Display Bezel Antenna Integration for Space-Limited Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face space constraints due to the presence of additional components such as cover glass, display, and printed circuit boards, which hinder the disposition of antenna structures.
Innovation Solution
Antenna structures are integrated into the display area of electronic devices, allowing for improved space utilization by disposing them in the bezel areas alongside other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna structures are mounted in traditional locations, then signal transmission and reception can be achieved, but the device lacks sufficient space due to other components
Solution Approach 1:
The patent merges the antenna structure with the display assembly by integrating the antenna into the bezel area of the display. The antenna is disposed between the cover glass and the display panel, utilizing the existing structural space rather than adding separate mounting areas. This combining approach allows the antenna to share space with other components while maintaining its signal transmission function.
Solution Approach 2:
The patent transitions from traditional two-dimensional antenna placement on the device surface to three-dimensional integration within the display assembly's depth. The antenna is positioned in the vertical space between the cover glass and display panel, effectively utilizing the Z-dimension (thickness direction) to resolve space constraints in the X-Y plane.
2Adaptability or versatility
If multiple components are mounted on the device, then device functionality is enhanced, but space for antenna disposition becomes limited
Solution Approach 1:
The antenna structure is nested within the display assembly's structural layers. Specifically, the antenna is positioned between the cover glass and the display panel, utilizing the existing structural envelope created by other components. This nesting approach allows multiple components to coexist in a compact arrangement without requiring additional external space.
3Productivity
If antenna array is used for ultra-high-frequency band, then signal transmission efficiency is improved, but space requirements for antenna structure increase
Solution Approach 1:
The patent applies local quality by concentrating the antenna elements in a specific localized region (the bezel area of the display) rather than distributing them across the entire device surface. The antenna array is precisely positioned in the space between the cover glass and display panel, optimizing signal transmission in the ultra-high-frequency band while confining the structure to a compact local area.
