Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional stereo display technologies suffer from crosstalk between left-eye and right-eye stereoscopic images, leading to inconsistent image display quality due to fixed compensation parameters that result in under or over compensation across different areas of the display panel.

Innovation Solution

A method that generates and applies specific left-eye and right-eye crosstalk parameters based on image data to calibrate and display stereoscopic images, using look-up tables to adjust for grey level differences and prevent over/under compensation, ensuring optimal image quality.

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed crosstalk compensation parameter is used, then the compensation process is simple, but it results in under compensation and over compensation in different areas of the stereo display panel

Engineering Contradiction:

Improvecompensation process simplicityVSAvoidcrosstalk compensation uniformity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by transitioning from a fixed crosstalk compensation parameter to a dynamic parameter that varies across different regions of the display panel. The display panel is divided into multiple regions, and each region has its own specific crosstalk compensation parameter, allowing the compensation to adapt to spatial variations in crosstalk characteristics across the panel surface.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements local quality by assigning different crosstalk compensation parameters to different regions of the display panel. Instead of using a uniform parameter across the entire panel, the invention creates region-specific parameters that account for local variations in crosstalk, ensuring optimal compensation performance in each area.

Inventive Principle:

Principle #3Local quality

2Device complexity

If conventional stereo display technologies are used, then the display structure is simple, but it cannot completely separate left-eye and right-eye stereoscopic images, leading to crosstalk

Engineering Contradiction:

Improvedisplay structure complexityVSAvoidcrosstalk between eyes

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by modifying the crosstalk compensation parameters based on the specific characteristics of the display panel and viewing conditions. By adjusting these parameters dynamically for different regions and conditions, the system reduces crosstalk without requiring fundamental changes to the display structure or adding complex separation mechanisms.
