Display brightness control based on location data
First Claim
1. An electronic display assembly comprising:
- an electronic display;
a light adapted to provide lighting for the electronic display;
a microprocessor adapted to;
i) determine a geographical location of the electronic display;
ii) determine sunrise and sunset times for a day based on the geographical location;
iii) determine a present time;
iv) control power to the light such that the light is adapted to operate at a daytime level if the present time is between sunrise and sunset; and
v) control power to the light such that the light is adapted to operate at a nighttime level that is less than the daytime level if the present time is between sunset and sunrise;
wherein the light is adapted to be on for daytime use and nighttime use of the electronic display.

Abstract
The exemplary embodiments herein provide an electronic display assembly having a liquid crystal display, a backlight placed behind the liquid crystal display, one or more power modules in electrical connection with the backlight, and a microprocessor in electrical connection with the power module(s). Said microprocessor is adapted to determine the sunset and sunrise times for each day and determine whether the present time is between sunrise and sunset or between sunset and sunrise. The microprocessor is further adapted to direct the power module(s) to drive the backlight at a daytime level if the present time is between sunrise and sunset, and direct the power module(s) to drive the backlight at a nighttime level if the present time is between sunset and sunrise.

26. An electronic display assembly comprising:
-
an electronic display; a light adapted to provide lighting for the electronic display; and a microprocessor adapted to; i) determine a geographical location for the electronic display; ii) determine sunset and sunrise times for a day based on the geographical location of the electronic display, including a sunset transition period and a sunrise transition period; iii) determine a present time; iv) determine if the present time is during the sunrise transition, daytime, the sunset transition, or nighttime; v) calculate artificial ambient sensor (AAS) data for sunrise and control power to the light based on the AAS data if the present time is during the sunrise transition period; vi) control power to the light at a daytime level if the present time is daytime; vii) calculate artificial ambient sensor (AAS) data for sunset and control power to the light based on the AAS data if the present time is during the sunset transition period; and viii) control power to the light at a nighttime level that is less than the daytime level if the present time is nighttime; wherein the light is adapted to be on for daytime use and nighttime use of the electronic display. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
