First, when given a physical address, the system can determine the sunrise/sunset times based on this address and store them within the electronic storage on the display controlling assembly 20.

While the figure reads the logic as "does the current time fall after sunset and before sunrise,” it seems clear that this could also be performed by determining "does the current time fall after sunrise and before sunset” and it makes no difference in any of the subject embodiments. In this first embodiment, if the system determines that it is currently nighttime, the backlight is driven at the nighttime level. Alternatively, if the system determines that it is daytime, the backlight is driven at the daytime level.
  • the relative daytime level and nighttime level for the backlight can be selected for this embodiment through a simple binary operation where a first luminance value for the backlight is desired during nighttime and a second luminance value for the backlight is desired during daytime.
  • the system may push as much power as necessary to the backlight 23 in order to read the desired luminance value from the backlight sensor 29.
  • the power levels can be adjusted through the feedback coming from the backlight sensor 29 to ensure that the desired luminance level of the backlight 23 is maintained.

  • the sensor 40 can also provide the feedback to the system to ensure that the proper amount of power is being sent to the backlight 23 to ensure adequate luminance levels exiting the display.
  • FIGURE 3 provides a logical flow chart for performing a second embodiment of the method which is controlled initially by data from the ambient light sensor 28 but switches to display location data if a failure is observed in the ambient light sensor 28.
  • the system regularly checks to determine if the ambient light sensor 28 is working properly. This can be checked in a number of ways, including a quick reference to the time of day and the ambient light sensor readings. Thus, if it is 3:00 a.m. in Lincoln, Iowa, we should see very low light levels and a very high light level reading would indicate some error or failure in the ambient light sensor 28. Alternatively, if it is 3:00 p.m.
  • failures in the ambient light sensor 28 can also be determined by signal analysis methods which look at the amount of noise and randomness in the sensor data. A measured amount of noise or randomness that is above some threshold level can also be used to indicate a failure in the sensor.
  • the ambient light sensor 28 is working properly, it is preferably used to determine the amount of luminance contacting the front display panel 25. Based on this information, the system may determine the desired backlight level based on this data. This step can also be performed in a number of ways. First, a lookup table may be used where a particular reading from the ambient light sensor 28 will correspond with a desired luminance reading from the light sensor 29 in the backlight cavity or light sensor 40 in front of the display 24. Second, an equation or ratio can be used where the desired luminance from the light sensor 29 or light sensor 40 may be calculated based on the data from the ambient light sensor 28.
  • the more simplistic daytime/nighttime settings can be used when the sensor 28 indicates daytime/nighttime and when the sensor 28 indicates a transition period (i.e. dawn/dusk) the display may default to the daytime setting. [0041] If at any point during this operation the system determines that the ambient light sensor 28 is not working properly, the system preferably shifts to the display location data method described above.
  • FIGURE 4 provides a logical flow chart for performing a third embodiment of the method which is controlled based on the display location data in the nighttime but switches to control based on the ambient light sensor 28 in the daytime.
  • This is a type of hybrid approach where the backlight is driven at a desired (preferably constant) nighttime level anytime the display is between sunset and sunrise while adjusting to the various levels of ambient light when operating during the daytime or other transition periods (i.e. dawn/dusk).
  • FIGURE 5 provides a logical flow chart for performing a fourth embodiment of the method which is controlled based on the display location data in the nighttime but switches to control based on the ambient light sensor 28 in the daytime unless a failure is detected in the ambient light sensor 28, at which point the system is controlled only by the display location data.
  • This embodiment is similar to the embodiment shown and described for Figure 4 above, with the additional check to see if the ambient light sensor 28 is functioning properly. If not, then the backlight may be driven to a desired daytime level (preferably constant) based on the time of day, and will not consider the readings of the ambient light sensor.
  • the system when driving the backlight based on the location data and/or time of day, the system does not have to choose one luminance for daytime and one luminance for nighttime (although some embodiments use this method).
  • the system can also use the time of day to slightly adjust the amount of luminance from the backlight.
  • 7:15 a.m. and 1 :30 p.m. are each occurring after sunrise and before sunset, the system does not have to drive the backlight at the same luminance for each time.
  • the terms "nighttime level” and "daytime level” can represent luminance values that are also obtained through a lookup table (based on time of day) or an equation/calculation (based on time of day).
  • the system could drive the daytime level at 1 :30 p.m. higher than the daytime level at 7:15 a.m. given the assumption that there will be more ambient light present during the afternoon than in the early morning (or late evening for that matter).
  • FIGURE 6 provides a graphical representation of a desired display brightness in response to raw ambient light sensor data. This is an example, and not required for any specific embodiment. It has been found, that the human eye is more sensitive to luminance variations in low ambient light environments as compared to high ambient light environments. Therefore, some embodiments of the invention may use a more aggressive response curve at the lower ambient light environments.
  • FIGURE 7 provides a graphical representation of a desired display brightness in response to raw ambient light sensor data for this type of curve where the low ambient environments require a display set to a higher luminance level. Either curve (Fig. 6 or Fig. 7), or another curve, could be used to create the look-up table or perform an equation to determine the desired display brightness for each ambient environment.
  • Figures 6 and 7 are shown in terms of display brightness, the exemplary embodiments herein can be based on either display brightness or backlight brightness, depending on which type(s) of electronic display is being used and the sensors used to measure the luminance output (if used). It should also be noted that the values for Figures 6 and 7 are based on actual raw data from ambient light sensors, but actual data is not necessarily used when using some of the exemplary embodiments herein. Thus, the calculation of artificial ambient sensor (AAS) values is described below, and these AAS values can be used with the relationships shown in Figures 6 and 7 to determine the desired display brightness.

  • changes from "nighttime level” backlight luminance to "daytime level” backlight luminance should preferably not happen in a drastic manner, where an abrupt change or flicker in the display could be observed by a viewer.

Abstract

La présente invention concerne, dans les modes de réalisation décrits à titre d'exemple, un procédé et un système destinés à commander la luminance d'un affichage électronique, comprenant la détermination des heures de coucher et de lever du soleil pour la journée et la détermination du fait que l'heure actuelle se situe entre le lever et le coucher du soleil ou entre le coucher et le lever du soleil. Le rétro-éclairage peut être attaqué à un niveau diurne si l'heure actuelle se situe entre le lever et le coucher du soleil, tandis que le rétro-éclairage peut être attaqué à un niveau nocturne si l'heure actuelle se situe entre le coucher et le lever du soleil. Dans certains modes de réalisation, un microprocesseur peut traiter des données de capteurs d'ambiance artificielle (AAS) pour déterminer la luminance de rétro-éclairage ou d'affichage souhaitée. Les données d'AAS peuvent être ajustées pour tenir compte d'une heure de transition de coucher ou de lever du soleil, ainsi que d'un pourcentage approximatif de couverture nuageuse dans le ciel.
