IPS ((In-Plane Switching technology): was originally developed by Hitachi and had been in use from the mind nineties. Earlier to this twisted nematic (TN) technology was used to make panels for monitors. Hitachi introduced the IPS technology for liquid crystal display (LCD) panels. This technology was used to overcome limitations faced by TN matrices, which included slow response, small viewing angles and low quality colour reproduction. The new technology of In-Plane Switching (IPS) introduced arrangement and switching of the molecules of the liquid crystal (LC) layer between the glass substrates in a plane parallel to these glass plates. This technology made a lot improvement in the colours schemes and the resolution in the technology used in twisted nematic (TN) monitors. It provided a...
