Dashboard Passenger Display With Filtered Viewing Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road vehicle passenger display devices often distract the driver, limiting entertainment options for the front passenger and increasing the risk of driver distraction during vehicle operation.
Innovation Solution
A passenger content display device integrated into the dashboard with a filter element and adjustable brightness, using existing vehicle sensors to ensure the passenger can view content without distracting the driver, by limiting the viewing angle and dynamically adjusting brightness based on external light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display device is provided for the front passenger to view distracting contents, then passenger entertainment is improved, but driver distraction increases
Solution Approach 1:
The display device implements different viewing characteristics for different spatial zones: the first viewing area (passenger side) allows full-color distracting contents while the second viewing area (driver side) presents monochrome or reduced-color versions. This spatial differentiation of display properties resolves the contradiction by enabling passenger entertainment without exposing the driver to distracting visual stimuli.
Solution Approach 2:
The display device dynamically adjusts the visual properties presented to different viewers based on real-time detection of viewer position and vehicle motion state. When the vehicle is in motion, the system automatically modifies content presentation for the driver's viewing area, transforming the static display into an adaptive system that responds to operational conditions.
2Adaptability or versatility
If the display shows full-color distracting contents to the passenger, then passenger entertainment quality is improved, but driver visibility of road conditions deteriorates
Solution Approach 1:
The display implements spatially differentiated color rendering where the first viewing area maintains full-color capability for high-quality passenger entertainment, while the second viewing area applies color filtering or monochrome presentation. This ensures that bright, distracting colors are not visible to the driver, preserving road visibility while maintaining entertainment quality for the passenger.
3Adaptability or versatility
If the display allows the passenger to view distracting contents during vehicle operation, then passenger entertainment is improved, but safety deteriorates
Solution Approach 1:
The display system dynamically responds to vehicle motion state detection, automatically adjusting content presentation based on whether the vehicle is stationary or in motion. During operation, the system modifies the driver-facing viewing area to prevent distraction, while allowing full entertainment functionality for the passenger, thereby maintaining safety without sacrificing entertainment capability.
Solution Approach 2:
The display device incorporates detection means that continuously monitor vehicle motion state and viewer position, using this feedback to automatically adjust content presentation. When motion is detected, the system modifies the display output for the driver's viewing area, creating a closed-loop safety mechanism that adaptively prevents distraction while maintaining entertainment.
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
Prevents driver distraction while enhancing passenger entertainment by ensuring the display is only visible to the passenger and adjusting brightness to optimize visibility, thus reducing the risk of accidents.
Implementation Method 1
a filter element (7) determining a viewing area (8) from which it is possible to view the contents
Implementation Method 2
a backlighting element (10)
Implementation Method 3
a control unit (15), which adjusts a brightness of the display device according to an amount of light present outside the road vehicle (1)

AI summary
A content display device for a passenger of a road vehicle; the content display device comprising: a support element configured to be mounted on a dashboard of the road vehicle; at least one screen mechanically connected to the support element and configured so as to be visible to the passenger while the vehicle is driven; a filter element, which determines a viewing area, from which it is possible to view the contents while the vehicle is driven; the viewing area comprising the point of view of the passenger and not the point of view of the driver.
