Watch mobile movies in lewd hotels.

In the hotel, you can put it on TV to watch movies, but other rooms will not show the same picture.

Every room in the hotel is independent, and the output signals of the equipment are one-to-one, so there is no problem of equipment sharing. Therefore, even if the screen is projected to one room to watch a movie, other rooms will not display the same picture or received TV programs.

If you watch videos on TV by projecting a screen on your mobile phone, the mobile phone consumes too much power and gives off heat for a long time, which shortens the service life of the mobile phone.

Extended data:

When watching the projection, the light source is projected on the wall, and the projection screen is large and the brightness of the screen is relatively soft, so that people can stay away from the screen when watching, and their eyeballs can keep turning, and the direct stimulation of the light source to the eyes can be reduced, with little harm to the eyes.

At present, the light of different projectors on the market is diffused through the screen or white wall, and the light of the picture is omni-directional, which is very similar to the imaging mode in nature, so the picture will not be tired after a long time.

The light of ordinary TV is aimed at the eyes, but the projector needs to illuminate the developing surface, such as the wall or screen, before imaging, thus eliminating the direct light of human eyes.
