[0099] Next, describe Figure 4 .

[0100] Figure 4 It is a view showing an example of using the remote control device according to an embodiment of the present disclosure.

[0101] Figure 4 (a) shows that the indicator 205 corresponding to the remote control device 200 is displayed on the display unit 180 .

[0102] The user can vertically or horizontally move or rotate the remote control device 200. The indicator 205 displayed on the display unit 180 of the display device 100 corresponds to the movement of the remote control device 200. Since the corresponding indicator 205 is moved and displayed according to the movement on the 3D space as shown in the figure, the remote control device 200 may be referred to as a spatial remote control device.

[0103] Figure 4 (b) shows that if the user moves the remote controlling apparatus 200 , the pointer 205 displayed on the display unit 180 of the display apparatus 100 moves to the left according to the movement of the remote controlling apparatus 200 .

[0104] Information about the movement of the remote control apparatus 200 detected by the sensor of the remote control apparatus 200 is transmitted to the display apparatus 100. The display apparatus 100 may calculate the coordinates of the pointer 205 from the information about the movement of the remote control apparatus 200. The display apparatus 100 may display the pointer 205 to match the calculated coordinates.

[0105] Figure 4 (c) shows that while pressing a specific button in the remote control apparatus 200, the user moves the remote control apparatus 200 away from the display unit 180. Therefore, a selection area corresponding to the pointer 205 in the display unit 180 may be enlarged and displayed in an enlarged size.

[0106] On the other hand, if the user moves the remote control apparatus 200 closer to the display unit 180 , a selection area corresponding to the pointer 205 in the display unit 180 may be reduced and displayed in a reduced size.

[0107] On the other hand, if the remote control apparatus 200 moves away from the display unit 180 , the selection area may be reduced, and if the remote control apparatus 200 moves close to the display unit 180 , the selection area may be enlarged.

[0108] Additionally, if a specific button in the remote control device 200 is pressed, recognition of vertical or horizontal movement may be excluded. That is, if the remote control device 200 moves away from or close to the display unit 180, up, down, left, or right movement may not be recognized, and only back and forth movement may be recognized. When a specific button in the remote control device 200 is not pressed, the indicator 205 is moved only according to the up, down, left, or right movement of the remote control device 200.

[0109] Furthermore, the moving speed or moving direction of the pointer 205 may correspond to the moving speed or moving direction of the remote control device 200 .

[0110] In addition, the indicator in this specification means an object displayed on the display unit 180 in response to the operation of the remote control device 200. Therefore, in addition to the arrow form shown as the indicator 205 in the drawings, various forms of objects are possible. For example, the above concept includes a point, a cursor, a prompt, and a thick outline. Subsequently, the indicator 205 can be displayed corresponding to one point in the horizontal axis and the vertical axis on the display unit 180, and can also be displayed corresponding to multiple points such as a line and a surface.

[0111] The control unit 170 may also be referred to as a processor 170. In addition, the storage unit 140 may be referred to as a memory 140. In addition, the wireless communication unit 173 may be referred to as a communication interface 173.

[0112] The display unit 180 may include a timing controller (T-CON) 181 used in a conventional display technology, and may include a display panel 182. When the display panel 182 is an organic light emitting diode (OLED), a high potential power (EVDD) may be supplied, and when the display panel 182 is a liquid crystal display (LCD), a light source power voltage (VLED) may be supplied to a backlight unit (BLU).

[0113] On the other hand, the display device 100 may further include a motor 400 that provides power for the movement of the display unit 180. The movement of the display unit 180 may include a rotation, folding, winding or moving movement. That is, the display unit 180 may be rotated to be rotated left and right or tilted forward and backward in a horizontal mode and a vertical mode. The display unit 180 may be foldable. The display unit 180 may be rollable. In addition, the display unit 180 may be movable vertically or horizontally.

[0114] The rotating, folding, rolling, or moving motion of the display unit 180 may be achieved by using a conventional display technology using the power source of the motor 400 .

[0115] On the other hand, when the motor 400 supplies power for the movement of the display unit 180 , the power supply unit 190 must be able to supply power to the motor 400 .

[0116] Figure 5 is a block diagram showing a power supply unit according to an embodiment of the related art.

[0117] The power supply unit 190 may receive power from the external power source 300. The external power source 300 may supply AC power and may have a voltage range of 100V to 240V.

[0118] On the other hand, the power supply unit 190 may include a power board primary side 191. The power board primary side 191 may receive power from the external power source 300. The power board primary side 191 may receive a power capacity corresponding to a required power capacity of the power board secondary side 193. For example, when the required power capacity of the power board secondary side 193 is 282W, the power capacity of the power board primary side 191 may also be designed to be 282W.

[0119] On the other hand, the power supply unit 190 may include a transformer 192. The transformer 192 may distribute and output power of the power board primary side 191 to the power board secondary side 193.

[0120] On the other hand, the power supply unit 190 may include a main power supply unit 194 that supplies power required by the control unit 170. For example, the main power supply unit 194 may supply power to a main board of the control unit 170. The main power supply unit 194 may have a power capacity of 36W (12V, 3A).

[0121] In addition, the power supply unit 190 may include a sound power supply unit 195 that supplies power required by the audio output unit 185. For example, the sound power supply unit 195 may supply power to a speaker of the audio output unit 185. The sound power supply unit 195 may have a power capacity of 40W (20V, 2A).

[0122] In addition, the power supply unit 190 may include a timing controller power supply unit 196 that supplies power required by the timing controller (T-CON) 181. For example, the timing controller power supply unit 196 may supply power to the timing controller 181 of the display unit 180. The timing controller power supply unit 196 may have a 24W

[0123] (12V, 2A) power capacity.

[0124] In addition, the power supply unit 190 may include a panel power supply unit 197 that supplies power required by the display panel 182. For example, the panel power supply unit 197 may supply power to the display panel 182. The panel power supply unit 197 may have a power capacity of 110 W (22 V, 2 A).

[0125] On the other hand, the power supply unit 190 may include a motor power supply unit 198 that supplies power required by the motor 400. For example, the motor power supply unit 198 may supply power to the motor 400. The motor power supply unit 198 may have a power capacity of 72W (24V, 3A).

[0126] In this case, the required power capacity of the power board secondary side 193 may be 282W in total, and the power capacity of the power board primary side 191 may also be designed to be 282W.

[0127] However, when a separate motor power supply unit 198 is designed to supply power to the motor 400, it is necessary to increase the design capacity of the power supply board and add components. In addition, it is necessary to additionally configure a chip and a cable dedicated to the motor. Therefore, there is a problem of increased cost. Therefore, a method of supplying power to the motor 400 without adding a separate motor power supply unit 198 is needed.

[0128] Figure 6 FIG. 4 is a block diagram showing a power supply unit according to an embodiment of the present disclosure.

[0129] Reference Figure 6 ,and Figure 5 Unlike the power supply unit of FIG. 1 , the power supply unit 190 may not include the motor power supply unit 198. Alternatively, the power supplied to the motor 400 may be supplied from the sound power supply unit 195 or the panel power supply unit 197.

[0130] In this case, the required power capacity of the power board secondary side 193 may be 210W in total, and the power capacity of the power board primary side 191 may also be designed to be 210W.

[0131] Therefore, the power board design capacity can be reduced by the power capacity required to drive the motor 400, the PCB size of the power board can be reduced, and the input of components such as a chip and a cable dedicated to the motor can also be reduced. Therefore, the cost can be reduced.

[0132] However, since the motor 400 uses the power supplied to the audio output unit 185 or the display panel 182 , when the motor 400 needs to be driven, an operation of controlling the power supplied to the audio output unit 185 or the display panel 182 needs to be performed.

[0133] Figure 7 is a flowchart for describing a motor control method according to an embodiment of the present disclosure.

[0134] The processor 170 may receive a motion command for the display unit 180 ( S701 ). For example, the processor 170 may receive a motion command for the display unit 180 through the user input interface unit 150 .

[0135] On the other hand, the motion command for the display unit 180 may include at least one of a command for rotating, folding, rolling, and moving the display unit 180 .

[0136] The processor 170 may determine whether the motor driving power required by the motor 400 that provides power for the movement of the display unit 180 is secured (S702).

[0137] The processor 170 may determine whether the motor driving power required by the motor 400 is ensured in response to the received motion command.

[0138] Furthermore, the processor 170 may determine whether required motor driving power is secured from the start of the motion operation of the display unit 180 corresponding to the motion command to the completion of the motion operation of the display unit 180 .

[0139] For example, when the motion command for the display unit 180 is a rotation command, the processor 170 may determine whether required motor driving power is ensured from the start of rotation of the display unit 180 to the completion of rotation of the display unit 180 .

[0140] In addition, the processor 170 may obtain the current total power consumption of the display device 100 based on the power usage rates of the control unit 170 , the audio output unit 185 , the timing controller 181 , the display panel 182 , and the motor 400 .

[0141] In addition, the processor 170 may determine whether the motor driving power is ensured based on whether the sum of the current total power consumption and the required motor driving power exceeds the limit power consumption. The limit power consumption may refer to the total power consumption that can ensure stability based on the power design capacity of the power board.

[0142] On the other hand, when the processor 170 determines that the motor driving power required to complete the movement of the display unit 180 is ensured, the processor 171 may control the motor 400 to perform and complete the movement operation of the display unit 180 ( S703 , S707 ).

[0143] The processor 170 may control the motor 400 receiving power from the sound power supply unit 195 or the panel power supply unit 197 to perform a movement operation of the display unit 180 .

[0144] On the other hand, when the motor driving power required to complete the movement of the display unit 180 is not secured, the processor 170 may secure the motor driving power by changing the image output setting information of the image source (S704).

[0145] The processor 170 may change the image output setting information to reduce the power usage rate of the display panel 182 of the display unit 180 , thereby ensuring the motor driving power.

[0146] For example, the processor 170 may change the image output setting information by setting the image brightness setting of the image source to be darker than the existing image brightness setting, and may ensure the motor driving power required by the motor 400 .

[0147] The processor 170 can reduce the power usage of the panel by setting the image brightness setting to be darker than the existing image brightness setting, thereby reducing the power consumed by the panel. In this case, the processor 170 can ensure the driving power required by the motor 400.

[0148] Furthermore, for example, the processor 170 may change the image output setting information by setting the image size setting of the image source to be smaller than the existing image size setting, and may ensure the motor driving power required by the motor 400 .

[0149] The processor 170 can reduce the power usage of the panel by setting the image size setting to be smaller than the existing image size setting, thereby reducing the power consumed by the panel. In this case, the processor 170 can ensure the driving power required by the motor 400.

[0150] The processor 170 may secure the motor driving power by changing the image output setting information of the image source, and may control the motor 400 to complete the movement operation of the display unit 180 ( S707 ).

[0151] The processor 170 may control the motor 400 receiving power from the panel power supply unit 197 to perform and complete the movement operation of the display unit 180 .

[0152] The processor 170 may control the panel power supply unit 197 to supply power to the motor 400 .

[0153] Furthermore, the processor 170 may change the image output setting information of the image source to the existing image output setting information (S708).

[0154] For example, the processor 170 may change the image output setting information to the existing image output setting information by changing the image brightness setting to the existing image brightness setting before the change. Therefore, the processor 170 may output the image darkly during the display rotation to ensure the motor driving power, and may output the image brightly again when the rotation is completed.

[0155] For example, the processor 170 may change the image output setting information to the existing image output setting information by changing the image size setting to the existing image size setting before the change. Therefore, the processor 170 may output a small image during the display rotation to ensure the motor driving power, and may output a large image again when the rotation is completed.

[0156] On the other hand, when the motor driving power required to complete the movement of the display unit 180 is not secured, the processor 170 may secure the motor driving power by changing the image output setting information of the image source (S705).

[0157] The processor 170 may change the sound output setting information to reduce the power usage rate of the audio output unit 185, thereby ensuring the motor driving power.

[0158] For example, the processor 170 may set the sound setting of the image source to be lower than the existing sound setting to reduce the power usage of the audio output unit 185, thereby reducing the power consumed by the speaker. In this case, the processor 170 can ensure the driving power required by the motor 400.

[0159] In addition, for example, the processor 170 may set the sound setting of the image source to mute to minimize the power usage of the audio output unit 185. In this case, the processor 170 can maximize the driving power required by the motor 400.

[0160] On the other hand, when the motor driving power required to complete the movement of the display unit 180 is not ensured, the processor 170 can ensure the motor driving power by reducing the power usage of the main power supply unit 194. For example, the processor 170 can reduce the speed of the CPU on the main board, etc., to reduce the power consumed by the main board of the control unit 170, thereby reducing the power load and ensuring the motor driving power.

[0161] On the other hand, when the motor driving power required to complete the movement of the display unit 180 is not ensured, the processor 170 can ensure the motor driving power by reducing the power usage of the timing controller power supply unit 196. For example, the processor 170 can reduce the power load by reducing the data transfer rate of the timing controller, thereby ensuring the motor driving power.

[0162] The processor 170 can ensure the motor driving power by changing the sound output setting information of the image source, and can control the motor 400 to complete the movement operation of the display unit 180 (S707).

[0163] The processor 170 can control the motor 400 that receives power from the sound power supply unit 195 to complete the movement operation of the display unit 180.

[0164] The processor 170 can control the sound power supply unit 195 to supply power to the motor 400.

[0165] In addition, the processor 170 can change the sound output setting information of the image source to the existing sound output setting information (S709).

[0166] For example, the processor 170 can change the sound output setting information to the existing sound output setting information by changing the image sound setting to the existing image sound setting. Therefore, the processor 170 can output a small sound during the rotation of the display to ensure the motor driving power, and can output a large sound again when the rotation is completed.

[0167] On the other hand, generally, the maximum motor driving power is required when the motor 400 starts driving, and a low motor driving power is required when the motor 400 is driving. Therefore, the processor 170 may mute or output a small sound when the display unit 180 starts moving so as to ensure the maximum power when the motor 400 starts driving, and may set the sound to gradually increase during the movement of the display unit 180. Therefore, when the movement operation of the display unit 180 is completed, the image sound setting may be controlled so that the sound output setting information is naturally changed to the existing sound output setting information.

[0168] On the other hand, when the motor driving power required to complete the movement of the display unit 180 is not secured, the processor 170 may obtain an expected motor driving time for securing the motor driving power (S706).

[0169] The processor 170 may obtain the image display power consumption of the display panel 182 of the display unit 180 in a predetermined image reproduction section based on the image source displayed on the display unit 180. The processor 170 may determine whether the motor driving power is ensured and the power consumption is limited based on the obtained image display power consumption. In addition, when the processor 170 is able to ensure the motor driving power by reducing the image display power consumption in the predetermined image reproduction section, the processor 170 may obtain the expected motor driving time from the start of reproduction to the end of reproduction of the corresponding image reproduction section.

[0170] Furthermore, when the motor driving power is ensured in the first predetermined image reproduction section, the processor 170 may determine whether the motor driving power is ensured in the second image reproduction section shifted by the predetermined time.

[0171] The processor 170 may obtain the image display power consumption of the display panel 182 based on the image source displayed on the display unit 180. In addition, the processor 170 may determine whether the motor driving power is secured based on the image display power consumption.

[0172] In addition, the processor 170 may obtain the image display power consumption of the display panel 182 based on the brightness information of the image source displayed on the display unit 180. For example, when the display panel 182 is an organic light emitting diode panel, the higher the ratio of the screen displayed in black on the image source, the lower the image display power consumption may be.

[0173] Furthermore, the processor 170 may obtain expected image display power consumption in the display panel 182 based on the image source from an expected driving start time when driving of the motor 400 is expected to start to an expected driving end time when driving of the motor 400 ends.

[0174] For example, when a motion command for the display unit 180 is input at 15:32:01, when the expected drive start time when the motor 400 is expected to start is 15:32:02, and when the expected drive end time when the motor 400 is expected to end is 15:32:12, the image display power consumption of the display panel 182 can be obtained based on the image source corresponding to the image reproduction segment, which is from 15:32:02 as the expected drive start time to 15:32:12 as the expected drive end time. In this case, the processor 170 can obtain the image display power consumption within the expected drive time of the motor. The processor 170 can determine whether the driving power of the motor is ensured based on the image display power consumption within the expected drive time of the motor.

[0175] The processor 170 may obtain an expected motor driving time for securing the motor driving power, and may control the motor 400 to complete the movement operation of the display unit 180 within the expected motor driving time (S707).

[0176] The processor 170 may control the motor 400 receiving power from the panel power supply unit 197 to complete the movement operation of the display unit 180 within the expected driving time of the motor.

[0177] The processor 170 may control the panel power supply unit 197 to supply power to the motor 400 within the expected driving time of the motor.

[0178] For example, the movement operation of the display unit 180 may be completed by controlling the motor 400 from 15:32:02, which is the expected driving start time of the motor, to 15:32:12, which is the expected driving end time of the motor.

[0179] Figure 8 is a view for describing a motor control method for securing motor driving power by changing image output setting information of an image source according to an embodiment of the present disclosure.

[0180] Reference Figure 8 , the power usage rates of the main board, speaker, timing controller (T-CON), panel, and motor may be 70%, 30%, 60%, 80%, and 0%, respectively, and the total power consumption may be 180 W. In this case, the main board may receive power through the main power unit 194, the speaker may receive power through the sound power unit 195, the timing controller (T-CON) may receive power through the timing controller power unit 196, the panel may receive power through the panel power unit 197, and the motor may receive power through the panel power unit 197 or the sound power unit 195.

[0181] On the other hand, the processor 170 may receive a motion command for the display unit 180 through the user input interface unit 150 .

[0182] In addition, the processor 170 may determine whether the motor driving power required for the motor 400 that provides power for the movement of the display unit 180 is secured.

[0183] The processor 170 can determine whether the motor driving power required by the motor 400 is ensured by comparing the current total power consumption with the limit power consumption at which the maximum power can be used. For example, when the required motor driving power is 40W and the limit power consumption is 180W, the processor 170 can determine that the driving power required by the motor 400 is not ensured.

[0184] The processor 170 may ensure the motor driving power by changing the image output setting information to reduce the power usage of the panel.

[0185] For example, the processor 170 may set the image brightness setting to dark to reduce the power usage of the panel from 80% to 40%, thereby reducing the power consumption of the panel. In this case, the processor 170 may ensure the 40W driving power required by the motor 400.

[0186] In addition, when the motor driving power is ensured, the processor 170 may control the motor 400 to complete the movement operation of the display unit 180 .

[0187] For example, the processor 170 may supply 40 W of power to the motor 400 through the panel power supply unit 197 and operate the motor at a power usage rate of 100%, thereby completing the movement operation of the display unit 180 .

[0188] Furthermore, the processor 170 may change the image output setting information to the existing image output setting information after the motion operation of the display unit 180 is completed.

[0189] For example, the processor 170 may brightly change the image brightness setting to the existing brightness setting to increase the power usage of the panel from 40% to 80%, thereby increasing the power consumption of the panel.

[0190] Fig. 9 is a view for describing a motor control method for securing motor driving power by changing image output setting information of an image source according to an embodiment of the present disclosure.

[0191] Reference Fig. 9, the power usage rates of the main board, the speaker, the timing controller (T-CON), the panel, and the motor may be 70%, 30%, 60%, 80%, and 0%, respectively, and the total power consumption may be 180 W. In this case, the main board may receive power through the main power unit 194, the speaker may receive power through the sound power unit 195, the timing controller (T-CON) may receive power through the timing controller power unit 196, the panel may receive power through the panel power unit 197, and the motor may receive power through the panel power unit 197 or the sound power unit 195.

[0192] On the other hand, the processor 170 may receive a motion command for the display unit 180 through the user input interface unit 150 .

[0193] In addition, the processor 170 may determine whether the motor driving power required for the motor 400 that provides power for the movement of the display unit 180 is secured.

[0194] The processor 170 can determine whether the motor driving power required by the motor 400 is ensured by comparing the current total power consumption with the limit power consumption at which the maximum power can be used. For example, when the required motor driving power is 40W and the limit power consumption is 180W, the processor 170 can determine that the driving power required by the motor 400 is not ensured.

[0195] The processor 170 may ensure the motor driving power by changing the image output setting information to reduce the power usage of the panel.

[0196] For example, the processor 170 may set the image size setting to small to reduce the power usage of the panel from 80% to 50%, thereby reducing the power consumption of the panel. In this case, the processor 170 may ensure the 40W driving power required by the motor 400.

[0197] In addition, when the motor driving power is ensured, the processor 170 may control the motor 400 to complete the movement operation of the display unit 180 .

[0198] For example, the processor 170 may supply 40 W of power to the motor 400 through the panel power supply unit 197 and operate the motor at a power usage rate of 100%, thereby completing the movement operation of the display unit 180 .

[0199] Furthermore, the processor 170 may change the image output setting information to the existing image output setting information after the motion operation of the display unit 180 is completed.

[0200] For example, the processor 170 may greatly change the image size setting to the existing size setting to increase the power usage rate of the panel from 40% to 80%, thereby increasing the power consumption of the panel.

[0201] Fig.10 is a view for describing a motor control method for securing motor driving power by changing image output setting information of an image source according to an embodiment of the present disclosure.

[0202] Reference Fig.10 , refer to Fig.10 , the power usage rates of the main board, speaker, timing controller (T-CON), panel, and motor may be 70%, 30%, 60%, 80%, and 0%, respectively, and the total power consumption may be 180 W. In this case, the main board may receive power through the main power unit 194, the speaker may receive power through the sound power unit 195, the timing controller (T-CON) may receive power through the timing controller power unit 196, the panel may receive power through the panel power unit 197, and the motor may receive power through the panel power unit 197 or the sound power unit 195.

[0203] On the other hand, the processor 170 may receive a motion command for the display unit 180 through the user input interface unit 150 .

[0204] On the other hand, the processor 170 may reduce the power usage rate of the panel by changing the image output setting information without determining whether the motor driving power is ensured.

[0205] For example, when processor 170 receives a motion command, processor 170 may change the image size setting to reduce it to a preset image size, and change the image brightness setting to reduce it to a preset brightness. In this case, a power of 65W may be ensured, which is greater than the required motor drive power of 40W.

[0206] In addition, the processor 170 may control the motor 400 to perform a movement operation of the display unit 180 .

[0207] For example, the processor 170 may supply 40W of power to the motor 400 through the panel power supply unit 197 and operate the motor at 100% power usage, thereby completing the motion operation of the display unit 180. In this case, 165W of power less than the limit power consumption of 180W may be consumed.

[0208] Furthermore, the processor 170 may change the image output setting information to the existing image output setting information after the motion operation of the display unit 180 is completed.

[0209] For example, the processor 170 may greatly change the image size setting to the existing size setting and brightly set the image brightness setting to the existing image brightness setting to increase the power usage of the panel from 30% to 80%, thereby increasing the power consumption of the panel.

[0210] Fig.11 1 is a diagram for describing a motor control method for securing motor driving power by waiting until an image section in which driving power can be secured according to an embodiment of the present disclosure.

[0211] Reference Fig.11 , the power usage rates of the main board, the speaker, the timing controller (T-CON), the panel, and the motor may be 70%, 30%, 60%, 70%, and 0%, respectively, and the total power consumption may be 165 W. In this case, the main board may receive power through the main power unit 194, the speaker may receive power through the sound power unit 195, the timing controller (T-CON) may receive power through the timing controller power unit 196, the panel may receive power through the panel power unit 197, and the motor may receive power through the panel power unit 197 or the sound power unit 195.

[0212] On the other hand, the processor 170 may receive a motion command for the display unit 180 through the user input interface unit 150 .

[0213] On the other hand, the processor 170 may determine whether the motor driving power is ensured.

[0214] For example, the processor 170 may obtain an image source based on an expected drive start time when the drive of the motor 400 is expected to start to an expected drive end time when the drive of the motor 400 ends, and obtain the expected image display power consumption in the display panel 182. In this case, the processor 170 may obtain the image display power consumption for the expected drive time of the motor 40. In addition, the processor 170 may determine whether the driving power of the motor is ensured based on the image display power consumption, the total power consumption, and the required motor driving power within the expected drive time of the motor.

[0215] For example, when a motion command for the display unit 180 is input at 15:32:01, the expected driving start time when the motor 400 is expected to start driving is 15:32:02, and the expected driving end time when the motor 400 is expected to end driving is 15:32:12, the image display power consumption of the display panel 182 can be obtained based on the image source corresponding to the image reproduction section, which is from 15:32:02 as the expected driving start time to 15:32:12 as the expected driving end time. In this case, the processor 170 can obtain the image display power consumption during the expected driving time of the motor.

[0216] Reference Fig.11 , as the dark area in the image source from the expected drive start time to the expected drive end time increases, the power usage of the panel can be reduced from 70% to 30%. The processor 170 can determine that even when the motor operates within the expected drive time, the expected total power consumption is 165W (which is less than the limit power consumption). The processor 170 can determine that the motor drive power is ensured, and can supply power to the motor 400 through the panel power supply unit 197 at the expected drive start time to complete the motion operation of the display unit 180.

[0217] On the other hand, when the processor 170 determines that the motor driving power is not secured within the expected driving time of the motor, the processor 170 may shift the expected driving time by a predetermined time. The processor 170 may obtain the image display power consumption within the shifted expected driving time.

[0218] For example, when the migrated expected driving start time is 15:33:02 and the migrated expected driving end time is 15:33:12, the expected image display power consumption expected to be consumed by the display panel 182 can be obtained based on the image source from 15:33:02 as the expected driving start time to 15:33:12 as the expected driving end time.

[0219] The processor 170 may determine whether the motor driving power is secured based on the expected image display power consumption. When the motor driving power is secured, the processor 170 may complete the motion operation of the display unit 180 by supplying power to the motor at the shifted expected driving start time.
