Display Panel Fan-Out Jumper Layout for Signal Order Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face signal transmission disorders and poor display due to fan-out wires not being able to connect to corresponding output terminals, resulting in potential short circuits and inconsistent ordering.
Innovation Solution
The display panel employs a wire-changing jumper design with fan-out wires comprising first and second sections connected on different layers, ensuring each fan-out wire connects to a corresponding output terminal without short circuits, maintaining consistent ordering and preventing signal disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If fan-out wires are connected to output terminals in a middle area of the driving chip, then the bonding area can be moved up to achieve a narrow frame, but the fan-out wires cannot be electrically connected to corresponding output terminals, resulting in signal transmission disorder
Solution Approach 1:
The fan-out wires are divided into two layers: first fan-out sections in a first layer and second fan-out sections in a second layer. This multi-layer arrangement allows the wires to connect to corresponding output terminals without short circuits, resolving the signal transmission disorder while maintaining the narrow frame design
Solution Approach 2:
Each fan-out wire is segmented into multiple sections (first fan-out sections and second fan-out sections) located in different layers. This segmentation enables proper electrical connection between fan-out wires and output terminals, solving the signal transmission problem
2Reliability
If fan-out wires are arranged to connect to output terminals, then signal transmission can be achieved, but short circuits may occur between adjacent fan-out wires
Solution Approach 1:
By placing first fan-out sections in a first layer and second fan-out sections in a second layer, the patent creates vertical separation between wire segments. This multi-dimensional arrangement prevents short circuits between adjacent fan-out wires while enabling proper connection to output terminals

AI summary
The present disclosure discloses a display panel and a display device. The display panel comprises a driving chip and fan-out wires. Fan-out wires in a first fan-out wire group are electrically connected to corresponding output terminals through a second side of an adjacent driving chip; each of the fan-out wires in the first fan-out wire group comprises a first fan-out section and a second fan-out section that are connected and located on different layers. The present disclosure adopts a wire-changing jumper design to prevent signal disorder caused by inconsistent orders of the output terminals and the fan-out wires.
