Solution Overview

Problem

Existing display devices with integrated antennas face challenges in reducing the size of the antenna while maintaining efficient wireless signal transmission and reception, particularly in portable devices like notebook computers where space is limited.

Innovation Solution

The integration of a chip antenna on the driving circuit substrate of the display device, positioned at the end portion in the longitudinal direction, allows for reduced size and enhanced wireless communication capabilities by using a dielectric or helical monopole type chip antenna configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional antenna is installed on the display part of a notebook computer, then wireless communication capability is provided, but the size and weight of the device increase

Engineering Contradiction:
Improvewireless communication capabilityVSAvoiddevice weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent combines the antenna function with the display panel by integrating the antenna into the bezel or frame structure of the display device. This merging of functions allows the antenna to be part of the existing display structure rather than a separate component, thereby enabling wireless communication without significantly increasing overall device weight

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display panel structure is designed to serve multiple functions: displaying images and housing the antenna for wireless communication. The bezel or frame of the display panel acts as both a structural element and an antenna support, providing multi-functionality without requiring additional dedicated space or weight

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

2Adaptability or versatility

If a conventional antenna is installed on the display part of a notebook computer, then wireless communication capability is provided, but the overall size of the device increases

Engineering Contradiction:
Improvewireless communication capabilityVSAvoiddevice area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The antenna is merged with the display panel structure, specifically utilizing the bezel or frame area. This integration allows the antenna to occupy space that is already part of the display assembly rather than requiring additional external space, thereby maintaining a compact overall device size

Inventive Principle:
Principle #5Merging (Combining)

3Area of stationary object

If the antenna size is reduced to minimize device size, then device compactness is improved, but wireless signal transmission and receiving efficiency deteriorates

Engineering Contradiction:
Improveantenna sizeVSAvoidwireless signal transmission efficiency
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The patent employs parameter changes by using materials with specific electromagnetic properties (such as high-permeability magnetic shielding materials) to enhance antenna performance. By changing the material parameters rather than increasing the physical size, the antenna maintains effective signal transmission and reception efficiency while keeping a compact form factor

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If magnetic shielding material is added to block external magnetic fields, then display quality is improved, but weight and complexity of the device increase

Engineering Contradiction:
Improvedisplay qualityVSAvoiddevice weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent uses thin-film magnetic shielding materials that can be applied as coatings or laminates on the display panel. These thin films provide the necessary magnetic field blocking to maintain display quality while adding minimal weight and complexity compared to bulk magnetic shielding materials

Inventive Principle:
Principle #30Flexible shells and thin films
