Abstract
An example apparatus for powering a mobile device display includes a first voltage regulator electronically to be electronically coupled to a display backlight and to a power rail. The power rail is coupled to a power source to provide a first voltage within a first range of voltages. The first voltage regulator is to provide a second voltage within a second range of voltages to the display backlight. The apparatus also includes a second voltage regulator to be electronically coupled to display electronics of the mobile device display and the power rail. The second voltage regulator is to provide a third voltage within a third range of voltages to the display electronics. The first range of voltages, the second range of voltages, and the third range of voltages, are different voltages.
