Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD-based display technologies face limitations in viewing angle and contrast due to transmissive backlighting, which restricts their effectiveness in creating immersive virtual environments, especially when viewed from different angles or in spaces with obstructions like doors and windows.
Innovation Solution
The use of emissive technologies such as micro-LED or Organic LED (OLED) for display panels, combined with modular diagonal designs and nano-infrared technology, allows for high-resolution, interactive, and seamless video displays that can be configured to fit various environments, including those with obstructions, using a virtual environment central computer for synchronized operation and user interface management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If transmissive LCD display technology is used, then display size can be increased, but viewing angle and contrast deteriorate
Solution Approach 1:
The patent replaces transmissive LCD technology with emissive display technology (micro-LED, OLED, or quantum dot LED). This substitution eliminates the need for backlighting mechanisms and uses self-emissive pixels that can be viewed from multiple angles without loss of contrast or brightness, thereby resolving the contradiction between large display size and viewing angle/contrast performance.
2Area of stationary object
If multiple display panels are used to cover large areas, then display coverage is improved, but seams and alignment issues worsen
Solution Approach 1:
The patent divides the large-area display into multiple modular display panels that can be independently manufactured and assembled. Each panel contains embedded alignment features and the system uses software-based image processing to detect and correct misalignments, allowing seamless tiling of panels across large surfaces while maintaining image continuity and reducing visible seams.
Solution Approach 2:
The patent incorporates alignment detection mechanisms that use feedback from camera systems or sensors to identify panel misalignments in real-time. The system then automatically adjusts image positioning and scaling for each panel based on detected deviations, ensuring seamless visual continuity across multiple panels while accommodating installation tolerances.
3Ease of manufacture
If fixed display configurations are used, then manufacturing simplicity is maintained, but adaptability to different environments worsens
Solution Approach 1:
The patent creates dynamically reconfigurable display systems where modular panels can be easily added, removed, or repositioned to adapt to different environmental requirements. The system includes software configuration capabilities that automatically detect panel arrangements and adjust display parameters, allowing the same standardized modules to serve various applications from fixed installations to flexible temporary displays.
Solution Approach 2:
The patent designs universal display panels that can function in multiple configurations and environments. Each panel is equipped with standardized interfaces and embedded sensors that enable the same hardware to adapt to different mounting scenarios, lighting conditions, and spatial arrangements, eliminating the need for custom-manufactured displays for each application while maintaining manufacturing simplicity.
