Vehicle Display Frame-Rate Bridging for Seamless Adjacent Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle cockpit systems with multiple displays, differences in frame rates between adjacent displays due to image processing or conversion can cause discomfort for occupants as they may perceive uneven motion between image contents.
Innovation Solution
A display system that includes a first generation unit for generating image content at a first frame rate, a second generation unit for generating image content at a second frame rate, and an inter-area image generation unit to create an inter-area image between display areas, which is then synthesized and outputted with the first and second image content to maintain a consistent visual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are disposed side by side with different frame rates, then display flexibility and content adaptability are improved, but visual comfort and perception consistency deteriorate due to uneven motion between adjacent displays
Solution Approach 1:
The patent introduces an inter-area display region between adjacent displays with different frame rates. This inter-area acts as a mediator that buffers the visual transition between displays with different motion characteristics, preventing direct perception of frame rate differences and eliminating visual discomfort while maintaining display flexibility.
2Object-affected harmful factors
If frame rates are unified across all displays, then visual comfort is improved, but content adaptability and processing efficiency deteriorate
Solution Approach 1:
The patent segments the display system into three distinct functional zones: first display area with first frame rate, inter-area with intermediate frame rate, and second display area with second frame rate. This segmentation allows each zone to operate at its optimal frame rate for its specific content requirements, maintaining processing efficiency while the inter-area ensures visual comfort.
Solution Approach 2:
The patent applies different frame rates to different spatial locations based on local requirements. The inter-area specifically uses an intermediate frame rate between the first and second frame rates to locally buffer visual transitions, while other areas maintain their original frame rates for content-specific optimization.
3Object-affected harmful factors
If inter-area image is introduced between displays with different frame rates, then visual comfort is improved, but system complexity increases
Solution Approach 1:
The patent dynamically adjusts the frame rate of the inter-area display based on the frame rates of adjacent displays. The inter-area frame rate is set between the first and second frame rates, creating a dynamic buffering zone that adapts to different display configurations while maintaining a relatively simple overall system structure.

AI summary
A display system for a vehicle generates a first image content to be displayed at a first frame rate in a first display area, a second image content to be displayed at a second frame rate in a second display area adjacent to the first display area, and an inter-area image to be displayed between the first display area and the second display area. Further, the display system synthesizes and outputs the first image content, the second image content, and the inter-area image.
