Foldable Display Multi-Stage Luminance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it inconvenient to navigate and switch pages in electronic devices, such as e-books, web documents, and notes, as they require both hands to perform drag or swipe operations, limiting usability when both hands are occupied.
Innovation Solution
A foldable electronic device equipped with sensor circuits to detect folding and holding, allowing content to be displayed in multiple columns and pages, enabling one-handed page switching by adjusting luminance and orientation based on user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is displayed in units of one page, then the display area is maximized, but page switching requires two hands which reduces ease of operation
Solution Approach 1:
The display is segmented into multiple columns, each showing a different page of content. This allows the user to view multiple pages simultaneously and switch between them by simple horizontal gestures, enabling one-handed operation while maintaining ease of use.
Solution Approach 2:
The patent transitions from a single-page vertical display to a multi-column horizontal display arrangement. This dimensional change allows page switching to be performed through horizontal gestures rather than requiring precise vertical drag or swipe operations, improving one-handed operability.
2Use of energy by moving object
If both pages are displayed with high luminance, then visibility is improved, but power consumption increases
Solution Approach 1:
Different luminance levels are applied to different pages based on their visibility requirements. The active page (currently being viewed) is displayed with high luminance for optimal visibility, while inactive pages are displayed with reduced luminance to minimize power consumption. This local differentiation resolves the contradiction between visibility and energy efficiency.
Solution Approach 2:
The luminance parameter of the display is dynamically adjusted based on the operational state. When the device is held in a specific orientation or folded state, the system changes the luminance parameter of different page regions to optimize both visibility of the active content and power consumption efficiency.
