Display Brightness Control for Afterimage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with displays using light-emitting elements face performance differences due to varying light-emitting times, leading to afterimages and visual instability as some light-emitting elements deteriorate over time.
Innovation Solution
An electronic device with a processor that identifies brightness information for multiple content layers and controls the brightness of overlapping image layers based on differences, ensuring consistent display attributes to prevent performance differences and afterimages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light-emitting elements are used to display content, then display functionality is achieved, but performance differences and afterimages occur due to varying light-emitting times
Solution Approach 1:
The processor performs preliminary identification of brightness information for multiple image layers before display, and pre-controls the brightness attributes to prevent performance differences. By preparing and adjusting display attributes in advance, the system prevents afterimages caused by unequal light-emitting durations of different pixels.
2Reliability
If brightness of multiple image layers is controlled based on brightness information, then afterimages are prevented, but processing complexity increases
Solution Approach 1:
The processor applies local quality control by identifying and controlling brightness attributes specifically for the second image layer based on its brightness information and the brightness information of the first image layer. This targeted approach adjusts only the necessary layer's attributes rather than processing all layers uniformly, thereby preventing afterimages while minimizing additional processing complexity.

AI summary
Various embodiments of the present invention relate to an electronic device for adjusting voltage and an operation method therefor. The electronic device may comprise: a display; and a processor, wherein the processor is configured to: identify first information which relates to the brightness of at least one first content included in a first image layer and is to be displayed using the display, and second information which relates to the brightness of at least one second content included in a second image layer and is to be displayed using the display; adjust the brightness of the second content at least on the basis of a difference between the first information and the second information; and in a state where the second image layer is superimposed on the first image layer including the first content, display the at least one first content, and the second content the brightness of which has been adjusted, using the display. Other embodiments are also possible.
