Display Panel Signal Terminal Matrix for Narrow Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels have large frames due to the need for elongated connection lines to achieve electrical insulation between signal lines, which increases the size of the non-display region and the overall display device.
Innovation Solution
The display panel design includes alternately and separately arranged touch and display signal terminals on the driver chip, increasing the distance between edge signal terminals to reduce the length of connection lines required for insulation, thereby minimizing the non-display region and frame size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If connection lines are arranged adjacently to connect signal lines to signal terminals, then the number of connection lines is reduced, but the length of each connection line must be elongated to achieve electrical insulation between adjacent connection lines
Solution Approach 1:
The patent transitions from a one-dimensional linear arrangement of signal terminals to a two-dimensional matrix arrangement. Signal terminals are organized in multiple rows and columns, allowing connection lines to connect to terminals in different spatial dimensions. This dimensional change enables connection lines to be shorter while still achieving proper spacing for electrical insulation, as terminals can be positioned in adjacent columns rather than requiring elongated paths in a single row.
Solution Approach 2:
The patent segments the signal terminals into multiple groups arranged in a matrix structure, with different types of signal terminals (data, clock, control) distributed across different rows and columns. This segmentation allows connection lines to connect to specific terminal groups more directly, reducing the overall length required while maintaining electrical insulation between adjacent connection lines through proper spatial distribution.
2Reliability
If connection lines are elongated to achieve electrical insulation, then insulation between connection lines is ensured, but the non-display region becomes larger
Solution Approach 1:
By organizing signal terminals in a two-dimensional matrix with multiple rows and columns, the patent enables connection lines to achieve electrical insulation by utilizing spatial separation in both horizontal and vertical dimensions. This allows connection lines to be shorter while still maintaining adequate spacing, thereby reducing the non-display region area while ensuring reliable electrical insulation.
Solution Approach 2:
The patent changes the spatial arrangement parameters of signal terminals from a linear configuration to a matrix configuration with specific row and column distributions. This parameter change optimizes the spacing between connection lines, ensuring electrical insulation is achieved with shorter connection line lengths, thus reducing the overall non-display region area.
3Ease of manufacture
If signal terminals of the same type are arranged adjacently, then the arrangement is simplified, but the distance between edge signal terminals is reduced requiring longer connection lines
Solution Approach 1:
The patent segments signal terminals of the same type into different rows and columns within the matrix arrangement. Instead of clustering all terminals of one type together in a single row, they are distributed across multiple locations. This segmentation increases the distance between edge terminals of the same type, allowing connection lines to be optimized in length while maintaining manufacturing simplicity through the regular matrix structure.
Solution Approach 2:
The patent uses the two-dimensional matrix structure to distribute signal terminals of the same type across different rows and columns. This dimensional distribution increases the spatial distance between edge terminals of the same type, enabling shorter connection lines to be used while maintaining the organized and manufacturable arrangement characteristic of matrix structures.
