Display Device Data Signal Links for Thin Edge Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with high-resolution panels require a significant peripheral region to accommodate numerous conducting lines, leading to a wide edge that contradicts the demand for a thin edge design in modern electronic devices.
Innovation Solution
The display device incorporates data signal links within the display region to electrically connect the source driver and data lines, eliminating the need for external conducting lines in the peripheral region, and utilizes extension lines and rearranged data signal links to equalize the loading effect and maintain display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the peripheral region is increased to accommodate numerous conducting lines for high-resolution panels, then the electrical connection between chip driver and pixels is improved, but the edge width of the display device becomes wider
Solution Approach 1:
The patent transitions the data signal transmission from the peripheral region (2D plane around display region) to the display region itself by utilizing data signal links formed within the display area. This dimensional repositioning allows conducting lines to be integrated into the active display area rather than occupying peripheral space, thereby reducing edge width while maintaining electrical connection reliability.
Solution Approach 2:
The patent merges the data signal transmission function with the display region by forming data signal links within the display area. The data signal links are integrated with the pixel structure, combining the functions of signal transmission and display operation in the same spatial region, thus eliminating the need for separate peripheral conducting lines.
2Reliability
If external conducting lines are disposed in the peripheral region to deliver data signals, then the data signal transmission is ensured, but the edge area of the display device is increased
Solution Approach 1:
The patent extracts the data signal transmission function from the peripheral region and relocates it to the display region. By taking out the external conducting lines from the peripheral area and replacing them with data signal links formed within the display area, the invention eliminates the need for wide edges while preserving data signal transmission capability.
Solution Approach 2:
The data signal links serve multiple functions: they transmit data signals from the source driver to the data lines, and they are integrated within the display region structure. This multi-functionality allows the same spatial region to serve both display and signal transmission purposes, reducing the overall device edge area.
Data Source
AI summary
A display device includes a substrate, gate lines, data lines, data signal links, and contact vias. The substrate includes a display region, and a peripheral region surrounding the display region. The gate lines, data lines, data signal links, and contact vias are disposed within the display region of the substrate. The gate lines cross the data lines. Each of the data signal links is disposed between adjacent gate lines. Each of the contact vias is disposed between each of the data signal links and a corresponding data line, such that each of the data signal links is electrically connected with the corresponding data line.
