Abstract: An electronic display device includes a housing for an electronic display to form an assembly. A thermal management subsystem forms part of the assembly and utilizes ingested ambient air from immediately outside said assembly to thermal manage the assembly. Data is received from one or more sensors pertaining to at least one characteristic of the ingested ambient air at times during operation of the assembly. Operating parameters of the assembly are automatically adjusted when the data indicates a difference in the measured at least one characteristic at the times, and when said difference exceeds a threshold value.

Abstract: Condensation control systems and methods for display assemblies are provided. A cover forms part of a housing for an electronic display, the housing accommodating an airflow pathway. Temperature sensors located along the airflow pathway measure temperature which is reported to a controller. The controller determines a dewpoint temperature and calculates a dewpoint spread between the dewpoint temperature and the measured temperature. Where the dewpoint spread is less than a predetermined threshold, modified operations are initiated by the controller.

Abstract: The exemplary embodiments herein provide a method for environmental adaptation of electronic display characteristics, comprising the steps of determining the sunset and sunrise times for the day and determining whether the present time is between sunrise and sunset or between sunset and sunrise. An exemplary method would then proceed by selecting a gamma for the display based on whether the present time is between sunrise and sunset or between sunset and sunrise, and driving the display at the selected gamma. The gamma can further be selected based on Artificial Ambient Light Sensor (AAS) data, which can be calculated during sunrise and sunset transition times.

Abstract: The exemplary embodiments herein provide an electronic display with a display controller in electrical connection with the electronic display and adapted to direct the electronic display to operate per nighttime instructions if the present time is between sunrise and sunset, without accepting any input from an ambient light sensor, and direct the electronic display to operate per daytime instructions if the present time is between sunset and sunrise, without accepting any input from an ambient light sensor. The nighttime instructions may include a first setting for gamma while the daytime instructions may include a second setting for gamma. Sunrise and sunset transition periods can be calculated using Artificial Ambient Sensor Data (AAS), with further settings for gamma chosen based on the AAS data.

Abstract: An electronic display system having an electronic display with illumination control, wherein illumination control may be based on one or both of the system operating temperature and a light ratio defined as the ratio of ambient light to light emitted by an illumination means of the electronic display. When adjusting the emitted light level of the illumination means, some exemplary system embodiments may consider temperature only, some embodiments may consider light ratio only, and some embodiments may consider both temperature and light ratio. Sensors may be provided to measure system operating temperature, as well as ambient light level and illumination means light output. Illumination control is provided by using a controller to adjust the output of a power source that supplies electrical energy to the illumination means if the temperature and/or light ratio falls outside of an acceptable range.
