Abstract
A method for automatic adjusting brightness includes receiving pixel information. The pixel information are analyzed to obtain an image load. The image load is compared with a predetermined range. If the image load is less than the range, then a display duty cycle is set to be an upper limit. If the image load is greater than the range, then the display duty cycle is set to be a lower limit. If the image load is in the range, then the display duty cycle is set to an operation quantity between the upper limit and the lower limit, according to a current image load. Further, according to the changing of display duty cycle, two ranges are set to have the hysteresis effect.
