The IPS (In-plane switching) screen technology used for LCD (liquid crystal displays), and it was originally invented by Hitachi in 1996.
This technology is designed to solve the limitations of traditional LCDs (such as TN twisted nematic field) for example strong viewing angle dependence, high response time and low-quality color reproduction.
Most people aware of what it is and how good can be an IPS display when they use Apple iPad.
In-plane switching (IPS technology) contains arranging and switching the liquid crystal molecules layer between the glass substrates, this is done in a plane parallel to these glass plates.
The hugh advantage of an IPS monitor is the wide viewing angles, that’s why colors stay true and it is not depend on what angle you view it from.

Types of IPS panels
This a very confusing question, because IPS has very wide-range of types and panel names, but the names of the panels technically means the following:
This is the cheapest IPS panel, and that’s why it is very popular. e-IPS panel color gamut is not as good as H-IPS or P-IPS, but much more better than TN panels. Usually e-IPS monitors advertised like an 8 bit monitors with 16.7 million colors, but the least expensive displays have just 6 bit color palette.
The “h” in the name means horizontal. This is the most modern IPS panel, the pixels are in straight vertical lines with a slightly smaller electrode width. The Latest IPS monitors are manufactured in this format with horizontal IPS pixels positioned in vertical lines.
The “p” means professional – this type of an IPS panel has wider color gamut. A lot of manufacturer claims that this type of monitors have 10 bit color palette with 1.07 billion color, but just a very few capabable to do it truly. A lot of p-IPS has 8 bit color palette with AFRC modul which is simulate the 10 bit palette.
