Display Device Ribbed Rear Case Weight Reduction

The patent removes the metallic top cover from the display device structure, extracting only the essential support function and implementing it through alternative means (rear case with ribs) made of lighter materials, thereby eliminating unnecessary weight while maintaining structural integrity

The patent changes the material parameter from metallic to non-metallic materials for the cover components, and changes the structural parameter by introducing ribs with specific thickness ranges (0.5-2mm) to achieve the required mechanical strength without using heavy metals

The patent extracts the metallic top cover component entirely and replaces it with a rear case structure made of plastic or other non-metallic materials, which are generally less expensive and easier to manufacture through injection molding or similar processes

The patent changes the material parameter from metallic to non-metallic materials, and optimizes the rib thickness parameter (0.5-2mm) to achieve adequate structural support at minimal material cost, reducing overall production expenses

The patent segments the rear case structure by adding ribs that divide the internal space, creating multiple support zones that collectively enhance coupling force while maintaining a relatively simple overall structure that can be manufactured as a single piece

The ribs in the rear case serve multiple functions: they provide structural support to enhance coupling force, define mounting positions for components, and maintain spacing between components, thereby reducing the need for additional separate support structures
