Autostereoscopic Display Diffusion Board Trenches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autostereoscopic display technologies face issues such as increased execution costs, unnatural binocular vision, and color separation due to the expansion of pixels and black matrices, leading to a blotted stereoscopic vision effect.
Innovation Solution
The implementation of a diffusion board with trenches that achieve total reflection of incident light at specific angles, reducing color mixing between adjacent pixels and minimizing the visibility of black matrices, thereby enhancing image quality and preventing color separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If pixels are expanded with lenses to make black matrix unremarkable, then the black matrix becomes less visible, but execution cost increases due to requiring many lenses
Solution Approach 1:
A diffusion board is introduced as an intermediary component between the display and the lens sheet. This diffusion board scatters light from the pixels before it reaches the lenticular lens, effectively reducing the visibility of black matrices without requiring additional lenses for each pixel, thus lowering execution cost while achieving the desired visual effect
2Object-affected harmful factors
If diffusion board is installed between display and lenticular lens to reduce color mixing, then color separation is reduced, but stereoscopic vision becomes blotted
Solution Approach 1:
The diffusion board is designed with specific local properties: it has a diffusion coefficient and thickness carefully controlled to achieve the right balance. The diffusion board scatters light locally at the pixel level to prevent color mixing between adjacent pixels while maintaining enough directional light transmission to preserve stereoscopic vision quality
3Adaptability or versatility
If lenticular lens is used to achieve stereoscopic effect, then binocular vision is enabled, but black matrix between pixels becomes visible and color separation occurs
Solution Approach 1:
The diffusion board performs a preliminary action by scattering light from the display before the light reaches the lenticular lens. This preliminary light scattering prevents the black matrices from being clearly visible and reduces color separation at the lens stage, allowing the lenticular lens to function effectively for stereoscopic vision without these harmful effects
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively reduces color mixing and improves the reproduction of stereoscopic images by ensuring that the black matrix and color separation are minimized, resulting in a clearer and more accurate stereoscopic vision without the blurring caused by pixel color mixing.
Implementation Method 1
a diffusion board with trenches that achieve total reflection of incident light at specific angles
Implementation Method 2
light from the pixels gathers in the position of white circle 1502 by the effect of lens sheet 101, and it becomes a ray which spreads from that point

AI summary
An autostereoscopic display includes a display having a non-luminescence area between two adjacent pixels. Each pixel includes a blue subpixel, a red subpixel, and a green subpixel. A lens sheet including a lot of lenses is configured over the display. A diffusion board is placed between the display and the lens sheet. The diffusion board has a trench disposed over the non-luminescence area between two adjacent pixels.
