Display Graphics Conversion for Native 8K Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses, such as 8K TVs, can process and display 8K resolution videos but only up to 2K resolution graphics, leading to image quality degradation when trying to display high-resolution graphics in their original resolution.
Innovation Solution
The display apparatus transmits high-resolution graphics to a server for conversion to video data, allowing the graphics to be processed and displayed in their original resolution by converting the color space, and simultaneously processes and displays lower-resolution graphics directly, or processes specific regions of high-resolution graphics differently to mitigate image quality degradation and delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution graphics are processed and displayed directly by the display apparatus, then the original resolution can be maintained, but the display apparatus can only support up to 2K resolution for graphics, causing image quality degradation when 8K graphics are displayed
Solution Approach 1:
The patent introduces a server as an intermediary device between the display apparatus and the graphics source. The server receives graphics data, converts it to video data format, and transmits it to the display apparatus. This intermediary solution enables 8K graphics to be displayed by transforming them into a format compatible with the display apparatus's video processing capabilities, thereby resolving the limitation of direct graphics processing.
Solution Approach 2:
The patent changes the data format parameter of graphics from native graphics format to video data format through server-side conversion. This parameter transformation allows the display apparatus to process high-resolution graphics using its video processing pipeline, which supports higher resolutions than its graphics processing capability would otherwise allow.
2Manufacturing precision
If all high-resolution graphics are converted to video data through a server, then image quality is maintained, but processing delays may occur due to conversion time
Solution Approach 1:
The patent applies different processing strategies to different regions of the screen based on their characteristics. Regions with significant image changes (such as moving objects or dynamic content) are processed as graphics data to minimize delay, while regions with stable images are converted to video data through the server to maintain quality. This localized differentiation resolves the contradiction between quality and speed by optimizing processing for each region's specific needs.
3Adaptability or versatility
If the display apparatus processes both high-resolution and lower-resolution graphics simultaneously, then all content can be displayed, but the processing complexity and resource requirements increase
Solution Approach 1:
The patent segments the processing of different resolution graphics into distinct pathways. High-resolution graphics are routed through the server for video data conversion, while lower-resolution graphics are processed directly by the display apparatus. This segmentation allows the system to handle multiple resolutions simultaneously without overwhelming the processing capabilities, as each resolution type follows an optimized processing route.

AI summary
A display apparatus includes a display, a communicator configured to communicate with a server, and a processor. The processor is configured to control the communicator to transmit graphic data to be displayed on the display to the server, control the communicator to receive from the server video data into which the graphic data is converted, and process and display the received video data on the display.
