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

VSEngineering 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

Engineering Contradiction:
Improvedisplay areaVSAvoidantenna performance
Core Design Contradiction:
Area of stationary objectVSReliability

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If antenna elements are integrated within display pixels, then antenna clearance is improved, but the device structure becomes more complex

Engineering Contradiction:
Improveantenna clearanceVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of energy

If radio frequency front-end circuit is integrated into the display, then transmission loss is reduced, but manufacturing complexity increases

Engineering Contradiction:
Improvetransmission lossVSAvoidmanufacturing complexity
Core Design Contradiction:
Loss of energyVSEase of manufacture

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

Inventive Principle:
Principle #5Merging (Combining)
