Description

Technical Field

[0001] The present invention relates to a mobile TV and a control method of the mobile TV. Background Art

[0002] Recently, new form factors are being discussed in multimedia devices such as mobile phones and TVs. Form factor refers to the structural form of a product.

[0003] In the display industry, the important background of form factor innovation is the increase in consumer mobility, the integration of devices and the acceleration of intelligentization. Therefore, users have an increasingly strong demand for form factors that can be used freely and conveniently without being restricted by the conditions of the usage environment, rather than the typical form factors that were customized for specific usage environments in the past.

[0004] For example, vertical TVs are increasing in popularity, breaking the stereotype of watching TV in horizontal orientation. Vertical TVs are products that can switch screen orientation, reflecting the characteristics of the MZ generation who are used to watching content on their mobile phones. It is convenient to watch images on SNS or shopping websites, and it is convenient to read reviews while watching videos. In particular, the advantages of vertical TVs are more obvious when linked to smartphones using the mirroring function based on near-field wireless communication (NFC). You can switch to horizontal orientation when watching regular TV or movies.

[0005] As another example, the similarity between roll-up TVs and foldable smartphones is that they both use "flexible displays." As the name suggests, flexible displays refer to soft electronic devices. In order to be flexible, they must first be thin. The substrate that receives information and converts it into light must be thin and flexible to maintain performance for a long time without being damaged.

[0006] Softness means that even if it is impacted, it will not be greatly affected. During the bending or folding of the flexible display, the joints are constantly under pressure. In order to prevent the inside from being damaged under such pressure, it is necessary to have excellent durability and a property that can deform freely when pressure is applied.

[0007] For example, flexible displays are realized based on OLED. OLED is a display that uses organic light-emitting substances. Organic substances are relatively soft compared to inorganic substances such as metals. Furthermore, the thickness of the OLED substrate is thin, so it is more competitive than other displays. In the case of the LCD substrate used in the past, separate liquid crystals and glass are required, so there are limitations in reducing the thickness.

[0008] Finally, as a new form factor for TV, the demand for TVs that can be easily moved indoors and outdoors is increasing. In particular, due to the recent spread of the new coronavirus, users are spending more time at home, and the demand for a second TV is also increasing. In addition, the actual situation is that due to the increase in the number of people going out for fun such as camping, a new form factor TV that can be easily carried and moved is needed.

[0049] Figure 1This is a block diagram for explaining each component of a TV (television set) 100 according to an embodiment of the present invention.

[0050] The TV 100 may include a broadcast receiving 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 , a display module 150 , an audio output unit 160 and / or a power supply unit 190 .

[0051] The broadcast receiving section 110 may include a tuner 111 and a demodulator 112 .

[0052] On the other hand, unlike the figure, the TV 100 may include only the external device interface 171 and the network interface 172 among the broadcast receiving unit 110, the external device interface 171 and the network interface 172. That is, the TV 100 may not include the broadcast receiving unit 110.

[0053] The tuner 111 may select a broadcast signal corresponding to a channel selected by a user or all pre-stored channels from broadcast signals received through an antenna (not shown) or a cable (not shown). The tuner 111 may convert the selected broadcast signal into an intermediate frequency signal or a baseband image or voice signal.

[0054] For example, if the selected broadcast signal is a digital broadcast signal, the tuner 111 may convert it into a digital IF (DIF: Digital Intermediate Frequency) signal, and if the selected broadcast signal is an analog broadcast signal, the tuner 111 may convert it into an analog baseband image or voice signal (CVBS / SIF). That is, the tuner 111 may process a digital broadcast signal or an analog broadcast signal. The analog baseband image or voice signal (CVBS / SIF) output from the tuner 111 may be directly input to the control unit 180.

[0055] On the other hand, the tuner 111 may sequentially select broadcast signals of all broadcast channels stored by the channel memory function from among the received broadcast signals and convert them into intermediate frequency signals or baseband image or voice signals.

[0056] On the other hand, in order to receive broadcast signals of a plurality of channels, the tuner 111 may include a plurality of tuners, or may be a single tuner that simultaneously receives broadcast signals of a plurality of channels.

[0057] The demodulation unit 112 may receive the digital IF signal (DIF) converted by the tuner 111 and perform a demodulation operation. The demodulation unit 112 may output a stream signal (TS) after performing demodulation and channel decoding. At this time, the stream signal may be a signal multiplexed with an image signal, a voice signal, or a data signal.

[0058] The stream signal output from the demodulation part 112 may be input to the control part 180. The control part 180 may output an image through the display module 150 and output a voice through the audio output part 160 after performing demultiplexing, image / voice signal processing, and the like.

[0059] The sensing unit 120 refers to a device that senses changes in the TV 100 or senses changes outside the TV 100. For example, it may include at least one of a proximity sensor, an illumination sensor, a touch sensor, an infrared sensor (IR sensor: infrared sensor), an ultrasonic sensor, an optical sensor (optical sensor, such as a camera), a voice sensor (such as a microphone), a battery gauge, and an environmental sensor (such as a hygrometer, a thermometer, etc.).

[0060] The control unit 180 may control the TV 100 to check the state of the TV 100 based on the information collected from the sensing unit 120 , and to notify the user of a problem when it occurs, or to maintain an optimal state through self-adjustment.

[0061] In addition, the content, quality, size, etc. of the image provided to the display module 180 are controlled differently according to the viewer or the surrounding illumination sensed by the sensing unit, so that the best viewing environment can be provided. With the advancement of smart TVs, the functions installed in the TVs have increased, and the sensing unit 20 has also increased accordingly.

[0062] The input unit 130 may be provided at one side of the body of the TV 100. For example, the input unit 130 may include a touch pad, a physical button, etc. The input unit 130 may receive various user commands related to the operation of the TV 100, and may transmit a control signal corresponding to the input command to the control unit 180.

[0063] Recently, as the frame size of TV 100 becomes smaller, more and more TV 100 has an input unit 130 in the form of a physical button exposed to the outside in a minimized form at the frame. Instead, a minimum of physical buttons are set on the back or side, and the user's input through the remote control device 200 can be received through a touch panel or a user input interface unit 173 described later.

[0064] The storage unit 140 may store programs for processing and controlling various signals in the control unit 180, and may also store signal-processed image, voice, or data signals. For example, the storage unit 140 may store application programs designed for executing various tasks that can be processed by the control unit 180, and may selectively provide a portion of the stored plurality of application programs upon request from the control unit 180.

[0065] The program or the like stored in the storage unit 140 is not particularly limited as long as it can be executed by the control unit 180. The storage unit 140 may also perform a function for temporarily storing an image, voice, or data signal received from an external device through the external device interface unit 171. The storage unit 140 may store information on a predetermined broadcast channel through a channel memory function such as a channel map.

[0066] Figure 1 Although the embodiment in which the storage unit 140 and the control unit 180 are separately provided is shown, the scope of the present invention is not limited thereto, and the storage unit 140 may be included in the control unit 180 .

[0067] The storage unit 140 may include at least one of a volatile memory (eg, DRAM, SRAM, SDRAM, etc.), a non-volatile memory (eg, a flash memory, a hard disk drive (HDD), a solid-state drive (SSD), etc.).

[0068] The display module 150 may convert image signals, data signals, OSD signals, control signals, etc. processed in the control part 180 or received from the interface part 171 and generate driving signals. The display module 150 may include a display panel 181 having a plurality of pixels.

[0069] The plurality of pixels provided in the display panel may have RGB (red, green, and blue) sub-pixels. Alternatively, the plurality of pixels provided in the display panel may also have RGBW (red, green, blue, and white) sub-pixels. The display module 150 may convert the image signal, data signal, OSD signal, control signal, etc. processed in the control unit 180, and generate a driving signal for the plurality of pixels.

[0070] The display module 150 may be a PDP (Plasma Display Panel), LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode), a flexible display module, etc. In addition, it may be a 3D display module. The 3D display module 150 may be divided into a non-glasses type and a glasses type.

[0071] The TV 100 includes a display module occupying most of the area of ​​the front side and a case covering the back side, side sides, etc. of the display module and packaging the display module.

[0072] Recently, in order to realize a curved screen from a flat screen, the TV 100 may use a bendable display module 150 such as LED (Light Emitting Diodes) or OLED (Organic Light Emitting Diodes).

[0073] The LCD mainly used in the prior art is difficult to emit light by itself, so it receives light through a backlight unit. The backlight unit is a device that evenly supplies a light source and light supplied from the light source to a liquid crystal disposed on the front. The backlight unit is gradually becoming thinner, so that a thin LCD can be realized, but it is difficult to realize the backlight unit with a curved material, and in the case of a curved backlight unit, there is a problem that the brightness of the screen changes due to difficulty in supplying uniform light to the liquid crystal.

[0074] On the other hand, in the case of LED or OLED, since each element constituting a pixel emits light by itself, a backlight unit is not used, and thus bending can be achieved. In addition, each element emits light by itself, so even if the positional relationship between adjacent elements changes, its own brightness is not affected, so a curved display module 150 can be achieved using LED or OLED.

[0075] OLED (Organic Light Emitting Diodes) panels officially appeared in mid-2010 and quickly replaced LCD in the small and medium-sized display market. OLED is a display made by using the self-luminescence phenomenon that emits light when electric current flows through fluorescent organic compounds. Compared with LCD, the image quality response speed is faster, so there is almost no afterimage when realizing moving images.

[0076] OLED is a light-emitting display product that uses three types of red, green, and blue fluorescent organic compounds with self-luminous functions, and utilizes the phenomenon that electrons injected from the cathode and anode combine with positively charged particles in the organic matter to emit light by themselves. Therefore, there is no need to use a backlight (backlight device) that reduces color perception.

[0077] LED (Light Emitting Diode) panel is a technology that uses one LED element as one pixel, and can reduce the size of the LED element compared to the prior art, thereby enabling a curved display module 150. In the past, a device called LED TV used LED as a light source of a backlight unit that supplies light to an LCD, but LED itself cannot form a screen.

[0078] The display module includes a display panel, a combined magnet located on the back of the display panel, a first power supply unit and a first signal module. The display panel may include a plurality of pixels (R, G, B). The 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. The plurality of pixels (R, G, B) may be configured or arranged in a matrix shape.

[0079] For example, a plurality of pixels (R, G, B) may include a red (Red, hereinafter "R") sub-pixel, a green (Green, "G") sub-pixel, and a blue (Blue, "B") sub-pixel. A plurality of pixels (R, G, B) may also include a white (White, hereinafter "W") sub-pixel.

[0080] The side of the display module 150 where the image is displayed may be referred to as the front side or the front side. The side where the image cannot be observed when the display module 150 displays the image may be referred to as the rear side or the back side.

[0081] On the other hand, the display module 150 is constituted by a touch screen, and can be used as an input device in addition to an output device.

[0082] The audio output unit 160 receives the voice-processed signal from the control unit 180 and outputs it in the form of voice.

[0083] The interface part 170 performs a channel role with various types of external devices connected to the TV 100. The interface part may include a wired method of transmitting and receiving data through a cable and a wireless method using an antenna.

[0084] The interface portion 170 may include at least one of a wireless / headphone port, an external charger port, a wireless / data port, a memory card port, a port for connecting a device with an identification module, an audio I / O (Input / Output) port, a video I / O (Input / Output) port, and a headphone port.

[0085] As an example of a wireless method, the aforementioned broadcast receiving unit 110 may be included, and broadcast signals as well as mobile communication signals, short-range communication signals, wireless Internet signals, and the like may be included.

[0086] The external device interface unit 171 can transmit and receive data with an external device connected thereto. To this end, the external device interface unit 171 may include an A / V input and output unit (not shown).

[0087] The external device interface unit 171 can be connected to external devices such as DVD (Digital Versatile Disk), Blu-ray, game equipment, camera, camcorder, computer (laptop), set-top box, etc. in a wireless or wireless manner, and can also perform input / output operations with the external devices.

[0088] Furthermore, the external device interface unit 171 establishes a communication network with various remote control devices 200 , thereby being able to receive control signals related to the operation of the TV 100 from the remote control device 200 or transmit data related to the operation of the TV 100 to the remote control device 200 .

[0089] The external device interface unit 171 may include a wireless communication unit (not shown) for short-range wireless communication with other electronic devices. Through such a wireless communication unit (not shown), the external device interface unit 171 can exchange data with an adjacent mobile terminal. In particular, the external device interface unit 171 can receive device information, executed application information, application images, etc. from the mobile terminal in the mirroring mode.

[0090] The network interface unit 172 may provide an interface for connecting the TV 100 to a wired / wireless network including the Internet. For example, the network interface unit 172 may receive content or data provided by the Internet or a content provider or a network operator through a network. On the other hand, the network interface unit 172 may include a communication module (not shown) for connecting to a wired / wireless network.

[0091] The external device interface unit 171 and / or the network interface unit 172 may include communication modules for short-range communication such as Wi-Fi (Wireless Fidelity), Bluetooth, Bluetooth Low Energy (BLE), Zigbee, NFC (Near Field Communication), and communication modules for cellular communication such as LTE (long-term evolution), LTE-A (LTE Advance), CDMA (code division multiple access), WCDMA (wideband CDMA), UMTS (universal mobile telecommunications system), and WiBro (Wireless Broadband).

[0092] The user input interface unit 173 may transmit a signal input by the user to the control unit 180 or transmit a signal from the control unit 180 to the user. For example, the user input signal such as power on / off, channel selection, screen setting, etc. may be transmitted to the remote control device 200 or received from the remote control device 200, or a user input signal input from a local key (not shown) such as a power key, a channel key, a volume key, and a setting key may be transmitted to the control unit 180, or a user input signal input from a sensor unit (not shown) for sensing a user's gesture may be transmitted to the control unit 180 or a signal from the control unit 180 may be transmitted to the sensor unit.

[0093] The control unit 180 may include at least one processor, and the processor included therein may be used to control the overall operation of the TV 100. Here, the processor may be a common processor such as a CPU (central processing unit). Of course, the processor may be a dedicated device such as an ASIC or other hardware-based processor.

[0094] The control section 180 may demultiplex a stream input through the tuner section 111 , the demodulator section 112 , the external device interface section 171 , or the network interface section 172 , or may process the demultiplexed signal to generate and output a signal for image or voice output.

[0095] The image signal processed by the control unit 180 may be input to the display module 150 and displayed as an image corresponding to the image signal. In addition, the image signal processed by the control unit 180 may be input to an external output device through the external device interface unit 171.

[0096] The voice signal processed in the control section 180 may be outputted as sound to the audio output section 160. In addition, the voice signal processed in the control section 180 may be inputted to an external output device through the external device interface section 171. In addition, the control section 180 may include a demultiplexing section, an image processing section, and the like.

[0097] In addition, the control unit 180 may control the overall operation of the TV 100. For example, the control unit 180 may control the tuner 111 to select (Tuning) a broadcast corresponding to a channel selected by a user or a pre-stored channel.

[0098] In addition, the control unit 180 may control the TV 100 using a user command or an internal program input through the user input interface unit 173. On the other hand, the control unit 180 may control the display module 150 to display an image. At this time, the image displayed in the display module 150 may be a still image or a moving image, and may be a two-dimensional (2D) image or a three-dimensional (3D) image.

[0099] On the other hand, the control unit 180 can display a predetermined 2D object in the image displayed on the display module 150. For example, the object can be at least one of a connected web page screen (newspaper, magazine, etc.), EPG (Electronic Program Guide), various menus, small windows, icons, still images, moving images, and text.

[0100] On the other hand, the control unit 180 can modulate and / or demodulate the signal using an amplitude shift keying (ASK) method. Here, the amplitude shift keying (ASK) method may refer to a method of modulating a signal by distinguishing the amplitude of a carrier according to a data value, or a method of restoring an analog signal to a digital data value according to the amplitude of a carrier.

[0101] For example, the control unit 180 may modulate the image signal using an amplitude shift keying (ASK) method and transmit the image signal through the wireless communication module.

[0102] For example, the control unit 180 may demodulate and process the image signal received through the wireless communication module using an amplitude shift keying (ASK) method.

[0103] Thus, the TV 100 can easily transmit and receive signals with other image display devices arranged adjacently, without using a unique identifier such as a MAC address (Media Access Control Address) or a complicated communication protocol such as TCP / IP.

[0104] On the other hand, TV100 may further include a shooting unit (not shown). The shooting unit may shoot a user. The shooting unit may be implemented by one camera, but is not limited thereto, and may also be implemented by a plurality of cameras. On the other hand, the shooting unit may be embedded in the TV100 on the upper part of the display module 150 or configured separately. The image information captured by the shooting unit may be input to the control unit 180.

[0105] The control unit 180 can identify the user's position based on the image captured by the camera unit. For example, the control unit 180 can grasp the distance (Z-axis coordinate) between the user and the TV 100. In addition, the control unit 180 can grasp the X-axis coordinate and Y-axis coordinate corresponding to the user's position in the display module 150.

[0106] The control unit 180 may sense the user's gesture based on one or a combination of the image captured by the capturing unit and the signal sensed by the sensor unit.

[0107] The power supply unit 190 can supply corresponding power to the entire TV 100. In particular, it can supply power to the control unit 180 which can be implemented in the form of a system on chip (SOC), the display module 150 for displaying images, and the audio output unit 160 for audio output.

[0108] Specifically, the power supply unit 190 may include a converter (not shown) for converting AC power into DC power and a DC / Dc converter (not shown) for converting the level of the DC power.

[0109] On the other hand, the power supply unit 190 receives power from the outside and distributes it to each component. The power supply unit 190 may include a power supply unit 190 that can directly connect to an external power source and supply AC power, or a power supply unit 190 that can include a battery and charge it for use.

[0110] In the former case, the connection uses a wired cable, which makes it difficult to move or the range of movement is limited.

Here, the handle 300 may have a structure attached to the left and right sides of the upper housing or the lower housing so that the user can carry the cover body closed by the upper housing and the lower housing. In this case, the handle 300 may be made of a material such as leather or plastic that is easy for the user to lift with his hands.

[0124] That is, the TV 100 includes the handle 300 , and a user can easily carry and move the TV 100 in a state where the upper housing or the lower housing is closed.

[0125] In addition, if necessary, the user can place the lower housing on the floor and open the upper housing to use the mounted display module 150. Figure 4 and Figure 5 Detailed description is given in .

[0126] In addition, in one embodiment, the TV 100 may further include a storage space 310 located on the side of the lower housing. Here, the storage space 310 may include Figure 2 In addition, the storage space 310 may include a space capable of storing a touch-pen or a wireless earphone.

[0127] Figure 41 is another diagram showing an application example of a TV according to an embodiment of the present invention.

[0128] In one embodiment of the present invention, the TV 100 may include four legs. In this case, the four legs are attached to the lower end housing, and the TV 100 can be separated from the floor.

[0129] Thereby, the user can use the TV 100 not only while moving but also in a fixed position separated from the floor.

[0130] Figure 4 (a) to (d) show an application example in which the legs of TV 100 are attached and used in a fixed position. Figure 4 (a) shows a state where the upper housing of TV100 is closed. Figure 4 (b) to (d) show the state in which the upper end shell is opened.

[0131] Specifically, Figure 4 (b) shows a state where the display module 150 is stored in the lower housing when the upper housing is open. Figure 4 (b) shows a state where the display module 150 is placed flat in the lower housing when the upper housing is opened. When the display module 150 is stored in the lower housing, the display module 150 can also be activated.

[0132] In one embodiment, the TV 100 may provide an editing mode when the display module 150 is stored in the lower housing. Here, the editing mode may include adding at least one of a memo function, a drawing function, and a voice recording function to the content.

[0133] That is, when the display module 150 is placed on the lower housing, the TV 100 may determine that the user wants to enjoy / watch content through the display module 150 .

[0134] On the other hand, when the display module 150 is stored in the lower housing, the TV 100 may determine that the user wants to edit the content output to the display module 150. Thus, when the display module 150 is stored in the lower housing, the TV 100 may provide a function of editing the content.

[0135] Figure 4 (c) indicates that the display module 150 is placed horizontally on the lower housing when the upper housing is opened. Figure 4 (d) indicates that the display module 150 is placed vertically in the lower housing when the upper housing is opened. Figure 4 (c) and (d) show a state where the display module 150 stands upright with the lower end housing as a foothold.

[0136] In addition, in one embodiment, the TV 100 may use a motor (not shown) to automatically store or place the display module 150 in the lower housing.

[0137] In more detail, if the upper housing is opened, the TV 100 may automatically place the display module 150 on the lower housing in a horizontal or vertical direction.

[0138] In addition, in another embodiment, if the upper housing of TV100 is open, the display module 150 may be first stored in the lower housing. Then, TV100 may place the display module 150 on the lower housing based on a signal of touching the display module 150 or a signal input from a sensing unit or an input unit. For example, a user may place the display module 150 on the lower housing by pressing down on the display module 150 stored inside the lower housing. Figure 5 Detailed description is given in .

[0139] Figure 5 The front and side views of a TV according to an embodiment of the present invention are shown in FIG.

[0140] Figure 5 (a) and Figure 5 (b) shows the state where the display module 150 is placed vertically. Figure 5 (c) and Figure 5 (d) indicates a state where the display module 150 is placed horizontally.

[0141] Figure 5 (a) and Figure 5 (c) is a diagram showing TV 100 from the front. Figure 5 (b) and Figure 5 (d) is a diagram showing the TV 100 from the side.

[0142] In one embodiment, the upper housing may include an audio output portion 160, so Figure 5 In (a), the display module 150 may be placed vertically, and there may be an upper housing including an audio output unit 160 at the rear end.

[0143] observe Figure 5 (b), in order to place the display module 150 longitudinally on the lower housing, the TV 100 may further include a supporting member 500. Figure 5 As shown in (b), if the TV 100 is viewed from the side, the support member 500 may be included in the lower housing and is designed to be folded so as to vertically place the display module 150. At this time, the support member 500 may be controlled by the motor of the TV 100 or manually operated by the user.

[0146] In addition, in one embodiment, the display module 150 can be manually placed horizontally or vertically by the user's hand. In another embodiment, the display module 150 can be placed horizontally or vertically on the lower end housing based on the control of the TV 100. At this time, the TV 100 can place the display module 150 horizontally or vertically based on the user's control signal (sensed by the sensing unit or the input unit).

[0147] Figure 6 This is a diagram for explaining a TV model according to an embodiment of the present invention. Hereinafter, descriptions overlapping with the above contents will be omitted.

[0148] In one embodiment of the present invention, the TV 100 can sense the opening action of the lower shell of the cover. That is, the user can switch to the upper shell of the TV 100 by opening the upper shell of the TV 100. Figure 6 (a) status or Figure 6 (b) status.

[0149] Thus, the TV 100 can determine the current position of the TV. At this time, in order to determine the current position of the TV 100, the TV 100 can use various sensors. Figure 8 Detailed description is given in .

[0150] TV 100 can determine whether the current position is the same as the position just before it was turned off.

[0151] In one embodiment, when the current position is the same as the position just before being turned off, the TV 100 may operate in the mode just before being turned off. At this time, the mode may include a first mode, a second mode, and a third mode.

[0152] Figure 6 (a) illustrates the first mode and the third mode, Figure 6 (b) of the present invention describes the second mode. In this case, the first mode and the third mode may refer to the speaker mode, and the second mode may refer to the video mode. Figure 7a and Figure 7bLet me explain again.

[0153] In more detail, the first mode and the third mode indicate modes in which the display module 150 remains coupled to the cover, and the second mode indicates a mode in which the display module 150 is in an upright state in the cover.

[0154] At this time, the first mode and the third mode are different in that the current position and time of the TV 100 differ from the previous use by more than a specified time. That is, the TV 100 can operate in the third mode instead of the first mode. At this time, the third mode can correspond to a mode in which a connectable external device is connected based on a user selection.

[0155] More specifically, when at least one of the position and time immediately before the power-off differs from at least one of the current position and the current time by more than a predetermined position and a predetermined time, the TV 100 may be operated in the third mode.

[0156] At this time, the TV 100 may switch to a connection waiting mode for an external device without connecting to an external device with a previous connection history (which will be Figure 7a Thus, in the third mode, the TV 100 can wait for a control signal from the user without being connected to an external device. Afterwards, when the user connects an external device to the TV 100, the TV 100 can perform subsequent actions.

[0157] In addition, in one embodiment, the TV 100 can output content based on the current location and the current time in the third mode. Fig. 9 Detailed description in.

[0158] That is, Figure 4 and Figure 5 As described above, TV 100 can store or place display module 150 in the cover of TV 100 in various ways. The present invention proposes a method for determining in which mode TV 100 is used and what content is output on display module 150 by considering various environmental information such as the current position and current time of TV 100 when the upper end of the cover is opened.

[0159] Figure 7a and Figure 7b FIG. 1 is a diagram for explaining an embodiment of a TV-based mode connection device according to an embodiment of the present invention.

[0160] In one embodiment of the present invention, Figure 7a is a diagram illustrating the first mode, Figure 7b 2 is a diagram illustrating the second mode. As described above, Figure 7a The first mode may represent the speaker mode, Figure 7b The second mode may represent a video mode.

[0161] Reference Figure 7a , in the case of executing the mode just before shutdown, the TV 100 may automatically connect to the external device 700 that was last connected to the TV 100. Here, the external device 700 may include a smartphone, a tablet PC, a notebook computer, and the like.

[0162] In more detail, when the upper end shell of the cover of TV100 is opened, and the current position of TV100 is the same as the position just before shutting down, TV100 can execute the first mode. Here, the first mode is the speaker mode, and TV100 can be controlled to keep the display module 150 combined with the cover.

[0163] In one embodiment, the TV 100 may be directly connected to the external device 700 that was previously connected via Bluetooth connection, etc. At this time, the TV 100 may use the communication module that was previously connected to the external device 700.

[0164] In one embodiment, when the TV 100 is operated in the first mode, the audio output unit attached to the upper housing of the cover can output the sound signal of the external device 700. At this time, the TV 100 outputs the sound signal received from the external device 700 and outputs the sound-specific theme screen 710 such as a record on the display module 150.

[0165] on the other hand, Figure 7b This shows an embodiment in which the TV 100 operates in the video mode as the second mode. Figure 7b The user can open the upper shell of TV100 to make the display module 150 stand up from the lower shell of the cover and keep it in the standing state.

[0166] In addition, you can use Figure 7a Related embodiments. In more detail, the user can use the TV 100 in the first mode and attach the display module 150 to the lower end shell of the cover body for use, and then separate the display module 150 from the lower end shell and change it to an upright state. Thus, the TV 100 can operate in the second mode. That is, the user's action of separating the display module 150 from the lower end shell can be a trigger for the second mode.

[0167] In one embodiment, the TV 100 may output a content selection screen 720 on the display module 150 when operating in the second mode.

[0168] In more detail, the TV 100 may terminate the output of the sound signal being output (or being played) during operation in the first mode. Then, the TV 100 may output a content selection screen 720 for video viewing through the display module 150. Here, the content selection screen 720 may correspond to the initial screen of the ordinary TV 100.

[0169] That is, even if one embodiment of the present invention is a mobile TV 100, in addition to the embodiment used in the speaker mode, it can operate like a normal TV 100 when used in the video mode. To this end, the TV 100 can output the content selection screen 720 on the display module 150 and receive a control signal from the user when operating in the second mode.

[0170] Then, the TV 100 can output various contents received from the broadcast receiving unit based on a control signal of a remote control device (not shown).

[0171] Figure 8 1 is a diagram for explaining an embodiment of sensing the position movement of a TV according to an embodiment of the present invention.

[0172] In one embodiment, the TV 100 may determine the current location and the current time of the TV 100 by various means.

[0173] For more details, refer to Figure 8 As the upper shell of the cover body is opened, TV100 can determine at least one of the current location and the current time.

[0174] To this end, in one embodiment, the TV 100 may further include a microphone. The TV 100 may determine the current position of the TV 100 based on noise information received through the microphone. Here, the information may include a noise pattern.

[0175] In one embodiment, the TV 100 may collect first noise information received through a microphone at a time point when the upper end shell of the cover is opened. The TV 100 may determine the current position of the TV 100 by comparing an existing noise pattern with a noise pattern included in the first noise information.

[0176] For example, when TV100 is used indoors, the noise pattern may be constant. On the other hand, when TV100 is located outdoors on a certain day, the noise information received by the microphone at the time when the upper end housing of TV100 is opened may be different from the noise pattern indoors. Thus, TV100 can determine whether the current location is indoors or outdoors, etc.

[0177] In another embodiment, the TV 100 may further include an illumination sensor. The TV 100 may determine the current position of the TV 100 based on the amount of light sensed by the illumination sensor. That is, the amount of light collected by the illumination sensor may be different in indoor and outdoor situations. Thus, the TV 100 may determine whether the current position of the TV 100 is indoors or outdoors through the illumination sensor.

[0178] In addition, in another embodiment, TV100 can Figure 1 The network interface unit described in receives the position information of the TV 100. Thus, the TV 100 can determine the current position based on the received position information.

[0179] In addition, TV100 can integrate Figure 8 The method described in the above can more accurately determine the location information of TV100. For example, when TV100 determines that the current location is outdoor, it can be known that the current location is Han River Park based on the information received through the network interface unit, etc. Thus, TV100 can compare the determined current location with the previous location and select to execute the first mode or the third mode.

[0180] Fig. 9 This is a diagram for explaining an embodiment of outputting an image based on TV status information according to an embodiment of the present invention. Hereinafter, descriptions overlapping with the above contents will be omitted.

[0181] Fig. 9 An embodiment applicable when the display module 150 is attached to the lower end housing of the cover body as in the first mode and the third mode described above is described in detail.

[0182] That is, when the position just before shutdown and the current position are the same as in the first mode, and when the position just before shutdown and the current position are different as in the third mode, TV 100 can output content matching the theme through the display module 150.

[0183] In one embodiment, the network interface part of the TV 100 may be connected to a server, and the TV 100 may receive image information about the current location of the TV 100 from the server. The TV 100 may output the image information through the display module 150. At this time, the TV 100 may receive the image information based on the current time.

[0184] For more details, refer to Fig. 9(a), when it is determined that the current position is outdoor and the current time is night, the TV 100 can output a campfire theme through the display module 150. In one embodiment, the TV 100 can transmit the information that the current position is outdoor and the current time is night to the server, and receive image information corresponding to the campfire theme from the server based on the information that the current position is outdoor and the current time is night. At this time, the server can retrieve the image theme based on the current position and the current time and transmit it to the TV 100.

[0185] In addition, refer to Fig. 9 (b), when it is determined that the current position is indoors and the current time is daytime, the TV 100 may output a window theme of direct sunlight through the display module 150. The TV 100 may transmit the information that the current position is indoors and the current time is daytime to the server, and receive image information corresponding to the window theme of direct sunlight from the server based on the information that the current position is indoors and the current time is daytime.

[0186] Fig.10 1 is a flowchart for explaining a TV control method according to an embodiment of the present invention.

[0187] Reference Fig.10 In step S1010, the TV may sense the opening action of the upper shell of the cover body.

[0188] In step S1020, the TV may determine the current location of the TV.

[0189] In step S1030, the TV may determine whether the current position is the same as the position just before it was turned off. In one embodiment, the TV may determine the current position of the TV based on the noise information received through the microphone. Here, the noise information may include a noise pattern. In more detail, the TV collects the noise information received through the microphone at the time when the upper end shell of the cover is opened, and determines the current position of the TV by comparing the existing noise pattern with the noise pattern included in the collected noise information. To this end, the TV may store the existing noise pattern in a memory.

[0190] In one embodiment, the TV may determine the current position of the TV based on the amount of light sensed by the illumination sensor. In another embodiment, the TV may receive the current position information of the TV through the network interface unit and determine the current position of the TV based on the received position information.

[0191] In step S1040, when the current position is the same as the position just before being powered off, the TV may operate in the mode just before being powered off. Here, the mode just before being powered off may include a first mode and a second mode. In one embodiment, when the mode just before being powered off is executed, the TV may automatically connect to the external device that was last connected to the TV.

[0192] In step S1050, the TV may operate in a first mode. Here, the first mode refers to a mode in which the display module of the TV remains in a state of being combined with the cover. In one embodiment, when the TV operates in the first mode, the TV may output a sound signal of an external device through an audio output portion of an upper housing attached to the cover.

[0193] In step S1060, the TV may operate in the second mode. Here, the second mode refers to a mode in which the display module of the TV is in an upright state in the cover. In one embodiment, when the TV operates in the second mode, the TV may output a content screen on the display module.

[0194] In step S1070, when the current position is different from the position just before the power is turned off, the TV can operate in the third mode. Here, the third mode means a mode for connecting other connectable external devices based on user selection. In one embodiment, the TV determines the time just before the TV is turned off, and when the current time in step S1010 is different from the time just before the power is turned off, the TV can operate in the third mode. That is, when at least one of the current position and time is different from at least one of the position and time just before the power is turned off, the TV can operate in the third mode.

[0195] In addition, of course, Figures 6 to 9 The embodiments described in Fig.10 Execute in that way.

[0196] The above detailed description should not be interpreted as limiting in all aspects, but should be considered as illustrative.
