Claim Text:
1. A portable device comprising: a foldable display unit including a first display region and a second display region; a state sensor unit configured to detect a folded state and an unfolded state of the foldable display unit; an input sensor unit configured to sense user input; and a processor configured to control the foldable display unit, the state sensor unit and the input sensor unit, wherein the portable device provides a dimming mode for dimming at least a part of the foldable display unit when the user input is not sensed for a dimming time, wherein the processor is further configured to: convert the portable device from a first dimming mode to a second dimming mode upon detection of change of the foldable display unit from the unfolded state to the folded state, wherein the first dimming mode provides a first dimming time, wherein the second dimming mode provides a second dimming time different with the first dimming time; perform dimming of the foldable display unit upon reaching the second dimming time when the user input is not sensed in the second dimming mode within the second dimming time; and perform dimming of the foldable display unit based on a dimming time different with the second dimming time when the user input is sensed in the second dimming mode within the second dimming time.
