VR Display Synchronization Compensation for High-Resolution Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR display technologies face limitations in achieving ultra-high resolution due to long rendering times and reduced refresh rates, which are constrained by hardware and software limitations, making it impossible to achieve high frame rates and resolutions.
Innovation Solution
A compensation method and device for VR display that calculates a synchronization signal value based on rendering resolution, frame rate, and bandwidth, comparing it to a pre-stored value, and generating compensation image data to insert between frames when the calculated value exceeds the stored value, thereby reducing transmission bandwidth requirements and improving display performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultra-high resolution is implemented in VR display, then visual effect is improved, but rendering time increases and frame rate decreases
Solution Approach 1:
The patent pre-calculates and stores synchronization signal values corresponding to different resolution and frame rate combinations before actual display operation. When displaying, the system directly queries the pre-calculated values rather than computing them in real-time, avoiding computational delays that would reduce frame rate while still achieving ultra-high resolution display
2Productivity
If high resolution and high frame rate are simultaneously achieved, then display performance is improved, but transmission bandwidth requirement increases
Solution Approach 1:
The patent dynamically adjusts the synchronization signal parameter based on the relationship between resolution and frame rate. By changing this timing parameter, the system optimizes data transmission scheduling to reduce peak bandwidth requirements while maintaining high frame rate display performance

AI summary
A compensation method for VR display, a compensation device for VR display, and a display device are provided. The compensation method for VR display includes: calculating a first synchronization signal value to be output by a controller according to a rendering resolution, a rendering frame rate and bandwidth data of a display panel; comparing the first synchronization signal value with a pre-stored second synchronization signal value of the display panel; generating compensation image data between two adjacent frames of original image data in a case where a comparison result shows that the first synchronization signal value is greater than the second synchronization signal value; and compensating an image to be displayed according to generated compensation image data.
