[0108] Additionally, the microphone (290) of the remote control device (200) can acquire voice.
[0109] A plurality of microphones (290) may be provided.
[0110] Next, Figure 4 is described.
[0111] Figure 4 shows an example of utilizing a remote control device according to an embodiment of the present invention.
[0112] Figure 4 (a) illustrates that a pointer (205) corresponding to a remote control device (200) is displayed on a display (180).
[0113] The user can move or rotate the remote control device (200) up and down, left and right. The pointer (205) displayed on the display (180) of the display device (100) corresponds to the movement of the remote control device (200). This remote control device (200) can be called a space remote control because, as shown in the drawing, the pointer (205) moves and is displayed according to the movement in 3D space.
[0114] Figure 4 (b) illustrates that when a user moves the remote control device (200) to the left, the pointer (205) displayed on the display (180) of the display device (100) also moves to the left correspondingly.
[0115] Information about the movement of the remote control device (200) detected through the sensor of the remote control device (200) is transmitted to the display device (100). The display device (100) can calculate the coordinates of the pointer (205) from the information about the movement of the remote control device (200). The display device (100) can display the pointer (205) to correspond to the calculated coordinates.
[0116] Figure 4 (c) illustrates a case where a user moves the remote control device (200) away from the display (180) while pressing a specific button within the remote control device (200). As a result, a selection area within the display (180) corresponding to the pointer (205) can be zoomed in and displayed in an enlarged manner.
[0117] Conversely, when the user moves the remote control device (200) closer to the display (180), the selection area within the display (180) corresponding to the pointer (205) may be zoomed out and displayed in a reduced size.
[0118] Meanwhile, when the remote control device (200) moves away from the display (180), the selection area may be zoomed out, and when the remote control device (200) moves closer to the display (180), the selection area may be zoomed in.
[0119] Additionally, when a specific button within the remote control device (200) is pressed, recognition of up, down, left, and right movements may be excluded. That is, when the remote control device (200) moves away from or toward the display (180), up, down, left, and right movements may not be recognized, and only forward and backward movements may be recognized. When a specific button within the remote control device (200) is not pressed, only the pointer (205) moves in accordance with the up, down, left, and right movements of the remote control device (200).
[0120] Meanwhile, the movement speed or movement direction of the pointer (205) can correspond to the movement speed or movement direction of the remote control device (200).
[0121] Meanwhile, the pointer in this specification refers to an object displayed on the display (180) in response to the operation of the remote control device (200). Accordingly, objects of various shapes other than the arrow shape illustrated in the drawing can be used as the pointer (205). For example, the pointer may be a concept including a point, a cursor, a prompt, a thick outline, etc. In addition, the pointer (205) may be displayed corresponding to one point on the horizontal or vertical axis on the display (180), or may be displayed corresponding to multiple points such as lines or surfaces.
[0122] Meanwhile, the display device (100) according to the embodiment of the present disclosure may be provided with a case (500) for protecting the display (180).
[0123] The operation mode of the display device (100) can be controlled according to the opening and closing of the case (500).
[0124] In relation to this, it is explained with reference to Fig. 5.
[0125] FIG. 5 is a drawing for explaining the opening and closing of a case according to an embodiment of the present disclosure.
[0126] The display device (100) may include a display (180) and a case (500).
[0127] The case (500) may include some or all of the cover (510), the coupling portion (520), and the storage portion (530).
[0128] The cover (510) can protect the front of the display (180). The cover (510) can include a magnet (300).
[0129] The cover (510) can be connected to the storage unit (530) through the connecting unit (520).
[0130] A display (180) can be stored in the storage unit (530). The storage unit (530) can protect the remaining surfaces of the display (180) except for the front.
[0131] The display (180) may include a display panel (181) on which an image is displayed and a bezel (182). The display (180) may include a Hall sensor (400). The Hall sensor (400) may be placed on the bezel (182). Depending on the embodiment, the Hall sensor (400) may also be placed on the display panel (181).
[0132] Meanwhile, the magnet (300) can be arranged to overlap vertically with the hall sensor (400) provided in the display (180) when the case (500) is closed.
[0133] For example, the magnet (300) may be placed in the sensing area (p) so as to vertically overlap with the Hall sensor (400) when the cover (510) covers the display (180).
[0134] The Hall sensor (400) can detect the magnet (300) by vertically overlapping with the magnet (300). The display device (100) can determine that the case (500) is closed when the Hall sensor (400) detects the magnet (300). In addition, the display device (100) can determine that the case (500) is open when the Hall sensor (400) does not detect the magnet (300). That is, the controller (180) can detect the opening and closing of the case (500) through the Hall sensor (400).
[0135] In summary, the controller (180) can obtain whether the case (510) is opened or closed based on whether the magnet (300) provided in the cover (510) is detected.
[0136] The cover (510) or case (500) having a magnet (300) may be a folio cover or folio case.
[0137] Next, the operation mode of the display device (100) according to the opening and closing of the case (500) will be described with reference to FIGS. 6 and 7.
[0138] Figure 6 is a drawing for explaining the operating mode of the display device when the case is closed.
[0139] The Hall sensor (400) can output a HIGH signal to the controller (180) when it does not detect the magnet (300). The Hall sensor (400) can include a Hall IC.
[0140] When the controller (180) obtains a HIGH signal, it can determine that the case (500) is open. Then, the controller (180) can turn on the display (180) and the speaker (185). The controller can be implemented in the form of a SoC (System on Chip).
[0141] As the display (180) and speaker (185) are turned on, the display device (100) can operate in an operation mode that outputs both images and sound.
[0142] Figure 7 is a drawing for explaining the operating mode of the display device when the case is open.
[0143] The Hall sensor (400) can output a LOW signal to the controller (180) when it detects a magnet (300). The Hall sensor (400) can include a Hall IC.
[0144] When the controller (180) obtains a LOW signal, it can determine that the case (500) is closed. Then, the controller (180) can turn off the display (180) and the speaker (185). The controller (180) can turn off the speaker (185) by turning off the system of the display device (100). The controller can be implemented in the form of a SoC (System on Chip).
[0145] As the display (180) and speaker (185) are turned off, the display device (100) can operate in an operation mode that does not output either images or sound.
[0146] The display device (100) as described in FIGS. 5 to 7 can detect the opening and closing of the case (500) using a single hall sensor (400) and a magnet (300) fixedly arranged on the cover (510). Accordingly, the display device (100) cannot help but turn off both the display (180) and the system when the case (500) is closed.
[0147] Accordingly, the present disclosure seeks to move at least one magnet (300) or at least one hall sensor (400) and turn off only the display (180) depending on the position of the sensor (400) when the case (500) is closed.
[0148] Meanwhile, turning off the display (180) may mean stopping the supply of power to the display (180). Additionally, turning off the display (180) may mean stopping the display of images through the display (180).
[0149] First, an exemplary method for moving a magnet (300) will be described with reference to FIGS. 8 to 11.
[0150] Figure 8 is a drawing for explaining the horizontal movement of the magnet provided in the cover.
[0151] A sensing range (p) may be formed in the cover (510). The sensing range (p) may refer to a range in which the sensor (400) can recognize the magnet (300). The sensor (400) may be included in a Hall PCB placed in the display (180) or an area adjacent to the display (180).
[0152] The sensing range (p) can be formed so that at least a portion thereof overlaps the sensor (400) in the vertical direction.
[0153] The magnet provided in the cover (510) can move horizontally into or out of the sensing range (p).
[0154] Fig. 9 is a drawing showing an example of a member provided in a cover to move a magnet in a horizontal direction.
[0155] The cover (510) may be provided with a slide switch (511) for moving the magnet (300) in a vertical direction.
[0156] The slide switch (511) may be coupled with a magnet (300). For example, the magnet (300) may be coupled to a coupling portion (511-1) of the slide switch (511). The coupling portion (511-1) may move in accordance with the movement of the slider (511-2). For this purpose, the coupling portion (511-1) may be coupled with the slider (511-2).
[0157] The slider (511-2) can move along the groove (511-3) formed in the slide switch (511).
[0158] The Hall sensor (400) can detect the magnet (300) when the slider (511-2) moves to a position where it overlaps with the magnet in the vertical direction, and may not detect the magnet (300) when it moves to a position where it does not overlap with the slider (511-2) in the vertical direction.
[0159] Figure 10 is a drawing for explaining the vertical movement of a magnet provided in a cover.
[0160] The sensing range (p) may be formed horizontally on the same plane as the cover (510), but may also be formed vertically to the cover (510).
[0161] The sensing range (p) formed in the vertical direction may be a range in which the Hall sensor (400) can sense a magnet (300) spaced vertically from the Hall sensor (400).
[0162] The magnet provided in the cover (510) can move vertically into or out of the sensing range (p).
[0163] Fig. 11 is a drawing showing an example of a member provided on a cover to move a magnet in a vertical direction.
[0164] The cover (510) may be provided with a push-pull switch (512) for moving the magnet (300) in a vertical direction.
[0165] A magnet (300) may be inserted into the interior of the push-pull switch (512). Accordingly, when the push-pull switch (512) is pushed, the magnet (300) may move within a sensing range (p) formed in a vertical direction, and when the push-pull switch (512) is released, the magnet (300) may move outside the sensing range (p) formed in a vertical direction.
[0166] Accordingly, the Hall sensor (400) can detect the magnet (300) when the push-pull switch (512) is pushed, and may not detect the magnet (300) when the push-pull switch (512) is released.
[0167] In summary of FIGS. 8 to 11, the cover (510) may include at least one magnet (300) and a member for moving at least one magnet (300) in a horizontal or vertical direction. In addition, the member for moving the magnet (300) in a horizontal direction may be a slide switch (511). In addition, the member for moving the magnet (300) in a vertical direction may be a push-pull switch (512).
[0168] Meanwhile, the structure and method for moving the magnet (300) as described in FIGS. 8 to 11 can be equally applied to moving the Hall sensor (400). In addition, the method for moving the magnet (300) as described in FIGS. 8 to 11 is merely exemplary, and the present disclosure can utilize various types of members to move the magnet (300) or the Hall sensor (400).
[0169] Next, the operation of a display device according to an embodiment of the present disclosure will be described with reference to FIG. 12.
[0170] FIG. 12 is a flowchart for explaining the operation of a display device according to an embodiment of the present disclosure.
[0171] The controller (180) can periodically obtain the output of the Hall sensor (400) when the display device (100) is powered on (S101) (S103).
[0172] The controller (180) can turn on the display (180) and the system as the display device (100) is powered on. When the system is turned on, the display device (100) can perform various functions, such as outputting sound, activating a voice recognition function, or activating a network connection.
[0173] The output of the Hall sensor (400) may vary depending on whether the Hall sensor (400) detects the magnet (300). For example, the Hall sensor (400) may output a LOW signal if it detects the magnet (300), and may output a HIGH signal if it does not detect the magnet (300).
[0174] The controller (180) can obtain whether the output of the hall sensor (400) has changed (S105).
[0175] If the controller (180) determines that the output of the Hall sensor (400) has not changed, it can continue to acquire the output of the Hall sensor (400) (S106).
[0176] The controller (180) can maintain the operating state of the display device (100) and continue to acquire the output of the Hall sensor (400) when it obtains that the output of the Hall sensor (400) has not changed.
[0177] When the controller (180) obtains that the output of the hall sensor (400) has changed, it can obtain operation mode data (S107).
[0178] The operation mode data may be data including the operation mode of the display device (100) according to the output of the Hall sensor (400). The operation mode data may be data including a GPIO (General Purpose Input / Output) table value.
[0179] For example, the operating mode data may include data mapping the first output and the second output to the operating mode. The first output may be the output of the first Hall sensor (410), and the second output may be the output of the second Hall sensor (420).
[0180] The operation mode data may include first data mapping a first operation mode in which the first output is LOW, the second output is LOW, and the display (180) and the system are turned off, second data mapping a second operation mode in which the first output is HIGH, the second output is LOW, and the display (180) is turned off and the voice recognition function of the system is turned on, third data mapping a third operation mode in which the first output is LOW, the second output is HIGH, and the display (180) is turned off and the speaker output of the system is turned on, and fourth data mapping a fourth operation mode in which the first output is HIGH, the second output is HIGH, and the display (180) and the system are turned on.
[0181] Table data may be data pre-stored in the display device (100). Furthermore, the table data may be changed based on user input. Furthermore, the table data may be data obtained from a server.
[0182] The controller (180) can change the operation mode of the display device (100) based on table data (S109).
[0183] For example, if the controller (180) obtains the first output as LOW and the second output as HIGH, the controller (180) can obtain the third data from the table data. Accordingly, the controller (180) can change the operation mode of the display device (100) to the third operation mode.
[0184]
[0185] Next, the arrangement of the magnet (300) and the Hall sensor (400) according to the embodiment of the present disclosure will be described with reference to FIGS. 13 to 15.
[0186] Figure 13 is a drawing showing one magnet arranged on the cover.
[0187] The cover (510) may include a single magnet (300). The magnet (300) may move within the area where the cover (510) is formed. A sensing area (p) may be formed in the cover (510). The hall sensor (400) may detect the magnet (400) when the magnet is positioned in the sensing area (p) when the case (500) is closed. The sensing area (p) may include at least a portion of an area that vertically overlaps the hall sensor (400) when the case (500) is closed.
[0188] The sensing region (p) may include a first sensing region (p1) and a second sensing region (p2). The first sensing region (p1) may be a region in which the first Hall sensor (410) can detect the magnet (300), and the second sensing region (p2) may be a region in which the second Hall sensor (420) can detect the magnet (300).
[0189] The controller (180) can change the operating mode of the display device (100) based on which of the first hall sensor (410) and the second hall sensor (420) detects the magnet (300).
[0190] For example, the controller (180) can turn off both the display (180) and the system when the first hall sensor (410) detects the magnet (300), and can turn off the display (180) and turn on the system when the second hall sensor (420) detects the magnet (300).
[0191] A display device (100) such as FIG. 13 can change the operation mode of the display device (100) by using the arrangement of one magnet (300).
[0192] Meanwhile, a plurality of magnets (300) may be arranged on the cover (510). In this regard, a description will be given with reference to FIG. 14.
[0193] Figure 14 is a drawing showing two magnets arranged on the cover.
[0194] The cover (510) may include a plurality of magnets (300). For example, the cover (510) may include two magnets (300) as illustrated in FIG. 14. Each of the plurality of magnets (300) may move within the area in which the cover (510) is formed.
[0195] When two magnets (300) are placed on the cover (510), the change in the operation mode of the display device (100) according to the Hall sensor (400) may be the same as described in step S109 of FIG. 12.
[0196] Since a display device (100) such as FIG. 14 uses two or more magnets (300), it has the advantage of being able to provide a more diverse and detailed operating mode of the display device (100) when the case (510) is closed.
[0197] Meanwhile, the type of display (180) included in the display device (100) may be diverse, such as an LED display or an OLED display. That is, the type of display device (100) according to the embodiment of the present disclosure may be diverse, such as an LED display device or an OLED display device.
[0198] In relation to this, a method for changing the operation mode of the display device (100) depending on the type of the display device (100) is described.
[0199] Below, the Hall IC can perform the function of a Hall sensor (400), and the main SoC can perform the function of a controller (180).
[0200] FIG. 15 is a block diagram illustrating a method for changing an operation mode of an LED display device according to an embodiment of the present disclosure.
[0201] FIG. 15a is a block diagram of a case where the operation mode of the display device (100) is changed to an operation mode where the display (180) is turned off and the system is turned on, and FIG. 15b is a block diagram of a case where the operation mode of the display device (100) is changed to an operation mode where both the display (180) and the system are turned off.
[0202] Referring to FIG. 15a, the main SoC can turn off the LED driver by receiving an LED driver output signal while it is turned on based on a signal received from the Hall IC. Accordingly, image display through the display (180) is stopped, and the remaining functions except for image display through the display (180) can be performed. For example, since the main SoC is turned on, the display device (100) can output sound.
[0203] Referring to FIG. 15b, the main SoC may turn off the LED driver based on a signal received from the Hall IC. Furthermore, the main SoC may also be turned off. Accordingly, all functions of the display device (100) may be interrupted. Alternatively, the display device (100) may be powered off.
[0204] FIG. 16 is a block diagram illustrating a method for changing an operation mode of an OLED display device according to an embodiment of the present disclosure.
[0205] Referring to FIG. 16a, the main SoC can transmit pixel data to the OLED panel while it is turned on based on a signal received from the Hall IC. The OLED panel can display an image based on the pixel data. The main SoC can transmit pixel data consisting only of black to the OLED panel, thereby stopping the image display through the display (180).
[0206] Referring to FIG. 16b, the main SoC can turn off the OLED panel based on a signal received from the Hall IC. Furthermore, the main SoC can also be turned off. Accordingly, all functions of the display device (100) can be stopped. Alternatively, the display device (100) can be powered off.
[0207] 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.
[0208] 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.
