Display Panel Connecting Line for Narrow Frame Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panel designs face challenges in achieving a narrow frame due to the need for fan-out lines that occupy significant space, particularly at the lower borders, which hinders the miniaturization of display devices and user experience.
Innovation Solution
The display panel incorporates a connecting line that electrically connects data lines in a second display area to fan-out lines in a first fan-out area, allowing the fan-out lines to be routed away from the borders, thereby reducing the frame width and enabling a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If fan-out lines are routed along the borders of the display area, then electrical connection between data lines and fan-out lines is achieved, but the frame width of the display panel increases
Solution Approach 1:
The connecting line transitions from a two-dimensional planar routing along the border to a three-dimensional structure by overlapping with data lines in the thickness direction. This vertical arrangement allows the connecting line to carry signals for multiple data lines simultaneously, reducing the horizontal space required and thereby narrowing the frame width.
Solution Approach 2:
The connecting line serves multiple functions: it electrically connects fan-out lines to multiple different data lines (first, second, and third data lines) and can be shared by multiple data lines. This multi-functionality reduces the total number of separate connection paths needed, simplifying the routing structure and reducing frame width.
2Length of stationary object
If fan-out lines are routed away from the borders through connecting lines, then frame width is reduced, but the electrical connection path becomes more complex
Solution Approach 1:
Multiple connection functions are merged into a single connecting line structure. The connecting line simultaneously connects to multiple data lines (first, second, third data lines) and carries their signals to the fan-out lines, consolidating what would otherwise require multiple separate connection structures and reducing overall complexity.
Solution Approach 2:
The connection structure moves from horizontal separation to vertical overlapping in the thickness direction. This three-dimensional arrangement allows multiple data lines to share a common connecting line without requiring complex horizontal routing, simplifying the overall connection structure while reducing frame width.
3Length of stationary object
If multiple data lines share a common connecting line, then frame width is further reduced, but signal interference may increase
Solution Approach 1:
By arranging the connecting line to overlap with data lines in the thickness direction rather than running parallel to them in the same plane, the patent reduces capacitive coupling and electromagnetic interference between the connecting line and data lines, minimizing signal interference while enabling multiple data lines to share the common connecting line.
