Anti-Reflection Structures and Touch Electrode Integration

The circular polarizer is divided into multiple separate anti-reflection structures that are distributed across the display substrate. Each anti-reflection structure is positioned over specific sub-pixels rather than using a single continuous thick polarizer layer, thereby segmenting the anti-reflection function into discrete locations that collectively cover the display area while reducing overall thickness.

Anti-reflection structures are selectively positioned over specific sub-pixels based on their optical characteristics and viewing angle requirements. Not all sub-pixels require identical anti-reflection treatment, so the local quality principle allows optimization of anti-reflection performance where needed while maintaining flexibility in other areas, reducing the need for uniform thick coverage across the entire display.

The anti-reflection structures and touch electrode are merged into a single integrated assembly that is formed directly on the display substrate. The touch electrode is positioned between the anti-reflection structures, combining multiple functions (anti-reflection, touch sensing, and display) into one compact structure, thereby eliminating the need for separate thick adhesive layers to attach multiple components.

The integrated structure serves multiple functions simultaneously: the anti-reflection structures provide optical performance, the touch electrode provides touch sensing capability, and the combined assembly maintains flexibility for folding applications. This multi-functional design eliminates the need for separate dedicated layers for each function, reducing overall thickness while maintaining adaptability.

Transparent insulating layers are introduced as intermediary elements between the anti-reflection metal layers and the touch electrode. These insulating layers electrically isolate the conductive anti-reflection structures from the touch electrode, preventing signal interference while maintaining close physical proximity for thickness reduction. The intermediary layers allow the two functional components to coexist in close proximity without electrical coupling.

The spacing and positioning of anti-reflection structures relative to the touch electrode are locally optimized for each region of the display. By carefully controlling the distance and arrangement in different areas, the design achieves minimal separation where possible to reduce thickness while maintaining sufficient isolation to prevent signal interference, with the specific configuration varying based on local requirements.
