Solution Overview

Problem

Current 3D display technologies face challenges in achieving high spatial resolution and low signal frequency while maintaining image quality, as they often sacrifice spatial resolution or experience brightness and frequency issues in autostereoscopic displays.

Innovation Solution

A hybrid multiplexed 3D display system that includes an image display, a light source, and an image splitter, where the light source generates sequential colors transmitted through the image display, and the image splitter directs image data towards multiple view directions, combining spatial and temporal multiplexing to enhance stereoscopic visual effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If spatial multiplexed display is used to display 3D images on multi-view autostereoscopic display, then multiple views can be provided simultaneously, but spatial resolution of single view is greatly reduced

Engineering Contradiction:
Improvemulti-view capabilityVSAvoidspatial resolution
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies temporal multiplexing by sequentially displaying different color components (RGB frames) over time rather than simultaneously. The display controller alternates between red, green, and blue frames in rapid succession, and the human visual system integrates these sequential frames into a complete color image. This periodic temporal action resolves the contradiction by providing multi-view capability through time-sequential display while maintaining full spatial resolution for each color component.

Inventive Principle:
Principle #19Periodic action

2Manufacturing precision

If temporal multiplexed display is used to display 3D images, then spatial resolution is maintained, but brightness is seriously decreased and signal frequency is too high

Engineering Contradiction:
Improvespatial resolutionVSAvoidbrightness
Core Design Contradiction:
Manufacturing precisionVSIllumination intensity

Solution Approach 1:

The patent applies spatial multiplexing by pre-arranging color filter arrays and liquid crystal pixel structures that can simultaneously modulate multiple color components. The display panel is designed with sub-pixels and color filters positioned to allow simultaneous or near-simultaneous display of RGB components, thereby preliminarily preparing the optical path to reduce the need for rapid temporal switching. This preliminary spatial arrangement maintains brightness by reducing temporal multiplexing requirements while preserving spatial resolution.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If 3D display modulates colors, brightnesses and views simultaneously, then complete 3D image information is provided, but bandwidth becomes too high

Engineering Contradiction:
Improve3D image informationVSAvoidbandwidth
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The patent segments the 3D image information into separate color component frames (red, green, blue) that are displayed sequentially in time. Instead of transmitting and displaying all color, brightness, and view information simultaneously, the system divides the complete image into multiple temporal segments (color frames). This segmentation reduces instantaneous bandwidth requirements while preserving all 3D image information through the sequential presentation of color components that the human visual system integrates.

Inventive Principle:
Principle #1Segmentation

AI summary

A hybrid multiplexed 3D display and a displaying method thereof. The hybrid multiplexed 3D display includes an image display, a light source and an image splitter. The image display generates a view image. The light source sequentially generates light of multiple colors transmitted through the image display. The image splitter disposed above or below the image display causes image data, which is generated after the light is transmitted through the image display, to emit toward two or more than two view directions. Thus, the image viewed by a user has at least two views to achieve a stereoscopic visual effect.
