touch screen lcd cheap.The main advantages of a touch screen are improved human-computer interaction capabilities , increased input device interfaces, and the disadvantage is high cost. The cost of a touch input device is higher than that of a keyboard, mouse, trackball, and other input devices. Environmental restrictions may also bring some disadvantages. However, the environment may be extremely harsh: cold enough to require users to wear gloves-this may make the capacitive touch screen useless, or too dirty, too much dust will weaken the optical tomb foundation technology. Of course, these situations will also seriously affect the design of standard interfaces. For all applications, no touch screen technology is the best. For example, resolution and response time also vary with different technologies. If the environment is harsh, the selected touch screen should be resistant to pollution, abrasion and abrasion. Screens may need to be sealed in extreme environments. However , not all touch screens are compatible with gasket seals.
