Projectors are more commonly used in workplaces. When a meeting is required, it is often necessary to use a projector to display images, text, etc. on a large screen so that more people can see them. However, most of the projectors we have seen so far are relatively large and expensive, and not easy to carry around. If you need to go on a business trip and conduct a small meeting in another place where a projector is needed, it would definitely be very inconvenient. In this case, a portable projector can come in handy. It is only the size of a palm, and its appearance looks like a mobile phone, which can be held directly in your hand. Its lens can move up and down, allowing the display screen to be fixed at an ideal angle. One advantage is that its symmetrical shape makes it equally convenient for both left-handed and right-handed users. Its functions can be controlled via a touch screen.
