Display Panel Electrode Layout for Higher Pixel Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel technologies are limited in improving resolution due to structural constraints, which restrict the number of pixels and hence the clarity of the screen.
Innovation Solution
The display panel design includes a first substrate with scan lines and data lines, where the second sub-portions are arranged between adjacent data lines, and a second transparent conductive layer forming pixel electrodes, along with a semiconductor layer and a black matrix to increase pixel density and aperture, allowing for a higher resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of pixels in the display panel is increased to improve resolution, then the clarity of the screen is improved, but the existing panel structure limits the ability to effectively increase pixel density
Solution Approach 1:
The first metal layer is divided into multiple first metal portions, where each first metal portion includes multiple second sub-portions arranged along the second direction. This segmentation allows for increased pixel density while maintaining manageable structural complexity, as each sub-portion can be independently formed and controlled during manufacturing.
Solution Approach 2:
The patent introduces a vertical stacking dimension by placing the first metal layer, second metal layer, and transparent conductive layer at different heights. The first metal portions extend in both first direction (parallel to scan lines) and second direction (parallel to data lines), creating a three-dimensional electrode structure that increases pixel density without proportionally increasing planar complexity.
2Quantity of substance
If data lines are arranged to support higher pixel density, then more pixels can be accommodated, but the width and spacing of data lines must be precisely controlled
Solution Approach 1:
The patent specifies that the width of data lines ranges from 1.5 micrometers to 3 micrometers, and defines precise spacing relationships where one second sub-portion is disposed between two adjacent data lines. These parameter specifications provide clear manufacturing targets that balance high pixel density with achievable fabrication precision using conventional semiconductor manufacturing processes.
3Illumination intensity
If the aperture ratio is maintained or enhanced while increasing pixel density, then light transmission efficiency is preserved, but the arrangement of conductive layers and electrodes becomes more complex
Solution Approach 1:
The first metal portions serve multiple functions: they form part of the storage capacitor structure, provide electrical connection between scan lines and pixel electrodes, and define pixel boundaries. The transparent conductive layer simultaneously forms pixel electrodes and maintains electrical continuity. This multi-functionality reduces the need for additional dedicated structures, thereby maintaining aperture ratio while achieving high pixel density.
Solution Approach 2:
By stacking the first metal layer, second metal layer, and transparent conductive layer vertically, the patent creates a three-dimensional electrode architecture. The first metal portions extend in both first direction (parallel to scan lines) and second direction (parallel to data lines), allowing efficient space utilization that maintains large aperture ratios while supporting high pixel density without requiring excessive planar complexity.
