This will depend on how you choose to use the screen. Generally Infrared is cheaper, so if the screen is upright on a wall or stand, then this technology is perfect. The extra benefit of infrared is that you don’t need to touch the screen with a finger to make a touch point. The beams that go across the glass surface can be broken with anything. So you can use a pen, gloved hand, or anything. (this is why cuffs and ties can cause a touch point if the screen is flat- see below). PCAP is better for tables or where the screen is flat or at an angle. Because it doesn’t have a frame, PCAP is much better aesthetically. It also requires an actual finger or special stylus to create a touch point so things like ties or cuffs don’t create “ghost touch points” like an Infra Red frame would. If you need a video wall that will be viewed from a distance greater than 2 meters then we would generally recommend a LED video wall. We can make these interative using gesture based technology. LED Video Wall technology is also very good for outdoor use as it is very bright and has a high contrast. We can supply waterproof outdoor LED Video wall solutions. Our LED video wall range can be viewed here We offer both LED and LCD video walls for purchase and renting. (Indoor only).
