Abstract

A device and a method are provided. In a terminal capable of at least one of a wireless charging function and a near field communication (NFC) function, the device displays operation states of the functions via an e-skin unit. Wireless charging efficiency, a charging state, and a communication state may be selectively or totally displayed to a user.

First claim

What is claimed is:

1. A method comprising:
storing color tables respectively corresponding to each of a communication operation state of a communication unit, a charging operation state, and a charging efficiency of a wireless charging unit;
receiving a user command of selecting a condition from among communication operation state, the charging operation state, and the charging efficiency;
checking an operation state of a device corresponding to the selected condition; and
controlling a color of an e-skin unit of the device according to the checked operation state, wherein the color of the e-skin unit is determined based on the color tables;
wherein if the selected condition is the communication operation state, the color of the e-skin unit is controlled based on communication quality of the communication unit;
wherein if the selected condition is the charging operation state, the color of the e-skin unit is controlled based on a charging operation state voltage of the wireless charging unit; and
wherein if the selected condition is the charging efficiency, the color of the e-skin unit is controlled based on the charging efficiency of the wireless charging unit.

2. A device comprising:
a communication unit configured to perform communication with other devices;
a wireless charging unit including a wireless charging coil to charge a battery by power transmitted from a primary coil formed on a wireless charging pad;
an e-skin unit configured to display a color corresponding to any one of a communication operation state of the communication unit, a charging operation state, and a charging efficiency of the wireless charging unit;
a memory configured to store color tables respectively corresponding to the communication operation state, the charging operation state, and the operation state of the charging efficiency;
an input unit configured to receive a user command of selecting a condition from among the communication operation state, the charging operation state, and the operation state of the charging efficiency; and
a control unit configured to check an operation state of the device corresponding to the condition, and to control the color of the e-skin unit according to the checked operation state, wherein the color of the e-skin unit is determined based on the color tables;
wherein if the selected condition is the communication operation state, the control unit is configured to control the color of the e-skin unit based on communication quality of the communication unit;
wherein if the selected condition is the charging operation state, the control unit is configured to control the color of the e-skin unit based on a charging operation state voltage of the wireless charging unit; and
wherein if the selected condition is the operation state of the charging efficiency, the control unit is configured to control the color of the e-skin unit based on the charging efficiency of the wireless charging unit.
