Display Device Graphics Upscaling With Segmented Multi-Scaler Buffers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices experience image quality degradation when the resolution of original graphics and images is lower than the device's resolution, leading to issues such as blur, especially when upscaling techniques are limited by scaler specifications.
Innovation Solution
A display device with multiple scalers and graphic buffers adaptively upscales graphics to match the device's resolution, allowing for multi-view and single-view display without image quality degradation by dividing graphic data into areas and using multiple scalers to upscale each area independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If upscaling technique is used to increase resolution of original graphics, then image resolution is improved, but image quality deteriorates due to blur
Solution Approach 1:
The graphic buffer is divided into multiple division areas, and multiple scalers are used to upscale different areas simultaneously. This segmentation allows the system to process graphics that cannot be handled by a single scaler, maintaining image quality while achieving high resolution output.
Solution Approach 2:
The patent transitions from using a single scaler to using multiple scalers operating in parallel, adding a dimensional aspect to the upscaling process. This enables handling of graphics with resolutions that exceed single scaler capabilities while preserving image quality.
2Adaptability or versatility
If original graphics are downscaled to address scaler specification limits, then device compatibility is improved, but image quality deteriorates
Solution Approach 1:
By dividing the graphic buffer into multiple areas and using multiple scalers, the system can accommodate scaler specification limits without downsampling the entire image. Each scaler processes a portion of the graphics at full resolution, maintaining image quality while ensuring device compatibility.
3Device complexity
If single scaler is used for upscaling, then device complexity is reduced, but productivity decreases when handling high-resolution graphics
Solution Approach 1:
The graphic buffer is segmented into multiple division areas that can be processed by multiple scalers in parallel. This segmentation enables the system to handle high-resolution graphics efficiently without requiring an overly complex single-scaler configuration, thus improving productivity while maintaining manageable device complexity.
Solution Approach 2:
Multiple scalers are combined to work together on a single graphic buffer, merging their capabilities to achieve high-resolution output. This combination improves processing capability and productivity while distributing the complexity across multiple components rather than concentrating it in a single complex scaler.

AI summary
A display device may include: memory storing instructions; and at least one processor operatively connected to the memory and including at least one graphic buffer and at least two scalers, wherein the at least one processor is configured to execute the instructions to: obtain first graphic data from the memory; determine a size of the at least one graphic buffer to be upscaled by the at least two scalers, based on a resolution of the first graphic data and a resolution of the display device; render the first graphic data to the at least one graphic buffer to generate rendered data; divide the at least one graphic buffer into at least two division areas based on a specification of the at least two scalers; and upscale the rendered data of the at least two division areas using the at least two scalers to obtain at least two upscale graphic data.
