Display Pixel Layout With Zigzag Columns for Higher Aperture Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is an increasing demand for display apparatuses capable of displaying high-quality images, but existing technologies do not adequately address the need for improved visibility and aperture ratio in pixel arrangements.
Innovation Solution
A display apparatus with a unique pixel arrangement where first and third pixels form zigzag patterns in alternating columns, and second and fourth pixels form straight-line patterns in alternating rows, enhancing visibility and maintaining an excellent aperture ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pixels are arranged in a conventional grid pattern, then the manufacturing process is simple, but the visibility and aperture ratio are insufficient
Solution Approach 1:
The patent applies asymmetry by arranging pixels in non-uniform patterns where columns have different configurations. Specifically, odd-numbered columns have pixels at different positions compared to even-numbered columns, creating an asymmetric overall arrangement that optimizes aperture ratio while maintaining manufacturing feasibility through systematic variation rather than complete irregularity
Solution Approach 2:
The patent transitions from a simple two-dimensional grid to a more complex spatial arrangement by introducing vertical offset variations between adjacent columns. This dimensional variation allows pixels to be positioned at different heights in alternating columns, effectively utilizing three-dimensional space within the display plane to improve aperture ratio without compromising manufacturing simplicity
2Illumination intensity
If pixels are arranged to maximize aperture ratio, then visibility improves, but the manufacturing process becomes more complex
Solution Approach 1:
The patent segments the pixel array into distinct column groups with different arrangement patterns. By dividing the display into alternating column types (odd columns with one pattern, even columns with another), the complex high-aperture arrangement is broken down into repeatable modular units that can be manufactured using standardized processes applied iteratively across the display
3Manufacturing precision
If a zigzag pixel arrangement is used, then visibility and aperture ratio are enhanced, but the structural symmetry is reduced
Solution Approach 1:
The patent implements periodic action by repeating the zigzag column pattern at regular intervals throughout the display. The alternating column configurations (odd/even column patterns) are systematically repeated across the entire pixel array, creating a periodic structure that maintains overall compositional stability and symmetry at the macro level while achieving enhanced aperture ratio at the micro level
