Flexible Vehicle Display Orientation and Curvature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems, such as those using LCD or rigid OLED screens in central control panels, fail to adjust their angle and direction to match the driver's position, leading to reduced safety due to the need for drivers to turn their heads and poor visibility in bright environments, especially with low contrast caused by ambient light reflections.
Innovation Solution
A flexible display module with a supporting backplate and bracket, equipped with sensor devices and motor components, allows the display to automatically adjust its direction and curvature to face the driver, enhancing visibility and reducing the impact of ambient light through controlled bending and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid straight panel display (LCD or straight OLED) is used in the central control panel, then the display structure is simple and cost-effective, but the screen angle is fixed and cannot be adjusted, requiring drivers to turn their heads which affects driving safety
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed rigid display into a flexible adjustable one. The flexible display module can be bent and rotated to different angles and positions, allowing the screen to dynamically adapt to the driver's line of sight and improve driving safety without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The patent utilizes flexible OLED display technology with thin-film structures that allow the display to be bent and shaped. The flexible display module can be conformally arranged on curved surfaces and adjusted to optimal viewing angles, eliminating the need for drivers to turn their heads while maintaining a relatively simple overall structure.
2Area of stationary object
If the central control panel is positioned far from the driver, then the display can be larger and more visible, but the driver must turn their head to operate it, causing sight to leave the driving direction and affecting safety
Solution Approach 1:
The flexible display module can be dynamically positioned and angled to face the driver directly, allowing large display areas to be located at optimal positions without requiring head turning. The adjustability enables the display to maintain visibility while aligning with the driver's natural line of sight.
3Illumination intensity
If the display brightness is increased to overcome ambient light reflection and improve contrast in bright environments, then visibility is improved, but power consumption significantly increases
Solution Approach 1:
The flexible display module can be bent and positioned to optimize its orientation relative to ambient light sources, reducing direct reflection into the driver's eyes. This angular adjustment improves display contrast and visibility in bright environments without requiring excessive brightness increase, thereby maintaining lower power consumption.
