Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing screen-to-body ratio in electronic devices leads to insufficient antenna clearance, resulting in poor antenna performance and communication quality, particularly in devices with high screen coverage.
Innovation Solution
Integrate antenna elements within the display pixels, allowing communication above the display with sufficient clearance, and incorporate the radio frequency front-end circuit to reduce transmission loss and enhance electromagnetic wave radiation and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen-to-body ratio is increased to achieve higher screen coverage, then the display area is improved, but the antenna clearance becomes insufficient resulting in poor antenna performance
Solution Approach 1:
The patent merges the display function and antenna function into a single integrated structure. The antenna elements are disposed within the display panel structure, specifically in the light-shielded regions of pixels, allowing the display to serve dual purposes: visual display and wireless communication, thereby resolving the contradiction between maximizing display area and maintaining antenna performance
Solution Approach 2:
The patent transitions the antenna communication from traditional side-clearance configuration to a vertical dimension by enabling electromagnetic wave radiation and reception in the thickness direction of the electronic device. This dimensional shift allows antenna elements to function effectively within the constrained planar space of high screen-to-body ratio devices
2Reliability
If antenna elements are integrated within display pixels, then antenna clearance is improved, but the device structure becomes more complex
Solution Approach 1:
The patent combines multiple functions (display and antenna) into a single integrated structure, where the antenna elements are disposed within the display panel structure. This merging approach increases functional integration while maintaining a unified manufacturing process, thereby managing structural complexity through functional consolidation
Solution Approach 2:
The display panel is designed to serve multiple functions: visual display through pixel structures and wireless communication through integrated antenna elements. This multi-functionality reduces the need for separate antenna components and simplifies the overall device architecture despite the increased functional integration
3Loss of energy
If radio frequency front-end circuit is integrated into the display, then transmission loss is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent merges the radio frequency front-end circuit with the display structure, integrating it into the light-shielded regions of the display panel. This integration shortens the transmission distance between the antenna elements and the radio frequency front-end module, reducing signal loss while consolidating manufacturing processes into a single integrated structure
