Solution Overview

Problem

Current image display apparatuses lack the capability to efficiently display and manage mirroring images from multiple external devices, such as mobile terminals, tablets, and laptops, leading to user inconvenience in selecting and arranging mirroring content.

Innovation Solution

An image display apparatus with a display, an interface unit for data exchange with external devices, and a controller that performs control operations to display mirroring images from multiple external devices, allowing pairing, preview, and selection of mirroring content, including determining display locations based on remote control device signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the image display apparatus displays only one mirroring image at a time, then the display is simple and easy to manage, but the user cannot view or compare content from multiple external devices simultaneously

Engineering Contradiction:

Improvecapability to display multiple mirroring imagesVSAvoidcomplexity of managing and selecting mirroring content

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display screen is segmented into multiple regions, with each region dedicated to displaying a mirroring image from a different external device. This allows simultaneous display of multiple mirroring images while maintaining organized and manageable presentation, resolving the contradiction between versatility and complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from displaying mirroring images in time sequence (one after another) to displaying them in spatial arrangement (simultaneously in different screen regions). This dimensional change enables multiple images to coexist on the display without increasing operational complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the apparatus provides detailed options for selecting and arranging mirroring images, then user control and customization are improved, but the operation becomes more complex and time-consuming

Engineering Contradiction:

Improveease of selecting and arranging mirroring contentVSAvoidtime required for selection and arrangement operations

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system automatically detects external devices and assigns display regions based on device type and content characteristics, eliminating the need for manual configuration. This self-service approach maintains ease of operation while significantly reducing the time required for setup and arrangement.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by automatically detecting available external devices, pre-arranging display regions, and preparing mirroring connections before the user needs to view content. This preliminary setup reduces operational time while maintaining user-friendly control options.

Inventive Principle:

Principle #10Preliminary action

AI summary

An image display apparatus including a display; a first interface configured to exchange data with at least first and second external devices; and a controller configured to when a first mirroring image is received from the first external device, display the first mirroring image on the display, and when a second mirroring image is received from the second external device, display the second mirroring image on the display.
