The broadcast receiver 110 may include a tuner 111 and a demodulator 112 .

On the other hand, the smart media system 100, unlike the figure, only the external device interface unit 171 and the network interface unit 172 among the broadcast receiving unit 110 , the external device interface unit 171 , and the network interface unit 172 . It is also possible to include That is, the smart media system 100 may not include the broadcast receiver 110 .

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

Recently, the display module 150 is a flexible display module 150 such as LED (Light Emitting Diodes) or OLED (Organic Light Emitting Diodes, organic light emitting diodes) to implement a curved screen further than a flat surface. is available.

In the conventional LCD, it was difficult for the LCD to emit light by itself, so light was supplied through the backlight unit. The backlight unit is a device that uniformly supplies the light source and the light supplied from the light source to the liquid crystal positioned in front. As the backlight unit became thinner, a thin LCD could be realized. However, it is difficult to implement the backlight unit with a flexible material, and when the backlight unit is curved, it is difficult to supply uniform light to the liquid crystal, so there is a problem that the brightness of the screen changes.

On the other hand, in the case of LED or OLED, since each element constituting a pixel emits light by itself, it can be implemented to be curved without using a backlight unit. In addition, since each element emits light by itself, it does not affect its own brightness even if a positional relationship with a neighboring element is changed. Therefore, a flexible display module 150 can be implemented using an LED or OLED.

OLED (Organic Light Emitting Diodes) panels appeared in earnest in mid-2010 and are rapidly replacing LCDs in the small and medium-sized display market. OLED is a display made by using the self-luminescence phenomenon that emits light when an electric current flows through a fluorescent organic compound. The image quality response speed is faster than that of LCD, so there is almost no afterimage when implementing a video.

OLED uses three types of phosphor organic compounds with self-luminous function: red, green, and blue. Electrons and positively charged particles injected from the cathode and anode are As it is a light-emitting display product that uses the phenomenon of emitting light by combining within an organic material, there is no need for a backlight (backlight device) that reduces color.

The LED (Light Emitting Diode, 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, so that the flexible display module 150 can be implemented. Conventionally, a device called LED TV uses LED as a light source for a backlight unit that supplies light to LCD, but the LED itself did not constitute a screen.

The display module includes a display panel, a coupling magnet positioned on the rear surface 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, and B. The plurality of pixels R, G, and B may be formed in each region where the plurality of data lines and the plurality of gate lines intersect.

Meanwhile, the controller 180 may control the display 150 to display an image. In this case, the image displayed on the display 150 may be a still image or a moving image, and may be a 2D image or a 3D image.

2 is a perspective view illustrating an example of the smart media system 100 of the present invention, and FIG. 3 is an exploded perspective view of the smart media system 100 of the present invention viewed from the front.

The smart media system 100 of the present invention includes a door assembly 200 that can be easily installed on a wall and can cover the display module 150 when not in use.

In the smart media system 100 of the present invention, a frame 211 may be installed on an indoor wall, and media products such as a display module 150 and an audio output unit 160 may be installed on the frame 211 .

In addition, unlike the screen type, it is possible to implement an interior such as a wall or furniture by using a material having a rigidity.

Hereinafter, for convenience of explanation, the horizontal direction of the smart media system 100 refers to the x-axis direction in the drawing, the vertical direction refers to the y-axis direction, and the thickness direction refers to the z-axis direction.

4 is a view for explaining the operation of the door assembly 200 of the smart media system 100 of the present invention. The door assembly 200 of the present invention is characterized in that the arrangement of the three door panels 220 is changed and the size of the display module 150 exposed to the front is changed.

FIG. 4A is a view illustrating a state (line view) when only the upper part of the display module is opened, and shows a closed state in which three door panels 220 are arranged side by side in the vertical direction.

In case of live view mode, time, temperature, humidity, and important notices can be printed and used by using the partially exposed screen at the top. The door panel 220 may be provided to cover the entire display unit instead of the line view, and in this case, the number or size of the door panel 220 may vary.

FIG. 4B is a diagram illustrating a state (half view) when only half of the display module 150 is opened. The third door panel 223 and the second door panel 222 positioned below partially overlap and expose half of the display area. In this case, the overlapping amount of the second door panel 222 and the third door panel 223 may vary according to the size of the display area exposed.

4( c ) shows that the door panel 220 may be switched to an open state for a full view mode in which the display module 150 is fully opened. In the open state, the three door panels 220 are disposed to overlap in the thickness direction under the display module 150 .

The first door panel 221 located at the top is located on the frontmost side, and the third door panel 223 located at the bottom is moved in the rear direction, so that the second door panel 222 and the first door panel 221 are located. It provides space for this to be located.

5 is an exploded perspective view viewed from the rear of the smart media system 100 , and a driving unit for driving the first to third door panels 223 , the display module 150 , and the door panel 220 is shown.

The driving unit of the present invention moves the first driving unit 240 for moving the first door panel 221 and the second door panel 222 in the vertical direction and the third door panel 223 in the thickness direction to move the second door panel (222) It may include a second driving unit 250 that provides a space for the first door panel 221 to be located.

Referring to FIG. 10 , the first driving unit 240 drives the first door panel 221 by receiving the force of the first actuator 241 having a length variable in the vertical direction and the first actuator 241 . It may include a second moving part 240b for driving the part 240a and the second door panel 222 .

The first driving unit 240 is directly coupled to the first actuator 241, but the second driving unit 250 is not directly coupled to the first actuator 241, and the first moving unit 240a and the second moving unit ( 240b), the force may be indirectly transmitted through the elastic part 243 positioned between them.

Referring to FIG. 14 , the second driving unit 250 includes a second actuator 253 having a variable length in the horizontal direction, and converts the horizontal force of the second actuator 253 in the thickness direction to the third in the thickness direction. The door panel 223 may move.

6 is a flowchart illustrating a driving sequence when the door assembly 200 of the present invention is switched from a closed state to an open state, and FIG. 7 is a driving method when the door assembly 200 of the present invention is switched from a closed state to an open state. is a diagram showing

Referring to FIG. 6 , when a signal for turning on the display module 150 is input, the first driving unit 240 and the second driving unit 250 may be activated to move the door panel 220 . A signal for turning on the display module 150 may be driven using a remote control device such as a remote control.

Upon receiving a signal to turn on the TV (S110), the control unit determines whether the door panel 220 is in an open state or a closed state. The open state refers to a state in which the door panels 220 are overlapped in the thickness direction as shown in FIG. it means.

If the door is in an open state, the TV may be turned on without the need to drive a separate door panel 220 . If the door is not in an open state, first, the second driving unit 250 is activated to start the reverse operation of the third door panel 223 (S130, #1). When the movement distance of the third door panel 220 moves by the first distance (S140, #2), the first driving unit 240 is activated to perform the lowering operation of the first door panel 221 and the second door panel 222 . Start (S150).

It stops in the same state as #3 of FIG. 7 using only the half-view screen as shown in FIG. 4(b). The third door panel 223, which is switched from the line view to the half view, stops moving at the first distance and waits, and only the first driving unit 240 is further lowered to the first door panel 221 and the second door panel 222. When the screen size of the display module 150 corresponding to the half view is secured by moving , the first driving unit 240 may also stop the operation.

In order to switch to the full view mode, the second driving unit 250 does not stop and continues to move the third door panel 223 backward, and the second door panel 222 descends side by side with the first door panel 221 . When the third door panel 223 has been moved to the rear and moved by the second distance, and the second door panel 222 is moved to a lower portion by a predetermined distance, as shown in #4 of FIG. 7 , the second door panel 222 is moves backward than the first door panel 221 . The third door panel 223 moves rearward to secure a space for the second door panel 222 to move, and the second door panel 222 moves rearward so that the first door panel 221 is shown in FIG. 7 . As shown in #5, it can be moved to overlap the front surface of the second door panel 222 .

When the fully opened state is reached as in #5, it is determined that the designated section has been reached (S160), and the control unit operates the sensor for detecting the positions of the first driving unit 240, the second driving unit 250, and the door panel 220. may be stopped to end the driving of the door assembly 200 .

Referring to the table of FIG. 7 , the first distance traveled by the third door is 22.5 mm, and the second distance is 45 mm. 22.5 mm corresponds to the thickness of one door panel 220 and may include a gap so that the door panel 220 can move without touching it.

The moving distance of the first driving unit 240 during vertical movement may vary depending on the height of the door panel 220 . When the door panel 220 having a height of 275.5 mm is used, 551 mm can be moved. #1 in FIG. 7 shows that the first driving unit 240 is in the most tensioned state, so it is in a tensioned state by 551 mm, and after the third door panel 223 moves rearward (#2), the length is contracted and when the open state is reached, the minimum compressed to length.

The first door panel 221 and the second door panel 222 move up and down together according to the operation of the first driving unit 240, and when the second door panel 222 touches the floor, the second door panel 222 When can no longer move downward, the length of the elastic part 243 positioned between the first moving part 240a and the second moving part 240b is compressed, and the first door panel 221 and The second door panels 222 may overlap each other.

When the first door panel 221 and the second door panel 222 are arranged side by side in the vertical direction, the elastic part 243 has a maximum length and does not extend beyond that, and the first door panel 221 and the second door panel 222 have a maximum length. 222 is maximally compressed in a state in which it is overlapped and the length may be shortened.

8 is a flowchart illustrating a driving sequence of the door assembly 200 of the present invention, and FIG. 9 is a diagram illustrating a driving method when the door assembly 200 of the present invention is switched from an open state to a closed state. Although the operation is entirely opposite to the above-described operation, there is a difference in the timing of starting the operation of the second driving unit 250 in part.

When a signal to turn off the TV is detected, the display is turned off (S210, S220), and the driving unit starts to operate. Since the first door panel 221 , the second door panel 222 , and the third door panel 223 are overlapped, the first door panel 221 needs to move upward. Accordingly, the first driving unit 240 is activated and the first door panel 221 starts to move upward (S230).

When the first door moves a third distance (S240), as shown in #2 of FIG. 9 , the second door may also move in the same plane as the first door. When a moving space is secured in the front of the third door, the second driving unit 250 operates so that the third door moves to the front, and the third door panel 223 moves forward (S250).

In order to stop at the half view as in #3, the first driving unit 240 may move by a length corresponding to the half view, and the second driving unit 250 may move by the first moving distance and end the movement.

In order to switch the display module 150 to the line view state, that is, to the closed state of the door assembly 200 , the first driving unit 240 continues to move the first door panel 221 and the second door panel 222 upward. When the length of the first driving unit 240 reaches the maximum length as shown in #4, the driving of the first driving unit 240 is stopped and the second driving unit 250 starts driving again, and as shown in #5, the third door panel ( 223 is arranged side by side with the second door panel 222 .

When the second driving unit 250 also reaches the designated section, the operation of the second driving unit 250 may be stopped and the operation of the sensor for detecting the position may also be stopped.

Hereinafter, the detailed configuration and operation of each driving unit will be described in more detail so that the door panel 220 can move in the above-described order.

10 to 13 are views illustrating the first driving unit 240 . 10 is a view showing a state in which the first actuator 241 is separated, and FIG. 11 is an exploded perspective view. 12 is an enlarged view of the second moving unit 240b, and FIG. 13 is an exploded perspective view of the second moving unit 240b.

10 and 11 , the first driving unit 240 may include an actuator whose length is variable in the vertical direction. Since the length change is relatively large compared to that of the second driving unit 250 , as shown in FIG. 10 , the first actuator 241 may use a multi-stage actuator whose length varies in multiple stages. The lower end of the first actuator 241 is fixed to the lower frame 211, and the upper end of the first actuator 241 may have a vertically variable position according to the driving of the actuator.

The first moving unit 240a is responsible for moving the first door panel 221 , the second moving unit 240b is responsible for moving the second door panel 222 , and the first moving unit 240a is The first actuator 241 is directly connected and the second moving part 240b is connected to the first moving part 240a and the elastic part 243 through the elastic part 243 to indirectly receive the force of the first actuator 241 .

Accordingly, the first door panel 221 moves according to the change in length of the first actuator 241 and the second door panel 222 moves according to the change in length of the first actuator 241. First door panel At the time of overlapping with 221 , the first actuator 241 moves at a different speed from the length change speed of the first actuator 241 through the length change of the elastic part 243 .

The first moving part 240a includes a first door bracket 242 connecting the first actuator 241 and the first door panel 221 . The first door bracket supports the weight of the first door panel 221 and moves up and down according to the driving of the first actuator 241 . However, the first actuator 241 may vibrate because only the lower part is fixed and the upper part is not fixed.

For stable driving of the first door panel 221 , the first door bracket may be configured to move along a guide rail positioned on the frame 211 having a fixed structure. The first guide rail 244 fixed to the frame 211 may include a plurality of lengthwise extensions in the vertical direction as shown in FIG. 11 for stable driving.

The first door bracket coupled to the first guide rail 244 has limited movement in the horizontal direction and can move along the first guide rail 244 in the vertical direction, so that the first door panel 221 can stably move vertically. can

In order to transmit the force of the first actuator 241 to the second moving part 240b, an elastic part 243 extending downward from the first door bracket may be included. The elastic part 243 is a member that is compressed when a force is applied without extending more than the maximum length, and a gas spring may be used as a representative example.

The gas spring 243 supports the load of the second door panel 222 in a maximum tension state when the first door panel 221 and the second door panel 222 are vertically arranged, and acts as a first actuator. It is possible to transmit a force to move in response to the change in length of (241).

Since the second door panel 222 cannot move any more when the second door panel 222 is in contact with the floor, the gas spring 243 is compressed and the first door panel 221 is placed on the front surface of the second door panel 222. ) can be located.

12 and 13 , the second moving part 240b responsible for moving the second door panel 222 includes the first bracket 246 and the second door panel 222 coupled to the first guide rail 244 . ) and may include a second bracket 248 combined. Since the second door panel 222 moves in the vertical direction and then has to move in the rear direction to provide a space in which the first door panel 221 can be located at the bottom, the second moving unit 240b uses the two brackets. may include

The first bracket 246 is coupled to the first guide rail 244 to move only vertically, and the second bracket 248 is coupled to the second guide rail 245 to move in the rear direction from the bottom of the smart media system 100 . ) can be followed.

As shown in FIGS. 12 and 13 , the second guide rail 245 includes an upper rail extending in a vertical direction, an inclined rail extending from the lower end of the upper rail in the rear direction, and extending from the inclined rail in a vertical direction. Including a lower rail extending to.

That is, when the second moving part 240b is positioned at the lower part by a predetermined distance or less, the first bracket 246 and the second door panel 222 can move in the rear direction along the inclined rail.

Since the first guide rail 244 moves in the vertical direction, a linear guide including a long bar-shaped rail and a rail block moving thereon can be used, and the second guide rail 245 includes a section where it is bent. As shown in Fig. 13, it is possible to implement a long-extended groove-shaped rail.

A guide pin 249 moving along the second guide rail 245 is coupled to the second bracket 248 , and in this embodiment, the first bracket is between the second bracket 248 and the second guide rail 245 . Since the 246 is positioned, the guide pin 249 may pass through the first bracket 246 to be coupled to the second guide rail 245 . The first bracket 246 may include a hole extending in the thickness direction so that the guide pin 249 can move in the thickness direction.

The first bracket 246 and the second bracket 248 move together in the vertical direction, but when the second bracket 248 moves in the thickness direction, the first bracket 246 does not move. Therefore, the first bracket 246 and the second bracket 248 may be coupled through the third guide rail 247 extending in the thickness direction. Since the third guide rail 247 also guides only linear motion, it can be implemented in the form of a linear guide like the first guide rail 244 .

According to such a configuration in which the second moving part 240b can move in two directions, the second door panel 222 can move in the rear direction as shown in #3 to #4 in FIG. 7 , and in #1 to #2 in FIG. You can move forward together.

In order to control the driving of the first driving unit 240, a sensor for sensing the position of the first panel or sensing the length of the first actuator 241 may be further included, and based on the position or length detected by the sensor, the first Driving timings of the driving unit 240 and the second driving unit 250 may be determined.

A moving plate is needed to convert the force moving in the horizontal direction to the thickness direction. When the actuator is directly arranged in the vertical direction, there is a space limitation and there is more space in the horizontal direction, so when the horizontal movement distance is converted to the thickness direction movement distance, the ratio is small to configure the movement of the third door panel 223 can be adjusted more precisely.

The moving plate 257 is coupled to the moving plate 255 and includes a light shackle 2571 , and the second door bracket 259 is coupled to the third door panel 223 and includes a light shackle of the moving plate 257 ( 2571) through a slot pin 2591 can be coupled.

The horizontal movement of the second door bracket 259 may be restricted so that the second door panel 222 moves in the thickness direction and does not move in the horizontal direction. The slot pin 2591 of the second door bracket 259 moves along the light chain slot 2571 when the moving plate 255 moves in the horizontal direction, and the second door bracket 259 moves in the thickness direction.

The state shown in (c) is when the first door panel 221, the second door panel 222, and the third door panel 223 overlap ( open state), and corresponds to the state #5 in FIG. 7 .

A distance sensor 254 may be included to detect the position of the third door panel 223 . The distance sensor may detect a distance between the third door panel 223 and the base 251 to control driving of the second actuator 253 .

The length of the second actuator 253 is variable, and when the length is increased from x1 to x2, the moving plate 255 moves to the right in the drawing, and the second door bracket 259 moves along the inclination of the moving plate. The third door panel 223 moves in the rear direction. That is, the distance of the third door panel 223 to the base 251 also changes from y1 to y2.

When the length of the second actuator 253 becomes longer from x2 to x3, the moving plate 255 moves further to the right and the third door panel 223 moves further to the rear side, so that the second door panel 222 moves to the second side. 3 A space that can be positioned in front of the door panel 223 is provided.

y2-y1 is the aforementioned first distance, y3-y1 corresponds to the aforementioned second distance, and the ratio of the length change of the second actuator 253 to the movement distance of the third door panel 223 is the light chain chain 2571 ) can be adjusted through the slope of the
