Can LED be touch screen?
Turn an LED or LCD TV Screen into a touchscreen Another option for either LED or LCD TV screens to become touchscreens is to use a glass interactive touch screen overlay.
What is interactive projector?
Interactive projectors are generally ultra-short throw projectors with projection mapping. The images and words are projected onto a projector screen or whiteboard, much like your standard projectors. Unlike most projectors, however, interactive projection gives you the ability to interact with what you’re projecting.
What color projector screen is best?
The gray screen absorbs ambient light that strikes it better than a white screen does. In so doing the black level on the screen is maintained. This works because, assuming the projector has ample lumen output as most digital projectors do, whites remain satisfyingly white while blacks are maintained at a deeper black.
