Key information on IPS screens
IPS - Also known as
AAS/ADS/AHVA or FFS/UWVA/PLS
IPS screens are specially designed to solve the problems one often associates with standard TN, (twisted nematic field effect) screens, such as limited viewing angle ranges and a low quality colour schemes. Within this article, we explore the advantages of using an IPS display.

Accurate colour representation
Capable of representing colours in a more vivid and accurate manner, IPS displays are commonly found in top of the range laptops and tablets. To illustrate, IPS screens are fitted in the iPad 3 and 4. Ideal for individuals who enjoy playing vivid computer games and kicking back with a high quality film, IPS displays are often thought to be of better quality than standard TN panels.
The science
So, how do IPS displays create this markedly different, (and improved) effect? The answer lies in the minute construction of the panels themselves. Whilst the liquid crystal molecules within standard TN displays sit in vertical relation to the screen, the liquid crystal molecules in IPS panels are designed to orientate themselves horizontally. The IPS crystal molecules are subsequently held in place by an electrical current supplied by separate electrodes, a mode of design which allows the molecules to shift within the display.
Cons
Whilst IPS screens are capable of displaying accurate colours, they tend to use a great deal more power than standard TN screens. Further, when compared with normal TN displays, IPS response times are slightly slower. What's more, whilst IPS screens are capable of presenting high quality images it is vital that you purchase a high end machine to avoid experiencing common display-based problems such as ghosting.
