Curvature-Adjustable Display Structure With Constant Bezel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, particularly curved OLED displays, face challenges in accommodating multiple users' viewing angles and maintaining a consistent bezel size while allowing for curvature adjustments, which affects user immersion and heat dissipation.
Innovation Solution
A display device design featuring a modular structure with an inner sheet, cover bottom, and middle cabinets that allow for horizontal curvature changes, incorporating adhesive tapes and rib structures for flexibility and rigidity, along with a bending module for manual or motorized curvature adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is made curved to improve user immersion, then the sense of immersion is enhanced, but the viewing comfort for multiple users simultaneously deteriorates
Solution Approach 1:
The patent implements a curvature adjustment mechanism that allows the display panel to dynamically change between curved and flat states. The middle cabinet and cover bottom can be rotated relative to each other, enabling the display to adapt its curvature based on usage scenarios, thus providing immersion when needed while maintaining viewing comfort for multiple users
2Adaptability or versatility
If the curvature of the display device is changed, then the viewing angle and immersion are improved, but the bezel size consistency deteriorates
Solution Approach 1:
The patent divides the cabinet structure into separate segments (middle cabinet, cover bottom, side cabinets) that can move independently. The middle cabinet is rotatably connected to the cover bottom, allowing curvature adjustment while the side cabinets remain fixed to maintain consistent bezel dimensions at the display edges
3Adaptability or versatility
If the display device structure is made flexible to allow curvature changes, then the adaptability is improved, but the structural stability deteriorates
Solution Approach 1:
The patent employs a dynamic structure where the middle cabinet can rotate relative to the cover bottom through a defined axis, enabling curvature changes while maintaining structural integrity through precise mechanical connections and support ribs
Solution Approach 2:
The patent applies different structural properties to different parts of the device. The middle cabinet and cover bottom have flexible joints for curvature adjustment, while the side cabinets and bezel areas maintain rigid structures to ensure overall stability and precise bezel dimensions

AI summary
In a display device whose curvature changes in a horizontal direction, a middle cabinet includes each first middle cabinet positioned on each of a top surface and a bottom surface of a display module, and each second middle cabinet positioned on each of a left surface and a right surface of the display module, and the display module is fixed to the second middle cabinet, and an inner sheet and a cover bottom are coupled to the second middle cabinet to be able to slip in the horizontal direction, so that a constant size of a bezel may be secured without a change in a position of the display module.
