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. Users only need to follow the prompts and touch the touch screen to query the information and services they want. It is fast and simple. Functions such as public information inquiry and self-service business processing have enhanced human-computer interaction.

2. Simple operation, safe and reliable

Although the application of computer is very popular now, not everyone can use the mouse and keyboard of traditional computer proficiently to operate. The application of the touch all-in-one pc perfectly solves this problem. Its operation does not require the use of a keyboard and a mouse. If you want to check something, you only need to touch it with your fingers to get the answer, which greatly facilitates the operation. Another point is that it makes the operation of the computer completely locked on the computer screen, without keyboard and mouse, safe and reliable, and will not affect the operation of the system because of the user's operation.
