AI Technical Summary

Technical Problem

When existing lighting display devices increase touch function, they need to increase the number of electrode layers or plug-in touch screen panels, resulting in an increase in device thickness and an increase in production costs, making it difficult to achieve a lightweight design.

Method used

An illumination display screen is designed, including a transparent cover plate, a first metal layer, a second metal layer, a dielectric layer, an illumination display film layer and a packaging layer. By providing a dielectric layer between the first metal layer and the second metal layer, an electrode structure that is isolated from each other is formed, and the sharing of illumination display and touch control functions is realized.

Benefits of technology

Without increasing the thickness of the lighting display screen, the sharing of lighting display and touch functions is achieved, meeting the requirements of lightweight design, and reducing production costs.
