Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a beam splitter lens is used in a three-dimensional display device, then three-dimensional image display is enabled, but image resolution is reduced and distortion occurs when displaying two-dimensional images
Solution Approach 1:
The patent applies dynamics by making the display system adaptable between two display modes (three-dimensional and two-dimensional) through a switching mechanism. The system dynamically adjusts its operation based on the input image type, allowing the same hardware to optimize for different display requirements without permanent structural changes.
Solution Approach 2:
The patent changes parameters by adjusting pixel brightness values based on the display mode. When in two-dimensional mode, the system modifies brightness parameters of pixels according to correction algorithms to compensate for the beam splitter lens impact, thereby maintaining image resolution and reducing distortion while keeping the physical structure unchanged.
2Adaptability or versatility
If a beam splitter lens is used in a three-dimensional display device, then three-dimensional image display is enabled, but image distortion occurs when displaying two-dimensional images
Solution Approach 1:
The patent changes parameters by applying correction algorithms that adjust brightness values of pixels based on their positions and the display mode. This parameter adjustment compensates for geometric distortion caused by the beam splitter lens when displaying two-dimensional images, restoring proper image shape and geometry.
3Reliability
If the display panel is optimized for three-dimensional images, then stereoscopic display performance is improved, but two-dimensional image quality deteriorates
Solution Approach 1:
The system dynamically adapts its processing based on the display mode through a switching mechanism. When two-dimensional images are detected, the system activates correction algorithms that adjust pixel brightness to compensate for beam splitter lens effects, thereby maintaining two-dimensional image quality while preserving three-dimensional display capabilities.
Solution Approach 2:
The patent applies parameter changes by modifying brightness values of pixels according to correction algorithms specific to two-dimensional display mode. This allows the display panel to optimize its output for two-dimensional images when needed, without compromising the underlying three-dimensional display optimization.
