Pixel Mapping Layout for High-Resolution Displays Under Bandwidth Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies struggle to manage increasing visual display resolution demands, particularly in head-mounted displays for VR and AR, leading to excessive bandwidth requirements and computational intensity due to the need for high-resolution image rendering across the entire display area.
Innovation Solution
The technique involves partitioning the display panel into primary and secondary regions, using a 1-to-1 mapping for the primary region and 1-to-M mapping for secondary regions, with dynamic or static adjustments based on viewer focus, to reduce image data size and transmission bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution image data is transmitted to the display panel, then display resolution is improved, but transmission bandwidth requirements increase excessively
Solution Approach 1:
The display panel is divided into multiple regions (first region, second region, third region) with different resolution requirements. The first region receives full-resolution pixel values, while the second and third regions receive downsampled pixel values, reducing overall bandwidth requirements while maintaining high resolution where needed.
Solution Approach 2:
Different regions of the display panel are assigned different quality levels of image data. The first region (center area) receives high-quality full-resolution data, while the second and third regions (peripheral areas) receive lower-quality downsampled data, optimizing the balance between resolution and bandwidth consumption.
2Measurement precision
If high-resolution pixel data is processed for the entire display area, then image quality is improved, but computational load increases excessively
Solution Approach 1:
The computational processing is segmented by region. Full-resolution pixel values are processed and transmitted only to the first region, while downsampled pixel values are processed and transmitted to the second and third regions, reducing overall computational load while maintaining image quality in the first region.
Solution Approach 2:
Instead of processing full-resolution data for the entire display area, the system applies full-resolution processing only where necessary (first region) and uses reduced-resolution processing for peripheral regions, avoiding excessive computational effort in areas that do not require high detail.
3Stability of the object's composition
If uniform high-resolution mapping is applied across all display regions, then consistency is improved, but bandwidth and computational resources are wasted in peripheral areas
Solution Approach 1:
The display is segmented into regions with different mapping ratios. The first region uses a 1:1 mapping ratio for pixel values to display pixels, while the second and third regions use lower mapping ratios (e.g., 1:2 or 1:4), reducing bandwidth consumption in peripheral areas while maintaining consistency in the center.
Solution Approach 2:
Different mapping ratios are applied locally to different regions based on their functional requirements. The first region maintains 1:1 mapping for high-quality display, while peripheral regions use reduced mapping ratios, optimizing resource allocation without compromising overall system consistency.

AI summary
Techniques are described for controlling display of video data and/or other image data based at least in part on selective mapping of pixel values to pixels. Such techniques may include separating a display panel into multiple regions, with at least one primary region having a highest resolution of displayed image data and with one or more secondary regions having one or more lower resolutions of displayed image data (e.g., by using a 1-to-M mapping of image pixel values to display panel pixels for each such secondary region, where M is greater than 1, such that each such image pixel value controls the display of M such pixels). The image data may further be encoded and optionally decoded in accordance with such a display panel arrangement, such as to encode the image data per the display panel arrangement to reduce its size before transmission to the display panel.
