Description

Display device and method of operation thereof

[0001] The present disclosure relates to a display device that provides a content list that allows for rapid access to content under low power mode.

[0002] Digital TV services using wired or wireless communication networks are becoming commonplace. Digital TV services can provide a variety of services that were not available through existing analog broadcasting services.

[0003] For example, digital TV services such as IPTV (Internet Protocol Television) and smart TV provide interactivity that allows users to actively select the types of programs and viewing time. Based on this interactivity, IPTV and smart TV services can also provide various additional services, such as internet search, home shopping, and online games.

[0004] Recent TVs offer an Always On Display (AOD) feature that continues to display some information even when the screen is off.

[0005] However, when providing conventional AOD functions, the screen is limited to displaying only simple information such as the time and photos due to issues with storage space and power consumption, which restricts the content provided.

[0006] In addition, when the AOD function is provided, there are only two options: turning off the TV completely or turning on the TV and entering the home screen. In this case, there is the inconvenience of having to turn on the power and go through the home screen to access the content in AOD mode.

[0007] The purpose of the present disclosure may be to provide a content list containing various types of content with low capacity under low power mode.

[0008] The purpose of the present disclosure may be to provide a service that enables viewers to quickly access desired content under low power mode.

[0011] A method of operation of a display device according to an embodiment of the present disclosure may include: generating a content list based on content information; receiving a request for entry into a low power mode; displaying the generated content list under the low power mode in accordance with the received request; exiting the low power mode in accordance with a command to select one of a plurality of content items included in the content list; and playing content corresponding to the selected content item.

[0012] According to an embodiment of the present disclosure, a user can immediately play desired content by selecting any one of the content items included in the content list under low power mode.

[0013] Accordingly, the inconvenience of having to turn on the power of the display device separately and navigate to the desired content in AOD mode can be significantly reduced.

[0014] According to an embodiment of the present disclosure, as folder and content types are provided on the screen in an AOD state, the user can systematically manage the content list and quickly access the desired content.

[0015] According to an embodiment of the present disclosure, an improved user experience can be provided in which a list of content with a small capacity is displayed on the screen in an AOD state, separated by source, thereby allowing the viewer to quickly access the content they want.

[0016] According to an embodiment of the present disclosure, an improved user experience can be provided in which a list of small-capacity content is displayed on the screen in an AOD state, separated by user account, thereby allowing the viewer to quickly access the content they want.

[0017] According to an embodiment of the present disclosure, a user can easily edit a list of contents provided under a low-power mode of a display device through an external device.

Additionally, the user input interface (230) may be equipped with various types of input means that the user can operate, such as scroll keys or jog keys, and this embodiment does not limit the scope of the present invention.

[0089] The sensor (240) may be equipped with a gyroscope sensor (241) or an accelerometer sensor (243), and the gyroscope sensor (241) may sense information regarding the movement of the remote control device (200).

[0090] For example, the gyroscope sensor (241) can sense information regarding the operation of the remote control device (200) based on the x, y, and z axes, and the accelerometer sensor (243) can sense information regarding the movement speed of the remote control device (200). Meanwhile, the remote control device (200) may further be equipped with a distance measuring sensor to sense the distance to the display (180) of the display device (100).

[0091] The output interface (250) can output a video or audio signal corresponding to the operation of the user input interface (230) or a signal transmitted from the display device (100).

[0092] The user can recognize whether the output interface (250) is operated by the user input interface (230) or whether the display device (100) is controlled.

[0093] For example, the output interface (250) may be equipped with an LED (251) that lights up when the user input interface (230) is operated or when a signal is transmitted or received with the display device (100) through the wireless communication circuit (220), a vibrator (253) that generates vibration, a speaker (255) that outputs sound, or a display (257) that outputs video.

[0094] Additionally, the power supply circuit (260) supplies power to the remote control device (200), and can reduce power waste by stopping the power supply when the remote control device (200) does not move for a predetermined period of time.

[0095] The power supply circuit (260) can resume power supply when a predetermined key provided in the remote control device (200) is operated.

[0096] The memory (270) can store various types of programs, application data, etc. required for the control or operation of the remote control device (200).

[0097] When the remote control device (200) transmits and receives signals wirelessly through the RF circuit (221) and the display device (100), the remote control device (200) and the display device (100) transmit and receive signals through a predetermined frequency band.

[0098] The controller (280) of the remote control device (200) can store and refer to information regarding frequency bands, etc., that can wirelessly transmit and receive signals with the display device (100) paired with the remote control device (200) in the memory (270).

The controller (280) can transmit a signal corresponding to a predetermined key operation of the user input interface (230) or a signal corresponding to the movement of the remote control device (200) sensed by the sensor (240) to the display device (100) through the wireless communication circuit (220).

[0100] In addition, the microphone (290) of the remote control device (200) can acquire voice.

[0101] The microphone (290) may be provided in multiple numbers.

[0102] Next, Figure 4 is explained.

[0103] Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

[0104] FIG. 4(a) illustrates a pointer (205) corresponding to a remote control device (200) being displayed on a display (180).

[0105] 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). Since the pointer (205) of the remote control device (200) moves and is displayed according to the movement in 3D space as shown in the drawing, it can be named a spatial remote control.

[0106] FIG. 4(b) illustrates that when the 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 in response.

[0107] Information regarding 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 regarding the movement of the remote control device (200). The display device (100) can display the pointer (205) to correspond to the calculated coordinates.

[0108] FIG. 4(c) illustrates a case where, while pressing a specific button within the remote control device (200), the user moves the remote control device (200) away from the display (180). By doing so, the selected area within the display (180) corresponding to the pointer (205) can be zoomed in and enlarged.

[0109] Conversely, when the user moves the remote control device (200) closer to the display (180), the selected area within the display (180) corresponding to the pointer (205) can be zoomed out and reduced in size.

[0110] Meanwhile, when the remote control device (200) moves away from the display (180), the selected area may be zoomed out, and when the remote control device (200) moves closer to the display (180), the selected area may be zoomed in.

[0111] Additionally, when a specific button within the remote control device (200) is pressed, recognition of up-down and left-right movement may be excluded. That is, when the remote control device (200) moves away from or closer to the display (180), up-down, left-right movement is not recognized, and only forward-backward movement is recognized. When the specific button within the remote control device (200) is not pressed, only the pointer (205) moves according to the up-down, left-right movement of the remote control device (200).

[0112] Meanwhile, the movement speed or direction of movement of the pointer (205) can correspond to the movement speed or direction of movement of the remote control device (200).

[0113] 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, the pointer (205) can be an object of various shapes other than the arrow shape shown in the drawing. For example, it may be a concept including a point, a cursor, a prompt, a thick outline, etc. Furthermore, the pointer (205) can be displayed corresponding to either a point on the horizontal axis or a vertical axis on the display (180), and it is also possible to display it corresponding to multiple points, such as a line or a surface.

[0114] FIG. 5 is a block diagram illustrating the configuration of a mobile terminal according to one embodiment of the present invention.

[0116] Referring to FIG. 5, the mobile terminal (500) may include a communication circuit (510), an input interface (520), a memory (530), an output interface (540), and a processor (590).

[0117] The communication circuit (510) can transmit and receive data with external devices such as other mobile terminals or servers using wired and wireless communication technology.

[0118] The communication circuit (510) can perform communication using any one of the following communication standards: GSM (Global System for Mobile communication), CDMA (Code Division Multi Access), LTE (Long Term Evolution), 5G, WLAN (Wireless LAN), Wi-Fi (Wireless-Fidelity), Bluetooth (Bluetooth), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), ZigBee, and NFC (Near Field Communication).

[0119] The input interface (520) may include a camera (521) for inputting a video signal, a microphone (522) for receiving an audio signal, a user input interface for receiving information from a user, etc.

[0120] Here, the camera (521) or microphone (522) may be treated as a sensor, and the signal obtained from the camera (521) or microphone (522) may be referred to as sensing data or sensor information.

[0121] The memory (530) can store various software and data related to the operation of the mobile terminal (500).

[0128] Referring to FIG. 6, the controller (170) of the display device (100) can obtain content information (S601).

[0129] Content information may include at least one of the following: an access address of the content (e.g., URL), a thumbnail of the content, a name of the content, a search term, information about a channel that the user has watched for a certain amount of time or information about a broadcast program that the user has watched for a certain amount of time.

[0130] The content can be any one of video content, image content, or audio content.

[0131] The search term may be either text entered for searching on the display device (100) or text entered for searching on an external device. The external device may be the mobile terminal (500) of FIG. 5, and the display device (100) may receive keywords from the mobile terminal (500).

[0132] Information about the channel may include one or more of the channel number or the channel name.

[0133] Information about a broadcast program may include one or more of the name of the broadcast program or a thumbnail of the broadcast program.

[0134] In another embodiment, the content information may be information generated based on the user's viewing history. The controller (170) may generate content information from the viewing history through an artificial intelligence model stored in memory (140). The viewing history may be data indicating when and what content the user watched.

[0135] An artificial intelligence model may be an artificial neural network-based model trained by a deep learning algorithm or a machine learning algorithm.

[0136] An artificial intelligence model may be a model trained based on collaborative filtering or content-based filtering methods.

[0137] Collaborative filtering is a method that recommends content liked by other users by identifying the preferences of other users with tastes similar to a user's viewing history.

[0138] Content-based filtering is a method that analyzes the characteristics of individual content (e.g., genre, director, theme, actors, etc.) to recommend content with similar attributes.

[0139] An artificial intelligence model can convert a user's viewing history data into a vector and can be supervised learning to minimize a loss function representing the difference between the converted vector and the target vector corresponding to the labeled data.

[0140] In one embodiment, the content information may include one or more of the information received from the display device (100) or the mobile terminal (500).

[0141] The controller (170) can store the acquired content information in memory (140).

[0142] The controller (170) can generate a content list based on the acquired content information (S603).

[0143] A content list may include multiple content items. Each content item may include at least one of the name of the content, a thumbnail of the content, source information of the content, or an access address (URL) of the content.

[0144] Each content item can be a selectable item.

[0145] The controller (170) can generate a content list containing multiple content items using content information.

[0146] In particular, the controller (170) can create a content list containing content items using the access address of the content.

[0147] In one embodiment, the controller (170) can generate a content list using content information received from an external device. The external device may be a mobile terminal (500). The mobile terminal (500) may transmit keywords and a type of content to the display device (100) in addition to the content information. The keyword may be the name of a folder containing the content list. The type of content may indicate a type of content.

[0148] The type of content can be either a video type or an audio type. In another example, the type of content can represent the genre of the content. The genre of the content can be a movie, an influencer video, or a drama.

[0149] The controller (170) can automatically create a folder using keywords received from the mobile terminal (500) and can store a list of contents within the created folder.

[0150] In another embodiment, the controller (170) may generate a content list using content information regarding content viewed on the display device (100). For example, the controller (170) may include in the content list at least one of a broadcast program viewed on the display device (100) for a certain period of time or longer, a channel of the broadcast program, a program of a similar genre to the broadcast program, or a channel of a broadcast program of a similar genre. As another example, the controller (170) may include a video viewed on the display device (100) through a video streaming service application in the content list items.

[0151] In another embodiment, the controller (170) can generate a content list using first content information received from an external device and second content information regarding content viewed on the display device (100).

[0152] The controller (170) can store the generated content list in memory (140).

[0153] The controller (170) can determine whether it has received a request to enter low power mode (S605).

[0154] The power mode of the display device (100) may include a low power mode and a normal power mode. The normal power mode may be a mode in which power is consumed so that the display device (100) can use all functions. The low power mode may be a mode to minimize power consumption by operating only some functions of the display device (100). For example, the low power mode may be a mode in which the display device (100) performs an AOD function.

[0155] The low power mode may be referred to as AOD mode. The low power mode may be a mode in which not all applications installed on the display device (100) are running, or a mode in which only a very small number of applications are running. The low power mode may be a mode in which low-capacity information is continuously displayed while the power of the display device (100) is turned off.

[0156] When the controller (170) receives a power off command while the power of the display device (100) is on and the AOD function is activated, the controller (170) can enter the power mode of the display device (100) into a low power mode. That is, the controller (170) can recognize the power off command received while the AOD function is activated as a request to enter a low power mode.

[0157] The controller (170) can receive a power off command from the remote control device (200) or receive a power off command via the user's voice command.

[0158] When the controller (170) determines that it has received a request to enter low power mode, it can display the generated content list on the display (180).

[0159] The controller (170) can display a list of contents stored in memory (140) on the display (180) in response to receiving a request to enter low power mode.

[0160] In one embodiment, the controller (170) can automatically display a content list on the display (180) as the power mode changes from a normal power mode to a low power mode.

[0161] In another embodiment, the controller (170) can display a content list on the display (180) in response to a request to display a content list under low power mode.

[0162] FIG. 7a is a drawing illustrating a process for setting the display of a content list under low power mode, and FIGS. 7b to 7e are drawings illustrating a content list displayed under low power mode according to an embodiment of the present disclosure.
