Electronic display with environmental adaptation of display characteristics based on location

An electronic display assembly comprising:

• an electronic display;
• and
• a display controller in electrical connection with the electronic display and adapted to:
• determine sunset and sunrise times for each day, including a sunset transition period and a sunrise transition period,
• determine if a present time is during the sunrise transition, daytime, the sunset transition, or nighttime,
• calculate artificial ambient sensor data (AAS) for sunrise and determine a desired gamma based on the AAS data if the present time is during the sunrise transition period,
• determine a desired daytime gamma if the present time is daytime,
• calculate artificial ambient sensor data (AAS) for sunset and determine a desired gamma based on the AAS data if the present time is during the sunset transition period,
• determine a desired nighttime gamma if the present time is nighttime, and
• drive the electronic display at the desired gamma;
• wherein gamma refers to a mathematic exponent in a power function Sγ that is adapted to transform scaling of gray levels in a displayed image, where S represents a normalized value of an image signal;
• and
• wherein the AAS data, depending on time of day, takes into account:
• data that approximates ambient light level for a display environment;
• the sunrise transition period;
• and the sunset transition period.

An electronic display assembly comprising:

• an electronic display;
• a backlight positioned behind the electronic display such that the electronic display is adapted to be directly backlit by the backlight;
• a GPS device;
• and
• a display controller in electrical connection with the electronic display and the GPS device and adapted to:
• determine location data for the electronic display through the GPS device,
• determine sunrise and sunset times for a given day,
• direct the electronic display to utilize a first gamma setting if a present time is between sunrise and sunset, and
• direct the electronic display to utilize a second gamma setting if the present time is between sunset and sunrise;
• wherein gamma refers to a mathematic exponent in a power function Sγ that is adapted to transform scaling of gray levels in a displayed image, where S represents a normalized value of an image signal.
