Flexible Display Unit Deflection Detection and Region Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display units often fail to align the visible and display portions correctly when bent, leading to privacy issues and unnecessary electricity consumption as the non-visible portion continues to display images.
Innovation Solution
A display unit with a detection section to determine the deflection amount and direction, a determination section to identify visible and non-visible portions, and a control section to manage display content accordingly, ensuring that only the visible portion is actively displayed and the non-visible portion is either stopped or displays a fixed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the display unit is made flexible to reduce thickness and weight, then the substrate can be thinner and lighter, but the display portion and visible portion do not correspond when bent
Solution Approach 1:
The patent divides the display section into multiple independent regions (first display region, second display region, third display region) that can be controlled separately. This segmentation allows the system to manage which regions are visible and which are hidden when the display is bent, resolving the alignment issue between display portion and visible portion.
Solution Approach 2:
The patent implements dynamic control of display regions based on the bending state of the flexible display. The control section dynamically adjusts which regions display content based on detected deflection, allowing the display to adapt its visible and hidden portions according to its physical state.
2Productivity
If the entire display section continues to display images, then the display function is maintained, but electricity is consumed unnecessarily in the non-visible portion
Solution Approach 1:
The patent applies partial action by activating only the necessary display regions (visible portions) while keeping hidden regions inactive. The control section selectively controls the first, second, and third display regions based on which portions are visible, avoiding unnecessary power consumption in hidden areas while maintaining display functionality where needed.
3Area of stationary object
If the non-visible portion displays images, then the display section is fully utilized, but privacy is compromised as images are exposed to unintended viewers
Solution Approach 1:
The patent applies different display qualities to different regions of the display section. Visible regions (first display region) display content with full functionality, while hidden regions (second and third display regions) are controlled to not display images or display different content, ensuring privacy protection in areas that are not visible to the user.

AI summary
A display unit has a flexible display section, a detection section for detecting a deflection amount and a deflection direction of the display section, a determination section for determining a visible portion and a non-visible portion of the display section based on the deflection amount and the deflection direction, and a control section for controlling display contents of the display section. The control section either prevents an image display on the non-visible portion or displays one of a fixed image or a pre-set moving image on the non-visible portion. The display unit also includes a displacement sensor located in the same region as the display section.
