Vehicle Optical Display Intensity Control for Clear Emphasized Objects

The patent applies local quality by dividing the display area into multiple regions and assigning different light intensity levels to each region based on its importance and ambient conditions. Critical information areas receive higher intensity while less important areas use lower intensity, thereby improving overall visibility without causing excessive light leakage or obscuring ambient objects uniformly across the entire display.

The system dynamically adjusts the light intensity of light emitting units in real-time based on detected ambient light conditions and the importance of displayed information. This dynamic adaptation allows the display to optimize visibility under varying environmental conditions while preventing light leakage and object obscuration by reducing intensity when ambient light is sufficient or when displaying less critical information.

Instead of uniform adjustment, the patent implements localized light intensity control where different regions of the display are independently adjusted based on their specific requirements. Critical safety-related information is highlighted with appropriate intensity while non-critical areas use lower intensity, ensuring that important information remains visible without causing light leakage that would compromise driving safety.

The system employs color or luminance contrast changes to differentiate between critical and non-critical information. By varying the optical properties of different display regions, the system enhances the visibility of safety-critical information while maintaining a lower overall intensity profile that prevents light leakage and preserves the visibility of ambient objects, thereby maintaining driving safety.
