Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current 3D image display technologies suffer from reduced quality due to crosstalk when displaying mixed images, limiting the ability for multiple observers to experience high-quality 3D effects simultaneously.

Innovation Solution

A method and apparatus that sequentially display left and right frame images on a display panel, using a light source module to selectively emit light only when displaying individual eye images, while blocking light during mixed image display to prevent crosstalk, utilizing a polarization panel and glasses with synchronized shutters to ensure proper image viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a mixed image including left eye image and right eye image is displayed on the display panel, then the display coverage is improved, but crosstalk is generated and the quality of the 3D display is deteriorated

Engineering Contradiction:

Improvedisplay coverageVSAvoid3D display quality

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by converting the mixed image into separate left eye image and right eye image data before display. The image processing unit performs this conversion in advance, so that when the display panel shows the mixed image, the light source module can selectively block light for specific regions, preventing crosstalk while maintaining full display coverage.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces the light source module as an intermediary between the display panel and the observer's eyes. This light source module selectively blocks light from specific display blocks, acting as a mediator that prevents crosstalk from reaching the observer while allowing the full mixed image to be displayed on the panel.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the liquid crystal shutters are opened and closed in accordance with the displayed image, then the 3D image is embodied, but crosstalk is generated in areas where mixed image is displayed

Engineering Contradiction:

Improve3D image embodimentVSAvoidcrosstalk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes the harmful crosstalk component by using the light source module to selectively block light from display blocks showing mixed images. This extraction approach separates the useful 3D image information from the harmful crosstalk, allowing the liquid crystal shutters to function properly without generating crosstalk.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the potential harm of mixed image display into a benefit by using the mixed image data to control the light source module. The mixed image information, which would normally cause crosstalk, is instead used to intelligently control which light blocks are blocked, transforming the problem into a solution that maintains both display coverage and image quality.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A method for displaying a three-dimensional (“3D”) image, wherein the method includes; sequentially displaying a left frame image corresponding to a left eye and a right frame image corresponding to a right eye on a display panel, blocking a light provided to a display block of the display panel when the display block displays a mixed image which includes a left eye image of the left frame image corresponding to the left eye and a right eye image of the right frame image corresponding to the right eye, and providing the light to the display block of the display panel when the display block displays only one of the left eye image and the right eye image.
