Solution Overview

Problem

Current cylindrical lens-based stereoscopic display technologies face challenges with severe crosstalk due to misalignment of cylindrical lenses with light-emitting units, resulting in a poor display effect.

Innovation Solution

The display panel incorporates a cylindrical lens structure layer with strip-shaped cylindrical lens structures and a black matrix pattern featuring first and second openings. The second openings are strategically placed in non-crosstalk regions to increase light emission, reducing crosstalk by partitioning sub-pixel regions into non-crosstalk and crosstalk areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cylindrical lens structures are used for stereoscopic display, then depth perception is improved, but crosstalk between adjacent pixels increases due to misalignment

Engineering Contradiction:
Improvestereoscopic display capabilityVSAvoidcrosstalk
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent divides each sub-pixel region into multiple regions using focal lines, identifying a non-crosstalk region where light-emitting units are properly aligned with cylindrical lens structures. This segmentation allows the system to maximize the useful display area while minimizing crosstalk effects in the identified non-crosstalk region.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces second openings specifically in the non-crosstalk regions where proper alignment occurs, while maintaining first openings in other regions. This local differentiation optimizes light emission in specific areas where alignment is successful, improving overall display quality without exacerbating crosstalk issues.

Inventive Principle:
Principle #3Local quality

2Object-generated harmful factors

If black matrix pattern blocks light to prevent crosstalk, then crosstalk is reduced, but light-emitting area decreases

Engineering Contradiction:
ImprovecrosstalkVSAvoidlight-emitting area
Core Design Contradiction:
Object-generated harmful factorsVSArea of stationary object

Solution Approach 1:

The patent applies different opening configurations to different regions: second openings are placed specifically in non-crosstalk regions where proper alignment occurs, allowing light emission in these safe zones, while first openings remain in other regions. This localized approach maximizes light-emitting area while maintaining crosstalk suppression.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

By segmenting the sub-pixel region into non-crosstalk regions and crosstalk regions, the patent can strategically place second openings only where they are safe to do so, optimizing the balance between light emission and crosstalk prevention.

Inventive Principle:
Principle #1Segmentation
