Naked 3D means that the mobile phone itself will process the 3D source, so that you can directly see the 3D effect without anything else. For example, you need 3D glasses to go to the cinema, but naked 3D can see the same 3D effect without 3D glasses. In this case, you can directly put the downloaded 3D movie into your mobile phone, or watch the 3D movie directly online.

However, it doesn't make any sense to watch 3D on a mobile phone. If the screen is too small to feel anything, the mobile phone will consume more power. Therefore, the naked-eye 3D of the mobile phone is still a very trivial function at present.
