3D Display Light Source Layout to Reduce Image Crosstalk

Solution Overview

Problem

Existing three-dimensional display techniques suffer from image crosstalk due to interference between light from different directions provided by directional light sources.

Innovation Solution

An electronic device with a display panel and a light source module featuring alternately arranged groups of light-emitting units that emit light independently to alternately display different view field image information, reducing interference and enhancing stereoscopic display effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If directional light sources are used to achieve stereoscopic display effects, then the stereoscopic visual effect is improved, but image crosstalk occurs due to interference between light from different directions

Engineering Contradiction:

Improvestereoscopic display effectVSAvoidimage crosstalk

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The light source module is divided into multiple independent light-emitting units that can be controlled separately. Each light-emitting unit corresponds to specific display pixels and can emit light independently, allowing precise control over which pixels receive light from which direction, thereby eliminating image crosstalk while maintaining stereoscopic display effects.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic control where different groups of light-emitting units are activated at different time periods. The controller selectively turns on specific light-emitting units based on the display content and viewing angle requirements, enabling the system to adaptively prevent light interference and reduce image crosstalk while preserving the stereoscopic effect.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple light-emitting units are used to provide light from different directions, then stereoscopic display capability is improved, but light interference between different directions causes image crosstalk

Engineering Contradiction:

Improvestereoscopic display capabilityVSAvoidimage quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The light source module is divided into multiple independent light-emitting units that can be controlled separately. Each light-emitting unit corresponds to specific display pixels and can emit light independently, allowing precise control over which pixels receive light from which direction, thereby eliminating image crosstalk while maintaining stereoscopic display effects.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The controller selectively activates specific light-emitting units based on the display content and viewing angle requirements. This feedback-based control ensures that only the necessary light-emitting units are turned on at any given time, preventing light interference and maintaining high image quality while providing versatile stereoscopic display capability.
