LCD Super-Pixel Layout for Adjustable White Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid-crystal display (LCD) devices face challenges in adjusting the area occupied by pixels emitting white light, which limits their ability to optimize transmittance and contrast ratio without reducing power consumption.
Innovation Solution
The LCD device employs a novel layout of super-pixels arranged in intersecting directions, with specific connections and orientations of data and gate lines, allowing for adjustable area allocation to white pixels while maintaining equal contributions from red, green, and blue pixels, enabling independent adjustment of the white pixel area without affecting transmittance or power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all pixels are arranged in a matrix, then the display structure is simple and regular, but the area occupied by white pixels cannot be adjusted
Solution Approach 1:
The display is divided into super-pixels, each containing multiple individual pixels (red, green, blue, and white). This segmentation allows independent control and area adjustment of white pixels within each super-pixel while maintaining an overall regular matrix structure, resolving the contradiction between adjustability and complexity.
Solution Approach 2:
Multiple pixels (red, green, blue, and white) are merged into a single super-pixel unit. This merging enables the white pixel area to be adjusted independently within the super-pixel framework without disrupting the overall matrix arrangement, achieving both adaptability and structural simplicity.
2Illumination intensity
If the area of white pixels is increased, then transmittance and contrast ratio are improved, but power consumption increases
Solution Approach 1:
The patent enables dynamic adjustment of the white pixel area ratio within super-pixels. By making the white pixel area adjustable rather than fixed, the system can optimize the balance between transmittance/contrast ratio and power consumption based on different display conditions and requirements.
Solution Approach 2:
The invention changes the parameter of white pixel area ratio within super-pixels to optimize performance. By adjusting this parameter, the system can improve transmittance and contrast ratio while controlling power consumption, as the white pixel area can be optimized rather than maximized.
3Illumination intensity
If the area of white pixels is adjusted, then transmittance and contrast ratio can be optimized, but the layout becomes more complex
Solution Approach 1:
By segmenting the display into super-pixels with standardized internal structures, the patent simplifies the overall layout while enabling flexible adjustment of white pixel area within each segment. This segmentation approach maintains regularity at the macro level while providing adjustability at the micro level.
Solution Approach 2:
The super-pixel structure serves multiple functions: it maintains the regular matrix layout, enables independent white pixel area adjustment, and provides a framework for optimizing transmittance and contrast ratio. This multi-functionality reduces the need for separate mechanisms for each purpose.
