Vehicle Display Controller for Synchronized Multi-Screen Link Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle interiors, the existing techniques for displaying linked animations across multiple display units often result in deviations in timing, causing a strange user experience due to individual processing by respective display controllers, which reduces processing speed and leads to timing discrepancies between display units.
Innovation Solution
A vehicle controller with a single display processing unit that preprocesses and outputs link images to multiple display units, forming a mixed image with synchronized frame rates and resolutions, reducing timing deviations by sharing preprocessing tasks and outputting images simultaneously across units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple display controllers individually process display images for multiple display units, then each display controller can independently control its display unit, but timing deviations occur between display units causing strange user experience
Solution Approach 1:
The patent merges the preprocessing functions of multiple display controllers into a single display processing unit. This central化的 processing unit performs all preprocessing operations (scaling, formatting, etc.) for all display units, ensuring that all display units receive synchronized processed images simultaneously, thereby eliminating timing deviations while maintaining independent control capabilities through separate output paths.
Solution Approach 2:
The patent segments the display system into two functional parts: a centralized display processing unit for preprocessing and multiple independent output units for distribution. This segmentation allows the preprocessing to be centralized for synchronization while the output distribution remains independent, resolving the contradiction between centralized control and independent operation.
2Adaptability or versatility
If multiple display controllers individually process display images, then display control flexibility is maintained, but processing speed decreases leading to timing discrepancies
Solution Approach 1:
By combining the preprocessing operations of multiple display controllers into a single display processing unit, the system achieves higher processing speed through consolidated resource utilization. The single processing unit can efficiently process all display images in sequence, eliminating the overhead of multiple independent processing operations while maintaining flexibility through configurable output settings for each display unit.
3Adaptability or versatility
If link images with different screen resolutions are displayed across multiple display units, then display unit compatibility is improved, but image synthesis complexity increases
Solution Approach 1:
The display processing unit applies local quality transformation by processing each link image according to the specific resolution requirements of its target display unit. Each image undergoes localized scaling and formatting operations tailored to its destination, allowing the system to accommodate various display resolutions without requiring complex global image synthesis algorithms.
