Foldable Display Layout for Drop-Resistant Screen Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable dual-screen display apparatuses face challenges in enhancing display size while maintaining portability and protecting against damage, particularly from accidental drops.
Innovation Solution
A display apparatus with multiple rotatable constituent parts arranged such that one part protrudes and another part recesses during folding, redirecting impact forces to more robust components, thereby reducing screen damage and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display apparatus uses multiple screens to enlarge display size, then the display area is increased, but the device becomes more prone to damage from accidental drops
Solution Approach 1:
The display apparatus is divided into multiple constituent parts (first, second, and third constituent parts) that can be folded relative to each other. This segmentation allows the device to achieve a larger display area when unfolded while maintaining a compact form factor when folded, and the distributed structure helps dissipate impact forces during drops
Solution Approach 2:
The constituent parts are arranged in a nested configuration where the second constituent part is positioned between the first and third constituent parts. When folded, these parts nest together in a compact arrangement that protects the screens, and the nested structure provides multiple layers of protection against impact forces
2Volume of moving object
If the display apparatus is folded to improve portability, then the device size is reduced, but the screens become more vulnerable to impact forces
Solution Approach 1:
The patent positions the second constituent part (containing screens prone to breakage) in a recessed location relative to the first and third constituent parts. When the device is dropped, the protruding first and third constituent parts act as sacrificial elements that absorb impact forces, converting the potential harm to the screens into a protective mechanism where the outer parts take the damage instead
Solution Approach 2:
The structural arrangement预先 positions the first and third constituent parts to protrude beyond the second constituent part, creating a protective configuration before any drop occurs. This beforehand arrangement ensures that impact forces will naturally contact the more robust first and third parts first, cushioning the screens in the second part from direct impact

AI summary
Embodiments of this application provide a display apparatus and an electronic device, and relate to the field of display device technologies. The display apparatus includes a first constituent part, a second constituent part, a third constituent part, a first connection part, and a second connection part. The first constituent part and the second constituent part move toward each other via the first connection part, and the second constituent part and the third constituent part move away from each other via the second connection part, so that the display apparatus is in a folded state. In the folded state, an orthographic projection of a boundary that is of the first constituent part and that is away from the first connection part onto a reference plane is farther from an orthographic projection of the first connection part onto the reference plane than an orthographic projection of a boundary that is of the second connection part and that is away from the first connection part onto the reference plane. An orthographic projection of a boundary that is of the third constituent part and that is away from the second connection part onto the reference plane is closer to an orthographic projection of the second connection part onto the reference plane than an orthographic projection of a boundary that is of the first connection part and that is away from the second connection part onto the reference plane. The display apparatus provided in embodiments of this application has good drop-resistant and screen breakage-resistant performance in the folded state, thereby effectively improving reliability of the display apparatus and prolonging a service life of the display apparatus.
