Flat panel display technology has evolved and gotten so good over the years from every one of the major manufacturers that it has become very difficult to differentiate between brands, as displays have become commoditized. With bezels getting smaller and smaller, even on standalone displays we are now even seeing some models that don’t include the manufacturer’s logo. So how do we choose which display to use? Well, in our business every application is unique and we do our best to find the best product to fit a particular job or requirement.
While I think it has gone somewhat unnoticed, LG is one of the few manufacturers that has a truly differentiating technology when it comes to displays used for digital signage applications. In-plane switching (IPS) is a technology that was developed in the late 1980’s that LG has adapted and continued to improve on, and provides some distinct advantages over other LCD displays, especially when used for signage.
In most cases viewers will be looking at digital signage displays as they are walking through a retail store, or traveling through an airport for example, and will be viewing off axis from a wide viewing angle. With non-IPS panels, as the viewer moves off access they will notice changes in color, dimming, and reduced contrast, as opposed to IPS which offers a true wide 178 degree viewing angle with no degradation in picture quality.
Additionally, IPS displays have built-in temperature control that adjusts to light and heat eliminating dark or blackened areas that can occur with traditional LCD displays in high ambient light conditions, while increased physical stability of the panel minimizes image distortion when external pressure is applied, from a human touch for example.
LG includes IPS technology in their entire line up of commercial televisions, monitors, and video wall displays and should be at the top of your list when considering displays for your next digital signage project.
