Continuously improving optical characteristics, durability, and reliability in accordance with customer requirements have become factors that cannot be ignored by touch screen manufacturers. Here, we will briefly introduce several different types of touch screens. Touch screens can be divided into resistive, capacitive, infrared, surface acoustic wave, vector pressure sensing, and electromagnetic induction. In terms of the universality of market applications, the first four applications are mostly, and the resistive touch screen accounts for most of the first four. Each of the first four types of touch screens has advantages and disadvantages, mainly depending on its specific use. However, various types of touch screens are generally must have the following four conditions, namely: ?? good light transmittance, visibility provided; ?? long life cycle durability; ?? size consistent with the overall design of the user (comprising connection means), ?? Can match the cost required by the user. Regarding ?? , it should be said that the visibility is the best when there is no thin film over the glass substrate. The surface acoustic wave touch screen uses only one glass substrate, so its light transmittance can be more than 90%. In addition, it can use thicker glass materials and has strong resistance to performance. It is generally used in outdoor query information query systems and services. The system (mainly large size) will choose this type of touch screen. Regarding ?? , durability is difficult to judge. In public systems such as KIOSK, which is input by an unspecified number of people , consideration is given to the adverse conditions such as being touched by cigarette butts, being scratched by metal, etc., and being vulnerable to dust and grease In the environment, it can be said that it is best to use a capacitive type.
