[0087] In addition, the voice capturer 290 of the remote control device 200 may capture voice.

[0088] The voice capturer 290 may include at least one microphone and capture voice through the microphone.

[0089] Next describe Figure 4 .

[0090] Figure 4 is a view illustrating an example of using a remote control device according to an embodiment of the present disclosure.

[0091] Figure 4 (a) shows that a pointer 205 corresponding to the remote control device 200 is displayed on the display 180 .

[0092] The user can vertically or horizontally move or rotate the remote control device 200. The pointer 205 displayed on the display 180 of the display device 100 corresponds to the movement of the remote control device 200. Since the corresponding pointer 205 is moved and displayed according to the movement in the 3D space as shown in the figure, the remote control device 200 may be referred to as a spatial remote control device.

[0093] Figure 4 (b) shows that if the user moves the remote control device 200 , the pointer 205 displayed on the display 180 of the display device 100 is moved to the left according to the movement of the remote control device 200 .

[0094] Information about the movement of the remote control device 200 detected by the sensor of the remote control device 200 is transmitted to the display device 100. The display device 100 may calculate the coordinates of the pointer 205 from the information about the movement of the remote control device 200. The display device 100 may display the pointer 205 to match the calculated coordinates.

[0095] Figure 4 (c) shows that the user moves the remote control device 200 away from the display 180 while a specific button in the remote control device 200 is pressed. Therefore, a selected area corresponding to the pointer 205 in the display 180 may be enlarged and displayed in an enlarged size.

[0096] On the other hand, if the user moves the remote control device 200 closer to the display 180, a selection area corresponding to the pointer 205 in the display 180 may be zoomed out and displayed in a reduced size.

[0097] On the other hand, if the remote control device 200 is moved away from the display 180 , the selection area may be reduced, and if the remote control device 200 is moved closer to the display 180 , the selection area may be enlarged.

[0098] In addition, if a specific button in the remote control device 200 is pressed, recognition of vertical or horizontal movement may be excluded. That is, if the remote control device 200 is moved away from or closer to the display 180, upward, downward, leftward or rightward movement may not be recognized, but only forward and backward movement may be recognized. When a specific button in the remote control device 200 is not pressed, only the pointer 205 moves according to the upward, downward, leftward or rightward movement of the remote control device 200.

[0099] In addition, the moving speed or moving direction of the pointer 205 may correspond to the moving speed or moving direction of the remote control device 200 .

[0100] In addition, the pointer in this specification means an object displayed on the display 180 in response to the operation of the remote control device 200. Therefore, in addition to the arrow form shown as the pointer 205 in the figure, various forms of objects are possible. For example, the above concept includes a point, a cursor, a hint, and a thick outline. Then, the pointer 205 can be displayed corresponding to one point of the horizontal axis and the vertical axis on the display 180, and can also be displayed corresponding to multiple points such as a line and a surface.

[0117] The body 570 may be connected to a bracket for fixing the transparent display 500 to a wall surface.

[0118] The controller 170 provided in the body 570 may apply an electric signal to the transparent display panel 510 to control the transmittance of the transparent display panel 510 .

[0119] The body 570 may be located in a partial area of ​​the entire area of ​​the transparent display 500 .

[0120] Figure 6 is a flowchart illustrating a method of operating a display device according to an exemplary embodiment of the present disclosure.

[0121] The display device 100 may include a transparent display 500. The transparent display 500 may be a double-sided display that outputs images from the front and rear sides.

[0122] The transparent display 500 may be referred to as a double-sided display.

[0123] The controller 170 of the display device 100 determines whether the remote control device 200 is located at the front side or the rear side of the double-sided display 500 ( S601 ).

[0124] When viewing an image through the double-sided display 500, the user may be located at the front side or the rear side of the double-sided display 500. Therefore, the remote control device 100 manipulated by the user may also be located at one of the front direction or the rear direction of the double-sided display 500.

[0125] That is, the user and the remote control device 200 may be in the same position (front or back).

[0126] In one embodiment, the controller 170 may detect the direction of the remote control device 200 based on a received signal strength indicator (RSSI). The controller 170 may determine the direction of the remote control device 200 based on a first RSSI between an access point (AP) and the remote control device 200 and a second RSSI between the AP and the display device 100.

[0127] Figure 7 and Figure 8 is a diagram illustrating a process of detecting a direction in which a remote control device is located using RSSI according to an embodiment of the present disclosure.

[0128] Figure 7 and Figure 8 Can be Figure 6 An embodiment of step S601.

[0129] Reference Figure 7 and Figure 8 , assuming that the access point 800 is positioned in front of the double-sided display 500. The access point 800 may be an access point that provides Internet connection. The position of the access point 800 and the position of the double-sided display 500 may be fixed at the time of initial installation.

[0130] The access point 800 may perform wireless communication with the remote control device 200 or the display device 100 through the Wi-Fi standard.

[0131] Reference Figure 7 , the controller 170 of the display apparatus 100 may obtain a first RSSI between the AP 800 and the remote control apparatus 200 and a second RSSI between the AP 800 and the display apparatus 100 ( S701 ).

[0132] In an embodiment, the controller 170 may receive the first RSSI and the second RSSI from the AP 800. The AP 800 may measure the first RSSI and the second RSSI and transmit the measured first RSSI and the second RSSI to the wireless communication interface 173 of the display apparatus 100.

[0133] The wireless communication interface 173 may include Wi-Fi circuitry, but circuitry according to other wireless communication standards may be used.

[0134] In another embodiment, the controller 170 may receive the first RSSI from the remote control device 200 and directly measure the second RSSI itself.

[0135] The controller 170 determines whether a difference between the first RSSI and the second RSSI is a positive (+) value ( S703 ).

[0136] When the positions of the AP 800 and the display device 100 are fixed, the second RSSI may be a reference value for determining the direction in which the remote control device 200 is located. That is, the second RSSI may be a fixed value.

[0137] When the difference between the first RSSI and the second RSSI is a positive (+) value, the controller 170 may determine that the remote control device 200 is located in front of the double-sided display 500 ( S705 ).

[0138] exist Figure 8 In the embodiment, when the remote control device 200 is located in front of the double-sided display 500, since the distance between the remote control device 200 and the AP 800 is smaller than the distance between the display device 100 and the AP 800, the first RSSI may be greater than the second RSSI.

[0139] When the first RSSI is greater than the second RSSI, it may be determined that the remote control device 200 is located in front of the double-sided display 500 .

[0140] Meanwhile, when the difference between the first RSSI and the second RSSI is a negative (−) value according to the relative position between the AP 800 and the display device 100 , it may be determined that the remote control device 200 is located in front of the double-sided display 500 .

[0141] If the difference between the first RSSI and the second RSSI is not a positive (+) value, the controller 170 may determine that the remote control device 200 is located at the rear side of the double-sided display 500 ( S707 ).

[0142] In this state, the controller 170 may detect that the difference between the first RSSI and the second RSSI changes from a positive value to a negative value.

[0143] In this case, the controller 170 may determine that the remote control device 200 has moved from the front side to the rear side of the double-sided display 500 .

[0144] If the controller 170 detects that the difference between the first RSSI and the second RSSI changes from a positive value to a negative value and the negative value is maintained for a certain period of time, the controller 170 may determine that the remote control device 200 moves from the front to the back of the double-sided display 500 .

[0145] In this way, according to the embodiment of the present disclosure, the direction in which the remote control device 200 is located can be detected without complicated manipulation by the user.

[0146] Meanwhile, when the power is turned on, the display device 100 can obtain the direction where the remote control device 200 is located.

[0147] The controller 170 of the display device 100 may receive an IR signal for powering on from the remote control device 200 through the IR circuit 151 (or IR module) of the user interface 150 .

[0148] The IR signal may include a first RSSI between the AP 800 and the remote control device 200 .

[0149] That is, the remote control device 200 may include the pre-acquired first RSSI in a reserved field of the IR signal for powering on.

[0150] Before sending the IR signal for powering on, the remote control device 200 may directly measure the first RSSI or receive the first RSSI from the AP 800 and insert the first RSSI into the IR signal.

[0151] The display apparatus 100 may obtain the first RSSI included in the IR signal by parsing the IR signal for power-on.

[0152] The display device 100 may determine whether the remote control device 100 is located at the front side or the rear side of the double-sided display 500 by using the difference between the first RSSI and the pre-measured second RSSI.

[0153] When the display device 100 receives the IR signal for powering on from the remote control device 200 , the display device 100 may be powered on and recognize the direction in which the remote control device 200 is located at the same time.

[0154] As described above, according to the embodiments of the present disclosure, the direction in which the remote control device 200 is located can be easily obtained only through the operation of the user selecting a button for turning on the power through the remote control device 200 .

[0155] Once again, describe Figure 6 .

[0156] In another embodiment, the controller 170 may obtain the direction in which the remote control device 200 is located based on sensing information measured by a motion sensor included in the display device 100 .

[0157] Fig. 9 and Fig.10 2 is a diagram illustrating a process of detecting a direction of a remote control device through a motion sensor according to an embodiment of the present disclosure.

[0158] Reference Fig. 9 , the controller 170 of the display device 100 may detect the start of use of the remote control device 200 (S900).

[0159] In one embodiment, when the controller 170 receives a change in a sensing value of the gyro sensor 241 provided in the remote control device 200 from the remote control device 200 , the controller 170 may detect the start of use of the remote control device 200 .

[0160] The controller 170 may obtain sensing information through the motion sensor 1000 disposed in front of the double-sided display 500 ( S901 ).

[0161] The motion sensor 1000 may be disposed on the front side of the double-sided display 500. The motion sensor 1000 may be disposed on the upper front surface or the lower front surface of the double-sided display 500.

[0162] The motion sensor 1000 may detect infrared rays emitted by a user located in front of the double-sided display 500 and generate sensing information representing the user's motion based on the detected infrared rays.

[0163] The sensing information may include a user image representing the user's motion.

[0164] The controller 170 may compare the sensing information with pre-stored motion information (S903).

[0165] The controller 170 may include motion information indicating a plurality of motions and sensing information stored in the memory 140. The motion information may include motion images corresponding to a plurality of motions in which the user manipulates the remote control device 200.

[0166] The controller 170 may determine whether a use operation of the remote control device 200 is recognized according to the comparison result (S905).

[0167] The controller 170 may compare the user image and the moving image, and determine that the operation using the remote control device 200 is recognized if there is a moving image having a similarity of a predetermined value or more with the user image.

[0168] Reference Fig.10 , the controller 170 may obtain a user image of a user 1010 manipulating the remote control device 200 through the motion sensor 1000 .

[0169] The controller 170 may compare the obtained user image with the motion images 1031 and 1033 pre-stored in the memory 140 .

[0170] When the similarity between one of the motion images 1031 and 1033 and the user image is equal to or greater than a predetermined value, the controller 170 may determine the user image as an image for manipulating the remote control device 200 .

[0171] When it is determined that the use operation of the remote control device 200 is recognized, the controller 170 may determine that the remote control device 200 is located in the front direction of the double-sided display 500 (S907).

[0172] If the use operation of the remote control device 200 and the value of the gyro sensor received from the remote control device 200 are changed, the controller 170 may recognize that the remote control device 200 is located in the front side direction of the double-sided display 500 .

[0173] After determining that the remote control device 200 is located in the front, the controller 170 may periodically check the use of the remote control device 200 until the gyro sensor value received from the remote control device 200 does not change.

[0174] When it is determined that the use operation of the remote control device 200 is not recognized, the controller 170 may determine that the remote control device 200 is located in the rear direction of the double-sided display 500 (S909).

[0175] If the use operation of the remote control device 200 is not recognized and the value of the gyro sensor received from the remote control device changes, the controller 170 may determine that the remote control device 200 is located in the rear direction of the double-sided display 500 .

[0176] Again, we will describe Figure 6 .

[0177] The controller 170 receives a control signal from the remote control device 200 (S603), and performs an operation according to the control signal according to the determined direction in which the remote control device 200 is located (S605).

[0178] In one embodiment, if the remote control device 200 is located in front of the dual-sided display 500 and a control signal indicating movement of the remote control device 200 is received, the controller 170 may move the pointer 205 (or cursor) in the same direction as the movement direction of the remote control device 200 .

[0179] If it is determined that the remote control device 200 is located at the rear side of the double-sided display 500 and a control signal indicating movement of the remote control device 200 is received, the controller 170 may move the pointer 205 (or cursor) in a direction opposite to the movement direction of the remote control device 200 .

[0180] When it is determined that the remote control device 200 is located at the rear side of the double-sided display 500 , the controller 170 may change the display direction of the graphic element to a direction opposite to the existing direction.

[0181] Hereinafter, an example of controlling the operation of the display device 100 according to the direction in which the remote control device 200 is located will be described.

[0182] FIG. 11A to FIG. 11D is a diagram for explaining an example of changing the moving direction of a cursor by moving the remote control device according to the position of the remote control device.

[0183] exist Fig.11A In the embodiment, the remote control device 200 is located at the front side of the double-sided display 500, and FIG. 11B to FIG. 11D In the embodiment, the remote control device 200 is located at the rear side of the double-sided display 500.

[0184] Reference FIG. 11A to FIG. 11D , the display device 100 may receive a movement signal from the remote control device 200 through wireless communication, and display the cursor 205 and the image 1110 on the double-sided display 500 .

[0185] The wireless communication may be Bluetooth communication, but this is just an example.

[0186] The image 1110 may be a text image including text.

[0187] Reference Fig.11A When the controller 170 receives a movement signal from the remote control device 200 that the remote control device 200 moves from the right direction to the left direction, the controller 170 may move the cursor 205 that moves according to the movement of the remote control device 200 from right to left.

[0188] Reference Fig. 11B If the controller 170 determines that the remote control device 200 is located at the rear side of the double-sided display 500 and receives a movement signal that the remote control device 200 moves from the right direction to the left direction, the controller 170 may move the cursor 205 from left to right.

[0189] The user at the rear side may view the text image 1110 in a left-right reversed state.

[0190] If the remote control device 200 is located at the rear side of the double-sided display 500 , the controller 170 may change one or more of the display direction of the cursor 205 , the shape of the cursor 205 , and the color of the cursor 205 .

[0191] When the remote control device 200 moves from the front to the back of the double-sided display 500 , the controller 170 may change one or more of the display direction of the cursor 205 , the shape of the cursor 205 , and the color of the cursor 205 .

[0192] When the remote control device 200 moves from the front side to the back side of the double-sided display 500, the controller 170 can change the display direction of the image and graphic elements and the display position of the graphic elements. The graphic elements may include one or more of ab icons, menus, cursor 205 and OSD (On Screen Display).

[0193] Reference Fig. 11C If the remote control device 200 is located at the rear side of the double-sided display 500 and receives a movement signal that the remote control device 200 moves from the right to the left, the controller 170 can flip the cursor 205 left and right and display the flipped cursor 205 while moving the cursor 205 from the left to the right.

[0194] When the remote control device 200 is located at the rear side of the double-sided display 500, the controller 170 may flip the display direction of the cursor 205 from left to right, Fig. 11B different.

[0195] If the remote control device 200 is located at the rear side of the double-sided display 500 , the controller 170 may reverse the display direction of the cursor 205 left and right, and move the reversed cursor 205 from the left direction to the right direction.

[0196] Therefore, the user at the back can see the natural movement of the cursor 205 which is flipped left and right.

[0197] Reference Fig.11D If the controller 170 receives a movement signal that the remote control device 200 moves from the right to the left, and the remote control device 200 is located on the rear side of the double-sided display 500, the controller 170 can flip the text image 1110 in the left and right directions and move the flipped cursor 205 from the left to the right.

[0198] Therefore, the user located at the rear can see the text image 1110 flipped in the left-right direction and the natural movement of the cursor 205 .

[0199] Meanwhile, when the remote control device 200 is located at the rear side and a user is detected only at the rear side of the double-sided display 500 , the controller 170 may flip and display both the main image and the graphic element.

[0200] Fig. 12A and Fig. 12B is a diagram for explaining an example of changing a moving direction of a selection window by movement of a remote control device according to a position of the remote control device.

[0201] exist Fig. 12A and Fig. 12B , the double-sided display 500 displays a menu list 1200 including a plurality of menu icons and a selection window 1210 for selecting a menu icon.

[0202] exist Fig. 12A In the embodiment, the remote control device 200 is located in front of the double-sided display 500. Fig. 12B In the embodiment, the remote control device 200 is located at the rear side of the double-sided display 500 .

[0203] Reference Fig. 12A When the controller 170 receives a control signal from the remote control device 200 instructing the remote control device 200 to move from the right direction to the left direction, the controller 170 may move the selection window 1210 from the right direction to the left direction.

[0204] Reference Fig. 12B When the controller 170 receives a control signal from the remote control device 200 instructing the remote control device 200 to move from the right direction to the left direction, the controller 170 may move the selection window 1210 from the left direction to the right direction.

[0205] That is, when the remote control device 200 is operated from the rear side of the double-sided display 500 , the left / right movement is operated opposite to the key manipulation of the remote control device 200 .

[0206] Fig.13A and Fig. 13B is a diagram showing a scene provided when the remote control device is operated from the rear side of the double-sided display.

[0207] Reference Fig.13A , the double-sided display 500 displays the content image 1300. On the rear side of the double-sided display 500, the user is viewing the content image 1300 flipped left and right.

[0208] When it is determined that the remote control device 200 is located at the rear side of the double-sided display 500, the controller 170 may also display a PIP image 1310 corresponding to the content image 1300. The PIP image 1310 may be a left-right flipped image of the content image 1300 having a smaller size than the content image 1300.

[0209] When the controller 170 determines that the user is located at the front and rear sides of the dual-sided display 500 and the remote control device 200 is located at the rear side of the dual-sided display 500 , the controller 170 may also display a PIP image 1310 corresponding to the content image 1300 .

[0210] That is, when users are located at the front and rear sides of the dual-sided display 500 , the user at the front side views the video in the normal direction through the content image 1300 , while the user at the rear side views the video in the normal direction through the PIP image 1310 .

[0211] The controller 170 may detect a user located in front or behind through a motion sensor.

[0212] According to another embodiment of the present disclosure, when the remote control device 200 is located at the rear side of the double-sided display 500, at least one of the contrast or brightness of the graphic element may be adjusted. This may be to compensate for the image quality of the image viewed from the rear, since the image quality of the rear is generally designed to be about 90% of the image quality of the front.

[0213] Reference Fig. 13B , the double-sided display 500 may display a content image 1300 , a menu list 1200 , and a selection window 1210 .

[0214] When the remote control device 200 is located at the rear side of the double-sided display 500, the controller 170 may display the original content image 1300 and reverse the menu list 1200 and the selection window 1210 in the left-right direction.

[0215] That is, when the remote control device 200 is located at the rear side of the double-sided display 500, the controller 170 may display only the graphic elements by flipping in the left and right directions.

[0216] If the controller 170 detects that users A and B are located at the front and rear sides of the double-sided display 500, respectively, and the remote control device 200 is located at the rear side of the double-sided display 500, the controller 170 may display the content image as is, while flipping the menu list 1200 and the selection window 1210 left and right.

[0217] User detection may be performed by a motion sensor.

[0218] If a child is viewing the content image 1300 on the front side of the double-sided display 500 and a parent is manipulating the menu list 1200 of the double-sided display 500 through the remote control device 200 on the rear side of the double-sided display 500, then the Fig. 13B .

[0219] Fig.14 A menu screen is provided for setting whether to flip a main image and graphic elements when a remote control device is located at a rear side of a double-sided display according to an embodiment of the present disclosure.

[0220] The menu screen 1400 may include a menu item for setting whether to flip the left-right direction of the main image and the graphic elements if the remote control device 200 is located at the rear side of the double-sided display 500 .

[0221] The user may set to flip only one of the main image or the graphic element through the menu screen 1400 .

[0222] The user may set not to flip both the main image and the graphic elements through the menu screen 1400 .

[0223] In another embodiment, the user can set the menu screen 1400 to only flip some of the graphic elements. For example, the user can only flip the cursor 205 through the menu screen 1400 and set other elements not to flip.

[0224] Fig.15 is a diagram for explaining a scenario in which a position of a remote control device is predetermined by a motion sensor and a power-on signal is received from the remote control device.

[0225] Reference Fig.15 , even if the power of the display device 100 is not turned on, the motion sensor 1000 may be always activated according to the always-on function.

[0226] The motion sensor 1000 may acquire a user image of the front side of the double-sided display 500 and compare the acquired user image with a pre-stored motion image.

[0227] As a result of the comparison, if the similarity between any one of the pre-stored motion images and the user image is less than a certain value, the motion sensor 1000 may determine that the remote control device 200 is located at the rear side of the double-sided display 500 .

[0228] Thereafter, the controller 170 may receive a power-on signal from the remote control device 200 through the IR module, and according to the received power-on signal, flip the content image 1300, the menu list 1200 and the selection window 1210, and display the flipped content image 1300, the menu list 1200 and the selection window 1210.

[0229] Therefore, a user located at the rear side of the double-sided display 500 can view images and graphic elements in a direction suitable for the user's position simply by manipulating the remote control device 200 to turn on the power of the display device 100 without any additional manipulation.

[0232] The display device 100 may include an IR module 151 under the tempered glass cover 530. The IR module 151 receives an IR signal only from the front side of the double-sided display 500.

[0233] If the remote control device 200 is located at the rear side and the remote control device 200 transmits an IR signal, the IR module 151 cannot receive the IR signal.

[0234] According to an embodiment of the present disclosure, the upper side of the tempered glass cover 530 may include an IR reflection inducing unit 1600 .

[0235] The IR reflection inducing unit 1600 may reflect downward the IR signal received from the remote control device 200. Therefore, the IR signal may pass through the inside of the tempered glass cover 530 and be transmitted to the IR module 151.

[0236] The IR reflection inducing unit 1600 may be made of a material capable of reflecting IR signals (eg, metal such as aluminum, a mirror, or glass).

[0237] In this way, even if the remote control device 200 is located at the rear side of the double-sided display 500, the display device 100 according to the embodiment of the present disclosure can normally receive the IR signal.

[0238] Meanwhile, according to an embodiment of the present disclosure, the memory 140 may store a first key value set corresponding to the case where the remote control device 200 is located at the front side of the double-sided display 500 and a second key value set corresponding to the case where the remote control device 200 is located at the rear side of the double-sided display 500.

[0239] If the remote control device 200 is located at the front side of the double-sided display 500 , the first key value set may include key values ​​corresponding to functions of the display device 100 corresponding to a control signal received from the remote control device 200 .

[0240] If the remote control device 200 is located at the rear side of the double-sided display 500 , the second key value set may include key values ​​corresponding to functions of the display device 100 corresponding to a control signal received from the remote control device 200 .

[0241] If the controller 170 receives a control signal for moving the cursor 205 or the selection window 1210 from the remote control device 200, the controller 170 may control the moving direction of the cursor 205 or the selection window 1210 based on the stored first key value set or second key value set.

[0242] According to an embodiment of the present disclosure, the above method can be implemented as a processor-readable code in a medium having a program recorded thereon. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc.
