Dual Folding Area Display Device for Inward-Outward Form Factor Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable display devices face challenges in optimizing their form factor and display area exposure during different usage forms, lacking a seamless transition between inward and outward folding configurations that efficiently utilize screen space and protect the display.
Innovation Solution
A foldable display device design featuring first and second non-folding areas, with first and second folding areas that allow the non-folding areas to face each other or away from each other, utilizing different adhesive configurations and patterned plates to facilitate flexible folding and minimize wasted space, while ensuring the display area is fully or partially exposed as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device is configured to fold inwardly to protect the screen, then the display is protected during non-use, but the display area cannot be fully exposed when needed
Solution Approach 1:
The display device employs dynamic folding configurations that can transition between inward folding (for protection) and outward folding (for full display exposure). The folding areas are designed to be flexible and reconfigurable, allowing the device to adapt its form factor based on usage requirements. This dynamic capability resolves the contradiction by enabling the same structure to serve both protective and expositional functions at different times.
2Device complexity
If the display device uses a single folding configuration, then the structure is simple, but it cannot efficiently utilize screen space during different usage forms
Solution Approach 1:
The display device is segmented into multiple folding areas (first folding area and second folding area) with distinct folding axes and directions. This segmentation allows different portions of the display to be folded independently in different configurations, enabling efficient screen space utilization for various usage scenarios such as viewing angles, sharing content with multiple users, or protecting specific display regions while keeping others accessible.
3Ease of manufacture
If the folding areas are designed with uniform patterns, then the manufacturing is simpler, but the device cannot optimize form factor for different usage forms
Solution Approach 1:
Different folding areas are designed with locally optimized patterns suited to their specific functions. The first folding area may have patterns optimized for its folding axis and movement, while the second folding area has different patterns tailored to its folding characteristics. This local differentiation enables each folding area to achieve optimal form factor transformation for its intended usage scenario, rather than using a one-size-fits-all pattern approach.

AI summary
A display device includes a first plate, a second plate disposed on the first plate, and a display module disposed on the second plate. The display module includes a first non-folding area, a second non-folding area, a first folding area disposed between the first non-folding area and the second non-folding area, and a second folding area disposed between the first non-folding area and the second non-folding area. The first folding area is configured to fold so as to bring the first non-folding area and the second non-folding area to face one another in a first use form. The second folding area is configured to fold so as to bring the first non-folding area and the second non-folding area to face away one another in a second use form.
