All in one pc match with software for various application
The touch all-in-one pc is a highly integrated electronic technology product, which integrates all the device functions of a traditional computer into one machine, occupies a small space, does not require troublesome wiring, and only needs a power cord. In addition, the overall design of the touch all-in-one pc gives the impression that it is very simple, elegant, exquisite and fashionable. And in the touch screen technology, has been walking in the forefront of the touch screen product industry. The sensing screen of the capacitive touch screen is a four-layer composite glass screen. The inner surface and the interlayer of the glass screen are each coated with a conductive layer, and the outermost layer is a thin layer of silica glass protective layer. When we touch the sensor screen with a finger, the electric field of the human body makes the finger and the touch screen surface form a coupling capacitance. For high-frequency current, the capacitance is a direct conductor, so the finger sucks a small current from the contact point. . This current flows out from the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the position of the touch point by accurately calculating the ratio of the four currents. .
Application of touch all-in-one pc:
1. Interactive touch query
The media touch all-in-one pc is produced to simplify people's operation of the computer, and its main function is to query information. Manufacturers can customize query software according to the requirements of different industries. Publishers can enter and publish relevant information.
