Digital Display Surface 3D Relief Patterns

The patent applies dimensionality change by transitioning from a flat 2D display surface to a 3D surface with patterns of varying thickness. The patterns create relief structures that add vertical dimensionality, giving the display surface a three-dimensional appearance that enhances originality and distinguishes the device from conventional flat displays.

The patent implements local quality by creating patterns with different thicknesses at specific locations on the display surface. Instead of uniform treatment, the surface has localized variations in pattern height, where certain areas have greater thickness than others, creating visual interest and depth while maintaining manufacturing feasibility through selective application.

The patent applies preliminary action by preparing a mold with patterns of different thicknesses before the actual manufacturing process. The mold is pre-formed with the desired 3D pattern structures, and this prepared mold is then used to create the patterns on the display surface, simplifying the overall manufacturing process while achieving the complex 3D effect.

The patent uses copying by creating a mold that replicates the desired 3D patterns. The mold contains copies of the pattern structures with varying thicknesses, and through molding or casting processes, these patterns are transferred to the display surface, enabling reproduction of complex geometries without directly fabricating each pattern individually.
