摘要： A pulse-width modulated backlight control for a video display restarts the pulse-width modulated pulse train on occurrence of a video refresh pulse. In order to prevent an undesirable momentary increase in brightness in the event that the last pulse of the pre-refresh pulse train occurs too close to the first pulse of the post-refresh pulse train relative to the normal pulse interval, the width of the first pulse following refresh may be reduced from a first value determined by the desired brightness to a second value that bears the same proportion to the first value that the interval between the beginning of the previous pulse and the occurrence of the refresh pulse bore to the normal pulse interval. In that way, the duty cycle during the shortened pulse interval is the same as during a normal pulse interval, avoiding or minimizing perceptible increase in backlight brightness.

摘要： An electronic device may include a display and display control circuitry. The display may be calibrated to reduce color non-uniformity in the display. Display calibration information may be obtained during manufacturing and may be stored in the electronic device. The display calibration information may include color-specific, intensity-specific, location-specific correction factors. During operation of the display, display control circuitry may receive pixel data to be displayed by each pixel in the display. The pixel data may include color information and intensity information for each pixel. Based on the color information for each pixel, the intensity information for each pixel, and the location of each pixel in the display, the display control circuitry may determine a color-specific, intensity-specific, location-specific correction factor to apply to the pixel data for each pixel. Adapted pixel data may be supplied to each pixel in the display.

摘要： A method, system, and apparatus that can be used to operate a display device in an energy efficient manner. The energy efficient display device can effectively and efficiently compensate for changes in ambient light incident at a display screen of the display device using an internal ambient light sensor to provide control signals to a backlight driver. Data from the ambient light sensor can be at least partially corrected to correspond more closely to a response of a Lambertian responsive light sensor
