FIG. 4 is a view illustrating an example of utilizing a remote control device according to an embodiment of the present disclosure.

FIG. 4(a) illustrates that a pointer 205 corresponding to the remote control device 200 is displayed on the display unit 180.

A user may move or rotate the remote control device 200 vertically or horizontally. The pointer 205 displayed on the display unit 180 of the display device 100 corresponds to a movement of the remote control device 200. Since the corresponding pointer 205 is moved and displayed according to a movement on a 3D space as show in the drawing, the remote control device 200 may be referred to as a spatial remote control device.

FIG. 4(b) illustrates that if a user moves the remote control device 200, the pointer 205 displayed on the display unit 180 of the display device 100 is moved to the left according to the movement of the remote control device 200.

Information on a movement of the remote control device 200 detected through a sensor of the remote control device 200 is transmitted to the display device 100. The display device 100 may calculate the coordinates of the pointer 205 from the information on the movement of the remote control device 200. The display device 100 may display the pointer 205 to match the calculated coordinates.

FIG. 4(c) illustrates that while a specific button in the remote control device 200 is pressed, a user moves the remote control device 200 away from the display unit 180. Thus, a selected region in the display unit 180 corresponding to the pointer 205 may be zoomed in and displayed in an enlarged size.

On the other hand, if a user moves the remote control device 200 close to the display unit 180, a selection area in the display unit 180 corresponding to the pointer 205 may be zoomed out and displayed in a reduced size.

On the other hand, if the remote control device 200 is moved away from the display unit 180, a selection area may be zoomed out and if the remote control device 200 is moved closer to the display unit 180, a selection area may be zoomed in.

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

Moreover, 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.

Furthermore, a pointer in this specification means an object displayed on the display unit 180 in response to an operation of the remote control device 200. Therefore, in addition to the arrow form displayed as the pointer 205 in the drawing, various forms of objects are possible. For example, the above concept includes a point, a cursor, a prompt, and a thick outline. Then, the pointer 205 may be displayed in correspondence to one point of a horizontal axis and a vertical axis on the display unit 180 and also may be displayed in correspondence to a plurality of points such as a line and a surface.

The power board primary side 191 may receive a power capacity corresponding to a required power capacity of a power board secondary side 193. For example, when the required power capacity of the power board secondary side 193 is 282 W, the power capacity of the power board primary side 191 may also be designed to be 282 W.

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

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

In addition, the power supply unit 190 may include a sound power supply unit 195 that supplies power required for 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 40 W (20 V, 2 A).

In addition, the power supply unit 190 may include a timing controller power supply unit 196 that supplies power required for 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 power capacity of 24 W (12 V, 2 A).

In addition, the power supply unit 190 may include a panel power supply unit 197 that supplies power required for the display panel 182. For example, the panel power supply unit 195 may supply power to the display panel 182. The panel power supply unit 195 may have a power capacity of 110 W (22 V, 2 A).

On the other hand, the power supply unit 190 may include a motor power supply unit 198 that supplies power required for 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 72 W (24 V, 3 A).

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

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 board and add parts. In addition, it is necessary to additionally configure a wafer and a cable dedicated to the motor. Due to this, there is a problem in that the cost increases. Therefore, there is a need for a method of supplying power to the motor 400 without adding a separate motor power supply unit 198.

FIG. 6 is a block diagram illustrating the power supply unit according to an embodiment of the present disclosure.

Referring to FIG. 6, unlike the power supply unit of FIG. 5, the power supply unit 190 may not include the motor power supply unit 198. Instead, the power supplied to the motor 400 may be supplied from the sound power supply unit 195 or the panel power supply unit 197.

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

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 parts such as wafers and cables dedicated to the motor can also be reduced. Therefore, the costs can be reduced.

However, since the motor 400 uses the power supplied to the audio output unit 185 or the display panel 182, it is necessary to perform an operation of controlling the power supplied to the audio output unit 185 or the display panel 182 when the driving of the motor 400 is required.

FIG. 7 is a flowchart for describing a motor control method according to an embodiment of the present disclosure.

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

On the other hand, the movement command for the display unit 180 may include at least one of commands for rotating, folding, rolling, and moving the display unit 180.

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

The processor 170 may determine whether the motor driving power required for the motor 400 is secured in response to the received movement command.

In addition, the processor 170 may determine whether the motor driving power required from the start of the moving operation of the display unit 180 corresponding to the movement command to the completion of the moving operation of the display unit 180 is secured.

For example, when the movement command for the display unit 180 is a rotating command, the processor 170 may determine whether the motor driving power required from the start of the rotation of the display unit 180 to the completion of the rotation of the display unit 180 is secured.

In addition, the processor 170 may obtain 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.

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

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 secured, the processor 171 may control the motor 400 to perform and complete the moving operation of the display unit 180 (S703, S707).

The processor 170 may control the motor 400, which receives power from the sound power supply unit 195 or the panel power supply unit 197, to complete the moving operation of the display unit 180.

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 securing the motor driving power.

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 secure the motor driving power required for the motor 400.

The processor 170 may reduce the power usage rate 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 may secure the driving power required for the motor 400.

In addition, 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 secure the motor driving power required for the motor 400.

The processor 170 may reduce the power usage rate 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 may secure the driving power required for the motor 400.

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 moving operation of the display unit 180 (S707).

The processor 170 may control the motor 400, which receives power from the panel power supply unit 197, to perform and complete the moving operation of the display unit 180.

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

In addition, the processor 170 may change the image output setting information of the image source to the existing image output setting information (S708).

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 change. Therefore, the processor 170 may darkly output the image during the rotation of the display to secure the motor driving power, and may brightly output the image again when the rotation is completed.

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 change. Therefore, the processor 170 may output a small image during the rotation of the display to secure the motor driving power, and may output a large image again when the rotation is completed.

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

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 rate of the audio output unit 185, thereby reducing power consumed by the speaker. In this case, the processor 170 may secure the driving power required for the motor 400.

In addition, for example, the processor 170 may set the sound setting of the image source to mute to minimize the power usage rate of the audio output unit 185. In this case, the processor 170 may maximally secure the driving power required for the motor 400.

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 reducing the power usage rate of the main power supply unit 194. For example, the processor 170 may lower the speed of a CPU or the like of the main board to reduce the power consumed by the main board of the control unit 170 so as to lower the power load and secure the motor driving power.

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 motor driving power by reducing the power usage rate of the timing controller power supply unit 196. For example, the processor 170 may reduce the power load by lowering the data transmission rate of the timing controller, thereby securing the motor driving power.

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

The processor 170 may control the motor 400, which receives power from the sound power supply unit 195, to complete the moving operation of the display unit 180.

The processor 170 may control the sound power supply unit 195 to supply power to the motor 400.

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

For example, the processor 170 may 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 may output a low sound during the rotation of the display to secure the motor driving power, and may output a high sound again when the rotation is completed.

On the other hand, in general, maximum motor driving power is required when the motor 400 starts driving, and low motor driving power is required while the motor 400 is driving. Therefore, the processor 170 may mute sound or output low sound when the display unit 180 starts moving, so as to secure the maximum power when the motor 400 starts driving, and may set the sound to be gradually increased during the movement of the display unit 180. Therefore, when the moving 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.

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).

The processor 170 may obtain 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 secured, based on the obtained image display power consumption and limit power consumption. In addition, when the processor 170 can secure 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 when the reproduction of the corresponding image reproduction section starts to the time when the reproduction ends.

In addition, when the motor driving power is not secured in a first predetermined image reproduction section, the processor 170 may determine whether motor driving power is secured in a second image reproduction section shifted by a predetermined time.

The processor 170 may obtain 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.

In addition, the processor 170 may obtain image display power consumption of the display panel 182 based on 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 image display power consumption may be lower as the ratio of the screen displayed in black on the image source is higher.

In addition, the processor 170 may obtain image display power consumption expected in the display panel 182, based on the image source from the expected driving start time when the driving of the motor 400 is expected to start to the expected driving end time when the driving of the motor 400 is ended.

For example, when the movement command for the display unit 180 is input at 15:32:01, the expected driving start time when the driving of the motor 400 is expected to start is 15:32:02, and the expected driving end time when the driving of the motor 400 is ended is 15:32:12, image display power consumption of the display panel 182 may be obtained based on the image source corresponding to the image reproduction section from 15:32:02, which is the expected driving start time, to 15:32:12, which is the expected driving end time. In this case, the processor 170 may obtain image display power consumption for the expected driving time of the motor. The processor 170 may determine whether the driving power of the motor is secured, based on the image display power consumption for the expected driving time of the motor.

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

The processor 170 may control the motor 400, which receives power from the panel power supply unit 197 for the expected driving time of the motor, to complete the moving operation of the display unit 180.

The processor 170 may control the panel power supply unit 197 to supply power to the motor 400 for the expected driving time of the motor.

For example, the moving 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.

Referring to FIG. 8, 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 supply unit 194, the speaker may receive power through the sound power supply unit 195, the timing controller (T-CON) may receive power through the timing controller power supply unit 196, the panel may receive power through the panel power supply unit 197, and the motor may receive power through the panel power supply unit 197 or the sound power supply unit 195.

On the other hand, the processor 170 may receive the movement command for the display unit 180 through the user input interface unit 150.

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

The processor 170 may determine whether the motor driving power required for the motor 400 is secured 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 40 W and the limit power consumption is 180 W, the processor 170 may determine that the driving power required for the motor 400 is not secured.

The processor 170 may secure the motor driving power by changing the image output setting information to reduce the power usage rate of the panel.

For example, the processor 170 may set the image brightness setting to be dark to reduce the power usage rate of the panel from 80% to 40%, thereby reducing the power consumption of the panel. In this case, the processor 170 may secure the driving power of 40 W required for the motor 400.

In addition, when the motor driving power is secured, the processor 170 may control the motor 400 to complete the moving operation of the display unit 180.

In addition, the processor 170 may change the image output setting information to the existing image output setting information after completing the moving operation of the display unit 180.

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

Referring to 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 supply unit 194, the speaker may receive power through the sound power supply unit 195, the timing controller (T-CON) may receive power through the timing controller power supply unit 196, the panel may receive power through the panel power supply unit 197, and the motor may receive power through the panel power supply unit 197 or the sound power supply unit 195.

On the other hand, the processor 170 may receive the movement command for the display unit 180 through the user input interface unit 150.

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

The processor 170 may secure the motor driving power by changing the image output setting information to reduce the power usage rate of the panel.

For example, the processor 170 may set the image size setting to be small to reduce the power usage rate of the panel from 80% to 50%, thereby reducing the power consumption of the panel. In this case, the processor 170 may secure the driving power of 40 W required for the motor 400.

In addition, when the motor driving power is secured, the processor 170 may control the motor 400 to complete the moving operation of the display unit 180.

In addition, the processor 170 may change the image output setting information to the existing image output setting information after completing the moving operation of the display unit 180.

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.

Referring to FIG. 10, 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 supply unit 194, the speaker may receive power through the sound power supply unit 195, the timing controller (T-CON) may receive power through the timing controller power supply unit 196, the panel may receive power through the panel power supply unit 197, and the motor may receive power through the panel power supply unit 197 or the sound power supply unit 195.

On the other hand, the processor 170 may receive the movement command for the display unit 180 through the user input interface unit 150.

On the other hand, the processor 170 may lower the power usage rate of the panel by changing the image output setting information without determining whether the motor driving power is secured.

For example, when the processor 170 receives the movement command, the processor 170 may change the image size setting to be reduced to a preset image size and change the image brightness setting to be reduced to a preset brightness. In this case, it is possible to secure the power of 65 W, which is more than the required motor driving power of 40 W.

In addition, the processor 170 may control the motor 400 to complete the moving operation of the display unit 180.

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

In addition, the processor 170 may change the image output setting information to the existing image output setting information after completing the moving operation of the display unit 180.

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

Referring to 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 supply unit 194, the speaker may receive power through the sound power supply unit 195, the timing controller (T-CON) may receive power through the timing controller power supply unit 196, the panel may receive power through the panel power supply unit 197, and the motor may receive power through the panel power supply unit 197 or the sound power supply unit 195.

On the other hand, the processor 170 may receive the movement command for the display unit 180 through the user input interface unit 150.

On the other hand, the processor 170 may determine whether the motor driving power is secured.

For example, the processor 170 may obtain image display power consumption expected in the display panel 182, based on the image source from the expected driving start time when the driving of the motor 400 is expected to start to the expected driving end time when the driving of the motor 400 is ended. In this case, the processor 170 may obtain image display power consumption for the expected driving time of the motor 40. In addition, the processor 170 may determine whether the driving power of the motor is secured, based on the image display power consumption, the total power consumption, and the required motor driving power for the expected driving time of the motor.

For example, when the movement command for the display unit 180 is input at 15:32:01, the expected driving start time when the driving of the motor 400 is expected to start is 15:32:02, and the expected driving end time when the driving of the motor 400 is ended is 15:32:12, expected image display power consumption expected to be consumed by the display panel 182 may be obtained based on the image source from 15:32:02, which is the expected driving start time, to 15:32:12, which is the expected driving end time. In this case, the processor 170 may obtain image display power consumption for the expected driving time of the motor.

Referring to FIG. 11, as a dark area increases in the image source from the expected driving start time to the expected driving end time, the power usage rate of the panel may be lowered from 70% to 30%. The processor 170 may determine that the expected total power consumption is 165 W, which is less than the limit power consumption, even when the motor is operated for the expected driving time. The processor 170 may determine that the motor driving power is secured, and may supply power to the motor 400 through the panel power supply unit 197 at the expected driving start time to complete the moving operation of the display unit 180.

On the other hand, when the processor 170 determines that the motor driving power is not secured for 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 image display power consumption for the shifted expected driving time.

For example, when the shifted expected driving start time is 15:33:02 and the shifted expected driving end time is 15:33:12, expected image display power consumption expected to be consumed by the display panel 182 may be obtained based on the image source from 15:33:02, which is the expected driving start time, to 15:33:12, which is the expected driving end time.

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 moving operation of the display unit 180 by supplying power to the motor at the shifted expected driving start time.
