What's the difference between an ordinary display and a interactive board?

With the increasingly mature display technology and touch technology, LCD screen from the ordinary display to the display with touch function, and then to the Windows+ Android dual system touch teaching machine, bringing great convenience to the teaching. In the past, the electronic equipment used by teachers was projected to the projector through the computer, and then displayed on the screen, but now teaching education does not need so much auxiliary equipment, only need teaching machine equipment, so what are the differences between the ordinary display and teaching machine?

What are the differences between ordinary displays and teaching all-in-one machines?

1. Different functions.

The teaching all-in-one machine can have a built-in independent OPS machine, which can be detachable. The OPS machine can be installed. The screen can be operated like a computer.

In addition, the touch control machine can only input the computer signal, input signal is relatively single. Wireless screen projection is also available. Finger touch operation. Computer and touch - controlled computer two-way control. The touch-controlled integrated computer can also write intelligently. As a whiteboard, you can erase the contents with the back of your hand, which is more convenient and practical.

2. Different application fields.

The size of the touch-based teaching machine is 55 inches, 65 inches, 86 inches, and 98 inches, so the screen size is small. It is usually used in small meeting rooms, schools, and training institutions.

Splice screens are mainly used in meeting rooms, exhibition halls, video monitoring rooms and so on. It can be said that LCD splice screen is generally selected if the screen is more than 100 inches long.

3. Different screen sizes.

The size of the touch teaching machine is 55 to 98 inches, which is just a single screen. If you need a larger size, you can arrange multiple screens together, and then connect the screens so that the multiple screens show the same or different content, but the gap is larger in this way.

The size of the splice screen ranges from 46 to 65 inches, and the size of the splice screen can be either vertical or horizontal. For example, the size of the 6-by-4 46-inch splice screen is 1104. The screen size is generally designed according to the viewing distance, installation space and use environment of the user.

4.The display effect is different.

The advantage of teaching Touch all-in-one is seamless display of 2K resolution and 4K HD resolution. But the premise is that the input signal source is 4K, and the screen displays 4K effect. If the screen resolution is 4K, but the input signal source is 2K, the display effect is 2K. Therefore, the display effect of touch all-in-one machine and input signal source is the same, the display resolution is the same.

The LCD splicing screen has higher brightness, better white balance and richer color. But it will affect the overall beauty because there is a splice gap between the screen and the screen.

5. Different categories.

Like the traditional PC, the touch-based teaching all-in-one computer is composed of electronic components such as touch-based display, motherboard, memory, hard disk and video card.

LCD splicing screen can be divided into curved splicing screen, LCD splicing screen, plasma splicing screen, DLP splicing screen, transparent screen and so on. If the signal source of the computer is input into the splicing screen, it is necessary to splice the processor, the central control HDMI matrix, HDMI splitter, HDMI splitter and other auxiliary materials.
