Non-quadrangular Display Panel Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-quadrangular display panels, the overlapping of clock signal wires and fanout wires results in varying resistance and capacitance due to unpredictable overlap areas, leading to inconsistent signal transmission to pixels.
Innovation Solution
A non-quadrangular display panel design with signal lines disposed on multiple layers, including a switching circuit that ensures uniform spacing and orthogonal crossing of signal lines, with an insulating layer between layers, to maintain consistent overlap areas and signal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clock signal wires and fanout wires are disposed in the peripheral area of a non-quadrangular display panel, then signal transmission to pixels is enabled, but resistance and capacitance vary due to unpredictable overlap areas
Solution Approach 1:
The patent transitions from a conventional quadrangular layout to a circular display panel geometry, fundamentally changing the spatial dimension in which wires are routed. This dimensional change allows the clock signal wires and fanout wires to be arranged in concentric circular patterns, ensuring uniform overlap areas regardless of the specific routing path, thereby resolving the inconsistency in resistance and capacitance values
Solution Approach 2:
The patent modifies the geometric parameters of the display panel from a quadrangular shape to a circular shape. This parameter change enables the wire layout to maintain constant overlap areas between clock signal wires and fanout wires, as the circular symmetry ensures that any two wires crossing in this configuration will have identical overlap geometries, thus standardizing electrical characteristics
2Adaptability or versatility
If the display panel has an arbitrary non-quadrangular shape, then display area flexibility is improved, but wire overlap areas become unpredictable causing varying resistance and capacitance
Solution Approach 1:
The patent applies local quality by creating specific geometric conditions in the peripheral area where wire overlaps occur. By designing the circular display panel with concentric wire arrangements, the patent ensures that the local overlap regions between clock signal wires and fanout wires have uniform properties (same area, same geometry), while the overall display panel maintains the flexibility of non-quadrangular shapes

AI summary
A non-quadrangular display panel includes a plurality of first signal lines disposed in a non-quadrangular display area, wherein the non-quadrangular display area includes a plurality of pixels. A switching circuit is disposed in a peripheral area of the non-quadrangular display panel. The peripheral area is disposed adjacent to the non-quadrangular display area. The switching circuit passes a signal to at least one of the plurality of first signal lines. A plurality of second signal lines is disposed in the peripheral area. At least two adjacent second signal lines are uniformly spaced apart from each other and transmit signals at different times to the switching circuit. A plurality of third signal lines is disposed in the peripheral area orthogonal to the plurality of second signal lines and connected to the switching circuit.
