Partial Frame Buffer Allocation for High Resolution UI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in providing a user interface (UI) with a resolution corresponding to high resolution content due to memory space and memory bandwidth limitations, making it difficult to efficiently display high-quality digital broadcasts.
Innovation Solution
The display apparatus allocates partial frame buffers based on the size and location of UI regions on the screen, allowing for the same resolution display of video content and UI, thereby optimizing memory usage and bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional display apparatus attempts to display high resolution content with a corresponding high resolution UI, then the image quality of the UI matches the content quality, but the memory space and memory bandwidth requirements become excessively high
Solution Approach 1:
The patent divides the frame buffer into multiple regions: a first region for video content and a second region for UI elements. By segmenting the buffer allocation, the system can allocate different resolutions to different regions, allowing the UI region to use a lower resolution than the full screen resolution, thereby reducing memory space and bandwidth requirements while maintaining acceptable UI quality
Solution Approach 2:
The patent applies different quality levels to different parts of the display. The video content region maintains high resolution (e.g., 4K) while the UI region uses a lower resolution (e.g., 1080p or lower). This local differentiation allows the system to optimize memory usage by not allocating full high resolution to all elements, particularly to UI elements where lower resolution is less perceptible
2Manufacturing precision
If a conventional display apparatus attempts to display high resolution content with a corresponding high resolution UI, then the image quality of the UI matches the content quality, but the memory bandwidth consumption increases
Solution Approach 1:
The patent segments the frame buffer into distinct regions for video content and UI elements, allowing independent resolution control. This segmentation reduces the total amount of data that needs to be transferred to the display memory, thereby reducing memory bandwidth consumption while maintaining high resolution for the video content region
Solution Approach 2:
The patent applies partial high resolution allocation - only the video content region receives full high resolution data, while the UI region receives reduced resolution data. This partial application of high resolution where most needed (video content) while accepting lower resolution elsewhere (UI) reduces overall bandwidth requirements
3Manufacturing precision
If a display apparatus uses enhanced processing speeds and greater storage capacity to display high resolution content and UI, then the resolution correspondence is achieved, but the device complexity increases
Solution Approach 1:
The patent segments the frame buffer into multiple regions with different resolution allocations. This segmentation allows the system to avoid using a single high-resolution buffer for all elements, reducing the total memory capacity needed and simplifying the memory configuration while still achieving high resolution for the video content

AI summary
An approach for providing a user interface having a resolution corresponding to a resolution of a high resolution content is provided. The approach allocates at least one partial frame buffer based on a size and a location of a region on a screen of a display on which a user interface (UI) is displayed. The approach displays the UI based on at least one piece of partial graphic data obtained from the allocated at least one partial frame buffer.
