Which is better, traditional projection or intelligent projection, Zhihu?

The biggest difference between intelligent projector and traditional projector is that intelligent projector has an operating system, while traditional projector does not. Intelligent projector is like an all-in-one machine, with a computer host and screen, which can be used when it is turned on; The traditional projector without operating system is just a screen, which needs external operating systems such as set-top boxes and computers to project content.

With the projector of operating system, the function has gone up N steps! Turn on the computer and you can enter a screen similar to a smart TV. You can connect with wifi and Internet cable, download and use various apps at will, watch movies, karaoke, fitness yoga, and even have rich learning resources. In addition, smart projectors can also realize the same screen projection of mobile phones, Bluetooth connection, AI voice control, and some also have their own power supply. In terms of experience, ordinary projectors are far behind.

2, the difference between the projection light source

Generally speaking, most intelligent projectors on the market now adopt DLP projection technology and LED light source, which is also commonly known as LED projection. Traditional projectors mostly use 3LCD projection technology and use traditional bulb light source, which is called bulb machine.

The advantages of light bulb machine are higher brightness and better projection picture. However, the traditional projector uses high-pressure mercury lamp bulbs, which have a life span of only 2,000-4,000 hours due to serious fever, and need to be replaced regularly. Although the projection with LED light source is not as bright as the bulb machine, it has high gray level, more natural color, less calorific value and long service life, which can basically reach 20,000 hours.

3. Difference of lens parameters

The lenses of traditional projectors are mostly zoom lenses, while smart projectors are mostly fixed-focus lenses. Focusing and keystone correction methods are also different. Most traditional projectors need manual focusing and manual correction. Intelligent projector can focus and correct automatically; Moreover, in the way of projection, there are more ways of intelligent projectors.

4, the difference between the connection mode

The connection mode of intelligent projector has also been greatly improved. Traditional projectors are connected through various transmission lines. When using the traditional projector, it is necessary to connect external devices such as power supply, computer or set-top box, stereo, etc.

The intelligent projector can be used directly without connecting other devices. Because it is equipped with an operating system, you can watch movies, play games, karaoke and so on. As long as you are connected to the Internet, you can also wirelessly connect with your mobile phone to realize wireless screen projection.
