Display Device Bezel Reduction via Internal Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have an increased bezel area due to the external exposure of signal lines, which affects the aesthetic appeal and assembly accuracy of multi-display devices when multiple units are tiled together.
Innovation Solution
Incorporating guide protrusions and a panel support frame that allows for the internal routing of signal lines and the use of guide members to connect display devices, reducing the bezel area and improving assembly accuracy by guiding the attachment of protective and side cover films.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If signal lines are externally exposed and surrounded by front case, then signal lines are protected and connected, but bezel area is increased
Solution Approach 1:
The patent extracts the signal lines from the external exposed position and routes them internally through the panel support frame. The signal lines are concealed within the frame structure, eliminating the need for a large front case bezel while maintaining protection and connectivity. This extraction principle directly reduces the bezel area while preserving the functional integrity of the signal transmission path.
Solution Approach 2:
The patent transitions the signal line routing from a two-dimensional external surface path to a three-dimensional internal pathway through the panel support frame. By utilizing the vertical and depth dimensions of the frame structure, the signal lines are routed internally without increasing the front bezel area, thereby reducing the visible bezel while maintaining connection integrity.
2Area of stationary object
If front case surrounds signal pad and driving circuit, then components are protected, but bezel area is increased
Solution Approach 1:
The patent merges the protective function previously performed by the separate front case with the panel support frame itself. The frame structure is designed to simultaneously provide mechanical support for the display panel and internal routing pathways for signal lines, eliminating the need for a separate front case component. This integration reduces the bezel area while maintaining protection of internal components.
Solution Approach 2:
The panel support frame is designed with multi-functionality, serving both as a structural support element and as a conduit for signal line routing. By making the frame universal in its functions, the patent eliminates the need for additional protective casing components, thereby reducing the overall bezel area while maintaining component protection and signal connectivity.
3Manufacturing precision
If guide protrusions are inserted in panel support frame, then assembly accuracy is improved, but device complexity is increased
Solution Approach 1:
The guide protrusions are pre-formed as integral features of the panel support frame during frame manufacturing. This preliminary action ensures that the guide structures are already in place before assembly, providing automatic alignment guidance for the cover shield and side cover film without requiring additional assembly steps or complex adjustment mechanisms. The guide features are built-in rather than added, minimizing the increase in device complexity.
Solution Approach 2:
The guide protrusions enable the cover shield and side cover film to self-align and self-position during assembly. The protrusions automatically guide the components into the correct positions without requiring external alignment tools or complex positioning mechanisms. This self-service capability improves assembly accuracy while keeping the added structural complexity minimal, as the guide features simply provide passive geometric constraints.
