Stereoscopic Display Color Filter With Segmented Black Stripes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic image display devices face limitations in vertical viewing angle and aperture ratio due to the width of the black matrix, which increases crosstalk and decreases brightness.
Innovation Solution
The implementation of a stereoscopic image display device with a color filter substrate featuring black stripes that include a first and second black pattern spaced apart, allowing for gaps between them, which enhances the vertical viewing angle while minimizing crosstalk and maintaining aperture ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the width of the black matrix is increased to improve stereoscopic image display, then the vertical viewing angle is improved, but the aperture ratio decreases and brightness is reduced
Solution Approach 1:
The black stripe is divided into a first black pattern and a second black pattern that are spaced apart from each other, creating gaps between them. This segmentation allows light to pass through the gaps while maintaining the black stripe's function of defining viewing angle, thereby resolving the contradiction between improving vertical viewing angle and maintaining aperture ratio.
2Object-affected harmful factors
If the width of the black matrix is increased to reduce crosstalk, then front crosstalk is reduced, but the aperture ratio decreases and brightness is reduced
Solution Approach 1:
By segmenting the black stripe into spaced-apart first and second black patterns, the structure maintains sufficient black material to reduce crosstalk while creating gaps that allow light transmission, thus preventing aperture ratio decrease and brightness reduction.
Solution Approach 2:
The black patterns are strategically positioned and spaced to create local gaps where light transmission is needed, while maintaining black material in areas where crosstalk reduction is critical. This local differentiation resolves the contradiction between reducing crosstalk and maintaining aperture ratio.
3Reliability
If the width of the black matrix is increased to improve stereoscopic image display, then the stereoscopic effect is improved, but brightness is reduced
Solution Approach 1:
The segmented black stripe structure with gaps allows light to pass through while maintaining the stereoscopic image display function, thereby improving brightness without sacrificing stereoscopic image quality.
