Description

Display device

[0001] The present disclosure relates to a display device, and more specifically, to a stand-type display device.

[0002] As the information society develops, the demand for display devices is increasing in various forms. In response to this, various display devices such as LCD (Liquid Crystal Display Device), PDP (Plasma Display Panel), ELD (Electroluminescent Display), VFD (Vacuum Fluorescent Display), and OLED (Organic Light Emitting Diode) have recently been researched and are being used.

[0003] An LCD panel is equipped with a TFT substrate and a color substrate facing each other with a liquid crystal layer in between, and can display an image using light provided from a backlight unit.

[0004] An OLED panel can display an image by depositing a self-luminous organic layer on a substrate having a transparent electrode formed thereon.

[0005] Recently, much research has been conducted on display device structures in which the stand is detachable from a head that has a display function.

[0006] The user can attach the stand to the head to watch videos in a stand-type format, or detach the stand from the head to watch videos through the head.

[0007] When a user watches video through the head after detaching the stand, a folio cover covering the head may be used. When the display panel equipped in the head is covered by the folio cover, the screen of the head may be turned off by a magnetic field detected by a Hall sensor.

[0008] However, conventional display devices lacked the capability to detect whether the stand and the head were separated. In this case, when a user mounts the stand onto the head and attaches a remote cable equipped with a magnet to the location of the head's Hall sensor, there is a problem where the head's screen turns off due to the magnetic field detected by the Hall sensor.

[0009] In addition, sound quality and picture quality settings may differ depending on whether the display device is used in stand form or only the head is used as the display device.

[0010] In this case, there is a problem where the user must manually adjust the settings through the settings menu when using the display device in stand form and then detaching the stand to use it as a head type.

[0011] The purpose of the present disclosure may be to prevent a Hall sensor provided in a head from being unnecessarily activated.

[0012] The purpose of the present disclosure may be to disable the function of the Hall sensor when the display device is used in a stand form without using a folio cover.

[0013] The purpose of the present disclosure may be to detect separation or mounting between a stand and a head and to operate a display device with a setting suitable for the detected situation.

[0014] A display device according to one embodiment of the present disclosure includes a head having a display, a sensor used to turn the screen of the display on or off, and a controller, wherein the controller detects whether a stand supporting the head is connected to the head, and when it detects that the stand is connected to the head, it can deactivate the function of the sensor.

[0015] In a method of operation of a display device according to one embodiment of the present disclosure, the display device comprises a head having a display, a sensor used to turn the screen of the display on or off, and a controller, and the method of operation may include the step of detecting whether a stand supporting the head is connected to the head; and the step of deactivating the function of the sensor when the stand is detected to be connected to the head.

[0016] According to an embodiment of the present disclosure, when the stand and the head are connected, the function of the Hall sensor may be deactivated. Accordingly, the problem of the display screen turning off even if the user places the remote control device in a position adjacent to the magnet inside the head may be resolved.

[0017] According to an embodiment of the present disclosure, the setting values ​​of the display device can be automatically optimized depending on whether the stand and the head are connected. Accordingly, the user does not need to perform separate manual operation, and the convenience of using the display device can be greatly improved.

[0119] The connection of the stand (20, 30, 40, 50) to the head (10) may mean that the rotary connector (40) is connected to the head (10). The separation of the stand (20, 30, 40, 50) from the head (10) may mean that the rotary connector (40) is separated from the head (10).

[0120] The controller (170) can determine whether the stand (20, 30, 40, 50) is connected to the head (10) by detecting a change in voltage detected at the ground detection pin.

[0121] This will be explained with reference to FIGS. 7 to 8b.

[0122] FIGS. 7 to 8b are drawings illustrating a method for detecting whether a stand and a head are connected according to an embodiment of the present disclosure.

[0123] Referring to FIG. 7, the base (20) may be equipped with a power board (21). The power board (21) can transmit power supplied from an external power source to the connector (11) of the head (10) through a rotary connector (40).

[0124] The head (10) may include a connector (11) for connection with a stand (20, 30, 40, 50), a charging board (12) for supplying power to a component provided in the head (10), and a main SoC (13). The charging board (12) and the main SoC (13) may be included in a controller (170). The controller (170) may include one or more hardware processors or one or more chips. Each of the charging board (12) and the main SoC (13) may be an example of a hardware processor or chip.

[0125] The connector (11) and the charging board (12) can be connected via a wire, and the charging board (12) and the main SoC (13) can be connected via a wire.

[0126] In one embodiment, the rotary connector (40) and the connector (11) provided on the head (10) can be connected through one or more pogo pins.

[0127] The power board (21) can supply power to the rotary connector (40) through a wire, and the rotary connector (40) can transmit the power supplied from the power board (21) to the connector (11). The connector (11) may include a VCC terminal, a ground terminal, and a ground detection pin (11-1) that receive voltage from the rotary connector (40).

[0128] When the ground terminal of the rotary connector (40) is connected to the ground detection pin (11-1) of the connector (11) of the head (10), the voltage of the ground detection pin (11-1) can be changed from the base voltage of 3.5V to 0V. Accordingly, the voltage detected at the ground detection pin (12-1) of the charging board (12) and the ground detection pin (13-1) of the main SoC (13), respectively, can also be changed from 3.5V to 0V.

[0129] The main SoC (13) can determine that the 3.3V corresponding to the high signal changes to the 0V corresponding to the low signal as the voltage of the ground detection pin (13-1) changes from 3.5V to 0V.

[0130] The main SoC (13) can determine that the stand (20, 30, 40, 50) is connected to the head (10) based on the detection of a low signal.

[0131] When the ground terminal of the rotary connector (40) is disconnected from the ground detection pin (11-1) of the connector (11) of the head (10), the voltage of the ground detection pin (11-1) can be changed from 0V to 3.5V. Accordingly, the voltage detected at the ground detection pin (12-1) of the charging board (12) and the ground detection pin (13-1) of the main SoC (13), respectively, can also be changed from 0V to 3.5V.

[0132] The main SoC (13) can determine that as the voltage of the ground detection pin (13-1) changes from 0V to 3.5V, the 0V corresponding to the low signal changes to 3.3V corresponding to the high signal.

[0133] The main SoC (13) can determine that the stand (20, 30, 40, 50) is separated from the head (10) based on detecting a high signal.

[0134] FIG. 8a is a diagram illustrating an equivalent circuit in which a rotary connector (40) is connected to a head (10), and FIG. 8b is a diagram illustrating an equivalent circuit in which a rotary connector (40) is not connected to a head (10).

[0135] The main SoC (13) can determine that a low signal has been detected when 0V is detected through the ground detection pin (13-1). Based on the detection of the low signal, the main SoC (13) can determine that the stand (20, 30, 40, 50) is connected to the head (10).

[0136] The main SoC (13) can determine that a high signal has been detected when 3.3V is detected through the ground detection pin (13-1). The main SoC (13) can determine that the stand (20, 30, 40, 50) has been separated from the head (10) based on the detection of the high signal.

[0137] Again, Figure 6 is explained.

[0138] When the controller (170) determines that the stand (20, 30, 40, 50) is attached to the head (10) (S603), it can disable the Hall sensor (300) (S605) and operate the display device (1) in a first operation mode (S607).

[0139] The controller (170) can disable the function of the Hall sensor (300) when the stand (20, 30, 40, 50) is attached to the head (10). The controller (170) can cut off the power supplied to the Hall sensor (300) when the stand (20, 30, 40, 50) is attached to the head (10). Accordingly, even if the remote control device (200) is positioned above the Hall sensor (300), the Hall sensor (300) does not operate, so the screen of the display (180) may not turn off.

[0140] When the stand (20, 30, 40, 50) is attached to the head (10), the controller (170) can disable the function of the Hall sensor (300) and set the mode of the display device (1) to a first operation mode.

[0141] The first operation mode may indicate that the setting values ​​of the display device (1) are set to a first set of setting values. The setting values ​​of the display device (1) may include at least one of image quality setting values ​​or sound equalizer setting values.

[0142] Image quality setting values ​​may include white balance, sharpness, and brightness values.

[0143] When the controller (170) determines that the stand (20, 30, 40, 50) is attached to the head (10), the order of the step of deactivating the Hall sensor (300) and the step of operating in the first operation mode may be reversed.

[0144] As such, according to an embodiment of the present disclosure, when the stand (20, 30, 40, 50) and the head (10) are connected, the function of the Hall sensor (300) can be deactivated. Accordingly, the problem of the screen of the display (180) turning off even if the user places the remote control device (200) in a position adjacent to the magnet (310) inside the head (10) can be resolved.

[0145] When the controller (170) determines that the stand (20, 30, 40, 50) is not attached to the head (10) (S603), it can activate the Hall sensor (300) (S609) and operate the display device (1) in a second operation mode (S611).

[0146] The controller (170) can activate the function of the Hall sensor (300) when the stand (20, 30, 40, 50) is separated from the head (10). The controller (170) can supply power to the Hall sensor (300) when the stand (20, 30, 40, 50) is not attached to the head (10). Accordingly, when the folio cover (400) is positioned on top of the Hall sensor (300), the Hall sensor (300) is operated so that the screen of the display (180) can be turned off.

[0147] The controller (170) can set the mode of the display device (1) to a second operation mode while activating the function of the Hall sensor (300) when the stand (20, 30, 40, 50) is separated from the head (10).

[0148] The second operation mode is a mode different from the first operation mode, and may indicate that the setting values ​​of the display device (1) are set to the second set of setting values. The setting values ​​of the display device (1) may include at least one of image quality setting values ​​or sound equalizer setting values.

[0149] When the controller (170) determines that the stand (20, 30, 40, 50) is separated from the head (10), the order of the step of activating the Hall sensor (300) and the step of operating in the second operation mode may be reversed.

[0150] In this way, according to an embodiment of the present disclosure, the setting values ​​of the display device (1) can be automatically optimized depending on whether the stand (20, 30, 40, 50) and the head (10) are connected. Accordingly, the user does not need to perform separate manual operation, and the convenience of using the display device (1) can be greatly improved.

[0151] FIG. 9 is a drawing illustrating the arrangement structure of a magnet and a Hall sensor provided in a head according to one embodiment of the present disclosure.

[0152] Referring to FIG. 9, a component array (900) provided inside the upper part of the head (10) is shown.

[0156] The above controller (170) can activate the function of the sensor when it detects that the stand is separated from the head.

[0157] The above controller (70) can operate the display device in a first operation mode when it detects that the stand is connected to the head, and can operate the display device in a second operation mode when it detects that the stand is separated from the head.

[0158] The first operation mode is a mode for setting the setting values ​​of the display device into a first set of setting values, and the second operation mode is a mode for setting the setting values ​​of the display device into a second set of setting values, and the setting values ​​may include one or more of image quality setting values ​​or sound setting values.

[0159] The sensor is a Hall sensor (300) that detects a magnetic field, and when the controller (170) detects separation from the stand and the head, it can turn off the screen of the display based on the magnetic field generated between the magnet (310) provided in the head and the magnet (410) provided in the folio cover (400) covering the head.

[0160] The magnet (310) provided in the Hall sensor (300) and the head (10) is positioned at the top of the display (180), and the Hall sensor and the magnet provided in the head can be positioned at a predetermined distance from each other.
