AI Technical Summary

Technical Problem

Existing polarizers are prone to failure in high temperature and high humidity environments. Moisture and NH4+ ions penetrate the polarizer, causing an iodine ion redox reaction that affects display performance.

Method used

A functional layer protection structure is set at the edge of the functional layer of the polarizer. A closed structure is formed by the extension of the base layer and the protective layer. Combined with the fixing layer and the compensation layer, the edge of the functional layer is covered to prevent water vapor and ions from penetrating.

Benefits of technology

It effectively prevents corrosion of the sidewalls of the polarizer's functional layer, improves the stability of the polarizer and the lifespan of the display module, and ensures stable display performance.

Abstract

The application provides a display module and a polarizing sheet. The display module comprises a display panel and a polarizing sheet. The polarizing sheet is located at least partially on the light-out side of the display panel. The polarizing sheet comprises a first side close to the display panel and a second side away from the display panel. The edge of the polarizing sheet is bent to the first side or the second side. The polarizing sheet comprises a protective layer, a functional layer and a substrate layer, and the functional layer is recessed from the protective layer and the substrate layer and is coated. The application improves the stability of the polarizing sheet by bending the edge area of the polarizing sheet and changing the structure of the edge area of the polarizing sheet.
