Accordingly, the terms "module" and "part" may be used interchangeably.

[0066] FIG. 1 is a drawing illustrating an image display device according to one embodiment of the present disclosure.

[0071] Meanwhile, the display (180) in the image display device (100) according to one embodiment of the present disclosure may be rotatable.

[0072] For example, the display (180) in the image display device (100) can be rotated from a horizontal mode with an aspect ratio of Wa:Wb to a vertical mode with an aspect ratio of Wb:Wa.

[0073] As another example, the display (180) in the image display device (100) can be rotated from a vertical mode with an aspect ratio of Wb:Wa to a horizontal mode with an aspect ratio of Wa:Wb.

[0074] Meanwhile, an image display device (100) according to one embodiment of the present disclosure may be connected via a wired connection or wirelessly with a peripheral electronic device such as an external device (1200).

[0083] The tuner unit (110) selects an RF (Radio Frequency) broadcast signal corresponding to a channel selected by the user or all previously stored channels among the RF broadcast signals received through an antenna (not shown). Additionally, it converts the selected RF broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

[0084] For example, if the selected RF broadcast signal is a digital broadcast signal, it is converted into a digital IF signal (DIF), and if it is an analog broadcast signal, it is converted into an analog baseband video or audio signal (CVBS / SIF). That is, the tuner unit (110) can process a digital broadcast signal or an analog broadcast signal.

Additionally, the storage unit (140) may store information regarding a predetermined broadcast channel through a channel memory function such as a channel map.

[0097] Although an embodiment in which the storage unit (140) of FIG. 2 is provided separately from the signal processing device (170) is illustrated, the scope of the present disclosure is not limited thereto. The storage unit (140) may be included within the signal processing device (170).

[0098] The user input interface unit (150) transmits a signal input by the user to the signal processing device (170) or transmits a signal from the signal processing device (170) to the user.

[0099] For example, user input signals such as power on / off, channel selection, and screen settings can be transmitted / received from a remote control device (200), user input signals input from local keys (not shown) such as a power key, channel key, volume key, and setting value can be transmitted to a signal processing device (170), user input signals input from a sensor unit (not shown) that senses a user's gesture can be transmitted to a signal processing device (170), or signals from the signal processing device (170) can be transmitted to a sensor unit (not shown).

This will be described later with reference to FIG. 3.

[0105] In addition, the signal processing device (170) can control the overall operation within the image display device (100). For example, the signal processing device (170) can control the tuner unit (110) to control the selection (tuning) of an RF broadcast corresponding to a channel selected by the user or a pre-stored channel.

[0106] Additionally, the signal processing device (170) can control the image display device (100) by means of a user command or internal program input through the user input interface unit (150).

[0109] Meanwhile, the signal processing device (170) can recognize the user's location based on an image captured by a shooting unit (not shown). For example, it can determine the distance (z-axis coordinate) between the user and the image display device (100). In addition, it can determine the x-axis coordinate and y-axis coordinate within the display (180) corresponding to the user's location.

[0110] The display (180) generates a driving signal by converting a video signal, data signal, OSD signal, control signal processed by a signal processing device (170) or a video signal, data signal, control signal, etc. received from an external device interface unit (130).

Additionally, it may further include a data processing unit (not shown).

[0126] The demultiplexer (310) demultiplexes the input stream. For example, if an MPEG-2 TS is input, it can be demultiplexed to separate it into video, audio, and data signals. Here, the stream signal input to the demultiplexer (310) may be a stream signal output from the tuner (110), the demodulator (120), or the external device interface (130).

[0127] The image processing unit (320) can perform signal processing on the input image. For example, the image processing unit (320) can perform image processing on the image signal demultiplexed from the demultiplexing unit (310).

[0128] To this end, the image processing unit (320) may include an image decoder (325), a scaler (335), an image quality processing unit (635), an image encoder (not shown), a graphics processing unit (340), a frame rate conversion unit (350), and a formatter (360), etc.

In particular, such a pointer can be generated in a pointing signal processing unit, and the graphics processing unit (240) may include such a pointing signal processing unit (not shown). Of course, it is also possible for the pointing signal processing unit (not shown) to be provided separately rather than being provided within the graphics processing unit (240).

[0137] The frame rate converter (FRC) (350) can convert the frame rate of the input video. Meanwhile, the frame rate converter (350) can also output the video as is without separate frame rate conversion.

[0138] Meanwhile, the formatter (360) can convert the format of the input video signal into a video signal for display on a display and output it.

[0139] In particular, the formatter (360) can change the format of the video signal to correspond to the display panel.

[0140] Meanwhile, the formatter (360) may change the format of the video signal.

[0141] The processor (330) can control the overall operation within the image display device (100) or the signal processing device (170).

[0142] For example, the processor (330) can control the tuner (110) to select (Tuning) an RF broadcast corresponding to a channel selected by the user or a pre-stored channel.

[0145] Additionally, the processor (330) can control the operation of the demultiplexer (310), image processing unit (320), etc., within the signal processing device (170).

[0146] Meanwhile, the audio processing unit (370) within the signal processing device (170) can perform voice processing of the demultiplexed voice signal. To this end, the audio processing unit (370) may be equipped with various decoders.

[0152] FIG. 4a is a diagram illustrating a control method of the remote control device of FIG. 2.

[0153] As illustrated in (a) of FIG. 4a, a pointer (205) corresponding to the remote control device (200) is displayed on the display (180).

[0154] The user can move or rotate the remote control device (200) up and down, left and right ((b) of FIG. 4a), and forward and backward ((c) of FIG. 4a). The pointer (205) displayed on the display (180) of the image display device corresponds to the movement of the remote control device (200). Since the pointer (205) of the remote control device (200) moves and is displayed according to the movement in 3D space as shown in the drawing, it can be named a spatial remote control or a 3D pointing device.

[0155] Figure 4a (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 image display device also moves to the left in response.

[0156] Information regarding the movement of the remote control device (200) detected through the sensor of the remote control device (200) is transmitted to the image display device. The image display device can calculate the coordinates of the pointer (205) from the information regarding the movement of the remote control device (200). The image display device can display the pointer (205) to correspond to the calculated coordinates.

[0157] Figure 4a (c) illustrates a case where, while pressing a specific button within the remote control device (200), the user moves the remote control device (200) away from the display (180). By doing so, the selected area within the display (180) corresponding to the pointer (205) can be zoomed in and enlarged. Conversely, when the user moves the remote control device (200) closer to the display (180), the selected area within the display (180) corresponding to the pointer (205) can be zoomed out and reduced. Meanwhile, when the remote control device (200) moves away from the display (180), the selected area is zoomed out, and when the remote control device (200) moves closer to the display (180), the selected area may be zoomed in.

[0158] Meanwhile, when a specific button within the remote control device (200) is pressed, recognition of up-down and left-right movement may be excluded. That is, when the remote control device (200) moves away from or closer to the display (180), up-down, left-right movement is not recognized, and only forward-backward movement is recognized. When the specific button within the remote control device (200) is not pressed, only the pointer (205) moves according to the up-down, left-right movement of the remote control device (200).

[0159] Meanwhile, the movement speed or direction of movement of the pointer (205) can correspond to the movement speed or direction of movement of the remote control device (200).

[0238] Meanwhile, the charging / discharging board (630) may further include a second interface (634) that supplies voltage or current to the internal battery (BTA) during the charging mode of the internal battery (BTA) and receives voltage or current during the discharging mode of the internal battery (BTA), and a switching device (636) that performs switching to supply voltage or current from the second interface (610) to the second interface (634).

[0239] Meanwhile, an image display device (100) according to one embodiment of the present disclosure may further include a DC / DC converter (644) electrically connected to a first port (PT1).

[0240] Meanwhile, the DC / DC converter (644) can be connected between the first port (PT1) of the second interface (610) and the switch (647).

[0241] Meanwhile, the DC / DC converter (644) can lower the level of the first DC voltage (Vm) received through the first port (PT1) in sink mode and supply the lowered DC voltage (5V_TYPE-C) to the power controller (620) via the switch (647).

[0242] For example, the DC / DC converter (644) can reduce the level of the first DC voltage (Vm) of approximately 5 to 20 V and supply a voltage of approximately 5 V to the power controller (620). Accordingly, the power controller (620) can be operated stably based on the DC voltage from the external device (1200).

[0243] Meanwhile, the switch (647) may supply a level-converted DC voltage (5V_NORMAL) based on the internal battery (BTA) to the power controller (620) when the first DC voltage (Vm) is not supplied through the second interface (610).

[0244] Meanwhile, the DC voltage (5V_TYPE-C) output from the DC / DC converter (644) can be input to the signal processing device (170).

[0245] At this time, the signal processing device (170) can receive a USB-C_CHG_DET signal related to the sink mode operation based on the DC voltage (5V_TYPE-C).

[0246] That is, the signal processing device (170) can determine that the operation is in sync mode when the level of the USB-C_CHG_DET signal corresponding to the DC voltage (5V_TYPE-C) is high.

[0247] Meanwhile, the power controller (620) is electrically connected to multiple ports (PT2 to PT5) of the second interface (610) and can receive signals from multiple ports (PT2 to PT5) of the second interface (610).

[0248] For example, the power controller (620) can receive voltage information or current information of an external device (1200) through the second port (PT2) of the second interface (610).

[0249] As another example, the power controller (620) can receive a video signal (Svd) through the fourth port (PT4) or fifth port (PT5) of the second interface (610) in display mode and transmit the video signal (Svd) to the signal processing device (170).

[0250] Meanwhile, the power controller (620) may have a plurality of ports for transmitting or receiving signals with the signal processing device (170).

[0251] For example, the power controller (620) may be equipped with a VMON port for receiving a TYPE-C_VBUS signal, an MGPIO2 port for transmitting a TYPE-C_CC_DET signal, a GPIO4 port for transmitting an ALT_MODE_NOTICE signal, an I2C_EN / GPIO10 port for transmitting a 5V_USB-C_EN signal, an I2C_INT / GPIO9 port for transmitting a 65W_USB-C_EN signal, an IMON port for transmitting a 100W_USB-C_EN signal, a LOC_PWR_MON port for transmitting a TYPE-C_VBUS_DISCHARGE signal, etc.

[0252] Meanwhile, the TYPE-C_VBUS signal can correspond to a signal input to the first port (PT1) of the second interface (610) in source mode.

[0253] Meanwhile, the power controller (620) can output a high-level 5V_USB-C_EN signal in source mode, and the load switch (645) can be turned on based on the 5V_USB-C_EN signal.

[0254] Meanwhile, the power controller (620) can determine a first sink mode operation or a second sink mode operation during a sink mode based on voltage information or current information of an external device (1200).

[0255] For example, the power controller (620) may output a high-level 65W_USB-C_EN signal for a first sink mode operation based on 65W (20V / 3.25A) or a high-level 100W_USB-C_EN signal for a second sink mode operation based on 100W (20V / 5A), based on voltage information or current information of the external device (1200).

[0256] Meanwhile, the power controller (620) can output a high-level TYPE-C_VBUS_DISCHARGE signal for discharging TYPE-C_VBUS.

[0257] Meanwhile, between the power controller (620) and the signal processing device (170), a converter (642) for converting a display signal or video signal (Svd) into an HDMI signal in display mode may be further included.

[0258] Meanwhile, the signal processing device (170) can reset the converter (642) by outputting a reset signal (RESET_N).

[0259] Meanwhile, an image display device (100) according to one embodiment of the present disclosure may further include a load switch (645) electrically connected to a first port (PT1) of a second interface (610).

[0260] Meanwhile, an image display device (100) according to one embodiment of the present disclosure may further include a barrier diode connected between a load switch (645) and a first port (PT1) of a second interface (610).

[0261] Meanwhile, the load switch (645) is turned off in sink mode. Accordingly, the barrier diode and the first port (PT1) of the second interface (610) are electrically isolated.

[0262] Meanwhile, the load switch (645) is turned on in source mode and can supply a third DC voltage (Vn) to the first port (PT1) based on the conduction of the barrier diode. Accordingly, in source mode, a DC voltage can be stably supplied to an external device (1200).

[0263] Meanwhile, the second interface (610) can supply a first DC voltage (Vm) received through the first port (PT1) in sync mode to the charge / discharge board (630). Accordingly, the internal battery (BTA) can be easily charged through the sync mode.

[0264] Meanwhile, the charging / discharging board (630) may include a DC voltage input terminal (632), a second interface (634) that supplies voltage or current to the internal battery (BTA) during the charging mode of the internal battery (BTA) and receives voltage or current during the discharging mode of the internal battery (BTA), and a switching device (636) that performs switching to supply voltage or current from the second interface (610) to the second interface (634).

[0265] Meanwhile, the charging / discharging board (630) can supply a voltage of approximately 13V to the interface (652) of the main board (MD) when a second DC voltage (DC-IN) from the AC / DC converter (191) is supplied through the DC voltage input terminal (632).

[0266] Meanwhile, the charging / discharging board (630) can transmit a high-level power signal (POWER_ACD) to a switching element (653) in the main board (MD) when a second DC voltage (DC-IN) is supplied through the DC voltage input terminal (632).

[0267] Meanwhile, the main board (MD) may further include a signal receiving device (656) comprising a first diode to which a 65W_USB-C_EN signal is applied and a second diode to which a 100W_USB-C_EN signal is applied, a second switching element (658) connected to the signal receiving device (656), and a switching element (653) having one end connected between the signal receiving device (656) and the second switching element (658).

[0268] For example, when a second DC voltage (DC-IN) is supplied through the DC voltage input terminal (632), a high-level power signal (POWER_ACD) is input to the switching element (653), and the switching element (653) is turned off. Accordingly, the second switching element (658) is also turned off.

[0269] Accordingly, the 20V_VBUS_ON / OFF signal output from the second switching element (658) becomes low level, and the switching device (636) in the charge / discharge board (630) is turned off based on the low level 20V_VBUS_ON / OFF signal.

[0270] Accordingly, when the second DC voltage (DC-IN) is supplied through the DC voltage input terminal (632), the supply of the first DC voltage (Vm) or the first DC current (IPHm) to the charge / discharge board (630) is interrupted due to the off of the switching device (636).

[0271] As another example, when a second DC voltage (DC-IN) is supplied through the DC voltage input terminal (632), a low-level power signal (POWER_ACD) is input to the switching element (653), and the switching element (653) is turned on.

[0272] Meanwhile, depending on the operation of the sync mode, if either the 65W_USB-C_EN signal or the 100W_USB-C_EN signal is at a high level, the signal receiving device (656) conducts and the second switching element (658) is also turned on.

[0273] Accordingly, the 20V_VBUS_ON / OFF signal output from the second switching element (658) becomes high level, and the switching device (636) in the charge / discharge board (630) is turned on based on the high level 20V_VBUS_ON / OFF signal.

[0274] Ultimately, when the second DC voltage (DC-IN) is not supplied through the DC voltage input terminal (632), the first DC voltage (Vm) or the first DC current (IPHm) is supplied to the charge / discharge board (630) due to the turning on of the switching device (636). Accordingly, the internal battery (BTA) can be charged stably.

[0471] As shown in the drawing, when there is no image displayed on the display (180) within the image display device (100x) and there is a first touch input for a first point (PPa) of the display (180), the image display device (100x) can transmit coordinate information for the first touch input to a mobile terminal (600).

[0472] Meanwhile, the mobile terminal (600) can match coordinate information for the first touch input to the first location (PPam) within the mobile terminal (600) while displaying the image (1610).

[0473] As another example, when there is no image displayed on the display (180) within the image display device (100x), and there is a second touch input for a second point (PPb) of the display (180), the image display device (100x) can transmit coordinate information for the second touch input to the mobile terminal (600).

[0474] Meanwhile, the mobile terminal (600) can match coordinate information for the second touch input to a second location (PPbm) within the mobile terminal (600) while displaying the image (1610).

[0475] Meanwhile, as shown in FIG. 16a, if the size and resolution of the image display device (100x) and the size and resolution of the mobile terminal (600) are different, it may not be easy to match the touch input of the image display device (100x) into the mobile terminal (600), and there may be a disadvantage of lowering the accuracy.

[0478] Meanwhile, the mobile terminal (600) can match coordinate information for a drag input into the mobile terminal (600) while displaying the image (1610). In particular, it can match to a drag input from a third position (PPcm) to a fourth position (PPdm) within the mobile terminal (600).

[0479] Meanwhile, as shown in FIG. 16b, if the size and resolution of the image display device (100x) and the size and resolution of the mobile terminal (600) are different, it may not be easy to match the drag input of the image display device (100x) into the mobile terminal (600), and there may be a disadvantage of lowering the accuracy.

[0480] Furthermore, in order to match the drag input to the mobile terminal (600), there is an inconvenience of having to drag from the third point (PPc) at the left end to the third point (PPd) at the right end.

[0565] Meanwhile, in FIGS. 17a to 19b, coordinate information transmission based on touch input of the image display device (100) is exemplified, but similarly, coordinate information transmission based on an input signal from the input device (700) is also possible.

[0566] That is, when coordinate information based on input signals such as a keyboard (903), a remote control device (200), a mouse (900a), a second mouse (900b), and a game pad (904) is received, the signal processing device (170) can convert the coordinate information based on the input signals as shown in FIGS. 17a to 19b and transmit it to an external device (1200).
