Staggered Support Member Patterns for Display Bending Stability

The support member is divided into multiple patterns (first pattern, second pattern, third pattern) with different depths. The first pattern has a first depth, the second pattern has a second depth greater than the first depth, and the third pattern has a third depth less than the first depth. This segmentation creates stress distribution zones that prevent stress concentration in the folding area while maintaining overall structural strength and durability.

Different regions of the support member are given different local qualities through varying pattern depths. The first pattern region has a first depth suitable for general support, the second pattern region has a greater second depth for enhanced stress distribution in critical areas, and the third pattern region has a lesser third depth for flexibility. This local quality variation optimizes stress distribution while maintaining manufacturability through a systematic multi-depth pattern design.

The support member incorporates curved folding lines that allow smooth bending without sharp angles. The multiple patterns with varying depths create a gradual transition zone along the folding line, enabling the support member to bend while maintaining structural integrity. This curvature approach allows reduced thickness for portability while preserving strength during bending operations.
