Rollable Display Thin-Metal Cover for Smaller Rollers

The module cover is constructed from a thin metal plate (titanium or titanium alloy) that combines low density with high strength characteristics. The metal material inherently possesses high strength-to-weight ratio, allowing the cover to maintain structural integrity and impact protection capability while achieving reduced thickness and weight for aesthetic appeal.

The module cover made from thin metal plate provides rigid support to the display panel, enabling the system to use a smaller roller diameter. The high strength-to-weight ratio of the metal cover compensates for the reduced roller size, maintaining adequate support and protection capability during rolling operations while achieving a slimmer device profile.

The module cover is designed with integrated bezel portions that extend beyond the display panel edges. These bezel portions are formed as continuous extensions of the thin metal plate cover itself, providing edge protection without requiring separate protective components. The segmentation principle is applied in the sense that the cover is functionally divided into a main protective area and extended bezel areas, all within a single thin-layer structure.

The invention specifies using titanium or titanium alloy materials with controlled thickness parameters (indicated as a specific thin gauge). By carefully selecting and controlling the thickness parameter of the metal plate, the design achieves optimal balance between weight reduction and manufacturing feasibility. The parameter change principle is applied to optimize the thickness value to be thin enough for weight reduction but thick enough to maintain manufacturing precision and structural integrity.
