Display Apparatus Synchronized Multi-Plane Image Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in accurately synchronizing the output of multiple images generated on different planes, leading to incomplete or broken images when mixed, causing user discomfort due to asynchronous removal of images from the display.
Innovation Solution
A display apparatus with a processor that generates and manages images on multiple planes, ensuring synchronized output by controlling the removal of images and generating a third image based on the mixed image, preventing incomplete images from being displayed by using planes with different resolutions and priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple images are generated and mixed on different planes, then the display functionality and information presentation are improved, but the synchronization of image output becomes difficult, leading to incomplete or broken images
Solution Approach 1:
The patent applies preliminary action by generating a third image in advance based on the mixed image before the first image is completely removed from the display. This ensures that a complete replacement image is ready, preventing the display from showing incomplete or broken image states during the transition between images on different planes.
2Adaptability or versatility
If images are removed from display at different time points, then the processing of different data formats is improved, but the user experiences discomfort due to incomplete image display
Solution Approach 1:
The patent uses the third image as an intermediary element that mediates between the first image (video content) and the second image (supplemental information). By controlling the display timing of this intermediate third image, the system maintains smooth transitions and prevents user discomfort while still allowing different removal time points for images on different planes.
3Reliability
If a third image is generated based on the mixed image, then image integrity is maintained, but the processing complexity and resource usage increase
Solution Approach 1:
The patent applies the copying principle by generating the third image as a copy or derivative of the mixed image. This allows the system to maintain image integrity with a simplified approach - essentially creating a replacement frame based on the current mixed state - rather than implementing complex synchronization mechanisms across multiple planes and processing pipelines.

AI summary
Provided are a display apparatus and an operation method thereof for preventing image flicker when displaying mixed images: generating a first image corresponding to video content on a first plane, generating, on a second plane, a second image, outputting a mixed image that is a mixture of the first image and the second image, generating a third image on a third plane corresponding to the mixed image, and displaying the third image based on removal of the first image from the display.
