Irregular Display Panel with Notched Edge for Signal Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels have wide borders due to limitations in manufacturing integrated circuit chips and soldering of flexible circuit boards, leading to uneven signal line loads and reduced screen ratios, which affect display performance.
Innovation Solution
A display panel design featuring an irregularly-shaped edge with notches, where first and second regular signal lines are connected to respective driving circuits, reducing signal line load differences and improving screen ratio by rearranging wirings and placing functional components like cameras and speakers in notches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an irregularly-shaped display panel is designed to increase screen ratio and avoid functional modules, then the screen ratio is improved, but the wiring arrangement becomes denser and signal line load differences increase
Solution Approach 1:
The display panel is divided into a display area and a non-display area, with the non-display area further segmented into first and second non-display areas. This segmentation allows different wiring arrangements in different regions, reducing overall wiring density while maintaining high screen ratio through the irregular-shaped display area.
Solution Approach 2:
Signal lines are routed through multiple dimensions and layers. First signal lines extend along a row direction while second signal lines extend along a column direction, allowing three-dimensional wiring arrangement that reduces planar density and manages signal line loads more effectively.
2Area of stationary object
If an irregularly-shaped display panel is designed to increase screen ratio, then the screen ratio is improved, but signal line load differences increase affecting display performance
Solution Approach 1:
Different regions of the display panel have different wiring configurations. The first non-display area has first signal lines extending along the row direction, while the second non-display area has second signal lines extending along the column direction. This local differentiation allows optimization of signal line loads in each region, reducing overall load differences while maintaining high screen ratio.
3Area of stationary object
If border width is reduced to increase screen ratio, then the screen ratio is improved, but manufacturing complexity increases due to limitations in integrated circuit chip soldering and flexible circuit board connections
Solution Approach 1:
The non-display area is segmented into first and second non-display areas with different wiring orientations. This segmentation allows modular manufacturing approaches, where each region can be manufactured and tested separately before assembly, reducing overall manufacturing complexity despite the irregular shape and narrow borders.
Solution Approach 2:
The signal line configuration is designed to serve multiple functions: first signal lines handle row-direction connections while second signal lines handle column-direction connections. This multi-functional wiring design allows a single panel structure to accommodate different manufacturing techniques and component arrangements, easing manufacturing constraints.
