Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in integrating functional components, such as cameras or sensors, within the display area while maintaining aesthetic appeal and functional integrity.
Innovation Solution
A display panel design that includes an opening area surrounded by a display area, with components like cameras or sensors positioned within this opening, and an input sensing layer to detect external inputs, along with an optical functional layer to reduce external light reflection and enhance light emission efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an opening is provided in the display area to integrate functional components (camera, sensor), then component integration capability is improved, but structural stability and aesthetic appearance deteriorate
Solution Approach 1:
A support structure is introduced as an intermediary element between the display panel layers and the functional components positioned in the opening. This support structure provides mechanical reinforcement to maintain structural stability while allowing the opening to exist for component integration, thus resolving the contradiction between adaptability and structural stability.
2Adaptability or versatility
If an opening is provided in the display area to integrate functional components, then component integration capability is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The display panel is designed with different structural characteristics in different regions. The opening is strategically positioned and sized to accommodate functional components while minimizing impact on the overall aesthetic appearance. The support structure is also designed with appropriate visual properties to blend with the surrounding display area, thus resolving the contradiction between adaptability and aesthetic appearance.
3Adaptability or versatility
If the display area is reduced to accommodate openings for functional components, then component integration is improved, but display area deteriorates
Solution Approach 1:
Instead of reducing the display area in the two-dimensional plane, the design utilizes the third dimension by positioning functional components in openings that extend through the thickness of the display panel. This allows functional components to be integrated without significantly compromising the display area, thus resolving the contradiction between adaptability and display area.
