In-Plane Switching (IPS) technology acts on the liquid crystals inside an LCD, so when voltage is applied, the liquid crystal rotates in parallel (or in-plane), allowing the light to pass through instead of turning upright. This behavior of the crystals significantly improves many viewing aspects of the display.

Compared to regular TN panels, IPS is superior in color, viewing angles, and these TFTs can even handle direct sunlight due to their high brightness.
