Light Guide Plate Layout for Transparent Stereoscopic Line Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light guide plates struggle to maintain transparency while displaying stereoscopic images nearly parallel to the incident surface, leading to reduced clarity and difficulty in displaying continuous line images due to increased deflector density.
Innovation Solution
A light guide plate design with multi-intersection arrangement lines where light deflectors intersect at multiple points for each eye position, ensuring clear display of stereoscopic images by maintaining consistent light amount and direction, and using a controller to manage light sources for enhanced image control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the row spacing of deflectors is narrowed to display stereoscopic images nearly parallel to the incident surface, then the stereoscopic image display capability is improved, but the transparency of the light guide plate is reduced
Solution Approach 1:
The light guide plate is divided into multiple regions with different deflector arrangements. The first region (near incident surface) uses a first deflector arrangement with larger row spacing to maintain transparency, while the second region (farther from incident surface) uses a second deflector arrangement with smaller row spacing to enable stereoscopic image display. This spatial segmentation allows each region to optimize for its specific function.
Solution Approach 2:
Different regions of the light guide plate are assigned different local properties: the first region has deflectors configured for transparency and general light guidance, while the second region has deflectors configured for stereoscopic image display with appropriate row spacing. Each local region has optimized qualities suited to its specific operational requirements.

3Adaptability or versatility
If the deflector density is increased to display stereoscopic images with high parallelism to the incident surface, then the stereoscopic image display capability is improved, but the continuity of line images is lost
Solution Approach 1:
The light guide plate is divided into multiple regions with different deflector arrangements. The first region (near incident surface) uses a first deflector arrangement with larger row spacing to maintain transparency, while the second region (farther from incident surface) uses a second deflector arrangement with smaller row spacing to enable stereoscopic image display. This spatial segmentation allows each region to optimize for its specific function.
Solution Approach 2:
The inclined surfaces of the deflectors are designed with curved profiles rather than straight lines. This curvature allows the deflectors to smoothly redirect light rays, maintaining continuous line image appearance even when deflectors are densely packed. The curved geometry enables gradual light redirection without creating visible discontinuities.

Function Achieved in This Case
The design allows for clear and continuous display of stereoscopic images nearly parallel to the incident surface with consistent light distribution, reducing variations in light amount and enhancing image clarity.
Implementation Method 1
light from the light source is incident through the incident surface, which is a side surface, and where the light is guided while being totally reflected inside
Implementation Method 2
the light is reflected and emitted from the emission surface
Implementation Method 3
a plurality of light deflectors that deflect the light that is incident from the incident surface and guided and cause it to be emitted from the emission surface
