Display Panel Notch Sealing for Compact Waterproof Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels have a significant non-display area that reduces the effective display area, and existing designs struggle to minimize this area while maintaining water-proofing and structural integrity.
Innovation Solution
The display panel incorporates a notch portion that recedes from the side of the display panel, allowing the sealing member to contact the window cover through the notch, which enables the position of the sealing member and bending portion to be shifted towards the display area, thereby reducing the non-display area while maintaining water-proofing characteristics. This design includes specific wiring configurations and a dual-wiring structure for power transfer, and the use of a mesh power wiring to ensure efficient power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the peripheral area is reduced to increase the display area, then the effective display area is improved, but the water-proofing and structural integrity are compromised
Solution Approach 1:
The sealing member is configured to extend from the peripheral area through a notch portion into the display area, utilizing the depth dimension to achieve water-proofing while minimizing the lateral peripheral area. This allows the sealing function to be achieved in a different spatial arrangement that reduces the non-display area.
Solution Approach 2:
The notch portion is formed within the peripheral area, creating a nested structure where the sealing member can pass through the peripheral region into the display area. This nested configuration allows the sealing function to be integrated within the existing structure without requiring additional peripheral space.
2Area of stationary object
If the peripheral area is reduced to increase the display area, then the effective display area is improved, but the structural integrity is compromised
Solution Approach 1:
The bending portion extends from the peripheral area through the notch into the display area, utilizing the depth dimension to maintain structural support while reducing the lateral peripheral area. This three-dimensional configuration provides structural reinforcement without occupying additional planar space.
Solution Approach 2:
The bending portion is nested within the peripheral area structure, creating a multi-layered configuration that reinforces the display panel's structural integrity. This nested arrangement allows structural support elements to be integrated within the existing peripheral framework.
3Area of stationary object
If the sealing member position is shifted towards the display area to reduce non-display area, then the effective display area is improved, but the water-proofing complexity increases
Solution Approach 1:
The sealing member serves multiple functions: it provides water-proofing, structural support through the bending portion, and defines the notch portion geometry. This multi-functionality reduces the need for separate components, simplifying the overall structure despite the shifted position.
Solution Approach 2:
The sealing member and bending portion are merged into a single integrated component that performs both sealing and structural functions. This combination reduces the number of discrete parts and simplifies the assembly process, offsetting the increased complexity from the repositioned sealing structure.
4Area of stationary object
If the wiring configuration is optimized to accommodate the notch structure, then the space utilization is improved, but the manufacturing complexity increases
Solution Approach 1:
The wiring structure is segmented into multiple layers and routed through the notch portion, with power transfer wirings and signal transfer wirings separated into different spatial zones. This segmentation allows each wiring type to be optimized independently for space efficiency while maintaining manufacturability through systematic routing.
Solution Approach 2:
The wiring configuration utilizes vertical layering and three-dimensional routing through the notch portion, moving from a two-dimensional planar arrangement to a three-dimensional spatial configuration. This enables more efficient space utilization by routing wirings through the depth dimension rather than requiring additional lateral space.
