Additionally, the control unit outputs the user interface until the pivot angle of the head satisfies the first angle and the tilt angle of the head satisfies the second angle.

Additionally, the first angle is 0 degrees, and the second angle is 0 degrees.

Additionally, at least one of the first angle and the second angle is determined by user settings.

Additionally, the control unit is characterized in that it outputs an alarm when the pivot angle of the head satisfies the first angle or the tilt angle of the head satisfies the second angle.

The demodulator 1212 may receive the digital IF signal (DIF) converted by the tuner unit 1211 and perform a demodulation operation. The demodulator 1212 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 1212 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.

The control unit 180 can check the status of the display device 100 based on the information collected by the sensing unit 120 and notify the user when a problem occurs or control it to maintain the best condition by adjusting it on its own.

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 display devices 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 display device 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 display device 100 and transmit control signals corresponding to the input commands to the control unit 180.

Recently, as the size of the bezel of the display device 100 has become smaller, the number of display devices 100 in which the input unit 130 in the form of a physical button exposed to the outside has been minimized has increased. 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.

12 shows an embodiment in which the storage unit 140 is provided separately from the control unit 180, but 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. You can. The display module 150 may include a display panel 181 having a plurality of pixels.

A plurality of pixels provided in the display panel may include RGB subpixels. Alternatively, a plurality of pixels provided in the display panel may include RGBW subpixels. 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 display device 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 display device 100 is 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 a flat surface. can be used.

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.

In addition, the functions performed by each block are for explaining embodiments of the present invention, and the specific operations or devices do not limit the scope of the present invention.

In using the above-described display device, there was difficulty in accurate alignment because the head was operated in landscape or portrait mode, and only visual judgment was made during manual operation without compensation for horizontal and vertical errors. In addition, there was a problem that automatic operation depended only on motor drive.

To solve this problem, in one embodiment of the present invention, a 6-axis gyro sensor detects at least one of the pivot angle and tilt angle of the head, and performs horizontal and vertical correction on the display panel based on the detected pivot angle and tilt angle. We want to provide functionality.

In one embodiment of the present invention, the display device 100 may output user interfaces 1301, 1302, and 1303 on the display panel 150 based on the pivot angle of the head.

More specifically, the display device 100 may include a sensor that detects the pivot angle and tilt angle of the head, although not shown in the drawing. Here, the sensor is a 6-axis gyro sensor that can detect the pivot angle and tilt angle of the head when the display device 100 operates in landscape mode or portrait mode.

In one embodiment, the display device 100 may change the shape of the icon based on the pivot angle of the head.

For example, when the pivot angle of the head is tilted 10 degrees to the left, the display device 100 may output the first user interface 1301 as shown in (a) of FIG. 13A.

On the other hand, when the pivot angle of the head is tilted by 5 degrees to the left, the display device 100 may output the second user interface 1302 as shown in (b) of FIG. 13A.

Finally, when the pivot angle of the head is 0 degrees (horizontal), the display device 100 may output the third user interface 1303 as shown in (c) of FIG. 13A.

In one embodiment of the present invention, the display device 100 may terminate the output of the user interfaces 1301, 1302, and 1303 when a first time elapses after outputting the user interfaces 1301, 1302, and 1303. there is. For example, when the pivot angle of the head is tilted 10 degrees to the left, the display device 100 outputs the first user interface 1301 as shown in (a) of FIG. 13A, and after 3 seconds, the first user interface 1301 ) can be terminated.

In one embodiment of the present invention, the display device 100 may output user interfaces 1301, 1302, and 1303 when head movement is detected. That is, the display device 100 may output user interfaces 1301, 1302, and 1303 when the user manually moves the head or the head is automatically moved by a motor.

Additionally, although not shown in the drawing, the display device 100 may output a user interface that guides the user to satisfy the first angle set by the user. Additionally, the display device 100 may output an alarm when the first angle set by the user is satisfied. This will be explained in detail in Figure 15.

In particular, the embodiments of FIGS. 13A and 13B are described by taking the case where the display device 100 is in landscape mode as an example, but it can of course also be applied when the display device 100 is in portrait mode.

FIGS. 14A and 14B are diagrams illustrating an example of outputting a user interface based on a head tilt angle detected by a display device according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described drawings will be omitted.

In one embodiment of the present invention, the display device 100 may

output user interfaces

1401, 1402, and 1403 on the display panel 150 based on the tilt angle of the head. As described above, the display device 100 may include a sensor for detecting the tilt angle of the head.

14A and 14B, the display device 100 may

output user interfaces

1401, 1402, and 1403 on the display panel 150 based on the detected tilt angle of the head. Here, the

user interfaces

1401, 1402, and 1403 may include at least one of an icon and text. At this time, the text may represent text indicating an angle. For example, text could indicate “-10 degrees,” “-5 degrees,” “0 degrees,” “It’s level,” or “OK.” Additionally, the icon may indicate the degree to which the display panel 150 is tilted.

In one embodiment of the present invention, the display device 100 may change the shape of the icon based on the tilt angle of the head.

For example, when the tilt angle of the head is tilted forward by 10 degrees, the display device 100 may output the first user interface 1401 as shown in (a) of FIG. 14A.

On the other hand, when the tilt angle of the head is tilted forward by 5 degrees, the display device 100 may output the second user interface 1402 as shown in (b) of FIG. 14A.

Finally, when the tilt angle of the head is 0 degrees (vertical), the display device 100 may output the third user interface 1403 as shown in (c) of FIG. 14A.

In one embodiment of the present invention, the display device 100 may terminate the output of the

user interfaces

1401, 1402, and 1403 when a first time elapses after outputting the

user interfaces

1401, 1402, and 1403. there is. For example, when the tilt angle of the head is tilted forward by 10 degrees, the display device 100 outputs the first user interface 1401 as shown in (a) of FIG. 14A, and after 3 seconds, the first user interface 1401 ) can be terminated.

In one embodiment of the present invention, the display device 100 may

output user interfaces

1401, 1402, and 1403 when head movement is detected. That is, the display device 100 may output the

user interfaces

1401, 1402, and 1403 when the user manually moves the head or the head is automatically moved by a motor. At this time, the

user interfaces

1401, 1402, and 1403 output may indicate the tilt angle of the head.

In particular, the embodiments of FIGS. 14A and 14B are described by taking the case where the display device 100 is in portrait mode as an example, but it can of course also be applied when the display device 100 is in landscape mode.

13A to 14B, in one embodiment of the present invention, the display device 100 outputs a user interface (not shown) until the pivot angle of the head or the tilt angle of the head satisfies the first angle 1501. can do. At this time, the first angle 1501 may be determined by user settings.

More specifically, in the case of the display device 100 including a head that can be changed to landscape mode or portrait mode, there are cases where the user uses the display device 100 while standing in the kitchen or lying on the bed instead of using it fixedly. There may be.

In this case, since it is not used fixedly like a regular TV, the user needs to change the pivot angle or tilt angle of the display device 100 to suit the user's convenience.

For example, a user who uses the display device 100 while lying on his right side in bed may be more comfortable with the head pivot angle tilted 20 degrees to the right than when it is horizontal. In this case, the user can set the first angle 1501 to a pivot angle tilted 20 degrees to the right.

Additionally, as another example, a user who uses the display device 100 while lying on a sofa may find it more comfortable when the head is tilted forward by 20 degrees than when the head is tilted vertically. In this case, the user can set the first angle 1501 to a tilt angle tilted forward by 20 degrees. (see Figure 15)

Accordingly, the display device 100 may output the user interface until the first angle 1501 set by the user is satisfied. Here, the user interface may include an icon and text indicating the current head pivot angle or the current head field angle.

13A to 15 illustrate an embodiment of separately outputting a user interface indicating the pivot angle of the head and a user interface indicating the tilt angle of the head. However, the display device 100 displays the head on the display panel 150. Of course, it is possible to output a first user interface indicating the pivot angle and a second user interface indicating the tilt angle of the head.

Figure 16 is a flowchart explaining a display control method according to an embodiment of the present invention. Hereinafter, descriptions that overlap with the above-described drawings will be omitted.

In step S1610, the display device has a display panel, includes a head capable of pivoting and tilting, and can detect the pivot angle and tilt angle of the head.

In step S1620, the display device may output a user interface on the display panel based on at least one of the detected pivot angle and tilt angle of the head. In one embodiment of the present invention, the display device may simultaneously output a first user interface based on the pivot angle of the head and a second user interface based on the tilt angle of the head on the display panel. Here, the first user interface may include an icon and text indicating the current pivot angle of the head. Additionally, the second user interface may include an icon and text indicating the current head tilt angle.

In one embodiment of the present invention, when movement of the head is detected in step S1610, the display device may output a user interface. More specifically, the display device can move the head automatically by a motor or manually by the user, and can output a user interface when head movement is detected.

In one embodiment of the present invention, the display device may end output of the user interface after the first time period has elapsed. More specifically, the display device displays the user interface when a first period of time (e.g., 3 seconds, 5 seconds, etc. can be set by the manufacturer or the user) elapses after the user interface is output according to the movement of the head. Printing can be terminated.

In one embodiment of the present invention, the display device may output a user interface until the pivot angle of the head satisfies the first angle and the tilt angle of the head satisfies the second angle. Here, the first angle and the second angle may correspond to 0 degrees by default. However, in another embodiment, the user may individually set the first angle and the second angle.

In one embodiment of the present invention, the display device may output an alarm when the pivot angle of the head satisfies the first angle or the tilt angle of the head satisfies the second angle.

Additionally, in FIGS. 13A to 15 , the description is focused on an embodiment in which the head of the display device pivots and tilts, but an embodiment of the present invention can be applied to pivot, tilt, swivel, and elevating operations of the head.
