A terminal device, a method and an apparatus for configuring the terminal device are disclosed. The directional focus navigation engine may receive directional input for changing the input focus of a user interface object in the user interface. The apparatus also includes at least one sensor that estimates at least one operating parameter associated with the continuous circulation device. This position information is used for control of a cursor or other GUI interface. The second set of transistors can be the same or different sizes depending on the desirable number of adjustment options. An amount of light corresponding to an amount of light incident on an organic EL display is measured and an output voltage is divided by an output voltage dividing section based on a light amount voltage being a result from the measurement and an output voltage is adjusted by the organic EL display power source based on the divided voltage.
