Pixel Array Asymmetry and Buffering for 3D Display Crosstalk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional display technologies, particularly in mobile handheld devices, suffer from reduced image resolution and large pitch between sub-pixels in landscape mode, leading to defects like crosstalk due to the conventional arrangement of sub-pixels with a horizontal length less than the vertical length, which limits the viewing angle and image quality.
Innovation Solution
A pixel array is designed with sub-pixels arranged in a specific pattern where each row includes repeating units of three different colors, and each column has sub-pixels of varying colors, allowing for a shift in the sub-pixels along the row or column direction, reducing the horizontal length of sub-pixels while maintaining or exceeding the vertical height, and incorporating buffer pixels displaying black to reduce crosstalk and enhance viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sub-pixels are arranged with horizontal length less than vertical length in conventional pattern, then vertical resolution is maintained, but horizontal resolution is reduced and pitch between sub-pixels increases
Solution Approach 1:
The patent applies asymmetry by designing sub-pixels with different dimensions in horizontal and vertical directions, specifically making the horizontal length greater than or equal to the vertical length, which reverses the conventional orientation and optimizes the pixel arrangement for landscape mode display to improve horizontal resolution
Solution Approach 2:
The patent introduces a shifted arrangement pattern where sub-pixels in adjacent columns are displaced vertically relative to each other, creating a staggered grid structure that effectively increases the number of sub-pixels along the row direction without increasing the physical display area
2Manufacturing precision
If sub-pixels are densely arranged to improve horizontal resolution, then more sub-pixels fit in row direction, but crosstalk between left and right eye images increases
Solution Approach 1:
The patent segments the display area into alternating visible regions for left and right eyes, with buffer pixels inserted between them to create clear separation zones, preventing light from one eye's image from interfering with the other eye's image
Solution Approach 2:
The patent introduces buffer pixels as intermediary elements between the left-eye and right-eye visible regions. These buffer pixels display black color and act as optical barriers that block light leakage, thereby eliminating crosstalk while maintaining the high-density sub-pixel arrangement
3Object-generated harmful factors
If buffer pixels are inserted to reduce crosstalk, then crosstalk is reduced and viewing angle is improved, but the number of effective image-displaying sub-pixels decreases
Solution Approach 1:
The patent applies partial action by inserting buffer pixels at specific intervals (every M sub-pixels) rather than continuously throughout the display. This selective placement provides sufficient crosstalk reduction and viewing angle improvement while minimizing the loss of effective image-displaying sub-pixels
