Abstract: The so-called capacitive touch control, is a relative positioning system using a transparent screen.By covering the screen with a transparent film of a metal conductor, the touch position is calculated precisely calculated by current change when the user touches it.It supports multi-touch control, and because its working principle needs to sense human current, so it only responds to human operation, will not respond to other objects, and can effectively avoid accidental touch.
In recent years, due to the integration of business demonstration, collaborative office, video conference and many other functions, in line with the new needs of mobile, digital and intelligent business office, the market heat of the all-in-one conference machine continues to rise.In particular, with the continuous normalization of epidemic prevention and control, the demand growth prospect for all-in-one conference machines is promising.
Subsequently, more and more brands on the market to join the ranks, and users can choose more and more range of products.In terms of its touch technology, there are often many options.So, how exactly should users choose according to their own needs?
In terms of touch control technology alone, there are resistance, electromagnetic, capacitance, infrared and many other kinds, however, after the development and choice of the market, at present, capacitance and infrared are more common two types.
The so-called capacitor touch control is a relative positioning system using a transparent screen.By covering the screen with a transparent film of a metal conductor, the position of the touch is precisely calculated by the current change when the user touches it.It supports multi-touch control, and because its working principle needs to sense human current, so it only responds to human operation, will not respond to other objects, and can effectively avoid accidental touch.And the touch response is relatively faster and more accurate.Capacitive screen can usually be quite flat in appearance, and waterproof and dust-proof, not afraid of strong light interference.However, due to the greater technical difficulty, so the cost is relatively high, and it is relatively difficult to install, so the large-size applications above 55 inches are relatively few.
Infrared touch, on the other hand, is detected by setting an infrared matrix at the edge of the screen and forming an infrared detection network on the surface of the screen, which can respond to any object, including the human body.It is free from current, voltage, electrostatic interference.And the price is relatively low, easy installation, stability and service life are good, and even more than 100 inches of product applications.But the disadvantage is that there are grooves, affecting the appearance, and not dustproof and not waterproof, afraid of strong light interference.
See this, I believe you have a certain understanding of these two common touch technology, if you pursue large size, low cost, or explosion-proof special use needs, can consider infrared touch; if you pursue more accurate and fast touch experience, or do not want to be troubled by non-human misoperation, you can choose capacitive touch products.
