ABSTRACT:
A method is for calibrating a contrast offset value for an LCD contrast control system in a mobile device. The method includes the steps of adjusting a user contrast setting on the mobile device to a desired optimal value, initializing the contrast offset value, determining a contrast ratio of the LCD, and incrementing the contrast offset value until the contrast ratio reaches a peak value.
