An in-plane switching (IPS) display is a type of LCD panel used in the manufacture of monitors, phones and tablets, among other devices. It differs from less-expensive technologies, such as twisted nematic (TN), in that it offers better colour reproduction across wider viewing angles. However, some TN panels can offer faster response times, which are favoured by gamers who want blur-free high-speed action. Other technologies include PLS (Plane to Line Switching), from Samsung, and vertical alignment (VA).
