Display Apparatus Partial OSD Data Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face processing speed issues due to the need to handle entire screen data for on-screen display (OSD) images, even though OSDs occupy only a partial screen, leading to increased load and inefficiency in data processing.
Innovation Solution
A display apparatus and method that includes a receiver, storage, and image processor to receive and store image sets, where the image processor detects regions of the OSD image to be synthesized with the main image, receives only partial data corresponding to those regions, and synthesizes them to generate a final image set, reducing unnecessary data transmission and processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display apparatus transmits and processes entire screen data for OSD images, then the OSD images can be displayed correctly, but the processing load increases and processing speed decreases
Solution Approach 1:
The patent divides the OSD image data into multiple regions based on transparency information. The image processor identifies which regions of the OSD image need to be synthesized with the main image by detecting non-transparent pixels, and only transmits/processes data for those specific regions rather than the entire screen. This segmentation approach maintains display correctness while reducing processing load.
Solution Approach 2:
The patent extracts only the necessary data from the OSD image by using transparency information to identify and separate the regions that require synthesis. The image processor extracts non-transparent pixel data and their corresponding positions, then requests only this extracted data from storage rather than loading the complete OSD image data, thereby reducing processing burden.
2Reliability
If the display apparatus receives and processes complete image data for each frame, then the display output is complete and accurate, but the data transmission bandwidth and power consumption increase
Solution Approach 1:
The patent applies partial action by receiving and processing only the necessary portions of image data. Instead of loading complete frame data from storage for every OSD image, the system uses transparency information to determine exactly which pixel regions are needed, then requests only that partial data. This reduces energy consumption while maintaining display output completeness.
Solution Approach 2:
The patent performs preliminary detection of transparency information in the OSD image before actual data transmission. By pre-identifying which regions contain non-transparent pixels that require synthesis, the system prepares a targeted data request list beforehand, avoiding unnecessary data transmission and reducing power consumption during the actual processing phase.

AI summary
The display apparatus includes a receiver configured to receive a first image set, a storage configured to store a second image set with a size corresponding to the first image set, an image processor configured to receive the first image set and the second image set in units of frames and to synthesize the first image set and the second image set to generate a final image set, and a display configured to display the final image set. The image processor detects a region of the second image set, to be synthesized with the first image set, receives only partial data corresponding to the detected region with respect to the second image set of a next frame after the region is detected, and synthesizes the some received data and the first image set to generate a final image set.
