touch screen interactive whiteboard
Fusion in recent years, due to the business presentation, collaborative office, video conference, and many other functions, in line with the mobile, digital, intelligent business office of the new requirements, the heat rising all-in-one PC market. Especially with epidemic prevention and control of the normalized continues to advance, meeting the demand of the all-in-one growth prospects.
Second, is more and more brands touch screen interactive whiteboard on the market to join the ranks, users can choose the product scope is also more and more. In terms of its touch technique, often also have many choices. So, how to according to the needs of their users to choose? This article is to show you understand it.
Alone touch technology, there is resistance, capacitance, infrared, electromagnetic many kinds, however, after the development of the market and choice, the capacitance and the infrared is two types which are frequently used.
The so-called capacitive touch, is to use interactive whiteboard for schools transparent screen relative positioning system. By covering a layer of conductive metal objects on the screen of the transparent film, when the user touches the precise location of touch through the current changes. Its multi-touch support, and due to its principle of work need to induction current human body, therefore only has the response to the human body, with other objects don't response, can effectively avoid the mistake. And 4k smart board touch response relatively faster, more accurate. Capacitive screen is usually in appearance can be quite flat, waterproof and dustproof, afraid of light interference. But due to technical difficulty is bigger, so the غير مجاز مي باشدt is relatively high, some will be relatively complicated to install, so relatively few 55 inches above the large size of application.
And infrared touch, it is through setting somehow cross 75 inch smart board infrared matrix on the edge of the screen, the screen surface infrared detection network, to detect touch operation, which can be of any object, including the human body, make the operation response. It is not affected by current, voltage, electrostatic interference. And the price is relatively cheap, easy installation, stability and service life is pretty good, even more than 100 inches of product applications. But the disadvantage is that there are grooves, affect beautiful, waterproof and dustproof not, afraid of light interference.
See here, I believe you of the two kinds of common touch 75 smart board technology has had certain understanding, if you pursue the large size, low غير مجاز مي باشدt, or a special use requirements, such as explosion-proof consider infrared touch; If the pursuit of more accurate quick touch experience, or don't want to be the wrong operation problem of the human body, can choose a capacitive touch products.
