Pixel Circuit Lens Layout for Driver-Passenger Viewing Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses in vehicles face challenges in properly displaying content without distracting the driver, necessitating a solution to adjust the viewing angle based on the driving mode.
Innovation Solution
A display apparatus with a pixel circuit comprising multiple light emitting elements and lenses, where each element emits light based on specific light emission signals and is paired with a corresponding lens to adjust the viewing angle, allowing for different viewing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display apparatus shows content to the driver during driving, then the driver receives information, but the driver's concentration may be disrupted
Solution Approach 1:
The patent applies local quality by creating different viewing angle zones for different display areas. The first display area (driver area) has a first viewing angle range optimized for driver visibility, while the second display area (passenger area) has a second viewing angle range. This allows information to be delivered to the driver without distracting them, as the content is optimized for their specific viewing position and angle.
2Adaptability or versatility
If the display apparatus uses a single viewing angle for all areas, then the structure is simple, but it cannot provide optimized viewing experience for different users
Solution Approach 1:
The patent segments the display into multiple independent pixel circuits, each with its own light emitting elements and viewing angle control capabilities. The first pixel circuit controls the first display area with first viewing angle characteristics, while the second pixel circuit controls the second display area with second viewing angle characteristics. This segmentation enables different viewing angles for different users without requiring complex centralized control mechanisms.
Solution Approach 2:
The patent implements dynamic viewing angle control by allowing each pixel circuit to independently adjust its light emission characteristics. The viewing angle can be dynamically changed based on which area should be displayed to which user, enabling the display to adapt to different driving conditions and user positions without physical reconfiguration.
3Ease of operation
If the display apparatus provides wide viewing angle for passenger area, then passenger can view content comfortably, but driver may be exposed to distracting content
Solution Approach 1:
The patent applies local quality by creating distinct viewing angle characteristics for different display areas. The first pixel circuit (driver area) uses a first viewing angle range that limits content visibility to the driver only when appropriate, while the second pixel circuit (passenger area) uses a second viewing angle range that provides comfortable viewing for the passenger. This local differentiation ensures passenger comfort without compromising driver safety.
