A plurality of microphones (290) may be provided.

Next, Figure 4 is described.

Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

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

The user can move or rotate the remote control device (200) up and down, left and right. The pointer (205) displayed on the display (180) of the display device (100) corresponds to the movement of the remote control device (200). This remote control device (200) can be called a space remote control because, as shown in the drawing, the pointer (205) moves and is displayed according to the movement in 3D space.

Figure 4 (b) illustrates that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display (180) of the display device (100) also moves to the left correspondingly.

Information about the movement of the remote control device (200) detected through the sensor of the remote control device (200) is transmitted to the display device (100). The display device (100) can calculate the coordinates of the pointer (205) from the information about the movement of the remote control device (200). The display device (100) can display the pointer (205) to correspond to the calculated coordinates.

Figure 4 (c) illustrates a case where a user moves the remote control device (200) away from the display (180) while pressing a specific button within the remote control device (200). As a result, a selection area within the display (180) corresponding to the pointer (205) can be zoomed in and displayed in an enlarged manner.

Conversely, when the user moves the remote control device (200) closer to the display (180), the selection area within the display (180) corresponding to the pointer (205) may be zoomed out and displayed in a reduced size.

Meanwhile, when the remote control device (200) moves away from the display (180), the selection area may be zoomed out, and when the remote control device (200) moves closer to the display (180), the selection area may be zoomed in.

Additionally, when a specific button within the remote control device (200) is pressed, recognition of up, down, left, and right movements may be excluded. That is, when the remote control device (200) moves away from or toward the display (180), up, down, left, and right movements may not be recognized, and only forward and backward movements may be recognized. When a specific button within the remote control device (200) is not pressed, only the pointer (205) moves in accordance with the up, down, left, and right movements of the remote control device (200).

Meanwhile, the movement speed or movement direction of the pointer (205) can correspond to the movement speed or movement direction of the remote control device (200).

Meanwhile, the pointer in this specification refers to an object displayed on the display (180) in response to the operation of the remote control device (200). Accordingly, objects of various shapes other than the arrow shape illustrated in the drawing can be used as the pointer (205). For example, the pointer may be a concept including a point, a cursor, a prompt, a thick outline, etc. In addition, the pointer (205) may be displayed corresponding to one point on the horizontal or vertical axis on the display (180), or may be displayed corresponding to multiple points such as lines or surfaces.

The display device (100) can display the home menu immediately after receiving a power-on input. Alternatively, the display device (100) can display the home menu when receiving a home menu entry command.

Figure 5 is a drawing showing an example of a home menu displayed by a display device.

Figure 5 may be a home menu displayed by the controller (170) in normal mode. Normal mode may be the basic operation mode of the display device (100).

The home menu may include multiple items. The home menu may include items corresponding to each of the various functions provided by the display device (100). Recently, as the functions provided by the display device (100) have diversified, the number of items included in the home menu has been increasing.

The controller (170) can display an icon corresponding to each of a plurality of items. When the controller (170) receives a user input selecting an icon, it can provide the function of the item corresponding to the selected icon.

When the controller (170) displays the home menu in normal mode, it can display icons corresponding to each item included in the home menu as normal icons.

General icons may be icons that allow users to intuitively understand the functions provided by each item, regardless of the power consumption of the display device (100). Therefore, general icons are often displayed in color or dynamic images.

However, users may not utilize all functions of the display device (100). If icons corresponding to items not utilized by the user are displayed in color or dynamic images, unnecessary usage of a System On Chip (SoC), such as a controller (170), may be required. Consequently, power consumption of the display device (100) may be wasted.

Accordingly, the controller (170) can control the operating state of the display device (100) to a power saving mode to reduce power consumption. The power saving mode may be an operating mode for reducing power consumption of the display device (100).

When the controller (170) displays the home menu in power saving mode, it can display an icon corresponding to each item included in the home menu as a power saving icon.

The power saving icon may be an icon displayed in power saving mode. The power saving icon may be an icon displayed to minimize power consumption of the display device (100).

Previously, when the controller (170) displayed the home menu in power saving mode, all icons of items included in the home menu were displayed in black and white. For example, all power saving icons were displayed as static images with a black background and white text.

As the area displayed in black and white on the display (180) increases, the number of pixels that are turned off among the pixels for expressing colors on the display (180), such as OLED, may increase. Accordingly, the power consumption of the display (180) may be reduced.

However, if all the items included in the home menu are displayed in black and white, readability is reduced, making it difficult for users to recognize the functions provided by each item.

Meanwhile, items included in the home menu may be categorized by type. For example, items included in the home menu may be categorized into video items and service items. Video items may be items related to video content. Service items may be items related to various services or functions provided by the display device (100).

According to one embodiment of the present disclosure, when a display device (100) displays a home menu in power saving mode, it is intended to display a power saving icon corresponding to each of a plurality of items included in the home menu differently.

In relation to this, it is explained with reference to FIGS. 6 and 7.

FIG. 6 is a diagram illustrating an example of a home menu displayed by a display device in power saving mode according to an embodiment of the present disclosure.

The controller (170) can display the home menu in dark mode during power saving mode, as illustrated in the example of FIG. 6. Dark mode may be a mode in which the background of the home menu is displayed in black. However, this is merely an example, and the background of the home menu may be displayed in a color with low brightness, in addition to black, within a range where power consumption can be reduced.

The types of items included in the home menu can be divided into video items and service items.

The icon (310) corresponding to a video item may include an advertisement video icon (311) for providing an advertisement video. In addition, the icon (310) corresponding to a video item may include a recommended video icon (312) for providing a recommended video. However, this is merely an example, and the icon (310) corresponding to a video item may include various icons for providing video content.

An icon (310) corresponding to a video item may be displayed as a portion of the content corresponding to the video item. Some portions of the content may be dynamic video. Alternatively, some portions of the content may be still video.

Additionally, the icon (310) corresponding to the video item may be displayed as a poster of the content corresponding to the video item. However, this is merely an example, and the icon (310) corresponding to the video item may be displayed as a variety of images representing the content corresponding to the video item.

The icon (320) corresponding to the service item may be displayed in various ways depending on the function or type of each service item.

Icons (320) corresponding to service items may include a location and weather icon (321), a login icon (322), a search icon (323), a recent viewing information icon (324), and an application icon (325).

The location and weather icon (321) may be displayed as text or an image indicating the location and weather.

The login icon (322) may be displayed with a message requesting login, such as 'Please log in.'

The search icon (323) may be displayed as an image shaped like a magnifying glass.

The recently viewed icon (324) may be displayed to include text such as the title of the recently viewed channel or content.

The application icon (325) may be displayed as text or a preset representative image representing the name of each application installed on the display device (100).

When the controller (170) displays the home menu in power saving mode, it can display an icon (320) corresponding to a service item as a power saving icon.

For example, the controller (170) may display an icon (320) corresponding to a service item in black and white. The controller (170) may display the background of the icon (320) corresponding to the service item in black, and display the text included in the icon (320) corresponding to the service item in white.

Even if an icon (320) corresponding to a service item is displayed in black and white, the user can easily recognize the function provided by the icon. For example, even if an application icon (325) is displayed in black and white and only the text indicating the application name is visible, the user can easily identify which application the icon corresponds to.

When the controller (170) displays the home menu in power saving mode, it can display an icon (310) corresponding to the image item as a power saving icon.

The controller (170) can display an icon (310) corresponding to an image item in color.

Accordingly, the power consumption of the display device (100) can be reduced, while allowing the user to easily grasp the general content or atmosphere of the content corresponding to the icon (310).

Additionally, the controller (170) can display an icon (310) corresponding to an image item as a still image. Accordingly, the SoC's computational load can be reduced compared to when the controller (170) displays an icon (310) corresponding to an image item as a dynamic image. Accordingly, the power consumption of the display device (100) can be saved.

According to an embodiment, the controller (170) may display an icon (310) corresponding to a video item with only text related to the content, such as the title of the content. Accordingly, the power consumption reduction effect can be maximized.

Meanwhile, the display (180) of the display device (100) according to one embodiment of the present disclosure may be a transparent display.

The transparent display can be either a projection display type or a transmissive display type.

Projection display type may be a type that uses technology to display images by projecting light onto a transparent screen.

A transmissive display type may be one that uses technology to change the transmittance of the material itself, such as an OLED that emits light.

The transparent display may include an OLED panel in which each pixel contains an organic light-emitting diode (OLED). That is, the transparent display may be of the transmissive display type.

The transparency of the transparent display can be adjusted to any value between 0 and 100. The minimum transparency value can be 0. Additionally, the maximum transparency value can be 100. However, this transparency range is merely an example and may vary depending on the embodiment.

Meanwhile, the larger the area of a transparent display with non-zero transparency, the more power consumption can be reduced. Furthermore, the higher the transparency of a transparent display, the more power consumption can be reduced.

Accordingly, the present disclosure seeks to provide a display device (100) that operates in a transparent mode during a power saving mode to minimize power consumption.

FIG. 7 is a diagram illustrating an example of a display device displaying a home menu in a power saving mode according to an embodiment of the present disclosure.

The display (180) of Fig. 7 may be a transparent display.

The controller (170) can display the home menu in a transparent mode during power saving mode, as illustrated in the example of FIG. 7. The transparent mode may be a mode in which the transparency of the background of the home menu is adjusted to the maximum value. However, this is merely an example, and the transparency of the background of the home menu may be adjusted to a different value within a range in which power consumption can be reduced.

When the controller (170) displays the home menu in power saving mode, it can display an icon (320) corresponding to a service item as a power saving icon.

For example, the controller (170) can adjust the transparency of an icon (320) corresponding to a service item. The controller (170) can adjust the transparency of the icon (320) corresponding to the service item to be higher than the transparency of the icon (310) corresponding to the image item.

Additionally, the controller (170) can adjust the transparency of the background of an icon (320) corresponding to a service item to the maximum value and the transparency of the text to the minimum value.

Alternatively, the controller (170) may adjust the transparency of the background of the icon (320) corresponding to the service item to a first value, and adjust the transparency of the text included in the icon (320) corresponding to the service item to a second value lower than the first value.

Even if the transparency of an icon (320) corresponding to a service item is adjusted, the user can easily recognize the function corresponding to the icon. For example, even if the transparency of an application icon (325) is adjusted so that only the text indicating the application name is visible, the user can easily identify which application the icon corresponds to.

The controller (170) can display the color of the text included in the icon (320) corresponding to the service item as black.

Additionally, the controller (170) can adjust and display the color of the text included in the icon (320) corresponding to the service item.

As the display device (100) operates in transparent mode, some areas in front of the display (180) may be transparent and visible. Therefore, it may be difficult for a user to identify text included in an icon (320) corresponding to a service item depending on the color of an object or wall placed behind the display (180).

Accordingly, the controller (170) can adjust the color of the text and display it based on an image captured from the rear of the display (180).

For example, the controller (170) can capture the rear of the display (180) using a camera (not shown). The controller (170) can extract the average color of the captured image. Next, the controller (170) can display the text included in the icon (320) corresponding to the service item in a complementary color of the average color.

Accordingly, the controller (170) can enable the user to easily recognize the function of the service item regardless of the color of the object or wall placed behind the transparent display.

When the controller (170) displays the home menu in power saving mode, it can display an icon (310) corresponding to the image item as a power saving icon.

The controller (170) can adjust the transparency of an icon (310) corresponding to an image item.

For example, the controller (170) can adjust the transparency of an icon (310) corresponding to an image item to a minimum value.

Alternatively, the controller (170) may adjust the transparency of the icon (310) corresponding to the image item to a third value lower than the first value.

Accordingly, the user can clearly see the icon (310) corresponding to the video item and easily grasp the general content or atmosphere of the content corresponding to the icon (310).

Additionally, the controller (170) can display an icon (310) corresponding to an image item as a still image. The controller (170) can display an icon (310) corresponding to an image item in color. The controller (170) can display an icon (310) corresponding to an image item only with text related to the content, such as the title of the content.

According to an embodiment, the transparency of the icon (310) corresponding to the background and service items of the home menu may have a maximum value. Accordingly, the area of the area with the maximum transparency value may be maximized, thereby minimizing power consumption.

According to an embodiment, the transparency of at least one of the icons (310) corresponding to the background and service items of the home menu may have a value different from the maximum value.

For example, the controller (170) can adjust the transparency of the background of the home menu to the maximum value and adjust the transparency of the icon (310) corresponding to the service item to a value lower than the maximum value and higher than the minimum value.

Accordingly, compared to the case where the transparency of the icon (320) corresponding to the service item is adjusted to the maximum value, it is possible to make it easier for the user to recognize the function provided by the service item.

To summarize FIGS. 6 and 7, when a display device (100) according to one embodiment of the present disclosure displays a home menu in power saving mode, each icon (300) corresponding to an item can be displayed differently based on the type of item included in the home menu.

Next, with reference to FIGS. 8 and 9, a method for displaying icons for each item included in a home menu in different ways based on usage information by a display device (100) according to an embodiment of the present disclosure will be described.

FIG. 8 is a drawing showing an example of a home menu displayed by a display device in a normal mode according to an embodiment of the present disclosure.

The home menu can be displayed in various ways. The home menu (183) can be displayed in a portion of the display (180), as illustrated in FIG. 8. Alternatively, the home menu can be displayed in the entire display (180), as illustrated in FIG. 7.

When the home menu (183) is displayed in a portion of the display (180), a background screen (181) and a background screen list (182) may be displayed in the remaining portion of the display (180).

FIG. 9 is a diagram illustrating an example of a home menu that appears in a power saving mode of a display device according to an embodiment of the present disclosure.

The controller (170) can display the background screen (181) and the background screen list (182) in black in power saving mode. Alternatively, the controller (170) can adjust the transparency of the background screen (181) and the background screen list (182) to the maximum value in power saving mode.

The background screen (181) and the background screen list (182) may not be screens for providing information or functions. Therefore, the controller (170) may display the background screen (181) and the background screen list (182) in black or adjust the transparency to the maximum value to reduce power consumption.

Meanwhile, the controller (170) can display an icon corresponding to each item included in the home menu (183) as a power saving icon in power saving mode.

Items included in the home menu (183) can be divided into preferred items and general items.

Preference items can be items that a user prefers or is expected to prefer. Preference items can also be items that provide features that the user frequently uses.

General items may be items other than preferred items.

The method by which the controller (170) displays an icon (340) corresponding to a general item in power saving mode may be the same as the method of displaying an icon (320) corresponding to a service item described in FIGS. 6 to 7.

The controller (170) can display icons (340) corresponding to general items in black and white in power saving mode. Alternatively, the controller (170) can display icons (340) corresponding to general items by adjusting the transparency thereof in power saving mode.

Meanwhile, the power saving icon of the icon (330) corresponding to the preferred item may be the same as the general icon displayed in the general mode.

Since the preferred items are items that are expected to be preferred by the user, the controller (170) can display the same icon (330) corresponding to the preferred items in both the normal mode and the power saving mode, so that the items can be easily recognized by the user even in the power saving mode.

For example, the controller (170) can display an icon (330) corresponding to a preferred item in the same color as in the normal mode.

Next, a method for the controller (170) to obtain a preferred item is described.

The controller (170) can obtain a preferred item based on at least one of the usage information and user setting information of the display device (100).

First, a method for the controller (170) to obtain preferred items based on usage information is described.

Usage information may include at least one of item-specific usage history and item-specific login information.

The usage history by item may include at least one of the name of the item for each function used, the time of use, the duration of use, and the number of uses.

The controller (170) can acquire items with a recent usage history as preferred items. Items with a recent usage history may be items whose usage history is stored between the current time and a predetermined period of time prior to the current time. The predetermined period of time may vary, such as one week or one month. Items with a recent usage history may be items that provide functions that the user actually uses.

According to an embodiment, the controller (170) may acquire items that have been used a preset number of times or more over a given period of time as preferred items. For example, the controller (170) may acquire items that have been used five or more times in a month as preferred items. Alternatively, the controller (170) may acquire items that have been used three or more times in a week as preferred items.

According to an embodiment, the controller (170) may acquire items whose usage time is longer than a preset usage time as preferred items.

The usage time may be the time the user uses the function of the corresponding item. For example, the controller (170) may select an item with a maximum usage time of 3 hours or more as a preferred item.

Alternatively, the usage time may be the average time a user uses the function of the item. For example, the controller (170) may select an item with an average usage time of 3 hours or more as a preferred item.

The more frequently or frequently an item is used, the more likely it is to be preferred by users.

Item-specific login information may include item-specific stored IDs and passwords.

The controller (170) can acquire an item in which login information is stored as a preferred item (330). The item in which login information is stored may be an item in which a user logs in by entering an ID and password to use the function of the item.

The controller (170) has the advantage of automatically acquiring the preferred item (330) by acquiring the preferred item (330) based on the usage information.

Meanwhile, the controller (170) can acquire preferred items (330) based on user-defined information. The user-defined information can include a list of items directly set as preferred items by the user. The user can set preferred items by entering the power-saving mode setting menu, etc. The controller (170) can acquire the items set as preferred items by the user as preferred items (330).

The controller (170) has the advantage of being able to clearly obtain the items that the user actually prefers by obtaining the items set as preferred items (330) by the user.

Meanwhile, when the controller (170) receives a command to enter the home menu while displaying video content, it can end the display of the content video and display the home menu in all or part of the display (180).

However, if you stop displaying the content video and display the home menu, unnecessary screen transitions may waste power.

Accordingly, when a display device (100) according to one embodiment of the present disclosure receives a home menu entry command while displaying a content image in power saving mode, it intends to display the home menu without ending the content image display.

Next, a detailed explanation will be given with reference to Fig. 10.

FIG. 10 is a diagram illustrating an example of a display device displaying content images and a home menu in a power saving mode according to an embodiment of the present disclosure.

The controller (170) can display the home menu when receiving a command to display the side bar (184) while displaying content video.

The command to display the sidebar (184) can be performed in the same manner as the command to enter the home menu. For example, the command to display the sidebar (184) can be a user input of pressing the home button (232).

Alternatively, the command to display the sidebar (184) may be performed in a different manner than the command to enter the home menu.

For example, a command to display a sidebar (184) may be an input of pressing the left button among the directional buttons twice in succession. When the controller (170) receives an input of pressing the left button twice in succession, it may slide the sidebar (184) from the right edge of the display (180) to the left to display it.

Accordingly, the display device (100) according to one embodiment of the present disclosure can operate by distinguishing between a case where the content image is terminated and the home menu is displayed, and a case where the content image is not terminated and the home menu is displayed in the form of a sidebar (184).

The controller (170) may display the home menu in the form of a sidebar (184). The sidebar (184) may appear in a rectangular shape on the side of the display (180), but is not limited thereto. The controller (170) may display the home menu in various positions, shapes, and sizes as long as it does not interfere with viewing of content.

Meanwhile, the controller (170) can determine the items included in the side bar (184) based on at least one of usage information and user setting information.

The controller (170) can obtain a preferred item based on at least one of usage information and user setting information.

For example, the controller (170) can obtain a preferred item and determine the preferred item as an item included in the side bar (184).

Alternatively, the controller (170) may determine that items that the user has directly set to be included in the sidebar (184) are items to be included in the sidebar (184).

Additionally, there may be various ways in which the controller (170) determines what items are included in the sidebar (184).

Meanwhile, the operation mode of the display device (100) according to one embodiment of the present disclosure can be controlled to a power saving mode based on user input.

FIG. 11 is a flowchart illustrating an operation in which a display device according to one embodiment of the present disclosure is controlled into a power saving mode based on a user input.

The controller (170) can enter the power saving mode setting menu (S10).

The controller (170) can enter the power saving mode setting menu based on user input.

The power saving mode settings menu may be a menu for changing the overall settings related to the power saving mode. In addition, the power saving mode settings menu may include a menu for controlling the operating state of the display device (100) to normal mode or power saving mode.

The controller (170) can receive a user input for controlling the power saving mode (S20). Accordingly, the controller (170) can control the operation mode of the display device (100) to the power saving mode (S30).

To summarize Fig. 11, the controller (170) can control the operation mode of the display device (100) to the power saving mode based on a user input that controls the power saving mode.

However, if the user has to enter the power saving mode setting menu every time to control the operation mode of the display device (100) to power saving mode, it may cause inconvenience to the user.

Additionally, if the user does not consider switching to power saving mode, power consumption of the display device (100) may continue to be wasted.

Accordingly, a display device (100) according to one embodiment of the present disclosure seeks to provide a power saving mode notification.

In relation to this, a method for providing a power saving mode notification by a display device (100) is described with reference to FIG. 12.

FIG. 12 is a flowchart illustrating a method for a display device to provide a power saving mode notification according to one embodiment of the present disclosure.

Figure 12 may be a step between steps S10 and S20 of Figure 11.

When the controller (170) enters the power saving mode setting menu, it can receive user input to activate the power saving mode notification (S40).

A power saving mode notification may be a notification to inform the user that the device may be entering power saving mode.

The controller (170) can set a power saving mode notification condition (S50).

The power saving mode condition may be a condition that must be satisfied for the controller (170) to output a power saving mode notification.

The controller (170) can set power saving mode conditions using the period and power consumption.

For example, the controller (170) may set the power saving mode condition to be when the current power consumption exceeds the first reference power consumption.

Alternatively, the controller (170) may set the power saving mode condition to be when the accumulated power consumption for a preset reference period exceeds a second reference power consumption.

Alternatively, the controller (170) may set the power saving mode condition as the average power consumption over a preset reference period exceeding a third reference power consumption.

The reference period may vary, such as one month, three months, or one year. The reference period may be a period set by user input. Alternatively, the reference period may be a period set by default in the display device (100).

The reference power consumption may be a power amount set by the user. Alternatively, the reference power consumption may be a power amount set by default for the display device (100). Alternatively, the reference power consumption may be determined by considering the average power consumption per household. Alternatively, the reference power consumption may be determined by considering the power consumption by time period. Alternatively, the reference power consumption may be determined by considering the power amount that serves as a standard for energy saving.

The controller (170) can obtain the power consumption (S60).

The controller (170) can obtain usage information of the display device (100) to determine whether the power saving mode condition is satisfied. The usage information of the display device (100) can include the power consumption of the display device (100).

The controller (170) can periodically obtain the power consumption. Alternatively, the controller (170) can obtain the power consumption in real time.

The power consumption acquired by the controller (170) may be the current power consumption. Alternatively, the power consumption acquired by the controller (170) may be the cumulative power consumption over a preset reference period. Alternatively, the power consumption acquired by the controller (170) may be the average power consumption over a preset reference period. Alternatively, the power consumption acquired by the controller (170) may be the power consumption by time zone.

The controller (170) can determine whether the power saving mode condition is satisfied based on the acquired power consumption amount (S70).

An example of a case where the power saving mode condition is satisfied is described with reference to FIG. 13.

Figure 13 is a graph showing the cumulative power consumption of a display device.

The controller (170) can set the power saving mode condition to be that the accumulated power consumption of the display device (100) exceeds the reference power consumption (p) during a preset reference period (t).

The controller (170) can obtain the accumulated power consumption of the display device (100).

The controller (170) can obtain that the power saving mode condition is satisfied at the time point (t1) when the accumulated power consumption reaches the reference power consumption (p).

Again, Figure 12 is explained.

If the controller (170) determines that the power saving mode condition is not satisfied, it can continue to obtain the power consumption amount.

When the controller (170) determines that the power saving mode condition is satisfied, it can output a power saving mode notification (S80).

The sleep mode notification may contain a message to obtain whether the control should be put into sleep mode.

Users can check the power saving mode notification and input whether to control it in power saving mode.

When the controller (170) receives a user input to control the power saving mode, it can control the operation mode of the display device (100) to the power saving mode.

According to an embodiment, at least one of the steps described in FIG. 12 may be omitted. Furthermore, according to an embodiment, the order in which each step described in FIG. 12 is performed may differ from the order described in FIG. 12.

To summarize FIG. 12, a display device (100) according to an embodiment of the present disclosure can be controlled to a power saving mode based on a user input that notifies a user when a power saving mode condition is satisfied and controls the power saving mode.

Accordingly, the display device (100) according to one embodiment of the present disclosure can notify the user that power consumption can be saved. In addition, inconvenience caused by the user being controlled to a power saving mode regardless of intention can be prevented.

Meanwhile, as described in FIGS. 6 to 10, there may be various ways to display the home menu in power saving mode.

Accordingly, the display device (100) according to an embodiment of the present disclosure recommends changing the setting state of the power saving mode based on usage information.

FIG. 14 is a flowchart illustrating a method for changing a setting state of a power saving mode of a display device according to an embodiment of the present disclosure.

Fig. 14 may be a previous step of step S10 of Fig. 11.

The controller (170) can obtain usage information (S100).

The controller (170) can obtain usage information of the display device (100).

As described above, the usage information may include at least one of item-specific usage history and item-specific login information.

Additionally, the usage information may include various information related to the use of the display device (100), such as the content viewed, the genre of the content viewed, the viewing time, and the amount of power consumed according to the use of the display device (100).

The controller (170) can recommend a change in setting status based on the acquired usage information (S110).

The controller (170) can analyze usage information and recommend changes to the power saving mode settings based on the analysis results.

The controller (170) can acquire and analyze usage information for a preset period of time. The preset period of time may be the minimum period required to determine the user's usage pattern.

The controller (170) may recommend a change in the setting status at a point in time when analysis of usage information for a preset period of time is completed.

The controller (170) may display a message recommending a change in the power saving mode settings.

In relation to this, it is explained with reference to Fig. 15.

FIG. 15 is an example of a pop-up window displayed by a display device according to an embodiment of the present disclosure to recommend changing the setting status of a power saving mode.

The controller (170) may display a pop-up window (510) to recommend changing the setting status of the power saving mode.

The pop-up window (510) may contain a message such as, "Your usage patterns have been analyzed. Would you like to change the settings to reduce TV power consumption?" However, this is merely an example and may contain various texts that suggest power-saving mode to the user.

The pop-up window (510) may include a 'yes' icon (511), a 'no' icon (512), and a 'view details' icon (513).

The controller (170) can change the setting state of the power saving mode when it receives an input selecting the 'Yes' icon (511).

The controller (170) can maintain the power saving mode setting state when receiving an input selecting the 'No' icon (512).

When the controller (170) receives an input selecting the 'View Details' icon (513), it can display at least one of the usage information and the information regarding the setting status to be changed.

For example, the controller (170) may provide a list of items frequently used by the user. Additionally, the controller (170) may recommend displaying icons corresponding to frequently used items in color.

Alternatively, the controller (170) may provide a list of genres that the user primarily watches. Furthermore, the controller (170) may recommend displaying icons corresponding to items that provide the genres that the user primarily watches in color.

Alternatively, the controller (170) may provide a list of items acquired as the user's favorite items. Additionally, the controller (170) may recommend including the favorite items in the sidebar (184).

Meanwhile, when the controller (170) receives an input for selecting the 'Detailed View' icon (513), it can display information on the predicted power consumption according to the change in the setting status.

Information regarding predicted power consumption may include power consumption after the configuration state is changed. Additionally, information regarding predicted power consumption may include power consumption that will be saved compared to before the configuration state is changed.

A user can determine whether to change the setting status by checking the predicted power consumption. The display device (100) according to an embodiment of the present disclosure can induce the user to change the setting status by providing the predicted power consumption.

Again, Figure 14 is explained.

The controller (170) can receive user input to change the setting state of the power saving mode (S120).

The controller (170) can receive an input for selecting the 'Yes' icon (511). Next, the controller (170) can change the setting status of the power saving mode (S130).

Accordingly, the power saving mode setting status can be changed to suit the user's intention.

To summarize Fig. 14, a display device (100) according to an embodiment of the present disclosure can recommend a change in the setting state of a power saving mode based on usage information.

That is, the display device (100) according to the embodiment of the present disclosure can recommend an optimal power saving mode considering the user's usage pattern.

According to an embodiment, the display device (100) may recommend a power saving operation based on usage information.

Power-saving operations may include various actions to conserve power consumption of the display device (100). For example, the power-saving operation may be an action to terminate background functions that are not currently in use. The controller (170) may obtain information related to background functions that are not currently in use based on usage information.

In relation to this, it is explained with reference to Fig. 16.

FIG. 16 is a diagram illustrating an example of a message displayed by a display device according to an embodiment of the present disclosure to recommend a power-saving operation.

The controller (170) may display a pop-up window (520) to recommend a power saving operation.
