Display Electrode Connection Layout for Slim Border Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in achieving a slim border design due to the need for efficient layout and assembly of circuitry, particularly in integrating conducting structures without increasing the device's border width.
Innovation Solution
The display device incorporates a conducting structure with a conductive member connected between a conducting pad and an opposite electrode layer, featuring a conducting hole that penetrates through the display layer, allowing for a reduced border width by minimizing the size of the conducting structure within the original device area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a conventional conducting structure is used to connect the driving circuit layer and opposite electrode layer, then electrical connectivity is maintained, but the border width increases and slim border design cannot be achieved
Solution Approach 1:
The conducting structure is repositioned from the border region into the display region, utilizing the display region space for conducting functions. This dimensional relocation allows the border to be narrowed while the conducting structure remains functional within the original device footprint.
Solution Approach 2:
The conducting structure is integrated within the display region rather than being separate in the border area. By merging the conducting function into the display region, the patent eliminates the need for additional border space while maintaining electrical connectivity between layers.
2Length of moving object
If the conducting structure size is reduced to achieve slim border, then border width decreases, but manufacturing precision and assembly difficulty increase
Solution Approach 1:
The conducting structure is merged with the display region components, allowing it to be positioned and manufactured alongside other display elements using the same precision standards. This integration reduces the need for separate high-precision positioning in the border region.
3Length of moving object
If the conducting structure is integrated into the display region, then border width is reduced, but the layout complexity of the circuit increases
Solution Approach 1:
The display region is segmented into functional zones, with the conducting structure placed in a specific segment that does not interfere with the active display area. This segmentation allows the conducting structure to be integrated without complicating the overall circuit layout.
Solution Approach 2:
The conducting structure is arranged in a different spatial dimension or orientation within the display region, allowing it to coexist with other circuit elements without increasing layout complexity. The conducting structure utilizes unused space in the display region rather than adding to the circuit path length.
