St. Louis-based TapTL LLC has created a line of interactive, transparent displays that function using a touch interface. These semicustom screens are designed to support Windows, OS X, Android and Linux platforms. They can accommodate signal input from a long menu of options that include Bluetooth, DisplayPort, HDMI, USB and Wi-Fi, giving users a huge amount of operational flexibility. Taptl's new screens offer NEMA 6/IP65 environmental protection ratings, and they're available in sizes ranging from a modest 15.6 inches to a luxurious 110 inches (prices range from $3,999 to $99,999). All taptl screens offer 1080p/4K resolution, and they can be used as a traditional stand-alone entertainment screen, as part of a networked navigation system, or — perhaps coolest of all — as part of a yacht's nonstructural window installations.
