A system for managing power on a display panel for a portable electronic device according to the present invention is characterized by including a display panel that outputs visual information only on an active area including an area having the size smaller than that of a whole area and does not output visual information on an inactive area other than the active area, a battery residual amount detecting module for detecting a battery residual amount of the portable electronic device, and a battery cooperation control module for outputting the visual information, which is displayed on the display panel according to battery residual amount states, within the active area. According to the system for managing the power on the display panel for the portable electronic device of the present invention, the designation state of the active area of the display is actively determined depending on the battery residual amount, the type of an App, and an execution state, so that power required for the driving of the display can be more effectively managed in more detail, and the size of the active area can be variably processed according to the battery residual amount.
