Vehicle Display Light Adjusting Structure for Driver Passenger Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-mounted display devices restrict drivers and passengers from viewing different types of information simultaneously, leading to a poorer user experience as drivers cannot watch information unrelated to driving while passengers cannot watch desired content.
Innovation Solution
A display device with a light adjusting structure that directs light from first and second display units to separate visible areas, using lens groups with strip-shaped lenses and light shielding layers to ensure that the driver and passenger can view different images without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display panel is used for both driver and passenger viewing, then the device structure remains simple, but the driver and passenger cannot view different information simultaneously
Solution Approach 1:
The display panel is divided into two independent display regions: a first display region for displaying driving information to the driver, and a second display region for displaying entertainment content to the passenger. This segmentation allows different information to be displayed simultaneously to different users without requiring separate display devices, thus improving viewing capability while maintaining relatively simple structure.
Solution Approach 2:
Different regions of the same display panel are assigned different functions and display different types of content. The first display region is optimized for driving information (such as navigation, speed, alerts) while the second display region is optimized for entertainment content (such as movies, music videos). This local differentiation enables each user to view appropriate content for their needs simultaneously.
2Adaptability or versatility
If the display panel shows driving information only, then the driver can focus on driving-related content, but the passenger cannot watch entertainment content
Solution Approach 1:
The display panel is divided into two independent display regions: a first display region for displaying driving information to the driver, and a second display region for displaying entertainment content to the passenger. This segmentation allows different information to be displayed simultaneously to different users without requiring separate display devices, thus improving viewing capability while maintaining relatively simple structure.
Solution Approach 2:
The single display panel serves multiple functions: it acts as both a driving information display (for safety and navigation) and an entertainment device (for passenger amusement). This multi-functionality eliminates the need for separate devices while ensuring that driving information remains the primary function, thereby not compromising driving safety.
3Adaptability or versatility
If the display panel shows entertainment content only, then the passenger can watch desired content, but the driver cannot access driving-related information
Solution Approach 1:
The display panel is divided into two independent display regions: a first display region for displaying driving information to the driver, and a second display region for displaying entertainment content to the passenger. This segmentation allows different information to be displayed simultaneously to different users without requiring separate display devices, thus improving viewing capability while maintaining relatively simple structure.
Solution Approach 2:
Different regions of the same display panel are assigned different functions and display different types of content. The first display region is optimized for driving information (such as navigation, speed, alerts) while the second display region is optimized for entertainment content (such as movies, music videos). This local differentiation enables each user to view appropriate content for their needs simultaneously.
4Adaptability or versatility
If separate display devices are used for driver and passenger, then both can view different information simultaneously, but the device complexity and space requirement increase
Solution Approach 1:
Two separate display functions (driving information display and entertainment display) are merged into a single display panel. The display panel is divided into two independent display regions that can simultaneously display different content for the driver and passenger respectively. This merging reduces the number of display devices from two to one, thereby reducing space requirements and device complexity while maintaining the capability for simultaneous viewing of different information.
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
Enables drivers to view driving-related information and passengers to watch entertainment without interference, enhancing user experience by allowing simultaneous viewing of distinct content.
Implementation Method 1
The light adjusting structure includes a plurality of lens groups, each of the lens groups includes a first strip-shaped lens and a second strip-shaped lens
Implementation Method 2
each of the lens groups includes a first strip-shaped lens and a second strip-shaped lens, and the first strip-shaped lens and the second strip-shaped lens respectively correspond to a group of the first display groups and a group of the second display groups
Implementation Method 3
The lens group further includes a first light shielding layer arranged between the first side and the second side and coming into contact with the first side and the second side

AI summary
The present disclosure provides a display device and a vehicle, and relate to the field of display technologies. When the present disclosure is applied to a vehicle, a driver and a passenger may see different images, and thus user experience is enhanced. A display device includes: a display panel and a light adjusting structure arranged at a light exiting side of the display panel. The light adjusting structure is configured to adjust a direction of exit light from the display panel, such that first images displayed by all first display units in the display panel and second images displayed by all second display units in the display panel are respectively transmitted to a first visible area and a second visible area.
