There is a lot of restrictions on non-screen TVs
1. No screen television has requirements for the projection area. “Generally needs to be flat and the background is whiteâ€.
2. No screen TV can project a maximum of 180-inch screen, but this is an effect that can be achieved at a distance of about 5 meters. For most ordinary families, it is necessary to have a space of five meters and a wall large enough. Are the conditions harsh?
The difference between non-screen TV and LCD TV
