IPS (In-Plane Switching) is a technology used for LCDs. It was designed to overcome the main limitations of normal TFTs TN-matrices: relatively slow response times, small viewing angles and low quality color reproduction. PLS (Plane to Line Switching) is a type of IPS screen developed by Samsung, which has increased brightness and lower production costs.

5.every pixel has three subpixels
