Are you aware of IPS Panel Technology? IPS (in-plane switching) technology is the best type of Panel Technology available today in the market for the manufacturing of LCD. When you buy a LCD monitor you never know what type of panel technology has been used in that monitor because the specification list does not mention the type of panel used in that LCD by the manufacturing company. It's not the price that matters while you buy the LCD monitor, you should know about the benefits of the panel type in that particular brand of LCD before you buy it.
The Thin Film Transistor (TFT) technology is widely used by the manufacturers of LCD monitors which improves the quality of the image. IPS is the nickname of this TFT technology. The specifications and details of IPS Panel Technology are considered best for high accuracy in colour, its quality image and wide viewing angles. Various types of panels are available in the market at present and the most advanced being IPS but at a price. But who would not want a wide angle view which is an absolute treat after TN matrices and not to mention the high colour reproduction. The IPS (In Plane Switching) was developed by one of the most famous companies of Japan in 1996 to solve the problems of TN-matrices. IPS is now-a-days widely used technology by the manufacturers of LCD monitors other than the technologies like TN Film, MVA and PVA. The other panels may be popular within some users though they are inexpensive. But if you compare the IPS panel technology with other panels, you will find the colour reproduction and viewing angle more advantageous. The response time is excellent which makes them ideal for fast gaming. Used in 22" monitor which is a size popular among consumers.
Being the excellent panel technology S-IPS/H-IPS panels are also expensive but they offer excellent picture reproduction and suitable for graphic work, web browsing and also other applications.
Compared to TN panel, the reason for improved wide angle display and colour reproduction in IPS panel is because the molecules forms the helix shaped structure are used which makes the angle form freely while the pixel is left by the light. Initially the result of IPS display was poor in regards to contrast ratio, but with the development of advanced IPS panel technology, the same has improved remarkably. The only drawback of IPS panel technology is the response time is very slow with about 50ms.
Each manufacturer has given different names to the IPS technology like Super IPS (S-IPS), Advanced Super IPS (AS-IPS), IPS Provectus (IPS-Pro), Horizontal IPS (H-IPS) and Enhanced IPS (E-IPS). There are different types of advantage from each of these technologies. You need to decide what advantages you expect from the LCD monitor you buy by surfing through the net and collecting information for each popular brand, compare one with other and purchase one.
