Research And Implement On High Reliable Resistive Touch Screens

Touch-screens have largely replaced keyboards and mouses as a kind of human-machine interactive interface. The operation of the host computer can be realized by touching the icons and texts on the touch-screen. Touch-screens have been widely accepted for its high efficiency and intuitiveness, and applied to industry,medical enterprise, communications as well as military equipment. Therefore,the designing of highly reliable touch-screens under particularly working environments has been one of the main researching direction. And resistive touch-screens has been the common choice for being cheap and robust. However, limited by crafts and materials, they also have defects like positioning drifting and misuse after long working hours in high temperature and humidity.To solve the problem, this thesis aims to develop high-reliable resistive touch-screens applied to particular environments. Both software and hardware designing have been given out after studying the principles of touch-screens. The products are all testified by environment experiments, namely, high temperature experiments,high humidity experiments,severe temperature change experiments,vibration experiments.Accordingly,the products features in the following aspects:①wide operating temperature range②good vibration resistance③high resolution④high reliability⑤multitouch supportingIt is valuable in industry. After the designing and verifying, the products achieves the controlling aim through touches on the screen, replacing mouses and keyboards as the human-machine mediation.
