Basic Performance Judgment of Touch Screen

Abstract

Abstract With the development of science and technology, intelligent devices are entering every corner of our life. As an intelligent terminal, the touch screen carries most of the functions of human-computer interaction, and the performance of touch screen is particularly important. Through the comparative analysis of the principles of several types of touch screens and combined with the production practice of the original electronic whiteboard touch screen, this paper summarizes several aspects of the performance of the touch screen, such as anti-interference ability, signal strength, positioning accuracy and line drawing quality. Taking the electromagnetic induction touch screen as an example, this paper analyzes the generation and classification of touch screen defects, and summarizes some defect judgment methods of touch screen, which provides ideas for the selection of touch screen and the improvement of the overall quality of touch screen.
