Antenna-Integrated Display Screen for Polarization Mismatch and Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Millimeter-wave antennas in wireless communication devices are prone to performance degradation due to blocking and polarization mismatch, leading to communication dead zones and poor user experience, especially in devices with high screen-to-body ratios.
Innovation Solution
Integrate a plurality of antenna elements with different polarization directions alternately in the display screen, reducing mutual coupling and enhancing beam coverage to improve communication quality and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate antenna is disposed behind a display screen, then antenna function is achieved, but the overall device size increases and integration is reduced
Solution Approach 1:
The patent combines the antenna and display screen into a single integrated structure. The antenna is formed by patterned conductive layers (first and second conductive patterns) that are deposited directly on the display screen substrate, eliminating the need for a separate antenna component and reducing overall device size while maintaining both display and communication functions.
Solution Approach 2:
The display screen substrate serves multiple functions: it acts as both the display surface and the mounting substrate for the antenna. The conductive patterns on the substrate provide both the antenna radiation elements and the necessary electrical connections, allowing one component to fulfill multiple roles in the device.
2Adaptability or versatility
If a separate antenna is disposed behind a display screen, then antenna function is achieved, but the display screen occupies more area
Solution Approach 1:
The antenna structure is merged with the display screen by forming conductive patterns directly on the display substrate. This eliminates the need for additional space behind the display screen for mounting a separate antenna, as the antenna elements are created using the same substrate and conductive material layers that form the display structure.
3Adaptability or versatility
If conductive patterns are formed on display screen, then antenna integration is achieved, but manufacturing complexity increases
Solution Approach 1:
The same conductive material layers and patterning processes used in conventional display manufacturing are utilized to create the antenna structures. The first and second conductive patterns are formed using standard display fabrication techniques, allowing the antenna to be manufactured alongside the display without requiring entirely new manufacturing equipment or processes.
