Multi-Lens Display Pixel Layout for Driver-Specific Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses in vehicles struggle to adjust their viewing angle to prevent distraction to drivers without compromising the display of important information.
Innovation Solution
A display apparatus with a pixel circuit comprising multiple light emitting elements and lenses that adjust the viewing angle based on different light emission signals, allowing for separate control of light emission and lens configurations in different areas to optimize visibility for the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display apparatus in a vehicle displays contents to provide information to the driver, then the driver receives necessary information, but the driver's concentration on driving may be disrupted
Solution Approach 1:
The display apparatus applies different viewing angle characteristics to different regions of the display. The first region has a first viewing angle and the second region has a second viewing angle different from the first, allowing critical driving information to be visible only to the driver while other content is visible to passengers or not visible at all from the driver's position.
2Adaptability or versatility
If the display apparatus uses a single viewing angle for the entire display, then the structure is simple, but it cannot selectively control visibility for different viewers
Solution Approach 1:
The display area is divided into multiple regions with different viewing angle characteristics. The display apparatus includes a first region with a first viewing angle and a second region with a second viewing angle, allowing independent control of visibility for each region to achieve selective viewing without requiring the entire display to have complex adjustable structures.
3Ease of operation
If the display apparatus provides wide viewing angle to ensure all passengers can see, then visibility for all users is improved, but the driver may be distracted by visible content
Solution Approach 1:
Different regions of the display have different viewing angle characteristics optimized for their specific purpose. The first region is configured with a viewing angle optimized for driver visibility of critical information, while the second region has a viewing angle that allows passenger viewing without causing driver distraction, thus locally optimizing visibility for each user group.
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
The solution effectively adjusts the viewing angle to minimize driver distraction while ensuring critical information is clearly visible, enhancing safety and usability of in-vehicle displays.
Implementation Method 1
a lens disposed on each of the first light emitting element, the second light emitting element, and one of the third and fourth light emitting elements

AI summary
A display apparatus includes a display panel including a pixel area. The pixel area may include a first lens area and a second lens area respectively configured to provide viewing angles different from each other, a first light emitting element positioned in the first lens area, and a second light emitting element positioned in the second lens area. The first lens area may include at least one first lens, and the second lens area may include two or more second lenses. A planar shape of the at least one first lens may be different from a planar shape of the two or more second lenses.
