Abstract

A display device includes: a display operable in a landscape mode and a portrait mode; a stand and including a power circuit configured to receive external power, a first battery, and a charging and discharging circuit configured to control charging and discharging of the first battery; and one or more processors configured to: control the charging and discharging circuit to charge the first battery using the external power, based on a user command for turning on the display being received, provide a portion of the external power to the display as first driving power, and control the charging and discharging circuit to provide another portion of the external power to the first battery as charging power, where the one or more processors are configured to provide output power of the first battery to the display as second driving power in a battery priority use mode.

First claim

What is claimed is:

1 . A display device comprising:
a display operable in a landscape mode and in a portrait mode; a stand configured to support the display, the stand comprising:
a power circuit configured to receive external power;
a first battery; and
a charging and discharging circuit configured to control charging and discharging of the first battery; and
one or more processors configured to:
control the charging and discharging circuit to charge the first battery using the external power,
based on a user command for turning on the display being received, provide a portion of the external power to the display as first driving power, and
control the charging and discharging circuit to provide another portion of the external power to the first battery as charging power,
wherein the one or more processors are further configured to provide output power of the first battery to the display as second driving power in a battery priority use mode by setting a second output voltage of the charging and discharging circuit to be greater than a first output voltage of the power circuit.

2 . The display device as claimed in claim 1 , wherein the one or more processors are further configured to:
adjust an output luminance of the display based on a size of the second driving power in the battery priority use mode, and wherein the output luminance of the display according to the second driving power is less than an output luminance of the display according to the first driving power.

3 . The display device as claimed in claim 1 , wherein the one or more processors are further configured to:
based on the external power not being received from the power circuit, automatically switch to the battery priority use mode, provide the second driving power to the display through a diode connected in parallel to the charging and discharging circuit for a threshold time after the automatic switch to the battery priority use mode, and provide the second driving power to the display through the charging and discharging circuit after the threshold time elapsed.

4 . The display device as claimed in claim 3 , wherein the one or more processors are further configured to:
based on the second driving power provided to the display through the diode for the threshold time being less than a minimum driving power of a plurality of light-emitting diode (LED) elements included in the display, adjust an output luminance of the display to be less than a threshold luminance or turn off the plurality of LED elements for the threshold time.

5 . The display device as claimed in claim 3 , wherein the one or more processors are further configured to:
based on the automatic switch to the battery priority use mode, set the second output voltage of the charging and discharging circuit to be greater than the first output voltage of the power circuit, and based on the external power being received by the power circuit in the battery priority use mode, receive the external power from the power circuit and provide the first driving power to the display, and provide the charging power to the first battery.

6 . The display device as claimed in claim 1 , further comprising a smart shelf removably attachable to the stand,
wherein the one or more processors are further configured to:
based on the smart shelf being attached to the stand, provide first partial power from the external power to the display as the first driving power, provide second partial power from the external power to the first battery as the charging power, and provide third partial power from the external power to the smart shelf,
wherein the smart shelf comprises:
a communication interface configured to perform communication with an external device, and
wherein the one or more processors are further configured to:
provide the third partial power to the communication interface, and
based on an image signal being received from the external device through the communication interface, transmit the image signal to the display.

7 . The display device as claimed in claim 6 , wherein the smart shelf further comprises:
a second battery, and wherein the one or more processors are further configured to provide a portion of the third partial power to the communication interface, and provide a another portion of the third partial power to the second battery as charging power.

8 . The display device as claimed in claim 7 , wherein the one or more processors are further configured to:
separate the second partial power and the third partial power from the external power such that the charging power of the first battery is greater than the charging power of the second battery, based on a feedback signal indicating that the first battery is charged being received from the charging and discharging circuit, re-separate the second partial power and the third partial power from the external power, and provide a portion of the re-separated third partial power to the communication interface, and provide another portion to the second battery as the charging power.

9 . The display device as claimed in claim 6 , wherein the smart shelf further comprises:
a wireless power transmission module, and wherein the one or more processors are further configured to:
provide a portion of the third partial power to the communication interface, and
based on the external device being located on the smart shelf, transmit another portion of the third partial power to the external device through the wireless power transmission module.

10 . The display device as claimed in claim 7 , wherein the one or more processors are further configured to:
based on the external power not being received from the power circuit, automatically switch to the battery priority use mode, and provide output power of the first battery to the display as the second driving power, and based on a feedback signal indicating that the first battery is discharged being received from the charging and discharging circuit, provide output power of the second battery to the display as third driving power.

11 . The display device as claimed in claim 6 , wherein the smart shelf is horizontal to a floor on which the display device is located.

12 . The display device as claimed in claim 6 , wherein the stand further comprises:
a driver configured to move the smart shelf, wherein the one or more processors are further configured to:
based on the display being in the landscape mode, control the driver to move the smart shelf to be to a first location corresponding to the landscape mode on the stand, and
based on the display being in the portrait mode, control the driver to move the smart shelf to a second location corresponding to the portrait mode.

13 . A controlling method of a display device, the method comprising:
controlling a charging and discharging circuit to charge a first battery using external power received through a power circuit; based on a user command for turning on a display being received, providing a portion of the external power to the display as first driving power; controlling the charging and discharging circuit to provide another portion of the external power to the first battery as charging power; and providing output power of the first battery to the display as second driving power in a battery priority use mode by setting a second output voltage of the charging and discharging circuit to be greater than a first output voltage of the power circuit.
