Problem
Existing display devices lack the capability to provide a three-dimensional effect and selectively display vehicle status information and content images, compromising safety and user satisfaction.
Innovation Solution
A display device comprising a first display panel and a translucent second display panel that can be moved in front of the first panel, allowing for superimposed images and touch sensing, with driver circuits controlling operations to enhance three-dimensional effects and selective image display based on vehicle status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a single display panel is used, then the device structure is simple, but it cannot provide three-dimensional effect images
Solution Approach 1:
The patent implements a nested structure where a second display panel is positioned in front of a first display panel, with the second panel being movable between a retracted position (aligned with the first panel) and a protruding position (creating three-dimensional effect). This nesting approach allows the system to achieve three-dimensional display capability only when needed, while maintaining a flat profile during normal operation, thus resolving the contradiction between three-dimensional effect and structural simplicity.
Solution Approach 2:
The second display panel is designed to be movable rather than fixed, allowing it to dynamically change position between retracted and protruding states. This dynamic capability enables the display device to switch between two-dimensional and three-dimensional display modes, providing three-dimensional effect when required while maintaining structural simplicity during normal use.
2Shape
If multiple display panels are superimposed, then three-dimensional effect is achieved, but the device complexity increases
Solution Approach 1:
The control system is designed to manage multiple display panels through a unified control architecture that can selectively activate different display modes. The system can display various types of content (vehicle status information, navigation, entertainment) on either panel or both panels simultaneously, making the control system multi-functional and reducing the need for separate dedicated controls for each panel.
Solution Approach 2:
The system includes a controller that pre-determines which display mode to use based on detected vehicle status. When the vehicle is stationary, the controller automatically positions the second display panel to protrude and activates three-dimensional display mode. This preliminary action based on vehicle status detection simplifies the control complexity by automating the decision-making process.
3Shape
If the second display panel is fixed in front of the first panel, then three-dimensional display is always available, but it blocks the first panel and reduces visibility
Solution Approach 1:
The second display panel is designed with movable capability, allowing it to dynamically switch between a retracted position (where it aligns with the first panel, maximizing visibility) and a protruding position (where it creates three-dimensional effect). This dynamic positioning resolves the contradiction by ensuring that the second panel only blocks the first panel when three-dimensional display is actively being used.
Solution Approach 2:
The controller detects vehicle status and preliminarily determines the appropriate display mode before activation. When the vehicle is moving, the controller keeps the second panel retracted to maintain maximum visibility of the first panel. When the vehicle is stationary, the controller activates the second panel in the protruding position for three-dimensional display, thus preventing unnecessary blocking.
4Reliability
If vehicle status information is always displayed, then driver awareness is improved, but it reduces content display options
Solution Approach 1:
The display system is designed to dynamically adapt its content based on detected vehicle status. When the vehicle is in motion, the system prioritizes displaying vehicle status information on the first display panel to ensure driver safety. When the vehicle is stationary, the system switches to displaying content images and entertainment on both panels in three-dimensional mode, thus providing both safety and versatility at different times.
Solution Approach 2:
The controller preliminarily determines the display content based on vehicle status detection before actual display activation. This preliminary determination ensures that appropriate information is prioritized for display based on current driving conditions, automatically switching between safety-critical information and entertainment content without requiring manual intervention.
