Hexagonal Pixel Unit Sharing Data Lines to Reduce Wiring Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panels have a low effective aperture ratio and light transmittance due to the rectangular design and spacing of signal lines, which increases power consumption and reduces the service life.
Innovation Solution
A pixel unit with a hexagonal structure where at least two sub-pixel units share a data line and gate lines are arranged in parallel, reducing the wiring area and increasing the aperture ratio, thereby enhancing light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rectangular design with separate data lines for each sub-pixel is used, then each sub-pixel can be independently controlled, but the wiring area increases and the aperture ratio decreases
Solution Approach 1:
The patent merges data line resources by having multiple sub-pixels share common data lines. Specifically, in the hexagonal pixel unit, data lines are shared among adjacent sub-pixels, reducing the total number of data lines needed and thereby reducing the wiring area while maintaining independent control capability through the shared line structure
Solution Approach 2:
The shared data lines serve multiple sub-pixels simultaneously, making the data lines universal rather than dedicated to single sub-pixels. This multi-functionality allows the same data line to carry signals for multiple sub-pixels, reducing the overall wiring area while preserving control independence
2Object-affected harmful factors
If space is set between signal lines and pixel electrodes to reduce signal interference, then signal interference is reduced, but the aperture ratio and light transmittance decrease
Solution Approach 1:
By merging data lines into shared lines that serve multiple sub-pixels, the patent reduces the total wiring area occupied by signal lines. This reduction in wiring area eliminates the need for large spacing between signal lines and pixel electrodes, thereby increasing the aperture ratio and light transmittance while maintaining adequate signal isolation through the shared line architecture
3Measurement precision
If more data lines are used for each sub-pixel, then signal control precision is improved, but the aperture ratio and power consumption increase
Solution Approach 1:
The patent achieves signal control precision through the shared data line structure rather than through dedicated lines for each sub-pixel. The shared data lines are strategically positioned and routed to provide precise control signals to multiple sub-pixels, maintaining control precision while reducing the overall wiring area and increasing the aperture ratio
