What are the advantages of nano-blackboard teaching all-in-one machine capacitor touch G-G?

Multimedia capacitive dual-system interactive touch screen all-in-one technology is the use of human current sensing to carry out the work. Capacitive touch all-in-one machine is a four-layer composite glass screen, the inner surface of the glass screen and the mezzanine each coated with a layer of ITO, the outermost layer is a thin layer of clay glass protection layer, mezzanine ITO coating as a working surface, four corners lead to four electrodes, the inner ITO for the shield to ensure a good working environment. When the finger touches on the metal layer, the user and the touch screen surface form a coupling capacitor due to the human body electric field, which is a direct conductor for high-frequency currents, and the finger sucks a small current from the contact point. This current flows from the electrodes at the four corners of the touch screen, and the current flowing through the four electrodes is proportional to the distance from the finger to the four corners, and the controller calculates the position of the touch point by accurately calculating the ratio of the four currents.

             In order to break the traditional touch principle infrared touch all-in-one machine dual-system interactive multimedia teaching all-in-one machine electronic whiteboard educational conference flat-board education board of the new limitations, is the infrared shortcomings and advantages to play to the extreme, pure capacitive G-G double-layer clamping process. Appearance profile private mold appearance, internal modular design, in the daily use and maintenance more user-friendly, supporting OPS industrial control pc unit (commonly known as computer host and Android system: integrated CPU, memory, hard disk storage) and the perfect combination of hardware profile steel aluminum profile housing multimedia multi-functional capacitive pure flat education (CHISEN) multimedia teaching machine, the external only need a power cord to achieve touch operation of the machine.
