Display Assembly Antenna Substrate for Flexible RF Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently mounting next-generation communication antennas, particularly in ultra-high frequency bands, due to space constraints and environmental influences, which affect performance.
Innovation Solution
A display assembly is designed with an integrated antenna structure that extends from the display panel's substrate, allowing flexible mounting and orientation of communication devices, including a first area on the display panel and a second area extending beyond its boundaries, accommodating various circuit parts and securing mounting space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the circuit board is enlarged to mount communication devices, then the mounting space is increased, but the device size and integration density are worsened
Solution Approach 1:
The patent extends the substrate into a second area that protrudes from the display panel in a direction perpendicular to the display surface, utilizing three-dimensional space rather than expanding the two-dimensional circuit board area. This allows mounting communication devices vertically or at angles, resolving the contradiction between mounting space and device volume.
Solution Approach 2:
The communication device is mounted on the extended substrate area that overlaps with the housing space, effectively nesting the communication device within the existing device envelope rather than requiring additional external space. This nesting approach increases mounting capability without proportionally increasing overall device volume.
2Productivity
If communication devices are stacked one over another to save space, then the mounting density is improved, but the antenna performance and signal quality are worsened due to environmental influences
Solution Approach 1:
Instead of stacking communication devices vertically (one over another), the patent extends the substrate horizontally in a second area that protrudes from the display panel. This spatial redistribution places communication devices in different locations with better environmental conditions for antenna operation, maintaining mounting density while improving signal quality.
Solution Approach 2:
The patent creates a localized extended substrate area specifically optimized for mounting communication devices with favorable environmental conditions. This localized approach ensures that antenna-critical components are positioned in areas with appropriate clearance from interfering structures, rather than uniformly stacking all components.
3Adaptability or versatility
If a separate board structure is added for antenna mounting, then the antenna placement flexibility is improved, but the device complexity and manufacturing difficulty are worsened
Solution Approach 1:
The patent merges the antenna mounting substrate with the display panel substrate, creating an integrated structure rather than adding a separate board. The substrate serves dual functions as both the display panel support and the antenna mounting platform, reducing component count and simplifying manufacturing while maintaining placement flexibility.
Solution Approach 2:
The substrate is designed with multi-functionality, serving as both the display panel substrate and the antenna mounting board. The extended second area of the substrate provides universal mounting capability for various communication devices and antenna configurations without requiring additional specialized structures.
4Area of stationary object
If the substrate area is extended beyond the display panel boundaries, then the mounting space for communication devices is improved, but the display assembly complexity is worsened
Solution Approach 1:
The extended substrate area is integrated with the housing structure through overlapping and securing mechanisms, merging multiple functions into a unified assembly. This integration approach manages the increased complexity by coordinating the substrate extension with existing housing and mounting structures rather than creating entirely separate systems.
