[0033] Furthermore, the network interface 133 can receive firmware update information and update files provided by the network provider, and can transmit data to the internet, content providers, or network providers.

[0034] The network interface 133 can select and receive (or download) desired applications from among those made publicly available (open) via the network.

[0035] The memory 140 can store programs for each signal processing and control within the controller 170, and can also store processed video, audio, or data.

[0036] Furthermore, the memory 140 can also temporarily store video, audio, or data of signals input from the external device interface 135 or the network interface 133, and can also store image-related information through its channel memory function.

[0037] The memory 140 can store applications or application lists that are input from the external device interface 135 or the network interface 133.

[0038] The display device 100 can play and provide to the user content files (for example, video files, still image files, music files, document files, application files, etc.) stored in the memory 140.

[0039] The user input interface 150 can transmit signals input by the user to the controller 170, or transmit signals from the controller 170 to the user. For example, the user input interface 150 can receive and process control signals such as power on / off, channel selection, and screen settings from the remote control device 200, or process control signals from the controller 170 to transmit them to the remote control device 200, depending on various communication methods such as Bluetooth™, UWB (Ultra Wideband), ZigBee, RF (Radio Frequency) communication, or infrared (Infrared Ray) communication.

[0040] Furthermore, the user input interface 150 can transmit control signals input from local keys (not shown), such as the power key, channel key, volume key, and setting value, to the controller 170.

[0041] The video signal processed by the controller 170 is input to the display 180 and displayed as the corresponding image. The video signal processed by the controller 170 is also input to an external output device via the external device interface 135.

[0042] The audio signal processed by the controller 170 is output as audio via the speaker 185. The audio signal processed by the controller 170 is also input to an external output device via the external device interface 135.

[0043] Furthermore, the controller 170 can control the overall operation of the display device 100.

[0044] The controller 170 can control the display device 100 by user commands or internal programs input via the user input interface 150, and can connect to a network to allow the user to download desired applications or application lists to the display device 100.

[0045] The controller 170 ensures that the channel information selected by the user, along with the processed video or audio signal, is output via the display 180 or speaker 185.

[0046] Furthermore, the controller 170 ensures that video signals and / or audio signals from an external device, such as a camera or camcorder, input via the external device interface 135 in response to an external device video playback command received via the user input interface 150, are output via the display 180 and / or speaker 185.

[0047] On the other hand, the controller 170 can control the display 180 to display video, for example, by controlling it so that at least one of the following is displayed on the display 180: broadcast video input via the tuner 131, external input video input via the external device interface 135, video input via the network interface unit 133, or video stored in the memory 140. In this case, the video displayed on the display 180 may be a still image or a moving image, and may be a 2D image or a 3D image.

[0048] Furthermore, the controller 170 can control the playback of at least one of the contents stored in the display device 100, received broadcast content, or external input content received from an external source. The content can take various forms, such as broadcast video, external input video, audio files, still images, connected web pages, and document files.

[0049] The wireless communication interface 173 can communicate with external devices via wired or wireless communication. The wireless communication interface 173 can perform short-range communication with external devices. To this end, the wireless communication interface 173 can support short-range communication by utilizing at least one of the following technologies: Bluetooth, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB, ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, or Wireless USB (Wireless Universal Serial Bus) technology. The wireless communication interface 173 can support wireless communication between the display device 100 and the wireless communication system, between the display device 100 and other display devices, or between the display device 100 and the network where the display device (or external server) is located, via a wireless area network. The wireless area network may include wireless personal area networks.

[0050] Here, other display devices may include wearable devices (such as smartwatches, smart glasses, HMDs (head-mounted displays), etc.) and mobile terminals such as smartphones that can exchange (or interact with) data with the display device 100 according to this disclosure. The wireless communication interface 173 can sense (or recognize) wearable devices that can communicate in the vicinity of the display device 100.

[0051] Furthermore, if the sensed wearable device is a device authenticated to communicate with the display device 100 according to this disclosure, the controller 170 can transmit at least a portion of the data processed by the display device 100 to the wearable device via the wireless communication interface 173. Thus, the user of the wearable device can access the data processed by the display device 100 through the wearable device.

[0052] The display 180 can generate drive signals by converting video signals, data signals, OSD (On Screen Display) signals processed by the controller 170, or video signals, data signals, etc. received by the external device interface 135, into R, G, and B signals, respectively.

[0053] On the other hand, the display device 100 shown in Figure 1 is merely one embodiment of the present disclosure, so some of the illustrated components may be integrated, added, or omitted depending on the specifications of the display device 100 actually implemented.

[0054] In other words, two or more components may be integrated into a single component as needed, or one component may be subdivided into two or more components. Furthermore, the functions performed by each block are for illustrative purposes only, and their specific operation or apparatus does not limit the scope of the rights of this disclosure.

[0055] According to yet another embodiment of the present disclosure, the display device 100 may not include a tuner 131 and a demodulator 132, as shown in Figure 1, and may also receive and play video via a network interface 133 or an external device interface 135.

[0056] For example, the display device 100 may be implemented separately as a video processing device such as a set-top box for receiving broadcast signals or content from various network services, and a content playback device for playing back content input from the video processing device.

[0057] In this case, the operation method of the display device according to the embodiment of the present disclosure described below may be performed not only by the display device 100 as described with reference to Figure 1, but also by any one of the following: a separate video processing device such as a set-top box, or a content playback device equipped with a display 180 and an audio output unit 185.

[0058] Next, with reference to Figures 2 and 3, a remote control device according to one embodiment of the present disclosure will be described.

[0059] Figure 2 is a block diagram of a remote control device 200 according to one embodiment of the present disclosure, and Figure 3 shows an example of the actual configuration of the remote control device 200 according to one embodiment of the present disclosure.

[0060] First, referring to Figure 2, the remote control device 200 may include a fingerprint recognition device 210, a wireless communication circuit 220, a user input interface 230, a sensor 240, an output interface 250, a power supply circuit 260, a memory 270, a controller 280, and a microphone 290.

[0061] Referring to Figure 2, the wireless communication circuit 220 transmits and receives signals to any one of the display devices 100 according to the embodiments of this disclosure described above.

[0062] The remote control device 200 may be equipped with an RF circuit 221 that can send and receive signals with the display device 100 according to an RF communication standard, and an IR circuit 223 that can send and receive signals with the display device 100 according to an IR communication standard. The remote control device 200 may also be equipped with a Bluetooth circuit 225 that can send and receive signals with the display device 100 according to a Bluetooth communication standard. The remote control device 200 may also be equipped with an NFC (Near Field Communication) circuit 227 that can send and receive signals with the display device 100 according to an NFC communication standard, and a WLAN (Wireless LAN) circuit 229 that can send and receive signals with the display device 100 according to a WLAN (Wireless LAN) communication standard.

[0063] Furthermore, the remote control device 200 transmits a signal containing information about the movement of the remote control device 200 to the display device 100 via the wireless communication circuit 220.

[0064] On the other hand, the remote control device 200 can receive signals transmitted by the display device 100 via the RF circuit 221 and, if necessary, transmit commands to the display device 100 via the IR circuit 223 regarding power on / off, channel change, volume change, etc.

[0065] The user input interface 230 may consist of a keypad, buttons, a touchpad, or a touchscreen. The user can input commands related to the display device 100 to the remote control device 200 by operating the user input interface 230. If the user input interface 230 includes hard key buttons, the user can input commands related to the display device 100 to the remote control device 200 by pushing the hard key buttons. This will be explained with reference to Figure 3.

[0066] Referring to Figure 3, the remote control device 200 may include multiple buttons. These buttons may include a fingerprint recognition button 212, a power button 231, a groove button 232, a live button 233, an external input button 234, a volume control button 235, a voice recognition button 236, a channel change button 237, a confirmation button 238, and a back button 239.

[0067] The fingerprint recognition button 212 may be a button for recognizing the user's fingerprint. In one embodiment, the fingerprint recognition button 212 is capable of being pushed and can also receive both a push operation and a fingerprint recognition operation.

[0068] The power button 231 may also be a button for turning the power of the display device 100 on or off.

[0069] The grooved button 232 may also be a button for moving to the home screen of the display device 100.

[0070] The live button 233 may also be a button for displaying a real-time broadcast program.

[0071] The external input button 234 may also be a button for receiving an external input connected to the display device 100.

[0072] The volume control button 235 may also be a button for adjusting the volume level output by the display device 100.

[0073] The voice recognition button 236 may also be a button for receiving and recognizing the user's voice.

[0074] The channel change button 237 may also be a button for receiving the broadcast signal of a specific broadcast channel.

[0075] The confirmation button 238 may be a button for selecting a specific function, and the back button 239 may be a button for returning to the previous screen.

[0076] Let's explain Figure 2 again.

[0077] If the user input interface 230 includes a touchscreen, the user can input commands related to the display device 100 using the remote control device 200 by touching the soft keys on the touchscreen. Furthermore, the user input interface 230 can be equipped with various types of input means that the user can operate, such as scroll keys and jog keys, and this embodiment does not limit the scope of the rights of this disclosure.

[0078] The sensor 240 may include a gyro sensor 241 or an accelerometer 243, and the gyro sensor 241 can sense information regarding the movement of the remote control device 200.

[0079] For example, the gyro sensor 241 can sense information regarding the operation of the remote control device 200 with respect to the x, y, and z axes, and the accelerometer 243 can sense information regarding the movement speed of the remote control device 200. On the other hand, the remote control device 200 may also be equipped with a distance measuring sensor that can sense the distance to the display 180 of the display device 100.

[0080] The output interface 250 can output video or audio signals that correspond to the operation of the user input interface 230 or to signals transmitted from the display device 100.

[0081] The user can recognize whether the user input interface 230 is being operated or whether the display device 100 is being controlled via the output interface 250.

[0082] For example, the output interface 250 may include an LED 251 that lights up when the user input interface 230 is operated or when signals are sent 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.

[0083] Furthermore, the power supply circuit 260 supplies power to the remote control device 200, and if the remote control device 200 is not operating for a predetermined period of time, the power supply is interrupted, thereby reducing power waste.

[0084] The power supply circuit 260 can resume power supply when a predetermined key provided on the remote control device 200 is operated.

[0085] Memory 270 stores various types of programs, application data, etc., necessary for controlling or operating the remote control device 200.

[0086] When the remote control device 200 transmits and receives signals wirelessly with the display device 100 via the RF circuit 221, the remote control device 200 and the display device 100 transmit and receive signals through a predetermined frequency band.

[0087] The controller 280 of the remote control device can store and refer to information in its memory 270 regarding the frequency band and other information that allows it to wirelessly send and receive signals with the display device 100, which is paired with the remote control device 200.

[0088] The controller 280 controls various matters related to the control of the remote control device 200. The controller 280 can transmit signals corresponding to predetermined key operations on the user input interface 230 or signals corresponding to the movement of the remote control device 200 sensed by the sensor 240 to the display device 100 via the wireless communication unit 225.

[0089] Furthermore, the microphone 290 of the remote control device 200 can acquire sound.

[0090] Multiple microphones 290 may be provided.

[0091] Next, I will explain Figure 4.

[0092] Figure 4 shows an example of utilizing the remote control device 200 according to the embodiment of this disclosure.

[0093] Figure 4(a) illustrates that a pointer 205 corresponding to the remote control device 200 is displayed on the display 180.

[0094] The user can move the remote control device 200 up and down, left and right, and rotate it. The pointer 205 displayed on the display 180 of the display device 100 corresponds to the movement of the remote control device 200. As shown in the diagram, the pointer 205 of such a remote control device 200 moves and is displayed in accordance with its movement in 3D space, so it can be named a "spatial remote control".

[0095] Figure 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.

[0096] Information regarding the movement of the remote control device 200, as detected by 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 then display the pointer 205 in accordance with the calculated coordinates.

[0097] Figure 4(c) illustrates a case where, while a specific button on the remote control device 200 is pressed, the user moves the remote control device 200 away from the display 180. As a result, the selected area on the display 180 corresponding to the pointer 205 is zoomed in and enlarged.

[0098] Conversely, if the user moves the remote control device 200 closer to the display 180, the selected area on the display 180 corresponding to the pointer 205 will be zoomed out and displayed in a reduced size.

[0099] On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 moves closer to the display 180, the selection area is zoomed in.

[0100] Furthermore, when a specific button in the remote control device 200 is pressed, the recognition of up / down and left / right movement is eliminated. That is, when the remote control device 200 moves away from or closer to the display 180, up / down and left / right movement is not recognized, and only forward / backward movement is recognized. When no specific button in the remote control device 200 is pressed, only the pointer 205 moves in accordance with the up / down and left / right movement of the remote control device 200.

[0101] On the other hand, the movement speed and direction of the pointer 205 can correspond to the movement speed and direction of the remote control device 200.

[0102] On the other hand, in this specification, a pointer refers to an object displayed on the display 180 in response to the operation of the remote control device 200. Therefore, objects of various shapes other than the arrow shape illustrated in the drawing are possible with the pointer 205. For example, it may be a concept that includes a point, cursor, prompt, thick border, etc. Furthermore, the pointer 205 can be displayed corresponding to one point on either the horizontal or vertical axis of the display 180, or it can be displayed corresponding to multiple points such as a line or surface.

[0103] Figures 5a to 5c illustrate a light-shielding state according to one embodiment of the present disclosure.

[0104] In one embodiment, the light-shielding state of the display 180 may be determined by the area of ​​the light-shielding region within the entire area of ​​the display 180 where light is blocked. For example, the light-shielding state may be a fully light-shielded state where the entire area of ​​the display 180 is shrouded in light, a partially light-shielded state where a portion of the display 180 is shrouded in light, or an unlight-shielded state where the entire area of ​​the display 180 is not shrouded in light.

[0105] A fully shaded state can be called the first shading state. A partially shaded state can be called the second shading state. An unshaded state can be called either the transparent state, the illuminated state, or the third shading state.

[0106] Figure 5a can show a fully shaded state in which the entire area 500 of the display 180 is blocked from light.

[0107] Figure 5b shows a partially lit state in which, of the entire area 500 of the display 180, a first partial area 501 is illuminated and a second partial area 503 is lit.

[0108] Figure 5c can show the un-obstructed state in which the entire area 500 of the display 180 is illuminated.

[0109] In yet another embodiment of this disclosure, the shading state of the display 180 may include the degree of shading of the entire display 180 or the degree of shading of a portion of the display 180. The degree of shading may be a concept inversely proportional to transparency.

[0110] Figures 6a and 6b illustrate a non-electronic light-shielding method according to one embodiment of the present disclosure, and Figure 6c illustrates an electronic light-shielding method according to yet another embodiment of the present disclosure.

[0111] The light-shielding state of the display 180 can be controlled by a non-electronic light-shielding method or an electronic light-shielding method.

[0112] In one embodiment, a light-shielding film may be provided on one side of the display 180. The light-shielding film can block light that is transmitted into the area of ​​the display 180.

[0113] The light-shielding film may be either a first-type or second-type light-shielding film. The first-type light-shielding film may be a non-electronic light-shielding film, and the second-type light-shielding film may be an electronic light-shielding film. The first type of light-shielding film can be made of any one of the following materials: a polymer film, an opaque film, or a fiber film composed of fibers, but these are merely examples.

[0114] The second type of light-shielding film can be an electronic light-shielding film, such as those used in liquid crystal display (LCD) panels.

[0115] In the case of the non-electronic light-shielding method, the size of the light-shielding area of ​​the display 180 can be adjusted by the physical movement of the first type of light-shielding film.

[0116] In the electronic light-shielding method, the transmittance to an area of ​​the display 180 is electrically controlled, and the light-shielding state of the display 180 can be adjusted. The electronic light-shielding method can also be called the liquid crystal shutter method.

[0117] First, let's explain the non-electronic light-shielding method.

[0118] Referring to Figure 6a, the display device 100 may include a display 180, a side frame 610, and a housing 90. The display 180 can display an image. The side frame 610 may extend around the display 180. The housing 90 may be located below the display 180 and the side frame 610. Alternatively, the housing 90 may be located above, to the left, or below the display 180 and the side frame 610.

[0119] The display 180 may include a first long side LS1, a second long side LS2 opposite the first long side LS1, a first short side SS1 adjacent to the first long side LS1 and the second long side LS2, and a second short side SS2 opposite the first short side SS1.

[0120] On the other hand, for the sake of explanation, it is stated that the lengths of the first and second long sides LS1 and LS2 are longer than the lengths of the first and second short sides SS1 and SS2, but the lengths of the first and second long sides LS1 and LS2 may be approximately the same as, or even longer than, the lengths of the first and second short sides SS1 and SS2.

[0121] The direction aligned with the longer sides LS1 and LS2 of the 180 display can be called the left-right direction. The direction aligned with the shorter sides SS1 and SS2 of the 180 display can be called the up-down direction. The direction perpendicular to the longer sides LS1 and LS2 and the shorter sides SS1 and SS2 of the 180 display can be called the front-back direction.

[0122] The direction in which display 180 displays an image can be called forward z, and the opposite direction can be called backward -z. The first short side SS1 can be called left x, Le. The second short side SS2 can be called right -x, Ri. The first long side LS1 can be called upper y, U. The second long side LS2 can be called lower -y, D.

[0123] The housing 90 may include a light-shielding film, one or more rollers for moving the light-shielding film upwards, and one or more motors for driving the one or more rollers.

[0124] The first type of light-shielding film can be positioned behind the rear surface of the display 180 and can move in the vertical direction of the display 180. The first type of light-shielding film can have an area that can cover the rear surface of the display 180.

[0125] The first type of light-shielding film can be placed on the top surface of the display 180, has the form of a curtain slide, and can move up and down.

[0126] The controller 170 of the display device 100 can control the movement of the first type of light-shielding film by controlling one or more motors located inside the housing 90.

[0127] Referring to Figure 6b, a first type of light-shielding film 620 is shown covering the rear surface of the display 180. The first type of light-shielding film 620 can be pulled out or retracted from the housing 90.

[0128] In Figure 6b, the light-shielding state of the display 180 can be a fully light-shielded state.

[0129] Next, the electronic light-shielding method will be explained with reference to Figure 6c.

[0130] Referring to Figure 6c, a display 180 and a second type of light-shielding film 630 positioned behind the display 180 are shown. The second type of light-shielding film 630 can be a liquid crystal display (LCD) panel.

[0131] The controller 170 of the display device 100 can control the LCD panel 630 to control the transmittance corresponding to a part or the entire area of ​​the display 180.

[0132] The controller 170 or a video driving circuit (not shown) can transmit control signals to the LCD panel 630 to control the arrangement of liquid crystal molecules corresponding to an area of ​​the display 180, thereby adjusting the transmittance to that area. The video driving circuit may be included in the controller 170 or may be a separate component from the controller 170.

[0133] The control signal that controls the arrangement of liquid crystal molecules may be a voltage signal that controls the voltage applied to the liquid crystal layer of the LCD panel 630.

[0134] The LCD panel 630 may include two polarizers, a Thin Film Transistor (TFT), and a liquid crystal layer. Each of the two polarizers can transmit light in one direction and block light in the other direction. The TFT may be a switching element that applies a voltage signal to the liquid crystal layer to control the arrangement of liquid crystal molecules and block them. The liquid crystal molecules in the liquid crystal layer can be arranged according to the voltage signal received from the TFT. Light can be passed through or blocked by the arrangement of the liquid crystal molecules.

[0135] Light can pass through the liquid crystal layer after passing through the first polarizing plate. If the polarization direction of the light is changed in the liquid crystal layer, it can pass through the second polarizing plate. If the polarization direction of the light is changed by the arrangement of the liquid crystals, the amount of light passing through the second polarizing plate can be changed. This allows the transmittance of the LCD panel 630 to be adjusted.

[0136] The video driving circuit can adjust the transparency of a specific area by applying or blocking voltage to only the pixels in that area through electrodes arranged in a matrix configuration on the LCD panel 630.

[0137] The display device 100 can generate light-shielding and non-light-shielding areas by adjusting the transmittance of a specific area of ​​the display 180.

[0138] Figures 7a and 7b illustrate various forms of displays according to embodiments of the present disclosure.

[0139] Referring to Figure 7a, a pixel can include a light-emitting region and a transparent region. In the light-emitting region, RGBW (Red, Green, Blue, White) subpixels can be arranged vertically, and the transparent region, which does not contain subpixels, can be located on the side of the light-emitting region.

[0140] This allows the display 180, which has multiple pixels, to not only display an image but also to transmit light. The display 180 can be called a transparent display panel or a transparent OLED (Organic Light Emitting Diode) panel.

[0141] Referring to Figure 7b, a pixel may include a light-emitting region and a transparent region. Subpixels of RGW (Red, Green, White) or BGW (Blue, Green, White) may be arranged adjacent to each other in the light-emitting region, and the transparent region without subpixels may be located on the side of the light-emitting region.

[0142] As a result, the display 180, which has multiple pixels, can not only display an image but also transmit light. The display 180 can be called a transparent display panel or a transparent OLED panel.

[0143] Figure 8 is a diagram used to describe lighting according to one embodiment of the present disclosure.

[0144] Referring to Figure 8, the display 180 can output screen 301. The display device 100 may further include a cover 300 that surrounds the top, bottom, rear, and sides of the display 180.

[0145] An upper cover 310 located at the top edge of the display 180 may be equipped with one or more lights 311. One or more lights 311 may be connected to the upper cover 310 in a detachable manner.

[0146] Each of the one or more lights 311 may be a light-emitting diode (LED). Each of the one or more lights 311 may be placed at a certain distance from one another.

[0147] Figure 8 shows a configuration in which one or more lights 311 are provided on the upper cover 310, but is not limited to this. For example, one or more lights 311 can be provided on one or more of the upper cover 310, lower cover 320, left cover 330, or right cover 340.

[0148] Each of the one or more lights 311 can emit colored light in the direction in which the image 301 is displayed. Each of the one or more lights 311 can emit colored light in the direction of the lower cover 320.

[0149] The display device 100 can output light having a color corresponding to the image 301 displayed on the display 180. The controller 170 can control one or more lights 311 to output light with RGB values ​​corresponding to a representative color.

[0150] One or more lights 311 may be equipped with a wired communication circuit or a wireless communication circuit for communicating with the controller 170. The controller 170 can transmit control signals to one or more lights 311 that cause them to output light of a representative color. One or more lights 311 can output light of a representative color in response to the received control signals.

[0151] Figures 9 and 10 are flowcharts illustrating the operation method of a display device according to one embodiment of the present disclosure.

[0152] Referring to Figure 9, the display device 100 can confirm the light-shielding state of the display 180 during operation S910. The display device 100 can determine the light-shielding state of the display 180 to be one of the following: a fully shielded state in which the entire area of ​​the display 180 is shielded, a partially shielded state in which a part of the display 180 is shielded, and an unshielded state in which the entire area of ​​the display 180 is not shielded.

[0153] In operation S920, the display device 100 can determine settings related to the output of the screen via the display 180 (hereinafter referred to as screen display settings) based on the light-shielding state of the display 180. Here, the screen display settings may include the intensity of the lighting, whether or not there is background output, the brightness of the screen, and the characteristics of text (e.g., boldness, font, size, etc.) contained on the screen, such as characters, numbers, and symbols.

[0154] For example, if the display device 100 is in a fully shaded state, it can determine the screen display setting to a first display setting corresponding to the fully shaded state. For example, if the display device 100 is not in a fully shaded state, it can determine the screen display setting to a second display setting corresponding to the unshaded state.

[0155] A screen display setting according to one embodiment of this disclosure will be described with reference to Figure 10.

[0156] Referring to Figure 10, the display device 100 can determine in operation S1010 whether the light-shielding state of the display 180 is a fully light-shielded state.

[0157] In operation S1020, the display device 100 can set the intensity of the illumination 311 to a first illumination intensity if the display 180 is in a fully shaded state. Here, the first illumination intensity can mean the basic illumination intensity corresponding to the user setting.

[0158] In operation S1030, if the display 180 is in a fully shaded state, the display device 100 can set the brightness of the screen output via the display 180 to a first screen brightness. Here, the first screen brightness can mean the basic screen brightness corresponding to the user's setting. In this case, the first screen brightness can be changed according to the room's illuminance, the user's setting, etc. The brightness of the screen can also be referred to as the screen's luminance.

[0159] In other words, the illumination intensity corresponding to the first display setting can be the first illumination intensity. Similarly, the screen brightness corresponding to the first display setting can be the first screen brightness. On the other hand, in the first display setting, the text thickness can be set to the first thickness, the text size to the first size, and so on.

[0160] On the other hand, in operation S1040, if the display 180 is not in a fully shaded state, the display device 100 can set the intensity of the illumination 311 to a second illumination intensity. In this case, the second illumination intensity can exceed the first illumination intensity.

[0161] According to one embodiment, the second illumination intensity may be a preset illumination intensity. The second illumination intensity may be restricted from being changed by user settings. For example, the second illumination intensity may be the maximum value relative to the intensity of illumination 311.

[0162] In operation S1050, if the display 180 is not in a fully shaded state, the display device 100 can set the brightness of the screen output via the display 180 to the second screen brightness. In this case, the second screen brightness can exceed the first screen brightness.

[0163] According to one embodiment, the second screen brightness may be a preset screen brightness. The second screen brightness may be restricted from being changed by the user. For example, the second screen brightness may be the maximum value of the screen brightness output via the display 180.

[0164] In other words, the illumination intensity corresponding to the second display setting can be the second illumination intensity. Similarly, the screen brightness corresponding to the second display setting can be the second screen brightness. On the other hand, in the second display setting, the text thickness can be set to a second thickness that exceeds the first thickness, and the text size can be set to a second size that exceeds the first size, and so on.

[0165] Referring again to Figure 9, in operation S930, the display device 100 can output a screen via the display 180 according to the screen display settings. For example, when the light-shielding state of the display 180 is in a fully shaded state, the display device 100 can output a predetermined image via the display 180 according to the first display setting. For example, when the light-shielding state of the display 180 is not in a fully shaded state, the display device 100 can output a predetermined image via the display 180 according to the second display setting.

[0166] Referring to Figure 11a, when the light-shielding state of the display 180 is in a fully light-shielding state, a predetermined video 1100 can be output via the display 180 according to the first display setting.

[0167] In a fully light-shielded state, the light-shielding films 620 and 630 block the light transmitted to the area of ​​the display 180, so the user cannot perceive the space behind the display 180, and therefore the user can clearly perceive only the screen.

[0168] On the other hand, referring to Figure 11b, when the light-shielding state of the display 180 is the non-light-shielding state, a predetermined image 1100 can be output via the display 180 according to the first display setting.

[0169] In this case, if the light transmitted to the area of ​​the display 180 is not blocked by the light-shielding films 620 and 630, the user may perceive the space behind the display 180 along with the screen, which can reduce the visibility of the screen.

[0170] Therefore, the display device 100 can improve the visibility of the screen by increasing the brightness of the screen when the light-shielding state of the display 180 is not a full light-shielding state, compared to when it is a full light-shielding state.

[0171] On the other hand, when the setting for light shielding of the display 180 is changed, the display device 100 can continuously change the setting value for the screen corresponding to the screen display setting. For example, when the setting for light shielding of the display 180 is changed from a fully shielded state to a non-shielded state, the screen brightness can be gradually increased. For example, when the setting for light shielding of the display 180 is changed from a non-shielded state to a fully shielded state, the screen brightness can be gradually decreased.

[0172] Referring again to Figure 9, in operation S940, the display device 100 can perform an operation to prevent burn-in of the display 180 (hereinafter referred to as burn-in prevention operation) in response to the light-shielding state of the display 180. For example, the display device 100 can perform at least one of a plurality of burn-in prevention operations.

[0173] Burn-in can refer to the phenomenon in which a particular image is persistently displayed like an afterimage at a specific location on the display 180. Burn-in can occur particularly in self-emissive displays such as CRTs and OLEDs, where each element constituting the pixel emits light itself, rather than relying on a separate light source such as a backlight unit. Burn-in can occur due to the degradation of the elements constituting the pixel when a particular image is repeatedly displayed or fixed at a specific location on the display 180 over a long period of time.

[0174] According to one embodiment, the display device 100 can perform a first burn-in prevention operation that adjusts the switching of images output via the display 180. For example, the display device 100 can sequentially output multiple images via the display 180 according to a predetermined cycle. When multiple images are output sequentially, burn-in can be prevented because a particular image is not continuously output via the display 180.

[0175] The display device 100 can set the period during which the image output via the display 180 changes (hereinafter referred to as the screen switching period) to the first time when the display 180 is in a fully darkened state. On the other hand, if the display 180 is not in a fully darkened state, the screen switching period can be set to the second time, which is less than the first time.

[0176] When the screen display setting is set to the second display setting, the screen brightness may increase compared to the first display setting. In this case, the higher the brightness of the screen output via display 180, the faster the elements constituting the pixels can degrade. Therefore, by shortening the screen switching cycle in response to the increase in the brightness of the screen output via display 180, burn-in can be effectively prevented.

[0177] According to one embodiment, the display device 100 can perform a second burn-in prevention operation, which involves moving the screen output via the display 180. Here, the second burn-in prevention operation can include a pixel shift operation, an orbit operation, and the like. For example, the display device 100 can move the screen output via the display 180 by a predetermined number of pixels according to a predetermined period. In this case, since the output of each pixel can be changed by moving the screen output via the display 180, burn-in can be prevented.

[0178] The display device 100 can set the period for moving the screen output via the display 180 (hereinafter referred to as the pixel movement period) to the third time when the display 180 is in a fully darkened state. On the other hand, when the display 180 is not in a fully darkened state, the pixel movement period can be set to the fourth time, which is less than the third time. By shortening the pixel movement period in response to an increase in the brightness of the screen output via the display 180, burn-in can be effectively prevented.

[0179] In other words, the display device 100 can perform burn-in prevention operations according to a predetermined cycle. When the light-shielding state of the display 180 is a fully shielded state, the burn-in prevention operation can be performed according to a first cycle. When the light-shielding state of the display 180 is not a fully shielded state, the burn-in prevention operation can be performed according to a second cycle that is shorter than the first cycle. In other words, the predetermined cycle for the burn-in prevention operation can correspond to the light-shielding state of the display 180.

[0180] Referring to Figure 12, the display device 100 can output the first image 1100 via the display 180. For example, the display device 100 can output the first image 1100 as a background screen.

[0181] The display device 100 can output a screen list 1200 containing multiple images. The user can select one of the multiple images included in the screen list 1200. In this case, the display device 100 can output the image selected by the user via the display 180.

[0182] The display device 100 can sequentially output multiple images included in the screen list 1200 according to a predetermined cycle through a first burn-in prevention operation. The screen list 1200 can support the AOD (Always On Display) function. The AOD function is a function in which the display device 100 outputs images via the display 180 using minimal power while minimizing the use of other functions to correspond to a power-off state. In this case, if the light-shielding state of the display 180 is a fully darkened state, the screen switching cycle can be set to the first hour (e.g., 10 minutes).

[0183] Referring to Figure 13a, the display device 100 can change the video output via the display 180 to the second video 1310 according to the screen switching cycle. In this case, if the screen switching cycle is set to the first hour (e.g., 10 minutes), the display device 100 can output the second video 1310 via the display 180 after the first hour (e.g., 10 minutes) has elapsed since the first video 1100 was output.

[0184] On the other hand, when the shading state of display 180 is changed to an unshaded state, the screen switching cycle can be set to the second time interval (e.g., 5 minutes).

[0185] The display device 100 can output a message 1330 corresponding to a change in the screen switching cycle via the display 180. The message 1330 corresponding to the change in the screen switching cycle can be displayed as a pop-up window on the screen output via the display 180. For example, if the shading state of the display 180 is changed from a fully shaded state to an unshaded state, a message 1330 indicating that the screen switching cycle is changed from the first time (e.g., 10 minutes) to the second time (e.g., 5 minutes) can be output.

[0186] Referring to Figure 13b, the display device 100 can change the video output via the display 180 to the third video 1320 according to the screen switching cycle. In this case, if the screen switching cycle is set to the second time (e.g., 5 minutes), the display device 100 can output the third video 1320 via the display 180 after the second time (e.g., 5 minutes) has elapsed since the output of the second video 1310.

[0187] Referring to Figures 14a and 14b, the display device 100 can output a predetermined video 1400 via the display 180. At this time, a predetermined logo corresponding to the content provider can be displayed in a specific area 1410 of the display 180.

[0188] The display device 100 can perform a second burn-in prevention operation to prevent a predetermined logo from being fixedly output to a specific position on the screen display 180. The display device 100 can move the position of the predetermined logo displayed in a specific area 1410 of the display 180 by a preset number of pixels. For example, the position of the predetermined logo can be moved clockwise by a preset number of pixels in a specific area 1410 of the display 180 according to a preset pixel movement cycle.

[0189] When the display 180 is in a fully shaded state, the pixel movement cycle can be set to the third time. On the other hand, when the display 180 is not shaded, the pixel movement cycle can be set to the fourth time, which is shorter than the third time. Therefore, when the display 180 is not shaded, the position of a given logo can move more frequently than when it is in a fully shaded state.

[0190] On the other hand, according to one embodiment, the display device 100 can determine the screen display setting based on the illuminance of the room. For example, if the illuminance of the room is below a predetermined standard, the display device 100 can determine the screen display setting to a first display setting corresponding to a fully shaded state. For example, if the illuminance of the room exceeds a predetermined standard, the display device 100 can determine the screen display setting based on the shading state of the display 180.

[0191] According to one embodiment, the display device 100 can perform burn-in prevention operations based on the illuminance of the room. For example, if the illuminance of the room is below a predetermined standard, the display device 100 can determine a predetermined period related to the burn-in prevention operation to a first period corresponding to a fully shaded state. For example, if the illuminance of the room exceeds a predetermined standard, the display device 100 can determine a predetermined period related to the burn-in prevention operation based on the shading state of the display 180.

[0192] When the indoor illumination is below a certain level, even if the light transmitted to the area of ​​the display 180 is not blocked by the light-shielding films 620 and 630, the user may have difficulty perceiving the space behind the display 180. In other words, when the indoor illumination is below a certain level, the user can clearly perceive only the screen, even if the display 180 is not in a light-shielding state.

[0193] The display device 100 may include a sensor for detecting indoor illuminance. Alternatively, the display device 100 can also determine the illuminance of the indoor space based on data for indoor illuminance received from the outside. For example, the remote control device 200 may include a sensor for detecting indoor illuminance. In this case, the remote control device 200 can transmit data corresponding to the indoor illuminance detected via the sensor to the display device 100.

[0194] As described above, according to at least one embodiment of this disclosure, settings related to the output of video through the transparent display panel can be adjusted according to the light-shielding state of the transparent display panel, thereby improving the visibility of the video.

[0195] Furthermore, according to at least one embodiment of this disclosure, the burn-in prevention process can be optimized according to the light-shielding state of the transparent display panel, thereby effectively preventing burn-in.

[0196] Referring to Figures 1 to 14b, a display device 100 according to one aspect of the present disclosure includes a light-transmitting display panel 180, light-shielding films 620, 630 that block light transmitted through the display panel 180, and a controller 170. The controller 170 checks the light-shielding state of the display panel 180 in the area of ​​the entire area of ​​the display panel 180 that corresponds to the area where the light is blocked, determines a setting related to the output of the screen via the display panel 180 based on the light-shielding state, outputs a predetermined image via the display panel 180 according to the determined setting, and performs a predetermined operation to prevent burn-in of the display panel 180 according to a predetermined period corresponding to the light-shielding state.

[0197] Furthermore, according to one aspect of this disclosure, the controller 170 can output a screen with a first brightness via the display panel 180 if the determined setting is a first setting corresponding to light shielding, and can output a screen with a second brightness exceeding the first brightness via the display panel 180 if the determined setting is a second setting corresponding to light transmission.

[0198] Furthermore, according to one aspect of this disclosure, the controller 170 can determine the predetermined period to be a first period when the light-shielding state corresponds to light shielding, and can determine the predetermined period to be a second period shorter than the first period when the light-shielding state corresponds to light transmission.

[0199] Furthermore, according to one aspect of this disclosure, the controller 170 can perform the predetermined operation of sequentially outputting a plurality of images via the display panel 180 according to the predetermined period.

[0200] Furthermore, according to one aspect of this disclosure, the multiple videos can be compatible with the AOD (Always On Display) function.

[0201] Furthermore, according to one aspect of this disclosure, the predetermined operation can be performed, which involves moving the screen output via the display panel 180 by a predetermined number of pixels according to the predetermined period.

[0202] Furthermore, according to one aspect of this disclosure, the controller 170 can control the light-shielding films 620 and 630 so that light is sequentially blocked or transmitted from one end to the other of the display panel 180 in response to a change in the setting for the light-shielding state, control the display panel 180 so that the brightness of the screen output through the display panel 180 gradually increases in response to a change in the setting for the light-shielding state from light-shielding to light-transmitting, and control the display panel 180 so that the brightness of the screen output through the display panel 180 gradually decreases in response to a change in the setting for the light-shielding state from light-transmitting to light-shielding.

[0203] Furthermore, according to one aspect of the present disclosure, the present invention further includes at least one light source positioned on at least one side of the display panel 180 and outputting light of a predetermined color toward the display panel 180, wherein the controller 170 can control the light source to output light of the predetermined color at a first intensity when the determined setting is a first setting corresponding to light shielding, and to output light of the predetermined color at a second intensity exceeding the first intensity when the determined setting is a second setting corresponding to light transmission.

[0204] Furthermore, according to one aspect of this disclosure, the controller 170 further includes a sensor for detecting the illuminance inside a room, and the controller 170 can determine the setting to a first setting corresponding to shading if the illuminance inside the room is below a predetermined standard, and can determine the setting based on the shading state if the illuminance inside the room exceeds the predetermined standard.
