Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels that support both 2D and 3D displays face a challenge in maintaining resolution in 2D display mode due to the presence of light-splitting structures like grating or columnar lenses, which affect the display effect.
Innovation Solution
A display panel design that includes a light-splitting component with light-splitting members arranged along a specific direction, where the distance between adjacent members is optimized based on the angular resolution and optimal viewing distance of the human eye, ensuring that the light-splitting members are imperceptible in 2D mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a grating structure or columnar lens structure is used for light-splitting in 3D display, then 3D display capability is achieved, but resolution in 2D display mode is reduced
Solution Approach 1:
The patent changes the parameters of the light-splitting members by precisely controlling their width and spacing to satisfy specific mathematical relationships with human eye resolution and viewing distance. This parameter optimization ensures that the light-splitting structure remains imperceptible in 2D mode while functioning properly in 3D mode.
Solution Approach 2:
The patent applies different functional characteristics to the light-splitting members based on their position and dimensions. By making the members narrow and closely spaced, the structure provides 3D functionality where needed while maintaining uniform appearance across the display surface in 2D mode.
2Measurement precision
If light-splitting members are made smaller and closer together to improve 2D display effect, then resolution is maintained, but 3D display functionality may be compromised
Solution Approach 1:
The patent establishes specific parameter relationships between the width of light-splitting members, the distance between adjacent members, and the characteristics of human vision (angular resolution and optimal viewing distance). These mathematically optimized parameters ensure that the structure is imperceptible at normal viewing distances while still providing effective light-splitting for 3D display.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the 2D display effect by preventing the perception of light-splitting members in 2D mode, while maintaining compatibility with 3D display, thus improving the overall display performance.
Implementation Method 1
light-splitting is often realized through a grating structure or a columnar lens structure for the 3D display
Implementation Method 2
The naked-eye 3D display mainly uses the principle of binocular parallax, that is, by adjusting the optical path of the outgoing light
