| 20110298765 | Power Calibration of Multiple Light Sources in a Display Screen - A display device with multiple light sources includes a first detector for detecting a brightness of one or more different portions of the image formed on the display device, a second detector that measures output intensities of the light sources, and a controller that records correlation values that correlate input power settings of the light sources with the detected brightness and the measured output intensities. During operation of the display device, the controller applies the correlation values to determine the proper input power settings of the light sources so that brightness uniformity among the multiple light sources can be achieved. | 12-08-2011 |
| 20110298843 | DYNAMIC POWER AND BRIGHTNESS CONTROL FOR A DISPLAY SCREEN - An image is displayed on an electronic display device at a reduced power level. Power used by the display device is maintained below a predetermined maximum power level by uniformly scaling the initial optical intensity of an image to a lower optical intensity whenever displaying the image at the initial optical intensity would result in power consumption of the display device exceeding the predetermined maximum power level. | 12-08-2011 |

| 20110298844 | Power Calibration of Multiple Light Sources in a Display Screen - A display device with multiple light sources includes a detector that dynamically measures output intensities of the light sources as the light sources are producing light to cause an image to be formed on a display screen. A controller for the display device compares the measured output intensities with desired output intensities determined from factory-calibrated correlation values and adjusts the inputs to the light sources to compensate for drift and other similar effects, so that brightness uniformity among the multiple light sources can be achieved. | 12-08-2011 |
