Solution Overview

Problem

Organic light-emitting diode (OLED) displays are prone to burn-in, and existing methods to prevent this, such as outputting a screensaver on the entire screen, can interfere with user experience when integrated with video content.

Innovation Solution

A method to control the display module by identifying video data on size, state, and position, and based on user input, adjust screen output to prevent burn-in while maintaining user experience, such as outputting video content on a full area or activating a protective screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a screensaver is output on the entire screen to prevent burn-in, then burn-in prevention is improved, but user experience is worsened when video content is displayed

Engineering Contradiction:
Improveburn-in preventionVSAvoiduser experience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies local quality by differentiating the screen protection strategy between different display regions. When video content is detected, the screensaver is selectively applied only to regions not occupied by video content, rather than the entire screen. This allows burn-in prevention in static regions while maintaining video content visibility and user experience in dynamic regions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making the screensaver output adaptive and changeable based on real-time detection of video content. The system dynamically adjusts whether to output the screensaver, and if so, in which regions, based on the presence and characteristics of video content. This dynamic adjustment resolves the contradiction between static burn-in prevention and dynamic user experience.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a screensaver is output on the full screen, then burn-in prevention is improved, but video content visibility is worsened

Engineering Contradiction:
Improveburn-in preventionVSAvoidvideo content display area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent applies local quality by spatially differentiating the screen protection strategy. The screensaver is selectively output only in specific regions of the display that are not occupied by video content. This allows the system to maintain burn-in prevention in static regions while preserving the full video content display area in regions where video is present, thus resolving the contradiction between protection and visibility.

Inventive Principle:
Principle #3Local quality

3Reliability

If the display module outputs protective screen continuously, then burn-in prevention is improved, but energy consumption increases

Engineering Contradiction:
Improveburn-in preventionVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by making the screensaver output conditional and intermittent rather than continuous. The system periodically detects whether video content is present and adjusts screensaver output accordingly. The screensaver is activated only when needed (when no video content is detected or in regions without video content) and deactivated when video content is present, creating a periodic on-off pattern that reduces energy consumption while maintaining burn-in prevention.

Inventive Principle:
Principle #19Periodic action

AI summary

A method of controlling a display and an electronic device for performing the method are disclosed. A determination is made whether a video object in a playback state is output on a partial area of a display based on video data including information of the video object. The video object is output on a full area of the display in response to an input to the electronic device not being received in an input waiting time and the video object in the playback state being output on the partial area of the display.
