Viewer-Aware Image Displacement Control for Self-Luminous Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with self-luminous elements suffer from image burn-in when images are displayed at high luminance for extended periods, and displacement techniques to mitigate this cause viewer distraction due to visible image position changes.
Innovation Solution
A control unit that displaces the image position on the display panel until a viewer is detected, then suspends the displacement to prevent distraction and image burn-in, using sensors to determine viewer presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the position of the image is displaced in the display panel at regular intervals, then image burn-in is restrained, but the viewer is undesirably distracted by the displacement
Solution Approach 1:
The patent implements dynamic control of image displacement by detecting viewer presence and adjusting displacement behavior accordingly. When a viewer is detected, displacement is stopped or reduced; when no viewer is present, displacement continues at regular intervals. This dynamic adjustment resolves the contradiction by making the displacement behavior adaptive to viewing conditions.
Solution Approach 2:
The patent uses viewer detection signals as feedback to control the displacement operation. The detection unit provides real-time information about viewer presence to the control unit, which then adjusts whether to perform displacement. This feedback mechanism allows the system to automatically balance image burn-in prevention with viewer comfort.
2Reliability
If image displacement is performed continuously, then image burn-in is prevented, but display stability deteriorates when viewers are watching
Solution Approach 1:
The system dynamically adjusts displacement frequency based on viewing conditions. During active viewing, displacement is stopped or performed at reduced frequency, maintaining display stability. When viewing is detected to have ceased, displacement resumes to prevent burn-in. This dynamic behavior resolves the contradiction between continuous displacement for burn-in prevention and stability during viewing.
Solution Approach 2:
The patent changes the displacement parameter (frequency or amount) based on detection results. When viewers are present, the displacement parameter is reduced or set to zero; when viewers are absent, the parameter returns to normal operational levels. This parameter adjustment resolves the contradiction by adapting displacement intensity to viewing conditions.

AI summary
A control unit for a display device includes a display panel including a plurality of self-luminous elements, the control unit including a displacement control unit configured to, while causing to displace a position in the display panel where an image is displayed on the display panel, stop the displacement of the position of the image in the display panel when a viewing signal is received that indicates that a viewer is likely to be watching the display panel.
