Description

MOVABLE TV AND CONTROLLING METHOD OF THE MOVABLE TV}

The present invention relates to a movable TV and a control method for the movable TV.

Recently, new form factors are being discussed in multimedia devices such as mobile phones and TVs. Form factor refers to the structured form of a product.

The background to the growing importance of form factor innovation in the display industry is due to increased mobility of consumers, convergence between devices, and rapid progress in smartization, which moves away from the typical form factor tailored to specific usage environments in the past and enables User needs for form factors that can be used freely and conveniently are growing stronger.

For example, vertical TVs are expanding, breaking the stereotype of watching TV horizontally. Vertical TV is a product that allows the screen orientation to be changed, reflecting the characteristics of the MZ generation who are accustomed to enjoying content on mobile devices. You can easily view images from SNS or shopping sites, and read comments while watching a video, making it convenient. In particular, the advantages of vertical TVs shine even brighter when linked with smartphones using the near-field communication (NFC)-based mirroring function. When watching regular TV or movies, you can switch to landscape.

As another example, rollable TVs and foldable smartphones are similar in that they both use 'flexible displays'. A flexible display literally refers to a flexible electronic device. To be flexible, it must first be thin. The substrate that receives information and converts it into light must be thin and flexible to ensure long-lasting performance without damage.

Being flexible means that it should not be greatly affected by shocks. While the flexible display is bent or folded, the joints are continuously under pressure. It needs to be highly durable so that the inside is not damaged by such pressure, but it also needs to be able to deform easily when pressure is applied.

Flexible displays are implemented based on OLED, for example. OLED is a display using organic light-emitting materials. Organic materials are relatively more flexible than inorganic materials such as metals. Furthermore, OLED has a thinner substrate, making it more competitive than other displays. In the case of the LCD substrate used in the past, there is a limit to reducing the thickness because separate liquid crystal and glass are required.

As a new form factor for TVs, demand for TVs that can be easily moved indoors and outdoors is increasing. In particular, due to the recent coronavirus pandemic, users are spending more time at home, and demand for second TVs is increasing. Additionally, due to the increase in the population going outdoors for camping and other activities, there is a demand for TVs with new form factors that can be easily carried and moved.

Additionally, if you use the TV while moving it, problems with the TV not being leveled properly may occur.

In relation to this, according to a prior patent (Publication No. 10-2008-0024407), a configuration using a gyro sensor to find the location of a robot is disclosed. However, there has not yet been a proposal for an example where a gyro sensor is used for leveling in a movable TV.

The present invention aims to solve the above-mentioned problems and other problems.

Figure 1 is a block diagram for explaining each configuration of the TV 100 according to an embodiment of the present invention.

The TV 100 includes a broadcast reception unit 110, an external device interface unit 171, a network interface unit 172, a storage unit 140, a user input interface unit 173, an input unit 130, a control unit 180, It may include a display module 150, an audio output unit 160, and/or a power supply unit 190.

The broadcast reception unit 110 may include a tuner unit 111 and a demodulation unit 112.

Meanwhile, unlike the drawing, the TV 100 includes only the external device interface unit 171 and the network interface unit 172 among the broadcast receiver 110, the external device interface unit 171, and the network interface unit 172. It is also possible. That is, the TV 100 may not include the broadcast reception unit 110.

The tuner unit 111 may select a broadcast signal corresponding to a channel selected by the user or all previously stored channels among broadcast signals received through an antenna (not shown) or a cable (not shown). The tuner unit 111 can convert the selected broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

For example, if the selected broadcast signal is a digital broadcast signal, the tuner unit 111 may convert it into a digital IF signal (DIF), and if the selected broadcast signal is an analog broadcast signal, it may be converted into an analog baseband video or audio signal (CVBS/SIF). That is, the tuner unit 111 can process digital broadcasting signals or analog broadcasting signals. The analog base band video or audio signal (CVBS/SIF) output from the tuner unit 111 may be directly input to the control unit 180.

Meanwhile, the tuner unit 111 can sequentially select broadcast signals of all broadcast channels stored through a channel memory function among received broadcast signals and convert them into intermediate frequency signals or baseband video or audio signals.

Meanwhile, the tuner unit 111 may be equipped with multiple tuners in order to receive broadcast signals of multiple channels. Alternatively, a single tuner that simultaneously receives broadcast signals from multiple channels is also possible.

The demodulator 112 may receive the digital IF signal (DIF) converted by the tuner unit 111 and perform a demodulation operation. The demodulator 112 may perform demodulation and channel decoding and then output a stream signal (TS). At this time, the stream signal may be a multiplexed video signal, audio signal, or data signal.

The stream signal output from the demodulator 112 may be input to the control unit 180. After performing demultiplexing and video/audio signal processing, the control unit 180 can output video through the display module 150 and audio through the audio output unit 160.

For example, proximity sensor, illumination sensor, touch sensor, infrared sensor, ultrasonic sensor, optical sensor, e.g. , camera), a voice sensor (e.g., a microphone), a battery gauge, and an environmental sensor (e.g., a hygrometer, a thermometer, etc.).

The control unit 180 checks the status of the TV 100 based on the information collected by the sensing unit 120 and notifies the user when a problem occurs or adjusts itself to maintain the best condition.

In addition, the content, image quality, size, etc. of the image provided to the display module 180 can be controlled differently depending on the viewer or surrounding illumination detected by the sensing unit to provide an optimal viewing environment. As smart TVs advance, the number of functions mounted on the TV increases and the number of sensing units 20 also increases.

The input unit 130 may be provided on one side of the main body of the TV 100. For example, the input unit 130 may include a touch pad, physical buttons, etc. The input unit 130 can receive various user commands related to the operation of the TV 100 and transmit control signals corresponding to the input commands to the control unit 180.

Recently, as the size of the bezel of the TV 100 has become smaller, the number of TVs 100 with the physical button-shaped input unit 130 exposed to the outside has been minimized. Instead, a minimal physical button is located on the back or side, and user input can be received through the remote control device 200 through a touchpad or a user input interface unit 173, which will be described later.

The storage unit 140 may store programs for processing and controlling each signal in the control unit 180, or may store processed video, audio, or data signals. For example, the storage unit 140 stores application programs designed for the purpose of performing various tasks that can be processed by the control unit 180, and selects some of the stored application programs at the request of the control unit 180. can be provided.

Programs stored in the storage unit 140 are not particularly limited as long as they can be executed by the control unit 180. The storage unit 140 may perform a function for temporarily storing video, voice, or data signals received from an external device through the external device interface unit 171. The storage unit 140 can store information about a certain broadcast channel through a channel memory function such as a channel map.

Although FIG. 1 shows an embodiment in which the storage unit 140 is provided separately from the control unit 180, the scope of the present invention is not limited thereto, and the storage unit 140 may be included in the control unit 180.

The storage unit 140 includes volatile memory (e.g., DRAM, SRAM, SDRAM, etc.), non-volatile memory (e.g., flash memory, hard disk drive (HDD), and solid state drive (Solid- It may include at least one of state drive (SSD), etc.).

The display module 150 converts the video signal, data signal, OSD signal, and control signal processed by the control unit 180 or the video signal, data signal, and control signal received from the interface unit 171 to generate a driving signal.

The display module 150 may convert image signals, data signals, OSD signals, control signals, etc. processed by the control unit 180 to generate driving signals for a plurality of pixels.

The display module 150 can be a plasma display panel (PDP), a liquid crystal display (LCD), an organic light emitting diode (OLED), a flexible display module, etc., and can also be a three-dimensional display module (3D display). may be possible. The 3D display module 150 can be divided into a glasses-free type and a glasses type.

The TV 100 includes a display module that occupies most of the front area and a case that covers the rear side of the display module and packages the display module.

Recently, the TV 100 uses a display module 150 that can be bent, such as LED (Light Emitting Diodes) or OLED (Organic Light Emitting Diodes), to implement a curved screen beyond the flat screen. Available.

LCDs, which were mainly used in the past, received light through a backlight unit because it was difficult for the LCD to emit light on its own. The backlight unit is a device that uniformly supplies the light source and the light supplied from the light source to the liquid crystal located on the front. As the backlight unit became increasingly thinner, it was possible to implement a thin LCD, but it is difficult to implement the backlight unit using a flexible material, and when the backlight unit is bent, it is difficult to supply light uniformly to the liquid crystal, causing a problem in that the brightness of the screen changes.

On the other hand, in the case of LED or OLED, each element that makes up the pixel emits light on its own, so it can be implemented in a curved manner without using a backlight unit. In addition, since each element emits its own light, even if the positional relationship with neighboring elements changes, its own brightness is not affected, so the flexible display module 150 can be implemented using LED or OLED.

OLED (Organic Light Emitting Diode) panels appeared in earnest in the mid-2010s and are quickly replacing LCD in the small and medium-sized display market. OLED is a display made using a self-luminous phenomenon that emits light when a current flows through a fluorescent organic compound. The picture quality response speed is faster than that of LCD, so there is almost no afterimage when displaying a video.

OLED uses three types of phosphor organic compounds, including red, green, and blue, which have a self-luminous function. Electrons and positively charged particles injected from the cathode and anode are used to emit light. Since it is a light-emitting display product that utilizes the phenomenon of self-emitting light by combining within organic materials, there is no need for a backlight (halo device) that reduces color.

The LED (Light Emitting Diode) panel is a technology that uses one LED element as one pixel, and the size of the LED element can be reduced compared to the prior art, making it possible to implement a flexible display module 150. Previously, devices called LED TVs used LEDs as a light source for the backlight unit that supplied light to the LCD, but the LEDs themselves did not constitute a screen.

The display module includes a display panel, a coupling magnet located on the back of the display panel, a first power supply, and a first signal module. The display panel may include a plurality of pixels (R, G, B). A plurality of pixels (R, G, B) may be formed in each area where a plurality of data lines and a plurality of gate lines intersect. A plurality of pixels (R, G, B) may be placed or arranged in a matrix form.

For example, the plurality of pixels (R, G, B) include a red (R) subpixel, a green (Green, 'G') subpixel, and a blue (Blue, 'B') subpixel. It can be included. The plurality of pixels (R, G, B) may further include a white (hereinafter referred to as 'W') subpixel.

The side of the display module 150 that displays images may be referred to as the front or front side. When the display module 150 displays an image, the side from which the image cannot be observed may be referred to as the rear or back side.

Meanwhile, the display module 150 is composed of a touch screen and can be used as an input device in addition to an output device.

Looking at (d) of FIG. 5, the TV 100 may include a support member 500 to horizontally mount the display module 150 on the lower case. Here, the support member 500 may use the same support member 500 as in (b) of FIG. 5, but the hinge 510 included in the support member 500 is used to horizontally support the display module 150. may be in a more folded state.

Additionally, in one embodiment, the display module 150 may be manually placed horizontally or vertically by the user's hand. In another embodiment, the display module 150 may be mounted horizontally or vertically on the bottom case based on control of the TV 100. At this time, the TV 100 can mount the display module 150 horizontally or vertically based on a user's control signal (detection through a sensing unit or input unit).

Figure 6 is a diagram illustrating an example of outputting an alarm on a TV according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described content will be omitted.

Referring to FIG. 6, in one embodiment of the present invention, TV 100 can recognize users within a first range. In one embodiment, the TV 100 may output an alarm based on the recognized user's location information. At this time, the TV 100 can recognize objects within the first range. In other words, the TV 100 can recognize objects within the first range based on the TV 100, rather than limited to people. However, for convenience of explanation, recognition of people will be used as an example.

More specifically, the TV 100 can detect the location of nearby users from the location where the TV 100 is placed. At this time, the TV 100 may utilize a camera or microphone to detect the location of nearby users. Examples of this will be described in detail in FIGS. 7 and 8.

The TV 100 may output a warning or alarm based on the user's location information received through the audio output unit (not shown) of FIG. 1. At this time, the audio output unit of the TV 100 may be located in the upper case of the housing.

Additionally, the TV 100 can output a voice signal saying “Be careful of your safety as you are approaching the TV!” through the audio output unit. This is to notify the sudden approach of a user or object because the movable TV 100 including detachable legs may be located outdoors rather than indoors. For example, since the TV 100 is located outdoors, an alarm can be output by detecting an object to protect the TV 100 from flying balls or children running outside.

At this time, the TV 100 can set the alarm level differently depending on whether the leg is attached or whether it is indoors/outdoors. This will be explained in detail in FIG. 9.

Figure 7 is a diagram illustrating an example of detecting the location of a nearby user on a TV according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described content will be omitted.

Referring to FIG. 7, the TV 100 further includes a camera and can recognize the user through the camera. In one embodiment, the TV 100 may output the alarm described above in FIG. 6 when the size of the user recognized through the camera increases frame by frame.

More specifically, the TV 100 can recognize people through a camera attached to the TV 100 (for example, it may be included on a display module). At this time, the TV 100 may use a wide-angle camera to recognize a wide area.

In one embodiment, the TV 100 may determine that a person is approaching when the size of the person recognized through the camera increases frame by frame. Accordingly, the TV 100 can output an alarm when the size of the person exceeds the threshold.

Additionally, in one embodiment, the TV 100 may not output an alarm when the user's eyes detected through the camera are staring at the display module. In other words, the TV 100 can detect an arbitrary object through a camera, but when a person's eyes are detected, an alarm may not be output even if the object grows larger in units of frames. This is because, when the user approaches the TV 100 while looking at the display module, it may be determined that the purpose is to control the TV 100.

FIG. 8 is a diagram illustrating another embodiment of detecting the location of a nearby user on a TV according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described content will be omitted.

Referring to FIG. 8, the TV 100 further includes a microphone and can recognize the user through the microphone. In one embodiment, the TV 100 may output the alarm described above in FIG. 6 when the strength of the signal recognized through the microphone gradually increases.

In one embodiment, the TV 100 may detect the user's movements and sounds recognized through a microphone through high-frequency sensing technology. At this time, the TV 100 may determine that a user is approaching when the movement sound becomes louder. Accordingly, the TV 100 may output an alarm when the intensity of sound gradually received exceeds the threshold.

In one embodiment, the TV 100 may control the intensity of the alarm output depending on the distance of the approaching user. For example, when the distance between the approaching user and the TV 100 is 3 m, the TV 100 outputs an alarm at 30 dB, and when the distance between the approaching user and the TV 100 is 1 m, the alarm is output at 150 dB. Can be printed.

In addition, in combination with the embodiment of FIG. 7, the TV 100 will not output an alarm when it detects that the user's gaze is facing the display module even if the sound of the user moving closer to the TV 100 becomes louder. You can.

Figure 9 is a diagram illustrating an example of adjusting the alarm level depending on whether legs are attached in a TV according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described content will be omitted.

Referring to FIG. 9 , when the legs 220a, 220b, 220c, and 220d are attached to the lower case, the TV 100 can recognize the user within the first range as in the embodiments of FIGS. 6 to 8.

More specifically, when the legs 220a, 220b, 220c, and 220d are not attached, the TV 100 may be determined to be placed indoors or in use in a safe state.

On the other hand, in one embodiment, when the legs 220a, 220b, 220c, and 220d are attached, the TV 100 may be determined to be used outdoors or in an unsafe condition. Accordingly, when the legs 220a, 220b, 220c, and 220d are attached, the TV 100 can detect that an object is approaching within the first range. The TV 100 may output an alarm when an object is detected within the first range while the legs 220a, 220b, 220c, and 220d are attached.

That is, the TV 100 can use whether the legs 220a, 220b, 220c, and 220d are attached as an alarm trigger.

On the other hand, in another embodiment, the TV 100 outputs an alarm at the first intensity when the legs 220a, 220b, 220c, and 220d are attached, and when the legs 220a, 220b, 220c, and 220d are not attached, the TV 100 outputs an alarm at the first intensity. The alarm can be output in the second century. At this time, the first century is characterized as being larger than the second century.

That is, the TV 100 can output an alarm when an object is detected regardless of whether the legs 220a, 220b, 220c, and 220d are attached. On the other hand, the TV 100 can control the intensity of the output alarm based on whether the legs 220a, 220b, 220c, and 220d are attached.

More specifically, when the legs 220a, 220b, 220c, and 220d are attached to the TV 100, it may be determined that the TV 100 is being used outdoors or in an unsafe condition. Accordingly, when the legs 220a, 220b, 220c, and 220d are attached, the TV 100 may output an alarm at the first intensity when an object is detected in the first range. On the other hand, when the legs 220a, 220b, 220c, and 220d of the TV 100 are not attached, it may be determined that the TV 100 is being used indoors or in a safe state. Accordingly, when the legs 220a, 220b, 220c, and 220d are not attached, the TV 100 may output an alarm at the second intensity when an object is detected in the first range. At this time, the first century is characterized as being larger than the second century.

That is, the TV 100 can output a louder alarm sound when the legs 220a, 220b, 220c, and 220d are attached.

10 and 11 are diagrams illustrating an example of leveling a TV based on a gyro sensor according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described content will be omitted.

Referring to FIG. 10 , the TV 100 may further include a horizontal sensor including a gyro sensor and an acceleration sensor. Here, since the gyro sensor can know the rotation angle and tilt of a rotating object, it can be used together with an acceleration sensor to measure the acceleration of the object or the strength of the impact to effectively recognize motion.

Referring to the left drawing of FIG. 10, the TV 100 uses an acceleration sensor to measure acceleration in the x-axis, y-axis, and z-axis, and uses a gyro sensor to perform roll rotation about the x-axis. Pitch rotation about the y-axis and yaw rotation about the z-axis can be measured. Accordingly, the TV 100 can accurately determine whether the TV 100 is horizontal.

In one embodiment, the TV 100 can be leveled using a level sensor.

More specifically, the TV 100 may further include a first motor that controls whether the display module 150 is horizontal. Here, the first motor is included in the upper case or lower case and is connected to the display module 150 to control whether the display module 150 is horizontal. Accordingly, the TV 100 can measure the level of the display module 150 using a horizontal sensor and adjust the level of the display module 150 using the first motor.

In another embodiment, TV 100 may include a second motor that controls the length of the leg. Here, the second motor may be included in the bottom case to which the leg is attached to control the length of the leg. As described above, the TV 100 can determine whether the display module 150 is horizontal using a horizontal sensor. The TV 100 can adjust the length of the legs using the second motor based on the determined level of horizontality.

In one embodiment, if the degree of tilt of the TV 100 for more than a first time (eg, 10 seconds) is greater than or equal to a first value (eg, plus or minus 3 degrees relative to the horizontal) through the horizontal sensor, Leveling can be achieved using at least one of the first motor and the second motor.

More specifically, the user controlling the TV 100 can change the tilt of the TV 100 by temporarily touching the TV 100. However, until this case, it is unnecessary to control the first motor or the second motor to level the TV 100. Accordingly, the TV 100 can be leveled only when the degree of tilt for more than the first time is greater than or equal to the first value.

In addition, when the TV 100 is outdoors, it may be difficult to achieve perfect levelness because the road surface may be uneven. Accordingly, the TV 100 can be leveled when the TV 100 is not perfectly horizontal but has a degree of inclination greater than or equal to the first value.

In another embodiment, the TV 100 may further include a position detection unit that detects the position of the TV 100. Here, the location detection unit can determine the current location of the TV 100 by using a GPS module or the like or by collecting information received from the broadcast receiver, sensing unit, input unit, and interface unit described above in FIG. 1.

The TV 100 may vary the horizontal standard that the TV 100 must control in consideration of the current location of the TV 100.

More specifically, when the location of the TV 100 is outdoors, the TV 100 uses the horizontal standard of the TV 100 as the first reference, and when the location of the TV 100 is indoors, the TV 100 uses the horizontal standard of the TV 100 as the first reference. The horizontal standard of can be used as the second standard. Here, the range of the first standard is characterized as being larger than the range of the second standard.

As described above, when the TV 100 is installed outdoors, it may be difficult to perfectly level the TV 100 because the road surface is uneven. To compensate for this, when the TV 100 is outdoors, the horizontal range can be slightly relaxed so that the first standard for leveling the TV 100 can be set a little wider. On the other hand, when the TV 100 is installed indoors, the horizontal range can be narrower than the first standard.

As such, the TV 100 according to an embodiment of the present invention is movable and can be installed outside, so it is important to keep it level. To this end, the TV 100 can be leveled using at least one of the first motor and the second motor.

At this time, as described above with reference to FIG. 10 , the TV 100 adjusting the level of the display module 150 using at least one of the first motor or the second motor may be referred to as an automatic mode.

On the other hand, a user using the TV 100 can manually control the level of the TV 100. This will be explained in detail in FIG. 11.

Referring to FIG. 11 , the TV 100 may output status information 1100 of the TV 100 detected through the horizontal sensor through the display module 150.

In one embodiment, the TV 100 may display at least one of the position and degree of the leg 220d that needs to be adjusted to level the TV 100.

More specifically, the TV 100 can measure the horizontality of the TV 100 through the above-described method. Afterwards, the TV 100 may output status information 1100 of the TV 100 including the measured degree of horizontality through the display module 150. Here, the status information 1100 may indicate the degree of tilt of the TV 100 in terms of appearance.

The TV 100 may display at least one of the position, degree, and length of the leg 220d that needs to be adjusted to level the TV 100. Referring to the example of FIG. 11, the TV 100 may display that the leg 220d should be lowered by 3 cm.

FIG. 11 includes an example in which the TV 100 provides guidance through the display module 150 so that the user can directly adjust the length of the legs 220a, 220b, 220c, and 220d. However, it goes without saying that the embodiment of FIG. 10 can be applied to other contents. For example, in the embodiment of FIG. 11 , the TV 100 determines whether the status information 1100 should be output to the display module 150 based on whether the current location of the TV 100 is outdoors or indoors. can be decided.

Additionally, in one embodiment, when the user begins to control the length of the legs, the TV 100 may detect the level of the TV 100 and apply it to the status information 1100 to output new information.

Through this, the movable TV 100 can easily compensate for the degree of inclination of the TV 100.

FIG. 12 is a diagram illustrating an example of protecting a display module when a horizontal sensor of a TV changes suddenly according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described content will be omitted.

Referring to FIG. 12, when the horizontal change of the TV 100 detected through the horizontal sensor exceeds a threshold, the TV 100 may close the upper case of the housing to protect the display module 150.

Additionally, the TV 100 may control the display module 150 to be stored in the lower case when the horizontal change of the TV 100 detected through the horizontal sensor exceeds a threshold value.

Here, the threshold value may be determined based on location information of the TV 100. That is, as described above, since the movable TV 100 can be located indoors or outdoors, the threshold value can be set differently based on the location where the TV 100 is currently located.

More specifically, when the TV 100 is located outdoors, when the horizontal change of the TV 100 exceeds the first threshold, the TV 100 closes the upper case of the housing or closes the display module 150. It can be controlled to be stored in this lower case.

On the other hand, when the TV 100 is located indoors and the horizontal change of the TV 100 exceeds the second threshold, the TV 100 closes the upper case of the housing or the display module 150 closes the lower case. It can be controlled to be stored in . Here, the second threshold may be smaller than the first threshold.

That is, when the TV 100 is outdoors, the horizontal change may be greater than indoors depending on road surface information or environmental information. Considering this, the TV 100 operates to protect the display module 150 even in a narrower range of horizontal changes when indoors, and protects the display module 150 from a wider range of horizontal changes when outdoors. It can operate to protect.

Accordingly, when the TV 100 detects a sudden horizontal change, the display module 150 can be stored inside the housing or bottom case to protect the display module 150.

13 and 14 are flowcharts explaining a method of controlling a TV according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described content will be omitted.

Referring to FIG. 13, in step S1310, the TV can recognize an object within the first range. In one embodiment, a TV can recognize an object through a camera. At this time, the TV may output an alarm in step S1330 or step S1340 when the size of the object recognized through the camera increases frame by frame.

In one embodiment, the TV can detect the user's eyes when the recognized object is the user. At this time, the TV may not output an alarm when the detected user's eyes are staring at the display module.

In another embodiment, the TV can recognize an object through a microphone. At this time, the TV may output an alarm in step S1330 or step S1340 when the strength of the signal recognized through the microphone gradually increases.

In step S1320, the TV can determine whether the leg is attached to the housing.

In one embodiment, the TV may recognize an object within the first range when the leg is attached to the bottom case of the housing.

When the leg is attached to the housing, in step S1330, the TV may output a first intensity alarm based on the location information of the recognized object.

If the leg is not attached to the housing, in step S1340, the TV may output a second intensity alarm based on the location information of the recognized object. At this time, the first century is characterized as being larger than the second century.

Referring to FIG. 14, in step S1410, the TV may operate in an automatic mode based on whether the TV is level detected through a level sensor. Here, the horizontal sensor may include a gyro sensor and an acceleration sensor. The TV can be leveled based on whether the TV is level detected through a level sensor.

In step S1420, the TV can control the horizontality of the display module using the first motor. To this end, the first motor may be attached to the display module to control the horizontality of the display module.

In step S1430, the TV can adjust the length of the leg using the second motor. For this purpose, a second motor may be attached to the leg to control the length of the leg.

In step S1440, the TV may operate in a manual mode based on whether the TV is level detected through a level sensor.

In step S1450, the TV may output the horizontal state of the TV through the display module.

In step S1460, the TV may display at least one of the position, degree, and length of the leg that needs to be adjusted to level the TV.
