Layered Vehicle Display Switching for Lower Map Rendering Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems face increased processing loads when visual effects like fade-in are applied to information displays that change with vehicle location, such as map information.
Innovation Solution
The system employs a layered display architecture where a dummy background layer is used to switch between transparent and opaque states, allowing visual effects to be applied only to non-map information layers, thereby reducing processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If visual effects such as fade-in are applied to map information display, then user satisfaction is improved, but processing load increases
Solution Approach 1:
The display is divided into multiple layers: a first layer for map information, a second layer with a dummy background, and a third layer for other information. Visual effects are selectively applied only to the third layer rather than the entire display, segmenting the processing load and reducing the burden on map information rendering while maintaining visual satisfaction for non-map content.
2Manufacturing precision
If visual effects are applied to all information displays, then display quality is improved, but processing complexity increases
Solution Approach 1:
Different quality levels are applied to different regions of the display. The third layer containing non-map information receives visual effects for high display quality, while the first layer containing map information maintains basic rendering to reduce processing complexity. This local differentiation of quality ensures important navigational information remains clear while enhancing overall display aesthetics.

AI summary
A vehicle display device is configured to superpose a background layer on a first layer for displaying map and/or periphery information, and superpose a layer for displaying information other than the map information and the vehicle periphery information on the background layer. In accordance with a user operation, the display is switched from a transparent background layer where the user can see the information displayed on the first layer to an opaque background layer where the user cannot see the information displayed on the first layer. While switching between the transparent background layer to the opaque background layer, a visual effect is not added to show the switching. After the switch, a transmittance of the background layer is changed and a visual effect is not added to show the switching of the background layer.
