Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable display apparatuses face challenges in efficiently transmitting signals and minimizing interference of light and sound when folded, due to the design of transmission areas and components, which affects the display quality and functionality.
Innovation Solution
A foldable display apparatus is designed with specific transmission areas and structures that allow components like cameras, sensors, and speakers to overlap with transmission areas, utilizing holes and layers to transmit signals while minimizing interference, and includes a flexible display panel with a unique arrangement of pixels and transmission structures to optimize display and functionality when folded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are placed between the case and display panel, then device functionality is improved, but light interference increases when folded
Solution Approach 1:
The patent introduces transmission areas in the display panel that extend into the display area, creating a new spatial dimension for light passage. This allows light to travel through the display panel itself rather than being blocked by components, resolving the contradiction between component placement and light transmission.
Solution Approach 2:
The transmission areas act as intermediaries between the components and the external environment. These areas allow light to pass through the display panel to reach components like cameras and sensors, mediating between the need for component functionality and the need for unobstructed light paths.
2Reliability
If transmission areas are disposed inside the display area, then signal transmission is improved, but display area is reduced
Solution Approach 1:
The patent applies local quality by creating specific transmission areas with light-transmissive properties within the display panel. These areas have different optical characteristics than the surrounding display regions, allowing light to pass through selectively at specific locations while maintaining normal display functionality elsewhere.
Solution Approach 2:
The transmission areas function similarly to porous materials by providing pathways for light transmission. The display panel incorporates regions with sufficient optical transparency to allow light to pass through to components, while maintaining structural integrity and display functionality.
3Reliability
If multiple transmission areas are symmetrically disposed, then light transmission is improved, but manufacturing complexity increases
Solution Approach 1:
While the patent describes symmetrical arrangements of transmission areas, the core innovation allows for flexible configurations. The transmission areas can be positioned at different locations and with different dimensions depending on component requirements, providing manufacturing flexibility while achieving effective light transmission.
Applied Scientific Principles

Function Achieved in This Case
The solution enhances signal transmission and reduces interference, maintaining display quality and functionality when the apparatus is folded, by ensuring that the transmission areas effectively pass light and sound while minimizing disruptions, thus improving user experience.
Implementation Method 1
each of the first transmission area and the second transmission area overlaps the component, when the foldable display apparatus is folded... light emitted from the component or received by the component passes through the at least one first transmission area and the at least one second transmission area

AI summary
A foldable display apparatus may include a first display panel and a component. The first display panel may include a first section and a second section. The first section may include a first pixel set and a first transmission structure surrounded by the first pixel set. The second section may include a second pixel set, may include a second transmission structure surrounded by the second pixel set, and may rotate relative to the first display section about a folding axis. A distance from the folding axis to a center of the first transmission structure may be substantially equal to a distance from the folding axis to a center of the second transmission structure. The component may overlap the first transmission structure. The second transmission structure may overlap the first transmission structure and the component when the foldable display apparatus is in a folded state.
