Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices lack the ability to be freely folded or unfolded while maintaining reduced power consumption, limiting their versatility and efficiency.
Innovation Solution
A display device with multiple folding portions that allow for various folding configurations, including the use of rack gears, pinion gears, and elastic members, enabling flexible folding and unfolding while minimizing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display area is reduced to a quarter of the unfolded state, then power consumption is reduced, but the display area and visibility are reduced
Solution Approach 1:
The display device employs multiple folding portions that enable the display panel to dynamically change its configuration between unfolded and folded states. This dynamic structure allows the display area to be adjusted from full size to a quarter size, thereby reducing power consumption when the device is not in full use while maintaining the ability to expand to full display area when needed.
Solution Approach 2:
The display panel is divided into multiple folding portions (first, second, third, fourth, fifth, and sixth folding portions) that segment the display area into different regions. This segmentation enables selective folding of specific portions while keeping others active, allowing the display to maintain partial functionality with reduced power consumption while preserving access to the complete display area when unfolded.
2Adaptability or versatility
If multiple folding portions are added to enable flexible folding configurations, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The display device is segmented into multiple folding portions (first through sixth folding portions) distributed across the display panel. Each folding portion can be independently folded or unfolded, providing versatile folding configurations. This segmentation allows the device to achieve high adaptability while maintaining a modular structure that manages complexity through repetition of similar folding units.
Solution Approach 2:
The multiple folding portions serve universal functions of enabling various folding configurations (e.g., folding in different directions, creating different display orientations). Each folding portion can be folded in multiple directions (first direction or second direction perpendicular to the first), providing multi-functionality that increases adaptability without requiring entirely different structural solutions for each folding scenario.

AI summary
A display device includes a display panel which includes a display area which displays an image on a first major surface of the display panel. The display panel includes a first folding portion, a second folding portion, and a third folding portion which are disposed in the display area, and an extension direction of the first folding portion, an extension direction of the second folding portion, and an extension direction of the third folding portion are different from each other.
