Foldable Display Light Transmittance for Folded Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-folding type foldable display devices pose challenges in accessing and interacting with displayed information when fully folded, as users find it difficult to check information or input commands without an additional display panel.
Innovation Solution
A foldable display device design that incorporates a light transmitting area in the support structure, equipped with an input sensor, allowing users to view and interact with displayed information when folded by using the sensor to control applications through the transparent area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an additional display panel is disposed on the surface of the support structure opposite to the display panel, then users can check displayed information when the device is folded, but the device complexity, production cost, thickness, and power consumption increase
Solution Approach 1:
The patent uses a light transmitting area that allows users to view information from the opposite display surface through light transmission, rather than adding a physical display panel. This copying approach enables information access through optical means, reducing structural complexity while maintaining functionality.
Solution Approach 2:
The patent extracts the essential function of displaying information from a separate physical display panel and integrates it into the existing support structure through a light transmitting area. This extraction eliminates the need for additional display components while preserving the core functionality of information accessibility.
2Ease of operation
If an additional display panel is disposed on the surface of the support structure opposite to the display panel, then users can check displayed information when the device is folded, but the production cost increases
Solution Approach 1:
The patent implements information viewing functionality through a light transmitting area in the support structure, copying the display function through optical transmission rather than requiring an additional physical display panel. This approach significantly reduces production costs by eliminating expensive display components.
Solution Approach 2:
The support structure is given multiple functions: it provides structural support and simultaneously enables information viewing through its light transmitting area. This multi-functionality eliminates the need for separate display components, reducing production costs while maintaining accessibility when folded.
3Ease of operation
If an additional display panel is disposed on the surface of the support structure opposite to the display panel, then users can check displayed information when the device is folded, but the thickness of the device increases
Solution Approach 1:
The patent extracts the display viewing function from a separate physical panel and integrates it into the existing support structure through a light transmitting area. This extraction eliminates the need for additional thickness from separate display components while maintaining the ability to view information when folded.
Solution Approach 2:
The support structure serves dual purposes: providing structural support and enabling information viewing through light transmission. This multi-functionality allows information accessibility when folded without adding the thickness that would result from an additional display panel.
4Ease of operation
If an additional display panel is disposed on the surface of the support structure opposite to the display panel, then users can check displayed information when the device is folded, but the power consumption increases
Solution Approach 1:
The patent copies the display information viewing function through light transmission via the light transmitting area in the support structure, rather than using an additional power-consuming display panel. This approach reduces power consumption by eliminating the need for separate display drivers and backlights.
Solution Approach 2:
The support structure provides both structural support and information viewing capabilities through light transmission. This multi-functionality eliminates the need for an additional power-consuming display system while maintaining accessibility to displayed information when folded.
