Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with high-resolution displays face increased power consumption and data processing burdens due to the processing of ultrahigh-resolution images, leading to inefficient data handling and power usage.
Innovation Solution
An electronic device with a display driving circuit that processes and stores image frames using an image processor, confirming and displaying a third image frame only if the second frame meets specific conditions, thereby reducing unnecessary processing and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ultrahigh-resolution image processing is performed continuously, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent applies periodic action by selectively processing image frames based on change detection. Instead of continuously processing all frames at full resolution, the system periodically processes only those frames that contain significant changes (determined by comparing with reference frames), thereby reducing overall power consumption while maintaining image quality when needed.
Solution Approach 2:
The patent implements partial action by processing only the necessary portion of image data. When image changes are detected, full-resolution processing is applied; when no significant changes occur, processing is reduced or skipped entirely. This partial processing approach maintains image quality for changed regions while avoiding unnecessary power consumption for unchanged regions.
2Manufacturing precision
If all image frames are processed through the image processor, then image quality is maintained, but data processing burden increases
Solution Approach 1:
The patent extracts and processes only the necessary image frames that contain meaningful changes. By comparing each frame with reference frames and identifying frames that satisfy change conditions, the system extracts only those frames requiring full processing, thereby reducing the data processing burden while maintaining image quality for changed content.
Solution Approach 2:
The system performs partial processing by applying full image processing only to frames that contain significant changes, while skipping or reducing processing for frames without meaningful changes. This selective approach improves data processing efficiency without compromising image quality when changes are detected.
3Manufacturing precision
If high-resolution image data is transmitted and processed continuously, then display quality is improved, but throughput requirements increase
Solution Approach 1:
The patent extracts only the essential image frames that contain visual changes for transmission and processing. By identifying and selecting only those frames that satisfy change detection conditions, the system reduces data throughput requirements while ensuring that high display quality is maintained for frames that actually contain new or changed visual information.

AI summary
An electronic device is provided, which includes a display, a processor configured to generate a plurality of frame images including a first frame image and a second frame image to be provided to the display, and a display driving circuit including an image processor and a memory, and configured to drive the display using the first frame image and the second frame image that are provided from the processor. The display driving circuit is configured to compare the second image frame to the first image frame, to display, through the display, a third image frame obtained through the image processor, the image processor processing the first image frame or the second image frame using an image processing scheme if the second image frame satisfies a first condition, to store the third image frame in the memory and to display the stored third image frame through the display if the second image frame satisfies a second condition.
