Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D displays face issues with image crosstalk and color shifting due to reduced pixel size, which deteriorate the 3D display quality, and increasing the black matrix width to mitigate these issues decreases the aperture ratio.
Innovation Solution
A 3D display apparatus with alternating first and second pixel row pairs and a pattern retarder film, where sub-pixels are arranged in a matrix manner, and partial regions of pixel rows are turned off to form a shading black matrix between pixel row pairs, enhancing the aperture ratio and reducing image crosstalk and color shifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pixel size is reduced to improve definition, then the resolution is improved, but image crosstalk increases and 3D display quality deteriorates
Solution Approach 1:
The pixel rows are divided into alternating first pixel row pairs and second pixel row pairs, with each pair containing specific sub-pixel arrangements. This segmentation allows different regions to serve different functions: some regions display images while others form black matrix regions, thereby reducing image crosstalk while maintaining high definition through the alternating pattern structure
Solution Approach 2:
Different regions within the display panel are assigned different functions: first sub-pixels and second sub-pixels in odd/even rows have different configurations, with some regions turned off to form black matrix. This local differentiation allows the display to achieve both high definition in active regions and effective crosstalk reduction in black matrix regions simultaneously
2Object-affected harmful factors
If the width of black matrix is increased to reduce image crosstalk, then image crosstalk is mitigated, but aperture ratio decreases
Solution Approach 1:
The black matrix function is achieved not by increasing width in one dimension but by utilizing the row-pair dimension. Alternating first and second pixel row pairs create horizontal black matrix regions without requiring increased vertical black matrix width, thus reducing crosstalk while preserving aperture ratio
Solution Approach 2:
Only partial regions of pixel rows are turned off to form black matrix, rather than increasing the black matrix width across the entire display. This partial action achieves the necessary crosstalk reduction while minimizing the impact on aperture ratio by keeping other regions fully active
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
The solution effectively reduces image crosstalk, maintains high definition, and enhances the aperture ratio by arranging sub-pixels in an alternating manner and turning off partial regions to create a shading black matrix, thereby mitigating color shifting issues.
Implementation Method 1
When the light of the display passes through the quarter-wave phase retarders with different orientations, the light is transformed into a left handed circularly polarized light and a right handed circularly polarized light, respectively
Implementation Method 2
A user can use circular polarizer glasses with different polarized directions such that the user's left eye only sees images of the left image pixels, and the user's right eye only sees images of the right image pixels
