Industrial touch screen selection skills

Become a man-machine interface touch screen is the industry, is a new kind of computer input device. The general industry according to the material generally divided into resistive touch screen, the capacitance induction, infrared and surface acoustic wave. Resistive touch screens use pressure sensor for control. Thin screen, touch any object can be displayed, but easy to be scratched. Capacitance induction type touch screen using the working current of the human body induction. High resolution, light transmittance can meet the requirements of the various aspects, such as the insulation medium could not work. Infrared touch screen using the infrared ray to detect and locate the on and off. User selects the pervious to light performance good baffle, and antireflection processing, can get very good visual effect. Is limited by infrared transmitting tube size, however, is unlikely to high density of ir, so this kind of touch screen resolution is not high. Surface acoustic wave touch screen is a kind of ultrasonic, the medium ( For example, rigid material such as glass or metal) The spread of the surface and shallow mechanical energy wave. Technology is stable, and surface acoustic wave touch screen controller by measure the position of the damping moment on the timeline to calculate the touch location, so its precision is very high. But the demand is higher, its work environment in the air dust cover on the reflection stripe around the touch screen or transducer, will influence the correct positioning of the system. Of beauty of science and technology has the following Suggestions and methods for small and medium enterprises choose touch screen 1, if you are using a capacitive touch screen, so it is recommended that you use for the first time, first to correctly installed according to the requirements of specification required for capacitive touch screen driver, and then, in turn, click on 'start' on the screen with your fingers 'program'/' Microtouch Touchware 'to run the screen calibration procedures, calibration is complete, the system will automatically after the calibration data stored in the register of the controller, then reboot the system after it without calibration screen again. 2, when using resistive touch screen, if it is found that the cursor up or only move in the local area, you can check to see if the touch area of the touch screen by other touch down, for example, once the touch screen was pinned under a display shells or cabinet housing, have been touched is equivalent to a certain point, then feedback to the controller the coordinates of the location is not accurate, the cursor is, of course, also can't correct positioning. If is the cabinet casing pressure touch area you can up the cabinet and the distance between the display screen, if is the display case pressure touch area, you can try to try display case screws loosen a bit. 3, in order to guarantee the normal work of the touch screen system, in addition to ensure the correctness of the system software installed, you must also remember do not install in a host of two or two or more of the touch screen driver, it will easily lead to conflict when a system is running, so that the touch screen system can't normal use. 4, if midway capacitive touch screen operation, again changed the touch screen resolution or display mode, or to adjust the touch screen after the refresh rate of the controller, feel the cursor and does not correspond to the touch point, must be on the touch screen system for calibration operation again. 5, changing the display resolution once system, adjust the screen size and installation for the first time have appear no or drift, click to start the application in the positioning of the program, but everybody when positioning, best to use more fine pen or fingertip to locate, it is correct. 6, if use your hands to touch or other touching surface acoustic wave touch screen, touch screen is very slow, it shows that most likely touch screen system is obsolete, the internal clock frequency is too low, or is due to the touch screen surface is water in the mobile, restore fast response to touch screen, must replace or upgrade system, or use dishcloth dry the water on the surface of the touch screen. 7, don't let the touch screen surface of water droplets or other soft glue on the surface, otherwise the touch screen is easy to mistake that has caused surface acoustic wave touch screen is not allowed. To clear the dirt on the touch screen surface, you can use a soft dry cloth or cleaner carefully wipe from the center outwards, or with a dry soft cloth dips in industrial alcohol or glass cleaning fluid cleaning touch screen surface.
