Solution Overview

Problem

Existing large screen systems, such as smart TVs and public electronic bulletin boards, display a black screen when turned off, which is not harmonious with the ambient environment, as they do not adapt to their surroundings.

Innovation Solution

A display apparatus that photographs its rear environment and processes the images to display a background image consistent with the ambient environment, using an image obtainer, processor, and controller to determine and display the appropriate image based on preset conditions and location data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a black screen is displayed when the display apparatus is turned off, then power consumption is reduced and the display structure is simple, but the visual consistency with the ambient environment deteriorates

Engineering Contradiction:
Improvepower consumptionVSAvoidvisual consistency with ambient environment
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The system captures images of the ambient environment in advance and stores them for later display. When the display apparatus is turned off, the pre-captured background image is displayed instead of a black screen, maintaining visual consistency without requiring continuous power consumption for environment monitoring.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a visual copy of the ambient environment by capturing images with an image obtainer and displaying them on the screen. This copy replaces the black screen output, allowing the display to reflect the surrounding environment without requiring the display apparatus to remain fully operational.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If the display apparatus continuously monitors and updates the background image to maintain environmental consistency, then visual adaptability is improved, but power consumption and system complexity increase

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of continuous monitoring, the system periodically captures background images at specific intervals or when triggered by certain conditions. This periodic operation maintains environmental adaptability while significantly reducing power consumption and system complexity compared to continuous real-time monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The display apparatus uses its own display screen to show the captured background image, effectively serving dual purposes: the display functions both as the primary output device and as the background display device. This self-service approach eliminates the need for separate hardware components, reducing system complexity.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If image processing is performed to enhance the background image quality, then image quality is improved, but processing time and energy consumption increase

Engineering Contradiction:
Improveimage qualityVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system applies image processing selectively rather than to all captured images. Basic processing such as brightness adjustment is applied to maintain visual consistency, while more intensive processing is reserved for specific conditions. This partial action approach maintains adequate image quality without excessive processing time.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A display apparatus includes an image obtainer configured to photograph images; an image processor configured to process the photographed images; a display; and a controller configured to determine one of the photographed images that satisfies a preset condition and is within a predetermined range, as a background image, to control the image processor to process the determined background image corresponding to an image effect that has been transmitted to the controller regarding the background image, and to control the display to display the processed background image.
