In-Vehicle Display Synchronization with Portable Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a portable information terminal is connected to an in-vehicle electronic apparatus, the lack of synchronization in screen information luminance and tone between the two devices can cause discomfort to users, particularly due to differences in background colors and brightness levels, especially when switching between daytime and night modes.
Innovation Solution
The electronic apparatus notifies the portable terminal of setting information, allowing it to match the luminance and tone of the screen information with the in-vehicle apparatus, ensuring unity in display settings and adjusting brightness and tone based on day-and-night modes detected by the vehicle's illumination system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the background color of the in-vehicle electronic apparatus is set differently from the mobile terminal device, then the display can be customized according to user preference, but the screen colors cannot achieve unity and user comfort is compromised
Solution Approach 1:
The in-vehicle electronic apparatus detects the background color setting of the mobile terminal device and uses this feedback information to automatically adjust its own background color setting, ensuring consistency between the two displays without requiring manual user intervention
Solution Approach 2:
The system dynamically changes the background color parameter of the in-vehicle electronic apparatus based on the detected background color setting of the mobile terminal device, enabling automatic adaptation to maintain display unity
2Illumination intensity
If the screen from mobile terminal device is displayed during night, then the screen information can be viewed in dark conditions, but the screen appears too bright causing discomfort to users
Solution Approach 1:
The system dynamically adjusts the luminance of the displayed screen information based on the detected illumination conditions (daytime/nighttime), automatically reducing brightness during night hours to maintain user comfort
Solution Approach 2:
The luminance parameter of the screen information is changed based on the illumination condition detection, with the system automatically adjusting brightness levels to match the ambient lighting conditions
