Display Panel Lens Layout for Adaptive Driver-Passenger Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses for vehicles have fixed regions that limit the viewability of images, making it inconvenient for drivers and passengers as the image displayed on a fixed region can only be viewed from specific seats.
Innovation Solution
A display panel and apparatus with a display area divided into first and second regions, each containing subpixels with distinct light emitting elements and lens regions, allowing for independent control of viewing angles through separate light emitting control transistors and signals, enabling adjustable ratios of these regions to optimize viewing angles for both drivers and passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed regions are provided for wide viewing angle mode and narrow viewing angle mode, then the display apparatus can provide different viewing angles for driver and passenger, but the image displayed on the fixed region is limited in where it is viewable from
Solution Approach 1:
The display panel dynamically adjusts the ratio between the first area (wide viewing angle) and second area (narrow viewing angle) based on detection results. The detection unit identifies whether the observer is a driver or passenger, and the control unit accordingly modifies the display area allocation, transforming the fixed region concept into a dynamic, adaptive system that responds to real-time observer identity
Solution Approach 2:
The system incorporates a detection unit that provides feedback about the observer's identity (driver or passenger) to the control unit. This feedback loop enables the control unit to adjust the display area ratio in real-time, ensuring the appropriate viewing angle mode is active for the current observer, thereby resolving the viewability limitation of fixed regions
2Adaptability or versatility
If the first area and second area are fixedly provided, then the display apparatus can independently control viewing angles in different regions, but there is an inconvenience that the image displayed on the fixed region may be limited in where it is viewable from
Solution Approach 1:
The display panel dynamically adjusts the ratio between the first area (wide viewing angle) and second area (narrow viewing angle) based on detection results. The detection unit identifies whether the observer is a driver or passenger, and the control unit accordingly modifies the display area allocation, transforming the fixed region concept into a dynamic, adaptive system that responds to real-time observer identity
Solution Approach 2:
The display panel applies different viewing angle characteristics to different local regions (first area for wide viewing angle, second area for narrow viewing angle). Each region maintains its specific optical properties through dedicated lens regions, allowing independent control of viewing angles in different areas while the overall ratio between areas can be dynamically adjusted
