Integrated Circuit Chip Counter-Distortion for VR Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality (VR) apparatuses face delays in image processing due to counter-distortion tasks performed by Graphics Processing Units (GPUs), which affect user experience and increase power consumption as resolution and data processing demands rise.
Innovation Solution
An integrated circuit chip (IC) processes images pre-received from the GPU, performing counter-distortion and pre-processing tasks, such as enlargement and low-definition processing, to reduce the GPU's workload and enhance efficiency.

Engineering Contradiction Analysis
1Manufacturing precision
If the GPU performs counter-distortion processing on high-resolution images, then the image quality is maintained, but the processing delay increases and power consumption rises
Solution Approach 1:
The patent divides the display area into multiple regions (first display area, second display area, third display area) with different resolution requirements. The CPU generates high-resolution images only for the first display area (central region), while the second and third display areas (peripheral regions) use lower resolution. This segmentation reduces the total number of pixels that require high-definition counter-distortion processing, thereby decreasing GPU workload and processing delay while maintaining perceived image quality in the central viewing area.
Solution Approach 2:
The patent applies different quality levels to different regions of the display. The central first display area receives high-resolution images with full counter-distortion processing, while the peripheral second and third display areas receive lower-resolution images. This local quality differentiation ensures that the highest image quality is provided only where the user's eyes are most likely to focus, reducing overall processing requirements and power consumption while maintaining acceptable visual experience.
2Manufacturing precision
If the GPU processes high-resolution images for counter-distortion, then the image detail is preserved, but the power consumption increases
Solution Approach 1:
The patent segments the display regions into high-priority central area and low-priority peripheral areas, applying high-resolution processing only to the central first display area where image details are most critical for user experience. The peripheral second and third display areas use reduced resolution, significantly reducing the total pixel count requiring intensive GPU processing and associated power consumption.
Solution Approach 2:
Different quality levels are applied locally to different display regions. The central region maintains high image detail with full resolution, while peripheral regions accept lower detail. This approach preserves essential image quality where needed while reducing overall power consumption by avoiding unnecessary high-resolution processing in peripheral areas that contribute less to the user experience.
3Manufacturing precision
If the resolution of the display screen is increased, then the image quality improves, but the GPU workload and data transmission bandwidth increase
Solution Approach 1:
The patent divides the display into segmented regions with different resolution requirements. The central first display area maintains high resolution for quality image display, while the second and third display areas use lower resolution. This segmentation reduces the total number of pixels that require high-definition processing, thereby improving GPU processing efficiency and reducing data transmission bandwidth requirements while maintaining acceptable overall display quality.
Solution Approach 2:
The patent implements local quality differentiation across the display screen, providing high resolution only in the central viewing area where users are most likely to focus their attention. Peripheral regions accept lower resolution, which significantly reduces the total data volume requiring GPU processing and transmission bandwidth, thereby improving overall system productivity without noticeably degrading the user experience.
