Abstract

Provided are a charging device and a wireless charging device. The charging device may include: a power supply unit that provides charging power; a charging unit that transmits the charging power from the power supply unit to an external charging target device; a charging control unit that controls the charging state of the charging unit; and a display unit that controls the charge according to the charging control unit displaying the state of charge, and when the charge target device is in a fully charged state, stopping the display operation; and a delay unit, when the charge target device is recharged in the fully charged state, blocking the current supplied to the display unit, and stopping the display unit operation of the display is delayed by a preset time.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2013-0160334 filed in the Korean Intellectual Property Office on December 20, 2013, the disclosure of which is hereby incorporated by reference. technical field [0002] The present disclosure relates to a charging device and a wireless charging device capable of easily displaying a charging state of a device. Background technique [0003] Generally, in order to drive electronic devices, a power supply device that provides driving power is required. [0004] Such power supplies typically convert commercially available AC power to DC power, drive the power, and provide the drive power to electronic devices. [0005] As described above, in the case where a rechargeable battery storing power to supply driving power to an electronic device is adopted for use in the electronic device, a charging device is generally used to supply power to the rechargeable battery. [0006] Such a charging device may s...
