Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display panel is evaluated based only on the display panel without additional optical components, then the evaluation process is simple, but the reliability of the evaluation is reduced because the measured image differs from what actual users perceive
Solution Approach 1:
The patent introduces an evaluation lens as an intermediary component between the display panel and the measurement system. This lens refracts light from the display panel to create an evaluation image that simulates what actual users would perceive through the stereoscopic display device, thereby improving evaluation reliability without requiring the full complex stereoscopic device assembly
Solution Approach 2:
The evaluation system creates a copied version of the user-perceived image through the evaluation lens. By refracting light to form an evaluation image that replicates the visual experience of actual users, the system captures the essential optical characteristics without needing to evaluate the complete stereoscopic device, thus improving reliability while managing complexity
2Measurement precision
If the evaluation lens refracts light to match user perception, then the evaluation accuracy improves, but the system complexity increases due to additional optical components and alignment requirements
Solution Approach 1:
The evaluation lens serves as a simplified intermediary that replicates the essential light-refracting function of the full stereoscopic device. It creates an evaluation image with accurate luminance characteristics without requiring the complete optical assembly, thereby improving measurement precision while limiting complexity increase to a single lens component
Solution Approach 2:
The patent extracts the essential light-refracting function from the complete stereoscopic display device and isolates it in the evaluation lens. This allows the system to capture the critical optical characteristics needed for accurate luminance measurement without incorporating all the complexity of the full device assembly
