Abstract

This publication describes improved foldable display structures with electrostatic discharge (ESD) mitigation structures that enable more robust foldable devices with improved longevity and increased electrical protection. In aspects, a foldable device includes a foldable display structure that includes at least a decorative trim layer, a pad‑print layer, an adhesive layer, a chip‑on‑plastic (COP) layer, and a display panel layer. The foldable display structure can be housed within a metal enclosure. The decorative trim layer may be configured as a border structure and is positioned to secure edges of the pad‑print layer within the metal enclosure. The pad-print layer includes at least one ESD path configured to electrically connect the pad-print layer to the metal enclosure. The adhesive layer may be a low‑temperature‑curing conductive adhesive configured to electrically connect the decorative trim layer and the pad‑print layer to the metal enclosure. The COP layer includes various display driver components configured to direct pixels of the display panel to emit various colors and intensities at a refresh rate. Together, the at least one ESD discharge path and the low‑temperature‑curing conductive adhesive direct electric charge that can accumulate on the pad-print layer to the metal enclosure. Thus, the various display driver components of the COP layer are protected from the electric charge, enabling a more robust foldable device with improved longevity and increased electrical protection.
