Stereo Display Light Shieldable Element Cross-Talk Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stereo display techniques suffer from cross-talk phenomena, where the left eye receives right eye image information or vice versa, resulting in undesirable stereo image quality due to the lack of effective light shielding mechanisms.
Innovation Solution
A stereo display system incorporating a light shieldable element with a specific light-shielding matrix structure that shields scan lines, data lines, and pixel electrode regions, ensuring that only intended image information reaches each eye, thereby minimizing cross-talk by controlling the light-shielding percentage and positioning relative to the sub-pixel regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light shieldable element is added to shield scan lines and data lines, then cross-talk is reduced, but device complexity increases
Solution Approach 1:
The light shieldable element is integrated directly into the display panel structure, merging the shielding function with the existing pixel electrode and substrate layers. This eliminates the need for separate external shielding components, thereby reducing device complexity while maintaining cross-talk reduction effectiveness.
Solution Approach 2:
The light shieldable element serves multiple functions simultaneously: it shields scan lines, shields data lines, and shields pixel electrode regions. By combining multiple shielding functions into a single element, the overall device complexity is reduced compared to implementing separate shielding structures for each component.
2Object-affected harmful factors
If the light shieldable element shields more regions, then cross-talk is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The light shieldable element employs different shielding strategies for different regions: it provides full shielding for scan lines and data lines, while providing selective partial shielding for pixel electrode regions based on their specific cross-talk risks. This localized approach to shielding quality reduces manufacturing precision requirements compared to uniform full shielding across all regions.
Solution Approach 2:
Instead of shielding the entire pixel electrode region uniformly, the light shieldable element applies partial shielding only to specific portions of pixel electrodes that are most prone to causing or receiving cross-talk. This partial action approach reduces the stringent precision requirements that would result from complete uniform shielding.
3Object-affected harmful factors
If the light shieldable element is positioned closer to the sub-pixel regions, then cross-talk is reduced, but the area available for other components decreases
Solution Approach 1:
The light shieldable element utilizes the vertical dimension by being positioned between the substrate and the color filter layer, rather than only occupying horizontal space within the pixel electrode plane. This vertical positioning allows effective cross-talk shielding while preserving horizontal area for other components.
Solution Approach 2:
The light shieldable element is nested within the existing display panel layer structure, fitting between the substrate and the color filter layer. This nesting approach allows the shielding element to be incorporated without adding external bulk or reducing the overall area available for other components.

AI summary
A stereo display including a display panel and a light shieldable element is provided. The display panel has at least two sub-pixel regions. Each sub-pixel region is configured with at least a first pixel electrode to define a first sub-region. The light shieldable element is disposed in front of the sub-pixel regions. Each first pixel electrode has a first shieldable region shielded by the light shieldable element and a first non-shielding region exposed by the light shieldable element. The first shieldable region is closer to the scan line than the first non-shielding region. A horizontal direction is defined as a connection line of two eyes of a user watching the stereo display. A total length A of each sub-pixel region and a length B of the first shieldable region in a predetermined direction intersected to the horizontal direction comply with a relationship that (B/A)×100% is substantially from 1.61% to 47.9%.
