IPS (In-plane switching) is a screen technology used for liquid crystal displays (LCDs). It was designed to solve the main limitations of the twisted nematic field effect (TN) matrix LCDs in the late 1980s. These limitations included relatively slow response time, strong viewing angle dependence and low-quality color reproduction. In-plane switching involves arranging and switching the orientation of the molecules of the liquid crystal (LC) layer between the glass substrates. This is done essentially parallel to these glass plates.
Advantages
-IPS panels display consistent, accurate color from all viewing angles. A state-of-the-art (2014) comparison of IPS vs. TN panels concerning color consistency under different viewing angles can be seen on the website of Japan Display Inc.
-Unlike TN LCDs, IPS panels do not lighten or show tailing when touched. This is important for touch-screen devices, such as smartphones and tablets.
-IPS panels offer clear images and stable response time.
