[0096] When the user input interface (230) has a touch screen, the user can input commands related to the display device (100) using the remote control device (200) by touching the soft keys of the touch screen. In addition, the user input interface (230) may have various types of input means that can be operated by the user, such as a scroll key or a jog key, and this embodiment does not limit the scope of the present invention.

[0097] The sensor (240) may include a gyro sensor (241) or an acceleration sensor (243), and the gyro sensor (241) may sense information about the movement of the remote control device (200).

[0098] For example, the gyro sensor (241) can sense information about the operation of the remote control device (200) based on the x, y, and z axes, and the acceleration sensor (243) can sense information about the movement speed of the remote control device (200). Meanwhile, the remote control device (200) can further include a distance measuring sensor, so as to sense the distance to the display (180) of the display device (100).

[0099] The output interface (250) can output a video or audio signal corresponding to an operation of the user input interface (230) or a signal transmitted from the display device (100).

[0100] The user can recognize whether the output interface (250) is manipulating the user input interface (230) or controlling the display device (100).

[0101] For example, the output interface (250) may include an LED (251) that lights up when the user input interface (230) is operated or a signal is transmitted and received with the display device (100) via the wireless communication unit (225), a vibrator (253) that generates vibrations, a speaker (255) that outputs sound, or a display (257) that outputs images.

[0102] In addition, the power supply circuit (260) supplies power to the remote control device (200), and power waste can be reduced by stopping the power supply when the remote control device (200) does not move for a predetermined period of time.

[0103] The power supply circuit (260) can resume power supply when a predetermined key provided in the remote control device (200) is operated.

[0104] The memory (270) can store various types of programs, application data, etc. required for the control or operation of the remote control device (200).

[0105] When the remote control device (200) wirelessly transmits and receives signals through the display device (100) and the RF circuit (221), the remote control device (200) and the display device (100) transmit and receive signals through a predetermined frequency band.

[0108] Additionally, the microphone (290) of the remote control device (200) can acquire voice.

[0109] A plurality of microphones (290) may be provided.

[0110] Next, Figure 4 is described.

[0111] Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

[0112] Figure 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on a display (180).

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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).

[0120] 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).

[0121] 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.

[0122] Meanwhile, the display (180) included in the display device (100) may be a transparent display.

[0123] FIG. 5 is a drawing showing a display device according to an embodiment of the present disclosure viewed from various directions.

[0124] Specifically, FIG. 5(a) is a drawing showing a view of the display device (100) as viewed from above, FIG. 5(b) is a drawing showing a view of the display device (100) as viewed from the front, FIG. 5(c) is a drawing showing a view of the display device (100) as viewed from the side, and FIG. 5(d) is a drawing showing a view of the display device (100) as viewed from the back.

[0125] The display device (100) may include some or all of a transparent display (180), a sensor (300), a circuit driver (400), and lighting (500).

[0126] The transparent display (180) may be either a projection display type or a transmissive display type.

[0144] The light emitting unit (174) may include a light (500). At this time, the light (500) may be a bar-shaped LED lamp.

[0145] The display device (100) according to an embodiment of the present disclosure can control the light emission mode of the lighting differently based on at least one of the detection result of the sensor (300) detecting the user and the state of the display device (100).

[0146] First, with reference to FIGS. 7 to 9, a method for controlling the light emission mode of the light (500) when the display device (100) according to an embodiment of the present disclosure operates in AOD mode will be described.

[0147] FIG. 7 is a drawing illustrating a display device according to an embodiment of the present disclosure operating in AOD mode.

[0148] The operating mode of the display device (100) may be an AOD (Always On Display) mode that does not output content. The display device (100) may display an AOD screen while operating in the AOD mode.

[0149] Referring to FIG. 7, the transparent display (180) can be divided into a first area (a1) and a second area (a2) in AOD mode.

[0150] The transparent area (a1) may be an area that remains transparent in the AOD mode. That is, the first area (a1) may be an area where no image is displayed in the AOD mode.

[0151] The AOD area (a2) may be an area where an AOD image is displayed in AOD mode. The AOD image may include information such as the current time, weather, and current temperature. Additionally, the AOD image may include a background image.

[0152] Meanwhile, various AOD images may be displayed in the AOD area (a2) depending on the embodiment.

[0153] FIGS. 8 and 9 are drawings for explaining the light emission mode of the AOD image and lighting displayed in the AOD area while the display device according to an embodiment of the present disclosure operates in the AOD mode.

[0155] The controller (170) can display a welcome message (Message) in the AOD area (a2) when the sensor (300) detects a user.

[0156] For example, while the position detection sensor does not detect a user, the controller (170) may determine that the user is absent. While the user is absent, the controller (170) may turn off the light (500).

[0157] The controller (170) can detect the user through a position detection sensor when the user returns to the vicinity of the display device (100) after determining that the user is absent. When the controller (170) detects the user, the controller (170) can turn on the light and display a welcome message in the AOD area (a2). In addition, the controller (170) can control the light emission mode of the light (500) to a first light emission mode. The first light emission mode can be a mode for providing an effect such as light seeping from the bottom to the top of the transparent display (180) according to the light emission of the light (500).

[0158] The controller (170) may display a welcome message in the second area (a2) and then display another AOD image. For example, the controller (170) may display card news including information such as weather, major news, and stocks in the AOD area (a2) as illustrated in FIG. 9.

The second light emission mode may be a mode for providing an effect such as a light gently flickering according to the light emission of the light (500).

[0159] Next, with reference to FIGS. 10 to 15, a method for controlling the light emission mode of a light (500) based on the detection results of a user's voice and location detected by a display device according to an embodiment of the present disclosure will be described.

[0160] FIG. 10 is a flowchart for explaining an operation method of a display device according to an embodiment of the present disclosure.

[0161] When the controller (170) detects the user's voice utterance (S101), it can analyze the user's voice and location (S103).

[0162] For example, when the controller (170) detects a user's spoken word through the voice recognition unit (171), it can detect the user's voice and location and initiate analysis of the voice and location.

[0163] The controller (170) can determine the light emission mode of the light (500) based on the analysis results (S105).

[0164] Specifically, the main SoC can determine the light emission mode of the light (500).

[0165] The controller (170) can process data related to the light emission mode (S107).

[0166] Specifically, the main SoC can transmit data related to the lighting mode to the LED microcomputer via I2C (Inter-Integrated Circuit) communication.

[0167] The controller (170) can control the light emission mode of the light (500) (S109).

[0168] The light (500) can emit light according to a light emission mode controlled by the controller (170).

[0169] Next, a method for analyzing each of a user's voice and location by a display device (100) according to an embodiment of the present disclosure will be described.

[0170] FIG. 11 may be a flowchart for explaining a method for a display device according to an embodiment of the present disclosure to analyze a user's voice.

[0171] Fig. 11 may be a flowchart specifying step S103 of Fig. 10.

[0172] The controller (170) can initiate voice acquisition (S111).

[0173] The controller (170) can initiate voice acquisition when the voice detection sensor detects a trigger word spoken by the user. The controller (170) can initiate voice acquisition and acquire the command spoken by the user.

[0174] The controller (170) can analyze the acquired voice (S11).

[0175] The controller (170) can analyze the user's command included in the acquired voice.

[0176] FIG. 12 may be a flowchart for explaining a method for a display device according to an embodiment of the present disclosure to analyze a user's location.

[0177] Fig. 11 may be a flowchart specifying step S103 of Fig. 10.

[0178] The controller (170) can initiate operation of the position detection sensor (S121).

[0179] The controller (170) can initiate operation of the position detection sensor when the voice detection sensor detects a trigger word spoken by the user. The position detection sensor can detect the user's location.

[0180] The controller (170) can analyze the user's location detected through the sensor (S123).

[0181] For example, the controller (170) can analyze the user's position relative to the display device (100).

[0182] The controller (170) can perform a position detection sensor command (S125).

[0183] The controller (170) can determine the light-emitting mode by considering the user's location according to a position detection sensor command.

[0184] The steps of FIGS. 11 and 12 may be performed simultaneously or sequentially, depending on the embodiment.

[0185] Next, the operation of the display device (100) according to an embodiment of the present disclosure will be described with reference to FIGS. 13 to 15.

[0186] FIG. 13 is a drawing for explaining the light-emitting mode of a display device according to an embodiment of the present disclosure when the trigger word is detected.

[0187] Fig. 13(a) is a drawing showing a user speaking a trigger word from the side of the display device (100), and Fig. 14(a) is a drawing showing a user speaking a trigger word from the front of the display device (100).

[0188] The trigger word may be a word or phrase that initiates the sensor (500) to acquire a voice command. The trigger word may be "Hi, LG," but this is merely an example.

[0189] When the sensor (300) detects the user's utterance, the controller (170) can detect the user's location and control the light-emitting mode to the third light-emitting mode based on the user's location.

[0190] The third light emission mode may be a light emission mode that controls the brightness of the area closest to the user among the areas where the light (500) emits light to be brightest.

[0191] Accordingly, the user can intuitively recognize that the display device (100) has detected his / her trigger word.

[0192] FIG. 14 is a drawing for explaining the light emission mode while the display device according to an embodiment of the present disclosure analyzes a command.

[0193] When the controller (170) detects a trigger word, it obtains a command spoken by the user, analyzes the command, and controls the light-emitting mode to the fourth light-emitting mode while analyzing the command.

[0194] The fourth light emission mode may be a light emission mode that has an effect in which the brightest light emission area among the light emission areas (500) appears to flow from left to right.

[0195] Accordingly, the user can intuitively recognize that the display device (100) is analyzing his / her command.

[0196] FIG. 15 is a drawing for explaining a light-emitting mode while a display device according to an embodiment of the present disclosure responds to a command.

[0197] The controller (170) can respond to a command after analysis of the command is completed.

[0198] For example, if the command is 'Turn on the TV', the controller (170) can turn on the power of the display device (100) in response to the command. The controller (170) can control the light emission mode of the light (500) to the fifth light emission mode while the display device (100) is turned on.

[0199] The fifth light-emitting mode may be a mode for providing an effect such as a light gently flickering according to the light emission of the light (500). It may be a mode for providing an effect such as a light gently flickering according to the light emission of the light (500).

[0200] Accordingly, the user can intuitively recognize that the display device (100) is responding to the command he or she has spoken.

[0201] Meanwhile, the specific descriptions related to each of the aforementioned light-emitting modes are merely examples, and each light-emitting mode may be set in various ways depending on the embodiment.
