[0100] 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).

[0101] The user can recognize whether the output interface (250) is manipulating the user input interface (230) or controlling the display device (100).

[0102] 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.

[0103] 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.

[0104] The power supply circuit (260) can resume power supply when a predetermined key provided in the remote control device (200) is operated.

[0105] The memory (270) can store various types of programs, application data, etc. required for the control or operation of the remote control device (200).

[0106] 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.

[0107] The controller (280) of the remote control device (200) can store and reference information regarding the frequency band that can wirelessly transmit and receive signals with the display device (100) paired with the remote control device (200) in the memory (270).

[0109] Additionally, the microphone (290) of the remote control device (200) can acquire voice.

[0110] A plurality of microphones (290) may be provided.

[0111] Next, Figure 4 is described.

[0112] Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.

[0113] Figure 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on a display (180).

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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).

[0121] 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).

[0122] 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.

[0123] Meanwhile, the display (180) included in the display device (100) may be a transparent display.

[0124] FIG. 5 is a drawing illustrating a transparent display and a light-blocking mechanism of a display device according to an embodiment of the present disclosure.

[0125] The display device (100) may include a transparent display (180) and a light-blocking mechanism (181).

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

[0127] Projection display type may be a type that uses technology to display images by projecting light onto a transparent screen.

[0128] 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.

[0129] The shading mechanism unit (181) may include a shield or an electric shading plate. In addition, the shading mechanism unit (181) may include a motor driver IC or an electric shading control IC.

[0130] The light-blocking mechanism (181) may be placed on the back of the transparent display (180). The light-blocking mechanism (181) may turn on the light-blocking mechanism to block the transparent display (180). Accordingly, the display device (100) may operate in a light-blocking mode. When the display device (100) operates in a light-blocking mode, the clarity and contrast of the image displayed by the transparent display (180) may be increased.

[0131] In addition, the shading mechanism (181) can turn off the shading mechanism so that the transparent display (180) is not shading. Accordingly, the display device (100) can operate in a transparent mode. When the display device (100) operates in a transparent mode, the aesthetics can be enhanced as the transparent display (180) appears transparent.

[0132] A display device (100) according to an embodiment of the present disclosure is intended to automatically apply a transparent mode or a light-blocking mode based on content or an operational state.

[0133] FIG. 6 is a block diagram of a display device according to an embodiment of the present disclosure.

[0134] The display device (100) may include at least some of an input unit (171), a video analysis unit (172), a judgment block (173), and a light blocking mechanism unit (174).

[0135] The input unit (171) can receive content through various methods such as HDMI (High-Definition Multimedia Interface), RF (Radio Frequency), or OTT (Over The Top).

[0136] The video analysis unit (172) can analyze the video of the content input through the input unit (171). For example, the video analysis unit (172) can obtain the saturation or saturation change rate for each region of the video of the content. The specific method by which the video analysis unit (172) analyzes the video of the content will be described below.

[0137] The judgment block (173) can determine whether the operating state of the display device (100) satisfies the transmission condition. A specific description of the transmission condition will be described below.

[0138] The shading mechanism unit (174) may have the same configuration as the shading mechanism (181) of Fig. 5. The shading mechanism unit (174) may shading the transparent display (180) based on at least one of the content analysis result of the video analysis unit (172) and the judgment result of the judgment block (173).

[0139] Meanwhile, the operations of the input unit (171), video analysis unit (172), judgment block (173), and shading mechanism unit (174) can be performed by the controller (170).

[0140] Figure 7 is a drawing showing an example of how a display device operates in a light-blocking mode or a transparent mode.

[0141] FIG. 7(a) is a drawing showing a display device (100) operating in a light-blocking mode, and FIG. 7(b) is a drawing showing a display device (100) operating in a transparent mode.

[0142] The controller (170) may operate in a transparent mode when the area of ​​an area in the image of the content where the saturation is lower than a preset level is more than half of the total area. In addition, the controller (170) may operate in a light-blocking mode when the area of ​​an area in the image of the content where the saturation is lower than a preset level is less than half of the total area.

[0143] Areas of the content's image where saturation is below a preset level are often referred to as background areas. For example, the background area may be an area displayed in a solid black color, as illustrated in Figure 7(a).

[0144] Accordingly, the controller (170) can operate in a transparent mode to allow the back of the transparent display (180) to be visible through the background area when the area of ​​the content image where the saturation is below a preset level is more than half of the total area. Accordingly, the aesthetics utilizing the transparent display (180) can be maximized.

[0145] Meanwhile, the area of ​​the region that serves as a reference for the controller (170) to operate in the transmission mode is not limited to 1 / 2 of the total area and may vary depending on the embodiment.

[0146] Next, the operation of the display device (100) according to the embodiment of the present disclosure will be described in more detail with reference to FIG. 8.

[0147] FIG. 8 is a flowchart illustrating an operation method of a display device according to an embodiment of the present disclosure.

[0148] The controller (170) can receive content (S11).

[0149] As described above in FIG. 6, the controller (170) can receive content through various methods such as HDMI (High-Definition Multimedia Interface), RF (Radio Frequency), or OTT (Over The Top).

[0150] In order to analyze the content, the controller (170) can divide the image of the content into multiple blocks (S13).

[0151] For example, the controller (170) may divide the content or the local area of ​​the content into 2040 (60×34) blocks. The area of ​​each of the plurality of blocks may be the same.

[0152] The controller (170) can obtain whether the number of low-saturation blocks is greater than or equal to a preset first reference number (S15).

[0153] A low saturation block may be a block among a plurality of blocks whose saturation remains below a preset level for a preset first reference time.

[0154] For example, a low-saturation block may be a block among multiple blocks whose APL (Average Picture Level) remains below level 5 for 3 minutes. The greater the number of low-saturation blocks, the larger the area of ​​the content image that is displayed as low-saturation.

[0155] When the controller (170) obtains that the number of low-saturation blocks is less than a preset first reference number, it can obtain whether the operating state of the display device (100) satisfies the transmission condition (S17).

[0156] The transparency condition may be a condition for determining whether the controller (170) will operate in a transparency mode. The transparency condition may be a condition preset in the display device (100). Additionally, the transparency condition may be a condition set by the user.

[0157] The penetration conditions are described in detail later with reference to FIGS. 9 to 12.

[0158] When the controller (170) obtains that the number of low-saturation blocks is greater than or equal to a preset first reference number, it can obtain whether or not the number of static blocks is greater than or equal to a preset second reference number (S19).

[0159] A static block may be a block among low-saturation blocks whose saturation change rate remains below a preset change rate for a preset second reference time.

[0160] For example, a static block could be a block where the APL change rate is less than 0.4% over a 3-minute period.

[0161] When the controller (170) determines that the number of static blocks is less than a preset second reference number, it can determine whether the operating state of the display device (100) satisfies the transmission condition (S17).

[0162] If the controller (170) obtains that the number of static blocks is greater than or equal to a preset second reference number, it can operate in a transparent mode (S21).

[0163] Static blocks may often be areas that display information or are not areas where primary objects are displayed.

[0164] Accordingly, if the controller (170) obtains that the number of static blocks is greater than or equal to the preset second reference number, there is no need to excessively increase the clarity, and thus it can operate in a transparent mode to emphasize aesthetics.

[0165] The controller (170) can operate in a light-blocking mode if the operating state of the display device (100) does not satisfy the transmission condition (S20), and can operate in a transmission mode if the transmission condition is satisfied (S21).

[0166] Meanwhile, as described above, the controller (170) can obtain whether the operating state of the display device (100) satisfies the transmission condition, and if the transmission condition is satisfied, can operate in the transmission mode.

[0167] The operating state of the display device (100) may include at least one of an operating mode of the display device (100), content output by the display device (100), an application executed by the display device (100), and an operating state related to a method by which the transparent display (180) displays content.

[0168] The transparency condition may include a condition in which the operating mode of the display device (100) is AOD (Always On Display) mode. Furthermore, the transparency condition may include at least one of a condition in which content is output based on a person's orientation and a condition in which a person's orientation is executed. Furthermore, the transparency condition may include a condition in which content is displayed on the transparent display (180) in a floating view or multi-view.

[0169] Next, the penetration conditions will be specifically described with reference to FIGS. 9 to 12.

[0170] FIG. 9 is an exemplary drawing of an AOD screen displayed by a display device according to an embodiment of the present disclosure.

[0171] The display device (100) can operate in AOD mode. The AOD mode may be a mode in which the display device (100) does not output content. The display device (100) can display an AOD screen while operating in AOD mode.

[0172] As shown in FIG. 9, the AOD screens (320) can provide information along with a background image, such as the first AOD screen (321), the second AOD screen (322), and the third AOD screen (323).

[0173] The information provided by the AOD screens (320) may include information such as current temperature and current time, but this is only an example.

[0174] Since the display device (100) does not output content in AOD mode, there may be no need to maintain clarity above a certain level.

[0175] Accordingly, the controller (170) can operate in a transparent mode when the display device (100) operates in AOD mode, thereby maximizing the aesthetic effect of the AOD screen (320).

[0176] That is, the transmission condition for the display device (100) according to the embodiment of the present disclosure to operate in a transmission mode may include a condition in which the display device (100) is in AOD mode.

[0177] FIG. 10 is an example drawing of a screen that outputs content displayed by a display device according to an embodiment of the present disclosure or displays it while an application is running.

[0178] Specifically, FIG. 10 is a drawing illustrating an example of a screen (330) displayed when a display device (100) outputs person-centered content or executes an application.

[0179] The first screen (331) may be a screen on which the call recipient is displayed while the video call application is running.

[0180] The second screen (332) may be a screen on which home training content is displayed.

[0181] The third screen (333) may be a screen on which AR (Augmented Reality) content is displayed.

[0182] The fourth screen (334) may be a screen on which individual music content is displayed.

[0183] As shown on the first screen, the person-centered application may be a video call application. Furthermore, as shown on the second to fourth screens (332, 333, 334), the person-centered content may include home training content, AR content, or individual music content.

[0184] In the case of person-centered applications and person-centered content, the importance of the area corresponding to the background among the areas of the screen displayed on the transparent display (180) may be somewhat lower than the importance of the area corresponding to the person, so it may not be necessary to maintain the clarity of the entire screen above a certain level.

[0185] Accordingly, the controller (170) can operate in transparent mode while the display device (100) outputs person-centered content or runs a person-centered application. This provides a sense of presence, similar to being face-to-face with a caller in the same space, exercising in the same space as an instructor, or experiencing a singer performing in front of the user.

[0186] That is, the transparency condition for the display device (100) according to the embodiment of the present disclosure to operate in a transparency mode may include at least one of a condition in which the display device (100) outputs content centered on a person and a condition in which a person-centered application is executed.

[0187] FIG. 11 is an exemplary drawing of a case where a display device according to an embodiment of the present disclosure outputs content on a full screen, and FIG. 12 is an exemplary drawing of a case where a display device according to an embodiment of the present disclosure outputs content on a partial screen.

[0188] Referring to FIG. 11, the transparent display (180) can display the image of the content in full screen mode (310). That is, the transparent display (180) can display the image of the content in the entire area of ​​the transparent display.

[0189] In this case, the controller (170) performs video analysis as described in FIG. 8 and can operate in a transparent mode or a light-blocking mode based on the analysis results.

[0190] Alternatively, the controller (170) may operate in the shading mode when the image of the content is displayed in full screen mode (310), if the controller (170) is preset to operate in the shading mode when the image of the content is displayed in full screen mode (310).

[0191] Referring to FIG. 12, the transparent display (180) can display the image of the content in some screen mode (340). For example, the transparent display (180) can display the image of the content in a floating view (341) or in a multi-view (342).

[0192] When displaying content images as a floating view (341), the transparent display (180) can display the content images in a portion (a1) of the transparent display (180) and display a background image in the entire portion (a2). In this case, the content images may appear to float on the background image. Accordingly, a user can view the content images along with the background image.

[0193] When the transparent display (180) displays the image of the content as a floating view (342), the image of the first content can be displayed in a first area (a3) ​​of the transparent display (180) and the image of the second content can be displayed in a second area (a4). Accordingly, the user can be provided with multiple contents simultaneously. Meanwhile, the transparent display (180) can display no image or a single color in the remaining area (a5) where the content is not displayed, depending on the horizontal and vertical ratios of the first and second content images.

[0194] When the transparent display (180) displays the image of the content as a floating view (341), the background image is displayed in the entire area, and when the image of the content is displayed as a multi-view, there may be an area where the content is not displayed.

[0195] Accordingly, the controller (170) can operate in a transparent mode when the transparent display (180) displays content as a floating view (341) or multi-view (342).

[0196] That is, the transparency condition for the display device (100) according to the embodiment of the present disclosure to operate in a transparency mode may include a condition in which the transparent display (180) displays content in a floating view (341) or multi-view (342).

[0197] Meanwhile, when the transparent display (180) operates in a transparent mode by displaying content as a floating view (341) or multi-view (342), the area through which light is transmitted may be the entire area of ​​the transparent display (180).

[0198] In some embodiments, when the transparent display (180) operates in a transparent mode by displaying content as a floating view (341) or multi-view (342), the area through which light is transmitted may be an area where content is not displayed.

[0199] That is, when the display device (100) according to the embodiment of the present disclosure operates in a transparent mode, the area through which light is transmitted may be at least a part of the area of ​​the transparent display (180).

[0200] Next, referring to FIG. 13, a method for obtaining an area for transmitting light among areas of a transparent display by a display device according to an embodiment of the present disclosure will be described.

[0201] FIG. 13 is a drawing for explaining a method for a display device according to an embodiment of the present disclosure to obtain an area for transmitting light among areas of a transparent display.

[0202] Fig. 13(a) may be an image of home training content. The image of home training content may include a person area (b1) and a background area (b2).

[0203] Fig. 13(b) may be an image in which the person area (b1) and the background area (b2) are separated from the image shown in Fig. 13(a).

[0204] According to an embodiment, the display device (100) can recognize not only people but also various objects, distinguish an area corresponding to the object and a background area, and transmit light only to the background area.

[0205] According to one embodiment of the present invention, the above-described method can be implemented as processor-readable code on a medium in which a program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage devices.

[0206] The display device described above is not limited to the configuration and method of the embodiments described above, and the embodiments may be configured by selectively combining all or part of each embodiment so that various modifications can be made.
