Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with parallax barriers suffer from crosstalk issues due to complex configurations, which are difficult to implement and reduce image quality when displaying images from multiple viewpoints.
Innovation Solution
A display device configuration featuring a liquid crystal display panel with pixels and a light source having light emission points, where the ratio of pixel pitch to light emission point pitch is 1:4n or 1:6n, allowing for a simpler mechanism to reduce crosstalk by optimizing the positional arrangement of pixels and light emission points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pixels are simply alternately arranged for two viewpoints, then the configuration is simple, but crosstalk occurs and image quality deteriorates
Solution Approach 1:
The patent applies parameter changes by establishing a specific mathematical relationship between pixel pitch and light emission point pitch (ratio of 1:4n or 1:6n). This quantitative parameter optimization resolves the contradiction by maintaining simple alternating arrangement while eliminating crosstalk through precise pitch ratio control, thus improving image quality without increasing configuration complexity
Solution Approach 2:
The patent introduces a new dimensional consideration by adding the light emission point pitch as a separate spatial parameter to optimize alongside pixel pitch. This dimensional expansion allows the system to achieve crosstalk reduction not through complex arrangement patterns, but through optimized spacing relationships in the horizontal dimension
2Object-affected harmful factors
If strict optical property restrictions are imposed on the panel to reduce crosstalk, then crosstalk is reduced, but the mechanism becomes complicated and difficult to implement
Solution Approach 1:
The patent shifts the approach from restricting optical properties to optimizing geometric parameters. By controlling the pitch ratio between pixels and light emission points (1:4n or 1:6n), the system achieves crosstalk reduction through simple dimensional relationships rather than complex optical property constraints, making the mechanism easier to manufacture and implement
Solution Approach 2:
The patent replaces optical property restrictions with a geometric arrangement solution. Instead of modifying the optical characteristics of the panel, the invention uses a mathematically optimized spatial arrangement of light emission points relative to pixels, substituting complex optical control with simpler geometric positioning
