    Difference between IPS and PLS screen technologies?


    Are you curious to learn the difference between IPS and PLS screen display technolgies, especially with regard to viewing angles and resolution? Do you want to know which technology is better and how? Follow this thread and read answers by experts to know differences between IPS and PLS technologies.

    IPS technology stands for In-Plane switching and PLS marks to Super Plane-to-Line switching. Nowadays, both of these technologies are being used in making computing device screens. But it is said that the new PLS technology is the substitute of IPS screen. Please specify the basic difference between these two display technologies - in respect to their viewing angles and resolution. Also please specify - how the PLS technology is better than IPS?

    IPS (In Plane Switching) was introduced for touch monitors to take over twisted nematic monitors ( TN ) by Hitachi. IPS screen features include
    Crystal clear and enhanced color spectrum and resolution
    Better viewing angles. Though IPS have been quite popular later Samsung introduced PLS ( Plane to Line switching ) monitors. These are brighter with same high viewing angles. It is touch resistant. The IPS and PLS monitors cant be differentiated without much examination but they are superior over the TN monitors

    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 better viewing angles and better resistance to touching. Hitachi went on making improvements in this technology making the IPS displays quite popular among the users.

    In 2010, Samsung emerged as Hitachi's main competitor by introducing yet another new technology called PLS (Plane-to-Line Switching). The intention of Samsung was quite clear. It wanted to supersede and overtake the conventional IPS technology introduced by Hitachi in the mid nineties. PLS technology introduced by Samsung became the company's wide-viewing angle technology. Samsung has claimed that the PLS technology has further improved the viewing angle. It claims to have increased 10 percent increase in brightness. The company also boasts of 15 per cent decrease in the production costs. There is increase in image quality and in the flexibility of the panel.

    Both the IPS and PLS technologies are almost similar, and it is very difficult for the common user to know as to which technology has been used in the display screens. However, the PLS screens are known to be brighter and have better viewing angles. The PLS panels do not change colour on touching them. They do not leave a trail when the user drags his or her finger across the panel. The difference in both the panels is more of a technical and practical value. They are very small and mostly insignificant in the real life situations.
