Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As urbanization increases, more people are confined to environments without windows, leading to negative impacts on psychological and physiological health due to the lack of natural light and scenic views, necessitating a display device that can simulate window views and project natural light.
Innovation Solution
A display device with a display panel featuring pixels that include both illumination and display units, where the illumination unit has sub-pixels and light orientation elements to project light directly or indirectly from the display surface, and the display unit emits light to create a simulated window view and natural light experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device integrates both illumination and display functions, then the versatility and applicability of the device is improved, but the device complexity increases
Solution Approach 1:
The patent combines illumination units and display units into a single pixel structure, where each pixel contains both illumination sub-pixels and display sub-pixels. This merging allows the display device to simultaneously perform illumination and display functions, thereby improving versatility while managing complexity through integrated design
Solution Approach 2:
The display device is designed to perform multiple functions: it can display images through the display unit and project illumination light through the illumination unit. This multi-functionality allows the same device to serve both as a display screen and as a light projection device, enhancing adaptability across different application scenarios
2Manufacturing precision
If light orientation elements are added to control illumination direction, then the precision of light projection is improved, but the manufacturing complexity increases
Solution Approach 1:
The illumination unit is divided into multiple illumination sub-pixels, each equipped with its own light orientation element. This segmentation allows independent control of light direction from each sub-pixel, achieving precise light projection. The modular structure also simplifies the overall manufacturing process by allowing standardized components to be assembled systematically
