Stacked Display Panels Viewing Position Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic display devices with multiple panels face challenges in maintaining image accuracy due to positional variations of viewers, as the overlap of color and contrast pixels can change depending on the viewer's position, leading to inconsistent image display.
Innovation Solution
A display device comprising a first display panel with color pixels and a second display panel with contrast pixels, positioned in a stacked configuration, where an image processing unit generates color and contrast image data. The data generation includes an expansion based on the viewer's position to ensure accurate alignment and image formation, with the contrast image data being expanded to account for the viewing position, ensuring correct light filtering by contrast pixels for color pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple display panels are stacked to improve image quality, then image quality is improved, but alignment accuracy deteriorates due to positional variations of viewers
Solution Approach 1:
The patent applies dynamics by making the image data adaptive to the viewer's position. The image processing unit dynamically adjusts the image data for each display panel based on detected viewer position, allowing the system to maintain alignment accuracy despite positional variations. This transforms a static display system into a dynamic one that responds to viewer location.
Solution Approach 2:
The patent changes parameters by modifying image data based on viewer position parameters. When the viewer's position changes, the system adjusts parameters such as pixel alignment, brightness, and contrast for each panel to maintain optimal image quality. This parameter adaptation resolves the contradiction between maintaining high image quality and accommodating alignment variations.
2Measurement precision
If image data is adjusted based on viewer position to improve alignment accuracy, then alignment accuracy is improved, but device complexity increases
Solution Approach 1:
The image processing unit serves multiple functions: it processes image data, detects viewer position, calculates alignment adjustments, and controls multiple display panels. By making this single component multi-functional, the patent improves alignment accuracy without proportionally increasing overall device complexity.
Solution Approach 2:
The image processing unit acts as an intermediary between the viewer position detection and the display panels. It receives position information, processes it to determine appropriate adjustments, and then applies these adjustments to the image data before sending it to the panels. This intermediary role manages complexity by centralizing the adjustment logic in one component.
3Stability of the object's composition
If expansion based on viewing position is applied to improve image consistency, then image consistency is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-calculating and storing image data adjustments for different viewer positions. When a viewer's position is detected, the system can quickly retrieve and apply the pre-computed adjustments rather than calculating them in real-time, thus maintaining image consistency while reducing processing time.
Solution Approach 2:
The patent replaces complex real-time mechanical adjustment systems with computational methods. Instead of physically adjusting panel positions or orientations based on viewer location, the system uses image processing and data expansion algorithms to achieve the same effect, significantly reducing processing time while maintaining image consistency.
