AI Technical Summary

Technical Problem

The existing flexible electronic paper segment code display module's hot melt film + PET + FPL + hot melt film structure has poor waterproof effect, causing water to enter the electronic paper, affecting the product's reliability and softness.

Method used

A combination of a PS protective layer and flexible edge-sealing adhesive is used, combined with a barrier layer of aluminum oxide or silicon oxide material to form an electronic paper segment code display module with good waterproof performance. The internal circuit is electrically connected through silver glue, and flexible edge-sealing adhesive is applied to the gaps to prevent water vapor from entering.

Benefits of technology

The electronic paper segment code display module is realized to be both flexible and waterproof, which improves the reliability and softness of the product while simplifying the production process.

Abstract

The invention discloses an electronic paper segment code display module and a production method. The electronic paper segment code display module comprises a PET layer, an FPL electronic paper layer, a PS protection layer and flexible edge sealing glue. The FPL electronic paper layer and the PET layer are electrically communicated with an internal circuit through elargol; the FPL electronic paper layer is arranged on the PET layer; the PS protective layer is arranged on the FPL electronic paper layer; the flexible edge sealing adhesive surrounds a gap between the FPL electronic paper layer and the PS protection layer to prevent water vapor from entering the FPL electronic paper layer; and the FPL electronic paper layer comprises a segment code display part. Comprising the following steps: A10, dispensing silver colloid on circuit connection points on an FPL electronic paper layer; a20, the FPL electronic paper layer is attached to the PET layer; a30, the PS protection layer is attached to the FPL electronic paper layer; a40, flexible edge sealing glue is smeared in the gap between the FPL electronic paper layer and the PS protection layer; and A50, curing the flexible edge sealing glue.
