Regardless of the type of touch screen, whether used in daily life or any work setting, proper usage and maintenance are essential.
Surface Acoustic Wave Touchscreen
Ideal for any indoor, unknown application scenarios. Particularly suitable for environments with high cleanliness and minimal dust. The surface acoustic wave touch screen's sensing medium is the finger (excluding nails, gloves can also be worn) and other softer materials that can perfectly match glass, such as rubber.
In daily use, it is recommended to keep the touch screen surface clean. Use a cleaning agent and a damp cloth to wipe the surface of the touch screen. If the reflective stripes of the touch screen are exposed, clean the stripes regularly with a brush. If the touch screen is installed within a monitor, frequently clean the dust at the contact point between the touch screen and the monitor's bezel with a brush. If there is a delay in touch response or inaccurate touch, insert a business card about 3 centimeters deep into the gap between the touch screen and the monitor's frame, gently press the touch screen, and move the card around the monitor's frame a few times (try to keep the card close to the touch screen). This will restore the touch screen's sensitivity.
Resistive Pressure Touch Screen
The drawback of the resistive touch screen is its vulnerability to scratching, making it suitable for fixed personnel operating known objects. The resistive touch screen requires only pressure to function, whether using a finger, pen, or other objects, but it should not be operated with sharp or pointed items.
In daily use, the primary concern is to prevent scratches. If you notice that the touch coordinates are consistently fixed at a single point, it might be that the display frame is pressing down on the touchscreen at that location. In this case, you should loosen some screws on the display to avoid the touchscreen being subjected to pressure (typically, this should be handled by a professional). If the touchscreen exterior is excessively dirty, you can clean it with a damp cloth.
Scratches on the outer layer of a five-line or six-line resistive touch screen are typically manageable and the screen can still be used normally; however, once the outer layer of a four-line resistive touch screen is scratched, it becomes difficult to use.
On the other hand, prolonged touching at a specific location on the touchscreen can lead to a significant decrease in transparency or the appearance of creases and bubbles on the surface. This issue can be resolved by modifying the touch software to move the touch buttons away from that location.
Capacitive Inductive Touch Screen
Not suitable for use in environments with electromagnetic interference or where precision is required. This touchscreen can only be operated by touching with the fingers (not nails) and the body.
In daily use, avoid striking the touch screen with hard objects, as this may cause a small hole at the impact point, rendering a large area around it unresponsive. If the touch screen's surface is excessively dirty, you may clean it with a damp cloth.
Capacitive touch screens often experience "drift" during use, resulting in inaccurate touch responses. It is advisable to regularly perform calibration and positioning procedures.
Infrared Sensing Touchscreen
Ideal for a variety of unexposed applications with unknown usage objects. The infrared touch screen's sensing medium is any item that can block light, such as fingers, pen shafts, small sticks, etc.
Infrared touch screens should be placed in environments free from infrared interference. If the infrared touch screen is unresponsive, clean the transparent parts around the screen thoroughly. If the surface of the touch screen is excessively dirty, a damp cloth can also be used for cleaning.
