Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chromatic aberration 3D display technology is used with color filter lenses, then a 3D stereoscopic effect is achieved, but resolution is reduced and color offsets are generated at picture edges
Solution Approach 1:
The backlight module is segmented into multiple independent light emitting units (red, green, blue LEDs) that can be independently controlled. This segmentation allows different color channels to be activated separately for different eyes, enabling high-resolution 3D display without color mixing at edges
Solution Approach 2:
The patent employs periodic activation of different color LEDs in synchronization with the shutter glasses. The backlight module alternates between displaying images for left eye and right eye with periodic timing, achieving 3D effect while maintaining high resolution through time-division multiplexing
2Reliability
If chromatic aberration 3D display technology is used with color filter lenses, then a 3D stereoscopic effect is achieved, but color offsets are generated at picture edges
Solution Approach 1:
Different regions of the display have different color characteristics optimized for their function. The backlight module uses locally controlled LED units that emit specific colors only where needed, eliminating color offset at edges by preventing color mixing in critical display regions
Solution Approach 2:
The patent dynamically changes color emission by controlling different LED units (red, green, blue) to emit their respective colors at different time intervals. This color switching synchronized with shutter glasses eliminates persistent color offsets while maintaining accurate color perception for 3D viewing
3Ease of operation
If traditional 3D glasses with color filters are used, then 3D viewing is enabled, but long-term viewing easily causes vertigo
Solution Approach 1:
The system dynamically switches between different color LED emissions and synchronizes with the shutter glasses timing. This dynamic adaptation creates a more natural viewing experience that reduces visual fatigue and vertigo during long-term viewing while maintaining 3D capability
Solution Approach 2:
The patent changes key parameters including emission timing, color wavelength, and intensity distribution to optimize viewing comfort. By adjusting these parameters dynamically, the system reduces harmful effects like vertigo while preserving 3D viewing functionality
