Non-Rectangular Display Device Narrow Frame Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display apparatuses with non-rectangular displaying regions, the arrangement of drivers and wiring lines in the frame region becomes complex, making it difficult to achieve a narrow frame construction.
Innovation Solution
The display apparatus features gate drivers and source drivers positioned opposite each other with the displaying region in between, using gate connection lines that intersect the displaying region to connect gate lines to drivers, allowing for a more efficient routing of wiring lines and reducing the complexity of the frame region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If drivers are arranged in the frame region along the edges of a non-rectangular displaying region, then the wiring lines can be routed to connect drivers to displaying regions, but the frame region becomes wide and complex routing is required
Solution Approach 1:
The patent applies dimensionality change by routing gate connection lines not only along the edge direction but also in a direction intersecting the first direction (perpendicular or oblique routing). This allows gate connection lines to reach gate drivers positioned in the frame region more efficiently, reducing the required frame region width while maintaining manufacturability. The wiring lines utilize two-dimensional space in the frame region rather than being constrained to one-dimensional edge routing.
Solution Approach 2:
The patent employs asymmetric arrangement where gate drivers are positioned at specific locations in the frame region (e.g., at corners or along specific edges) rather than symmetrically distributed. The gate connection lines are routed asymmetrically to connect gate lines from different sides of the displaying region to the gate drivers, optimizing the use of frame region space and reducing overall frame width.
2Area of stationary object
If gate drivers and source drivers are positioned on the same side of the displaying region, then the frame region can be narrowed on three sides, but wiring line routing becomes complex
Solution Approach 1:
The patent segments the driver arrangement by positioning gate drivers and source drivers at different locations in the frame region (opposite sides or adjacent sides). This segmentation allows wiring lines to be routed separately to each driver type, simplifying the overall routing complexity. Gate connection lines and source connection lines can be independently optimized without interfering with each other, reducing the complexity of wiring line routing while maintaining narrow frame width.
3Area of moving object
If the frame region is narrowed to achieve three-side narrow frame type, then the displaying region area increases, but the arrangement of drivers and wiring lines becomes more complex
Solution Approach 1:
The patent utilizes dimensional flexibility in the frame region by allowing gate connection lines to extend in directions intersecting the first direction. This enables efficient connection of gate drivers to displaying regions on multiple sides without requiring additional frame width, thus increasing displaying region area while managing driver arrangement complexity through spatial optimization.

AI summary
A display apparatus (100) having a displaying region (RD) of a non-rectangular shape includes: a plurality of gate lines (22) being disposed in the displaying region (RD) and extending along a first direction; a plurality of source lines (24) extending along a second direction; a plurality of gate drivers (20G) and a plurality of source drivers (20S) disposed in the frame region (RF); and a gate connection line (26) being provided in the displaying region (RD) so as to extend along a direction which intersects the first direction and connected to one of the gate drivers (20G) and one of the plurality of gate lines (22). A region in which the plurality of gate drivers (20G) are provided and a region in which the plurality of source drivers (20S) are provided are opposite from each other, with the displaying region (RD) being interposed therebetween.
