Noise Blocking Structure for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As electronic devices become more compact and multifunctional, they experience performance degradation due to noise interference from internal components, particularly from touch screen modules, which affects peripheral components and reduces device reliability.
Innovation Solution
Implementing a noise blocking structure by grounding noise sources through connecting portions on both sides of the noise source, creating a ground region that intercepts and blocks noise radiation to peripheral components, thereby preventing performance degradation.

1Volume of moving object
If electronic devices are slimmed and components are placed closer together to improve portability, then device size and weight are reduced, but noise interference between components increases
Solution Approach 1:
A ground connecting portion is introduced as an intermediary element between noise sources and peripheral electronic components. This ground connection acts as a mediator that provides a controlled path for noise currents, preventing them from interfering with sensitive components while allowing the device to maintain its compact form factor.
Solution Approach 2:
The noise blocking function is extracted and implemented through a dedicated ground connecting portion that is selectively placed between noise sources and sensitive components. This separate grounding path extracts noise currents from the signal paths, allowing compact component placement without compromising signal integrity.
2Object-affected harmful factors
If ground connecting portions are added to block noise, then noise interference is reduced, but device complexity increases
Solution Approach 1:
The ground connecting portion is merged with the existing ground structure of the device. Rather than adding completely separate noise blocking components, the solution integrates grounding connections into the existing device architecture, reducing overall structural complexity while maintaining effective noise blocking.
Solution Approach 2:
The ground connecting portion serves multiple functions simultaneously: it provides a reference potential for electronic components, creates a noise blocking barrier, and establishes a return path for currents. This multi-functionality reduces the need for additional dedicated components, thereby limiting increases in device complexity.

Function Achieved in This Case
This approach enhances the reliability of electronic devices by preventing noise interference, allowing for the slimming of devices while maintaining performance, and securing the reliability of electronic components.
Implementation Method 1
The noise radiated from the noise source is blocked from being radiated to at least one peripheral electronic component by a first ground region formed by the first connecting portion and a second ground region formed by the second connecting portion

AI summary
Various embodiments of the present invention relate to an electronic device having a noise blocking structure comprising: a first electronic component including a noise source; a first connecting portion disposed on one side of the noise source and grounded to a first grounded portion; and a second connecting portion disposed on the other side (such that the noise source is between the second connecting portion and the first connecting portion) and grounded to a second grounded portion. By means of a first grounded region formed by the first connecting portion and a second grounded region formed by the second connecting portion, the noise generated from the noise source is prevented from emanating at least to a second electronic component nearby so as to prevent a degradation in the performance of nearby electronic components.
