Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panel pixel arrangements that improve display resolution by using irregular sub-pixel arrangements lead to a complicated peripheral drive circuit structure, increasing the risk of issues like mura problems and requiring numerous data lines and switch elements, which complicates the display effect.
Innovation Solution
A display panel design where sub-pixels in the column direction correspond to different colors, with drive switches connected to the same data line if they correspond to the same color, simplifying the peripheral drive circuit by reducing the number of data lines and switch elements needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If irregular pixel arrangement is used to improve display resolution, then display resolution is improved, but peripheral drive circuit structure becomes complicated
Solution Approach 1:
The invention segments the drive array into multiple drive columns, where each drive column contains drive switches corresponding to the same color. This segmentation allows drive switches of the same color to be connected to the same data line, reducing the number of data lines required in the peripheral drive circuit while maintaining the irregular pixel arrangement for high display resolution.
Solution Approach 2:
The invention extracts and groups drive switches by color, separating them into distinct drive columns. By taking out drive switches of the same color and organizing them together, the patent reduces the complexity of the peripheral drive circuit, as fewer data lines are needed compared to the conventional approach where each drive switch requires a separate data line connection.
2Measurement precision
If irregular pixel arrangement is used to improve display resolution, then display resolution is improved, but number of data lines increases
Solution Approach 1:
The drive array is segmented into drive columns based on color, allowing multiple drive switches of the same color to share a common data line. This segmentation reduces the total number of data lines required, as data lines are reused for drive switches controlling sub-pixels of the same color across different pixel columns.
Solution Approach 2:
Each data line serves multiple functions by being connected to drive switches of the same color across different drive columns. This multi-functionality reduces the total number of data lines needed, as a single data line can control multiple drive switches that all drive sub-pixels of the same color, thereby reducing the quantity of data lines while maintaining high display resolution.
3Measurement precision
If irregular pixel arrangement is used to improve display resolution, then display resolution is improved, but peripheral drive circuit complexity increases
Solution Approach 1:
The peripheral drive circuit is segmented into multiple drive columns, each handling a specific color. This segmentation simplifies the overall circuit complexity by organizing drive switches of the same color together, allowing for more systematic routing and connection of data lines, thereby reducing the complexity of the peripheral drive circuit while maintaining the irregular pixel arrangement.
Solution Approach 2:
The invention merges drive switches of the same color into the same drive column, allowing them to be connected to the same data line. This merging reduces the number of separate connections required in the peripheral drive circuit, simplifying the overall circuit structure and reducing complexity while still achieving high display resolution through the irregular pixel arrangement.
