Vehicle Display Control for Viewing-Angle Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As vehicle displays become larger and more diverse, they can cause image noise and distractions for drivers due to co-driver seat displays and side-window reflections, necessitating improved viewing angle control technology to limit image visibility to the driver's direction.
Innovation Solution
A display system control device and method that adjusts luminance and color coordinates based on different control modes, using a memory unit to store reference values and a control unit to correct display settings, including gamma correction, to maintain optimal viewing conditions for the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the display size and diversity are increased to provide more information to driver and passenger, then the information delivery capability is improved, but image noise and driver distraction increase
Solution Approach 1:
The patent applies local quality by implementing viewing angle control that creates different display characteristics for different spatial zones. The display shows content with full brightness and color to the driver while automatically darkening or distorting the image for the co-driver seat area, thus providing information to the driver without causing distraction to other passengers
2Object-affected harmful factors
If viewing angle control technology is implemented to limit image visibility to driver direction, then driver distraction is reduced, but display adaptability to different viewing positions is limited
Solution Approach 1:
The patent implements dynamics by making the display characteristics dynamically adjustable based on detected viewing angles. The system continuously monitors the position of viewers and automatically adjusts luminance, color coordinates, and image content in real-time, allowing the display to adapt to different viewing positions while maintaining driver-focused visibility control
3Ease of operation
If luminance and color coordinates are adjusted for different control modes, then viewing comfort is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-storing reference luminance values and reference color coordinate values for multiple different control modes in a memory unit. When a control mode is selected, the system automatically retrieves and applies the corresponding pre-calibrated values, eliminating the need for real-time complex calculations and simplifying the control process while maintaining optimal viewing comfort

AI summary
A display system control device includes: a memory unit storing at least one of a reference color coordinate value for each control mode or a reference luminance value for each control mode, a display color coordinate value, and a display luminance value; and a control unit controlling the display system based on a received control mode and the information stored in the memory unit, wherein based on the received control mode, the control unit corrects the display color coordinate value based on the reference color coordinate value for each control mode, corrects the display luminance value based on the reference luminance value for each control mode, or corrects the display color coordinate value and the display luminance value respectively based on the reference color coordinate value for each control mode and the reference luminance value for each control mode.
