and consistent colors at any viewing angle
2. Real color: IPS reproduces images that are closest to the actual color ( original image = digital camera = IPS monitor)
3. Eye comfort: Less eye strains compared to VA, TN
4. Stable quality: Image onscreen is designed to remain stable when you touch the screen

Many professional IPS based LCD monitors also feature high bit-depth and ultra wide color gamuts, which we define as equal to or greater than the Adobe RGB (1998) color space.

One interesting variation of IPS is the AH-IPS architecture developed by LG Display. This type of IPS panel uses the AFFS (advanced fringe field switching). This architecture gives the best performance for smaller screens with high resolution such as those used in handheld devices such as the Apple IPad.

AH-IPS has the advantage of greater light transmission, which translates into lower power consumption. So far, this technology has been limited to small screens due to higher manufacturing costs for larger screens.

About IPS:

IPS (In Plane Switching) technology is one of the most leading LCD technologies in the world. IPS technology innovatively aligns liquid crystal horizontally to increase the viewing angle and changes the LCD transmittance. IPS is mainly owned by LG Display Company. This technology was unanimously accepted in its early phase by professionals from all across the globe.

IPS enabled LCD TV particularly deserves praise on its dynamic image expression in comparison to Normal LCD TV, because the IPS liquid crystal responds faster and expresses smoother moving images. While ensuring the image sharpness, IPS is more suitable to viewing dynamic images such as the Olympic Games and can entirely satisfy consumer needs for high definition images.

About LG Display:

LG Display Co., Ltd. (NYSE: LPL, KRX: 034220) is one of the world's top maker of TFT-LCDs with 24.7 percent global market share in the fourth quarter of 2008*. LG Display currently operates eight fabrication facilities in Korea and four back-end assembly sites in Korea, China and Poland. The company has a total of 25,000 employees operating worldwide. LG Display is a leading developer and manufacturer of LCD panels for notebook computers, monitors and TVs. Other manufacturing areas include panels for consumer devices such as portable media players, cellular telephones and GPS navigation systems, as well as panels used in the medical and aerospace industries.
