The editor believes that the difference between electronic whiteboards and high brightness LCD advertising machines is that electronic whiteboards cannot emit light on their own, and projectors are needed to project computer images onto the electronic whiteboard, forming a trinity of operating environment for electronic whiteboards, computer hosts, and projectors; LCD advertising machines can generally be divided into two types:
One is to have a built-in computer host inside, and the other is to use only an LCD advertising machine as a flasher, with the computer host placed outside the LCD screen.
There is essentially no difference between the two, but their scientific names are interactive LCD touch screen all-in-one machine and interactive LCD writing touch screen flasher. The difference with electronic whiteboards is that LCD flashers can flash images, eliminating the need for projectors.
Difference 2: Electronic whiteboards have many interactive sensing skills, including electromagnetic, infrared, pressure sensing, ultrasonic, optical, etc., while LCD advertising machines generally have more infrared and optical types.
Difference three: The projection surface of an electronic whiteboard can be large, such as over 80 inches, but if the LCD advertising machine reaches a flashing screen over 80 inches, the cost will be much higher.
