VSEngineering 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

Engineering Contradiction:
Improvedisplay mode flexibilityVSAvoidimage resolution
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

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.

Inventive Principle:
Principle #15Dynamics

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.

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.

Inventive Principle:

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.
