Touch-screen machines, Yingtan touch screen, Hing Tai-chi Electrical and Mechanical touch screen repair

The medium works touchscreen and transmission of information, the touch screen is divided into four types, they were resistive, capacitive sensing, infrared and surface acoustic wave type. Each category has its own touch screen advantages and disadvantages Panasonic touch screen, to understand what kind of touch screen suitable for the occasion, the key lies in each class to know the touch screen technology works and features. Next, the above-mentioned various types of touch screen briefly describe: resistive touch screen This touch screen is controlled by the pressure sensor. The main part of the resistive touch screen is a display surface with a very thin film with resistive screen, which is a multi-layer composite film plc touch screen, it is a layer of glass or hard plastic plate as a base, the surface is coated with a layer of transparent metal oxide (transparent The conductive resistance) conductive layer, above the surface and then covered with an outer layer of hardened, smooth anti-friction plastic layer, and its inner surface is also coated with a layer of coating, among them many of the small (less than 1/1000 inch) transparent separation point two conductive layers separated by insulation. When a finger touches the screen, two conductive layers in the touch point position will have a contact resistance changes, a signal in the X and Y directions, and then send the touch screen controller. The controller detects the contact and the calculated (X, Y) position, then the operating mode of the mouse according to the simulation. This is the resistive touch screen technology the most basic principles. Resistive touch screens are available so hard object operation. The key resistance class touch screen that material science and technology, a transparent conductive coating material commonly used are: Highly reliable design enthusiast hardware design enthusiast mobile phone touch screen repair, the whole low-power, providing up to 36 months quality warranty; dual-CPU processing mode, an ARM chip for processing graphical man-machine interface and data logging ; single-chip CPU to ensure independent control and real-time sampling, to meet the stringent requirements of the industrial field; by 4KV group pulse immunity test. Rich data logging AI-3700 with data recording function, you can display real-time trend, beam and historical trends, and provide a report in the form of recorded data and alarm logging. Has 150M of storage space, assuming that only one control loop is set to one minute of recording time data, the stored data can be up to 12 years. Data stored on the instrument not only to the LCD screen for playback curve and values ??can be exported for further analysis and processing on a computer via U disk.
