A flexible film packaging structure with adjustable viewing angle

Abstract

The present invention discloses a flexible film packaging structure with adjustable viewing angle, which is surrounded by a cavity formed by a flexible substrate at the bottom, a light-proof composite film layer at the side, a light-proof film layer that can be electrically expanded, and a light-proof composite film layer at the top, wherein the light-proof film layer that can be electrically expanded is arranged on the outside of the light-proof composite film layer. The present invention can ensure the isolation of the device from water and oxygen in the air by using a multi-layer film with alternating interlayer arrangements; different light transmittances of the top and side surfaces are ensured by using different materials for the side and top surfaces; and the material that can be electrically expanded is used as the side packaging material, so that the display viewing angle range of the device in the cavity can be adjusted electrically.
