Vehicle Display Unit with Segmented Stereoscopic Lens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display units either provide planar, featureless images at a high cost due to the use of expensive EL panels for stereoscopic effects or display stereoscopic images but at a higher cost.
Innovation Solution
A display unit with a controller that manages scrolling and partitioning mechanisms on a LCD screen, using a ring-shaped partition member with a lens to create stereoscopic images, and a motor-driven transferring mechanism to move the partition, allowing for low-cost, vivid, and novel image displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an EL panel is used to display pointers and create stereoscopic images, then image quality and stereoscopic effect are improved, but manufacturing cost increases
Solution Approach 1:
The display screen is divided into multiple independent display areas (first display area for analog meter, second display area for other information). This segmentation allows different display technologies to be applied to different areas - the EL panel is used only where stereoscopic effect is needed (analog meter pointer) while other areas use standard LCD display, thus reducing overall cost while maintaining image quality where required.
Solution Approach 2:
The invention combines EL panel technology with LCD display technology in a hybrid configuration. The EL panel layer is positioned in front of the LCD screen, allowing the EL panel to provide stereoscopic pointer display for the analog meter while the LCD provides the background dial and additional information display areas, achieving cost-effective stereoscopic imaging.
2Adaptability or versatility
If multiple display areas are used to show different vehicle information simultaneously, then information display capability is improved, but device complexity increases
Solution Approach 1:
The display screen is segmented into a first display area for the analog meter with stereoscopic pointer and a second display area for additional vehicle information. This spatial segmentation allows multiple types of information to be displayed simultaneously without requiring complex multi-screen systems or switching mechanisms, thus improving information display capability while maintaining relatively simple device architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the creation of low-cost, vivid, and stereoscopic display images that mimic analog meters, maintaining appearance quality and functionality while preventing the transferring mechanism from being visible, thus addressing the cost and image quality issues of existing technologies.
Implementation Method 1
a lens fitted into the opening; the lens magnifying the first vehicle related data displayed in the first image area
Data Source
AI summary
A display unit for a vehicle includes a display device having first and second areas on a display screen and a controller. The controller controls the display device to display first vehicle related data at the first area, or to scroll the displayed first vehicle related data from the first area to the second area according to a scrolling signal. The controller controls the display device to display second vehicle related data at the first area after the displayed first vehicle related data is scrolled out of the first area.
