Multi-layer Display System for Vehicle Dash Depth Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems, including stereo and multi-layer displays, struggle to effectively convey depth information and often cause discomfort such as eye strain and double vision, while also being limited in displaying volumetric blended surfaces.
Innovation Solution
A multi-layer display system using three or more display screens in a stacked arrangement, where each screen displays a gradient that overlaps with others to create a three-dimensional image by progressively changing color from closer to farther, mimicking inclined surfaces and providing depth cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If stereo displays are used to convey depth information, then depth perception is improved, but viewing angle is limited and viewer discomfort increases
Solution Approach 1:
The display system is segmented into multiple independent display layers (at least two layers), with each layer displaying specific depth information. This segmentation allows different portions of the image to be displayed at different depths, enabling volumetric blended surfaces while maintaining broad viewing angles through geometric arrangement of the layers.
2Measurement precision
If two display screens are stacked to provide real depth, then depth information is improved, but volumetric blended surfaces cannot be displayed
Solution Approach 1:
The patent extends the conventional two-layer display into three or more layers arranged in a triangular or pyramidal geometric configuration. This dimensional extension from planar stacking to spatial arrangement enables the display of volumetric blended surfaces by distributing image portions across multiple depth planes, creating realistic three-dimensional effects.
3Measurement precision
If gradients are displayed on multiple display screens to provide depth information, then depth perception is improved, but device complexity increases
Solution Approach 1:
Multiple display layers are merged into a single integrated display system with unified control. The processing system coordinates all layers to display complementary gradient information simultaneously, creating a cohesive three-dimensional image. This merging approach maintains depth perception benefits while managing system complexity through integrated architecture.

AI summary
A multi-layer display system may include three, four, or more display panels/screens arranged in an overlapping manner, a backlight configured to provide light to the plurality of display screens, and a processing system. The processing system may be configured to display, on a first display screen of the plurality of display screens, a first image including a first gradient area, display, on a second display screen of the plurality of display screens, a second image including a second gradient area, and display, on a third display screen arranged in an overlapping manner between the first display screen and the second display screen, a third image including. The third image may include a third gradient area overlapping at least a portion of the first gradient area displayed on the first display screen and at least a portion of the second gradient area displayed on the second display screen.
