Similarly, when a control signal for rotating the display 120 in the second posture to the first posture is received from the processor 140, the controller (not shown) controls the display 120 until 8000 pulses are counted. A pulse signal for rotating in the second direction may be sequentially output to the motor 130 . In this case, when the motor 130 rotates 40 times, the gear 30 rotates 90 degrees in the second direction, and accordingly, the display 110 coupled to the gear 30 rotates 90 degrees to become the first posture. there is.

In addition, when a control signal for rotating the display 120 to the third posture is received from the processor 140 , the controller (not shown) displays the display until a pulse for rotating the display 120 in the third posture is counted. A pulse signal for rotating 120 in the first or second direction may be sequentially output to the motor 130 . In this case, the display 110 coupled to the gear 30 may be in the third posture according to the rotation of the motor 130 .

Through the above-described method, the display apparatus 100 of the present disclosure may change the posture of the display 120 while sequentially displaying a plurality of image contents.

For example, referring to FIG. 4 , the processor 140 may receive the first image content 410 , the second image content 420 , and the third image content 430 from the server. In addition, the processor 140 receives schedule information from the server, where the schedule information includes time information for display of the first image content 410 , time information for display of the second image content 420 , and the third Time information for displaying the image content 430 may be included. In addition, the schedule information includes posture information of the display corresponding to the first image content 410 , posture information of the display on the second image content 420 , and posture information (or rotation angle) of the display on the third image content 430 . information) may be included.

For example, the display order according to the time information included in the schedule information is the order of the first image content 410 , the second image content 420 , and the third image content 430 , and the first image content included in the schedule information The posture of the display corresponding to 410 is the first posture, the posture of the display corresponding to the second image content 420 is the second posture, and the posture of the display corresponding to the third image content 430 is the third posture. In the case of the posture, as shown in FIG. 4 , the processor 140 displays the first image content 410 through the display 120 in the first posture, and then rotates the display 120 to the second posture. The second image content 420 is displayed through the display 120 in the second posture, and then the display 120 is rotated to the third posture to display the third image content 430 through the display 120 in the third posture. can do.

As described above, the display apparatus 100 of the present disclosure displays the image content in a display posture in which the user can easily recognize the content of the image content according to the schedule information, thereby providing the image content (or information related to the image content) to the user. can be provided efficiently.

As described above, the processor 140 may rotate the display 120 according to the schedule information and display the image content through the rotated display 120 .

For example, the processor 140 displays the first image content through the display 120 of the first posture, and when the display of the first image content is completed, rotates the display 120 of the first posture to the second posture After that, the second image content may be displayed through the display 120 in the second posture.

Meanwhile, as an example of displaying the image content after the rotation is completed, the processor 140 may display the image content while the display 120 is rotated.

To this end, the processor 140 may receive (or obtain) information about the rotation angle of the display 120 from a controller (not shown) while the display 120 is rotated.

Specifically, the controller (not shown) may determine the rotation angle of the display 120 based on the number of pulse signals output to the motor 130 .

For example, as in the above-described embodiment, when the motor 130 rotates by 1.8 degrees to one pulse signal and the rotation ratio of the motor 130 and the gear 30 is 160:1, the controller (not shown) When one pulse signal is output, the display 120 may be rotated by 0.01125 degrees. In this case, the controller (not shown) calculates an angle obtained by calculating 0.01125 degrees, which is the rotation angle of the display 120 rotated by the motor 130 per 1 pulse, on the number of pulse signals output to the motor 130 . ) can be determined by the rotation angle.

In addition, the controller (not shown) may obtain information on the rotation angle of the display 120 based on the calculation of the initial angle of the display 120 and the rotation angle of the display 120 .

Here, the initial angle of the display 120 may be preset based on the posture of the display 120 . As an example, the initial angle when the display 120 is in the first posture (eg, landscape posture) is preset to 0 degrees, and the initial angle when the display 120 is in the second posture (eg, portrait posture) is 90 degrees may be preset.

In addition, when the controller (not shown) rotates the display 120 in the first posture to the second posture, the rotation angle of the display 120 is added by adding the rotation angle of the display 120 to the initial angle of 0 degrees. information can be obtained. For example, as described above, when the rotation angle of the display 120 rotated by the motor 130 per pulse is 0.01125 degrees, the controller (not shown) outputs 10 pulse signals, the display is displayed at an initial angle of 0 degrees It may be determined that 0.1125 degrees obtained by adding up 0.1125 degrees, which is the rotation angle of 120 , is the rotation angle of the display 120 .

If the display 120 in the second posture is rotated to the first posture, the controller (not shown) subtracts the rotated angle of the display 120 from the initial angle of 90 degrees to thereby rotate the display 120 . information can be obtained. For example, as described above, when the rotation angle of the display 120 rotated by the motor 130 per 1 pulse is 0.01125 degrees, the controller (not shown) outputs 10 pulse signals, the display is displayed at an initial angle of 90 degrees 89.8875 degrees obtained by subtracting 0.1125 degrees, which is the rotation angle of 120 , may be determined as the rotation angle of the display 120 .

In addition, the controller (not shown) may transmit information on the rotation angle of the display 120 to the processor 140 . Specifically, the controller (not shown) may transmit information on the rotation angle of the display 120 obtained while the display 120 is rotated to the processor 140 electrically connected to the controller (not shown).

And, while the display 120 is rotated, the processor 140 receives information about the rotation angle of the display 120 from a controller (not shown), and receives information about the rotation angle of the display 120 that is changed according to the rotation. The display 120 may be controlled to rotate and display the image content based on the information.

Specifically, when the display 120 is rotated from the first posture to the first direction, the processor 140 rotates and displays the image content in the second direction based on the information on the rotation angle of the display 110 . When the display 120 is controlled and the display 120 is rotated in the second direction from the second posture, the image content is rotated and displayed in the first direction based on the information on the rotation angle of the display 120 . The display 120 may be controlled.

For example, when the display of the first image content through the display 120 in the first posture is completed, the processor 140 may display the second image content through the display 120 in the first posture as shown in FIG. 5 . may be displayed (refer to 510 of FIG. 5 ). Then, when the display 120 is rotated by the angle A in the first direction, the processor 140 rotates the image content by the angle A in the second direction and displays the rotated image content through the rotated display 120 . (refer to 520 of FIG. 5) can be done. Then, when the rotation of the display 120 in the second posture is completed, the processor 140 may display the second image content through the display 120 in the second posture (refer to 530 of FIG. 5 ).

Accordingly, even while the display 110 rotates, the user may be provided with image content that is horizontal to the ground, for example, instead of image content that is inclined.

By controlling the motor connected to the driving unit so that the 120 is moved to the first position, the display 120 is moved to the first position, and the first image content 610 can be displayed through the display 120 at the first position. there is.

Then, after displaying the first image content 610 through the display 120 at the first position, the processor 140 displays the second image content based on the location information of the display corresponding to the second image content. location can be determined. In addition, when the position for displaying the second image content is the second position outside the object, the processor 140 controls the motor connected to the driving unit to move the display 120 to the second position to generate the display 120 . It is moved to the second position, and the second image content 620 may be displayed through the display 120 at the second position.

Meanwhile, the location information of the display included in the schedule information may be different depending on the type of image content. Specifically, if the type of image content is the first type, the position of the display corresponding to the image content may be set to a first position suitable for providing the first type of image content, and the type of image content is the second type In this case, the position of the display corresponding to the image content may be set to a second position suitable for providing the second type of image content. Here, the setting of the location may be based on a user command input to the server.

For example, when the image content is content for advertisement of a product for children, the position of the display corresponding to the image content may be a position where children can see the display in an area frequently visited by children, such as a kindergarten, and the image content is a movie In the case of content for advertisement, the position of the display corresponding to the image content may be a position where the display can be viewed in an area where a movie theater or the like is located.

Also, the location information of the display included in the schedule information may be different depending on the floating population of the area in which the display apparatus 100 is installed. Specifically, when there is a relatively large floating population in the first area in the first time period, the location information of the image content in the first time period may be set to a first location suitable for providing the image content to the first area. and when there is a relatively large floating population in the second area in the second time period, location information of the image content in the second time period may be set to a second location suitable for providing the image content to the second area. .
