Vertical Subpixel LCD Panel Reducing Data Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LCD panels face challenges in reducing the number of data lines while maintaining an aperture ratio, which affects luminance and picture quality.
Innovation Solution
The LCD panel design includes subpixels arranged vertically with gate lines along long sides and data lines along short sides, featuring storage lines that pass through subpixels in the short direction, and common storage lines connected to both ends of the storage lines to ensure redundancy and minimize aperture ratio reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the number of data lines is reduced to lower cost, then manufacturing cost decreases, but the aperture ratio is reduced which degrades luminance and picture quality
Solution Approach 1:
The invention changes the spatial arrangement of subpixels from conventional horizontal grouping to vertical stacking along the data line direction. By arranging red, green, and blue subpixels vertically at each data line intersection, the patent reduces the number of data lines required while maintaining full color coverage and aperture ratio. This dimensional reorganization allows fewer data lines to address the same number of subpixels, directly resolving the contradiction between reducing data line count and maintaining aperture ratio.
2Device complexity
If the number of data lines is reduced, then device complexity decreases, but maintaining resolution becomes more difficult
Solution Approach 1:
The patent resolves the resolution maintenance issue by transitioning from horizontal to vertical subpixel arrangement. Each vertical stack of red, green, and blue subpixels at a data line intersection maintains the full color information required for resolution, while the reduced number of data lines simplifies device complexity. The vertical stacking ensures that each pixel location receives complete color data despite fewer data lines.
Solution Approach 2:
The invention makes each data line universal by enabling it to address multiple subpixel colors vertically at each intersection point. Instead of requiring separate data lines for each color, a single data line can drive red, green, and blue subpixels vertically stacked at its intersection with gate lines, achieving multi-functionality that maintains resolution while reducing overall data line count.
