Foldable Display Device with Segmented Sections for Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses with multiple display sections face challenges in reducing size while improving viewability and minimizing power consumption, as they often require increased power due to larger display areas and limited angle adjustments.
Innovation Solution
The electronic apparatus features a display device with multiple sections that can independently display images, where the angles between adjacent sections are variable, allowing for different states such as unfolded, intermediate, and folded configurations, with the control unit managing image display on specific sections to optimize viewability and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large display screen is used to increase display area, then the display range is enlarged, but the apparatus size cannot be reduced and power consumption increases
Solution Approach 1:
The display device is divided into multiple independent display sections (first display section, second display section, third display section) that can be independently controlled. This allows the system to activate only the necessary display sections based on the unfolding state, reducing overall power consumption while maintaining adequate display area. For example, in the first unfolding state, only the first display section is activated, while in the second unfolding state, multiple sections are activated to provide larger display area when needed.
Solution Approach 2:
The display device employs dynamically adjustable unfolding states that change the configuration and activation of display sections based on usage requirements. The system transitions between different unfolding states (first, second, third states) where the display sections are selectively activated or deactivated. This dynamic adjustment allows the apparatus to optimize between power consumption and display area depending on the current state, rather than maintaining a fixed large display that consumes high power continuously.
2Adaptability or versatility
If multiple display sections are used to improve viewability from various angles, then viewability is enhanced, but the apparatus size and complexity increase
Solution Approach 1:
The display device is segmented into multiple independent display sections (first, second, and third display sections) that can be independently controlled and positioned. Each section can be selectively activated based on the unfolding state, providing enhanced viewability from different angles without requiring all sections to be active simultaneously. This segmentation allows the system to achieve versatility in viewing angles while managing complexity by activating only necessary sections.
Solution Approach 2:
The multiple display sections serve multiple functions depending on the unfolding state. The same physical display sections can provide different display areas and viewing angles based on which unfolding state is active. For instance, in the first unfolding state, the first display section provides a compact viewable area, while in the second unfolding state, additional sections expand the display area and viewing options. This multi-functionality allows a single display device structure to achieve various viewability configurations without requiring separate dedicated components for each function.
3Area of stationary object
If all display sections are activated to maximize display area, then display range is enlarged, but power consumption increases
Solution Approach 1:
The system activates only the necessary portion of display sections required for the current unfolding state rather than activating all sections continuously. In the first unfolding state, only the first display section is activated, providing adequate display area for compact usage. In the second unfolding state, additional sections are activated to provide larger display area when needed. This partial activation approach ensures that power consumption is proportional to the actual display area required, avoiding the waste of activating all sections when full display area is not needed.
Solution Approach 2:
The system changes the operational parameters of the display sections based on the unfolding state. The activation status, brightness, and content display parameters are dynamically adjusted according to which unfolding state is active. This parameter change allows the system to optimize the balance between display area and power consumption by matching the display section activation level with the current structural configuration and usage requirements.

AI summary
An electronic apparatus including a casing and a display device held on the casing at a holding position and including display sections each capable of independently displaying an image. The display sections include a first display section farthest from the holding position and at least one second display section including a display section held on the casing at the holding position. The display device is in one of a first state in which all angles each formed between adjacent display sections are larger than a first angle, a second state in which all the angles are smaller than a second angle smaller than the first angle, and a third state other than these states. When in the third state, an image is displayed on the first display section, and is not displayed on at least one of the second display sections.
