Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display device is designed to maintain high transparency, then the transmittance is improved, but the display brightness and contrast deteriorate
Solution Approach 1:
The patent applies dynamic brightness adjustment by controlling the backlight unit to adapt to different viewing conditions. The system dynamically regulates the brightness of the backlight source to maintain optimal display contrast while preserving transparency, resolving the contradiction between fixed transparency and variable display performance.
Solution Approach 2:
The patent changes the brightness parameter of the backlight unit dynamically. By adjusting the backlight intensity as a variable parameter rather than a fixed value, the system can optimize both transparency and display brightness/contrast according to different operating conditions, thus resolving the technical contradiction.
2Adaptability or versatility
If different manufacturers use varying test conditions, then device adaptability is improved, but measurement precision deteriorates
Solution Approach 1:
The patent creates a universal test method that can evaluate multiple types of transparent display devices (LCD and OLED) using the same standardized procedure. The test system incorporates multiple measurement functions including transmittance, contrast ratio, and brightness measurements, enabling consistent evaluation across different device types and manufacturers.
Solution Approach 2:
The patent systematically varies test parameters such as viewing angles (0°, 45°, 85°), measurement distances, and brightness levels to establish comprehensive evaluation criteria. By defining specific parameter ranges and measurement conditions, the method achieves both broad device compatibility and precise performance measurement.
