Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display (LCD) apparatuses face challenges in maximizing the opening ratio, which affects light transmittance and luminance due to the design of the substrate and electrode structures.
Innovation Solution
The display apparatus incorporates capsular structures with cavities, a common electrode, and color filters, along with a light blocking pattern, to enhance the opening ratio by optimizing the arrangement of sub pixel regions and electrodes, and using materials like opaque organic material or metal for the light blocking pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional substrate and electrode structures are used, then device complexity is reduced, but opening ratio is limited
Solution Approach 1:
The display panel is divided into multiple sub-pixel regions (red, green, blue) within each pixel region, allowing independent optimization of each sub-region. This segmentation enables better utilization of space and improved opening ratio while maintaining manageable structural complexity through modular design
Solution Approach 2:
The patent introduces a vertical dimension by forming capsular structures that extend upward from the substrate surface. This three-dimensional configuration allows the common electrode to be positioned above the pixel electrodes, creating additional spatial freedom for optimizing light paths and improving opening ratio without increasing planar complexity
2Illumination intensity
If opening ratio is increased, then light transmittance and luminance are improved, but device complexity increases
Solution Approach 1:
The common electrode is nested within the capsular structures, which themselves are positioned within the pixel regions. This nested arrangement allows multiple functional elements to occupy the same spatial volume, improving light transmittance while managing complexity through hierarchical organization
Solution Approach 2:
Different regions of the display panel have different configurations - each sub-pixel region has optimized electrode arrangements and capsular structure positions tailored to its specific color requirements. This local optimization improves overall luminance while containing complexity to specific functional zones rather than requiring complex solutions across the entire display
