< example one >

The present embodiment provides a display control method implemented by the above-described rotary display apparatus. As is apparent from the above description of the hardware configuration of the rotary display apparatus, the rotary display apparatus includes at least: the device comprises an upper part of the device and a base of the device, wherein the upper part of the device is provided with a display device which can be driven to rotate. The bottom of the device is provided with a driving motor for driving the display device.

As shown in fig. 2, the display control method provided in this embodiment includes the following steps S101 to S104:

and S101, responding to the received display trigger instruction, and determining a display starting position and a display switching position.

In this embodiment, the display triggering instruction is used to trigger the display device in the rotating display apparatus to rotate, and the display device switches the display content during the rotation. The display trigger instruction may be a button instruction generated based on a user triggering a start button on the rotating display device. When a plurality of microphones for collecting voice are further included in the rotary display device, the display trigger instruction may also be a voice instruction received by at least one of the plurality of microphones. The voice instruction may be, for example, a voice of "start", "start display", or the like uttered by the user. The display content may be a 2D image or a 3D image.

In this embodiment, after the rotating display device receives the display trigger instruction, the rotating display device may respond to the received display trigger instruction and determine the display start position and the display switching position. The display start position refers to a position at which the display apparatus starts to start displaying the display content. The display switching position is a position at which the display device switches from the currently displayed display content.

In one example, the manner of determining the display start position and the display switching position in S101 may be as follows:

s1011, the position of the display device when the display trigger command is received is used as the display start position.

In this embodiment, the position of the display device can be represented by a relative positional deviation from a reference position. The relative position deviation can be represented by the relative arc length and the relative rotation angle, and the reference position can be a preset position or a display initial position. Alternatively, the position of the display device may be represented by a relative rotation time with respect to the display start position.

In one example, the position of the display device when the display trigger instruction is received may be the position of the display device after each rotation stop.

And S1012, determining the display switching position of the display switching number according to the display initial position.

The display switching number is the number of display switching positions at which switching of display contents occurs during one rotation of the display device. The display switching number corresponds to the number of times that the display device switches the display content in the process of rotating for one circle, and can be set according to specific application requirements or application scenes.

Taking the example that the display device rotates 360 degrees in one rotation, the implementation manner of S1012 is as follows: and setting the display switching position according to the display starting position in a mode of uniformly dividing the display switching number by 360 degrees.

For example, when the display switching number is 2, it is necessary to set the display device to switch the display contents 2 times by one rotation, that is, it is necessary to set two display switching positions. And the display start position is normally used as the first display switching position. When the second display switching position is determined, the display device is equally divided by 360 degrees and 2 degrees, namely 180 degrees, the position where the display device is located at the display starting position and the display device is located at the subsequent 180-degree rotation position is determined as the display switching position.

When the display switching number is 4, the display device needs to be set to switch the display content 4 times by rotating one circle, that is, four display switching positions need to be set. And the display start position is normally used as the first display switching position. When the rest three display switching positions are determined, the display switching positions are equally divided according to 360 degrees and 4 degrees, namely, the display switching positions are respectively determined to be 90 degrees: the display device is located at the display starting position and at the position of the display device at every subsequent 90 degrees of rotation. Specifically, the display switching positions are sequentially: the position of the display device when rotated by 90 degrees with respect to the display start position, the position of the display device when rotated by 180 degrees with respect to the display start position, and the position of the display device when rotated by 270 degrees with respect to the display start position.

In this example, the position where the display device is located when the display trigger instruction is received is taken as the display starting position, so that when the rotating display device receives the display trigger instruction, the display device can be immediately set to directly display the display content corresponding to the display starting position. Therefore, the specific position of the display starting position does not need to be calculated, and the display speed of the display device can be improved.

In one example, the manner of determining the display start position and the display switching position in S101 may be: and analyzing the display trigger instruction, and acquiring a display starting position and a display switching position included in the display trigger instruction.

In this implementation, the display trigger instruction may include a display start position and a display switching position.

In an example, taking the display device rotating manner as a 360-degree rotation, when the rotating display device further includes a plurality of microphones for collecting voice, the specific implementation manner of the example may be: the user issues a display trigger instruction such as "start display" to rotate the display apparatus in response to the display trigger instruction, and takes a position where the display device is located when the display trigger instruction is received as a display start position, and positions where the display device is located when the display device is located at the display start position and rotated 180 degrees with respect to the display start position as display switching positions, respectively.

In this example, the user sends a display trigger instruction to the rotary display device according to his own needs. Therefore, the display starting position and the display switching position contained in the display triggering instruction can meet the requirements of the user, and therefore the personalized requirements of the user can be met when the rotary display equipment displays the display content.

In another example, taking the example that the display device rotates 360 degrees, the specific implementation manner of this example may also be: the user triggers a button which represents a trigger instruction for starting display on the rotary display device, the rotary display device responds to the display trigger instruction, the position of the display device when the display trigger instruction is received is taken as a display starting position, and the positions of the display device when the display device is located at the display starting position and rotates 180 degrees relative to the display starting position are respectively taken as display switching positions.

In one example, when the rotating display device further includes a plurality of microphones for capturing voice, the manner of determining the display start position and the display switching position in S101 may be further as follows in steps S1013 to S1015:

s1013, receiving the receiving state information of the display trigger instruction through a plurality of microphones, and determining the instruction source position of the display trigger instruction; wherein the reception state information includes at least a reception time difference.

In the present embodiment, the display trigger instruction is a voice instruction received through a plurality of microphones. In this example, S1011 described above may be implemented by a time-delay (TDE) -based sound source localization technique in a sound source localization algorithm based on a plurality of microphones. Of course, S1011 described above may also be implemented based on a maximum output power-based controllable beamforming technique or a high-resolution spectrogram estimation technique in a sound source localization algorithm using multiple microphones.

It should be noted that, in the sound source localization algorithm based on multiple microphones, a sound source localization technique based on time-delay estimation (TDE), a controllable beam forming technique based on maximum output power, and a high resolution spectrogram estimation technique are well known to those skilled in the art, and are not described herein again.

And S1014, determining a display starting position according to the instruction source position.

In implementing the above S1014, the instruction source position may be directly used as the display start position. Alternatively, a pre-acquired offset may be added to the instruction source position as the display start position. Based on the latter implementation, the rotary display device can achieve better display effect.

And S1015, determining the display switching position of the display switching number according to the display initial position.

The specific implementation manner of S1015 here is the same as that of S1012 described above, and is not described here again.

In this example, the instruction source position is used as the display start position, so that the user at the instruction source position can view the display content without adjusting the position of the user.

After the display start position and the display switching position of the display apparatus are acquired by the above-described step S101, the process proceeds to:

and S102, driving the display device to rotate through the driving motor, and acquiring the real-time position of the display device in the driving and rotating process.

In the embodiment, the display device may be an LCD display screen, an LED display screen, or the like. Meanwhile, when the display device is driven to rotate by the driving motor, the driving motor needs to have a certain motor speed.

In one example, the motor speed may be set at a fixed speed, such as 3600RPM (i.e., 60 Hz).

In one example, the motor speed may also be set according to the following steps:

and setting the rotating speed of a motor for driving the display device to rotate by a driving motor according to the display refreshing frequency, the display switching number and the lowest rotating speed threshold of the display device.

In this example, the rotation speed minimum threshold is a lower limit threshold of the rotation speed of the motor set in the present embodiment.

The lower limit threshold of the motor rotation speed is the lowest motor rotation speed which ensures that human eyes see a complete display content of one frame and cannot see the trailing of the picture of the display content of the previous frame or cannot see the fuzzy display content of the previous frame in the process of driving the display device to rotate by the driving motor. Generally, human vision has a persistence effect that causes human vision to stay at 0.1s-0.4s, corresponding to a minimum 24Hz response frequency of the human brain to the display content. If the frequency corresponding to the motor rotating speed is greater than the response frequency of the human brain to the display content, the human eyes can not perceive the refreshing of the display content picture and always see the complete display content of a single previous frame, otherwise, the frequency corresponding to the motor rotating speed is lower than the response frequency of the human brain to the display content, and the human eyes can perceive the trailing of the picture of the previous frame of display content or perceive the fuzzy residue of the previous frame of display content when the display content picture is refreshed. Therefore, in this embodiment, the rotation speed corresponding to 24Hz (i.e. 1440RPM) may be set as the minimum threshold of the rotation speed, so as to ensure that the rotation speed of the motor is not lower than 24Hz, and when the driving motor drives the display device to rotate at the rotation speed of the motor, when the display content is refreshed, human eyes cannot perceive the trailing of the frame of the previous frame of display content or perceive the blur residue of the previous frame of display content, and can always see the complete display content of the current frame.

Further, when the display switching number is K and the refresh frequency of the display device is F, in order to ensure that the display device rotates one turn and can display different display contents of K frames, the rotation speed of the motor for driving the display device to rotate by the driving motor is less than or equal to F/K × 60.

Based on the above, the specific way to determine the motor rotation speed in this example is as follows: and setting the lower limit of the motor rotation speed as the rotation speed minimum threshold value, and setting the upper limit of the motor rotation speed as F/K60.

Taking F as 120Hz and K as 2 as an example, the rotation speed of the motor for driving the display device to rotate by the motor is set to be 1440RPM to 3600 RPM.

Taking F as 120Hz and K as 4 as an example, the motor speed for driving the motor to drive the display device to rotate is set to be 1440RPM to 1800 RPM.

Taking F as 120Hz and K as 6 as an example, the rotation speed of the motor for driving the motor to drive the display device to rotate is set to be less than 1200RPMM in the manner described above. However, as can be seen from the above, the rotation speed minimum threshold of the motor rotation speed is 1440RPM, and the set motor rotation speed in this example is less than 1200RPM, i.e., less than the rotation speed minimum threshold, which obviously does not satisfy the conditions required to be satisfied by the motor rotation speed according to the present embodiment. That is, when F is 120Hz, K cannot be set to 6, and K can be adjusted from 6 to 4.

In the present embodiment, the above-mentioned step S102 can be implemented by the following steps S1021 and S1022:

and S1021, acquiring the rotating speed of the motor for driving the motor to drive the display device to rotate.

In one example, the motor speed for driving the motor to rotate the display device may be a preset speed, such as a fixed speed described above. Or setting the rotation speed of a motor for driving the display device to rotate by the driving motor according to the display refreshing frequency, the display switching number and the rotation speed minimum threshold of the display device.

In one example, the rotation speed of the motor for driving the display device to rotate by the driving motor may also be a rotation speed output by a speed measuring device arranged on the rotary display device for detecting the rotation speed of the motor for obtaining the driving motor.

In this example, as shown in fig. 3, the speed measuring device includes a photointerrupter and a shielding sheet; the shielding piece is arranged at the edge of a motor turntable of the driving motor and rotates along with the driving motor; the photointerrupter is arranged below a motor turntable of the driving motor; the photointerrupter is provided with a groove body which is opened upwards and through which the shielding piece can pass; the photointerrupter is used for outputting a speed measurement signal when the shielding piece rotates once along with the driving motor and passes through the groove body.

Illustratively, the photointerrupter may be an infrared photointerrupter, and the corresponding shielding sheet is an infrared shielding sheet.

In this example, the above S1021 can be realized by the following steps a and b:

a. and receiving a speed measurement signal output by the photointerrupter.

b. And acquiring the motor rotating speed of the driving motor according to the time difference between the two latest speed measurement signals received currently.

Specifically, when the time difference in step b is represented by Δ t (unit: s) and the motor rotation speed is represented by n (unit: RPM), n is 60/Δ t.

Based on the example, the accurate motor speed can be obtained, so that the accurate real-time position determined based on the accurate motor speed can be obtained subsequently.

S1022, acquiring a real-time position according to the rotating speed of the motor and the rotating time of the display device; wherein the rotation time of the display device is a time between a time when the display device has rotated past the reference position most recently to a time when the real-time position is acquired.

In this step, the real-time position may be represented by a relative positional deviation from a reference position. The reference position may be a preset position or a display start position. And the relative position deviation can be expressed by relative rotation angle and relative rotation arc length.

For example, when the reference position is the display start position and the relative position deviation is expressed by the relative rotation angle, the specific implementation manner of S1022 described above is: real-time position is time of rotation 360 °/(60/n).

Correspondingly, the display start position and the display switching position in S101 described above are also represented by relative positional deviations from the reference position.

Continuing with the reference position as the display start position, and the relative position deviation is expressed by the relative rotation angle as an example, the display start position can be expressed as: 0 deg. When the display switching number is 2, the corresponding display switching positions are respectively expressed as: 0 degrees and 180 degrees. When the display switching number is 4, the corresponding display switching positions are respectively expressed as: 0 °, 190 °, 180 °, 270 °.

In this embodiment, the step S102 may be further implemented by:

and acquiring the time between the moment when the display device passes the display initial position for the last time and the moment when the real-time position is acquired currently as the relative rotation time of the real-time position relative to the display initial position as the real-time position.

In this step, the real-time position is represented by a relative rotation time with respect to the display start position. At this time, the display start position is marked as 0.

Correspondingly, the display switching position is also indicated by a relative rotation time with respect to the display start position. Based on this, the determination of the display switching position in S101 can be realized by the following step S1016:

and S1016, setting the relative rotation time of each display switching position relative to the display initial position according to the motor speed and the display switching number of the display device driven by the driving motor to rotate, and obtaining the display switching position.

S1061 is described, taking an example where the motor rotation speed is 3600RPM and the display device is rotated 360 degrees in one rotation:

when the display switching number K is 2, it is known from the motor rotation speed and the display switching number that 1/(3600RPM/60Hz) ═ 16.7ms is required to drive the motor to drive the display device to rotate for 360 degrees. The driving motor drives the display device to rotate 180 degrees, which requires 16.7ms/2 to 8.35 ms. Correspondingly, the display start position is taken as the first display switching position, and 8.35ms rotated with respect to the display start position is taken as the second display switching position.

When the display switching number K is 4, it is known that 1/(3600RPM/60Hz) ═ 16.7ms is required to drive the motor to drive the display device to rotate once, based on the motor rotation speed and the display switching number. The driving motor needs 16.7ms/4 to 4.175ms for every 90 degrees of rotation of the display device. Correspondingly, the display start position is set as the first display switching position, 4.175ms is set as the second display switching position, 4.175ms 2-8.35 ms is set as the third display switching position, and 4.175ms 3-12.425 ms is set as the fourth display switching position.

Based on the above, the rotation speed of the motor for driving the motor to rotate the display device is recorded as a fixed rotation speed n. Taking the display switching number as 2 as an example, the specific implementation manner of S1016 is as follows: the first display start position is set to 0, the relative rotation time of the second display switching position with respect to the display start position is set to 60/2n equal to 30/n, and 30/n is set as the display switching position.

Taking the display switching number of 4 as an example, the specific implementation manner of S1016 is as follows: the first display start position is set to 0, the relative rotation time of the remaining display positions with respect to the display start position is (60/4n) × 1 ═ 15/n, 60/4n ═ 2 ═ 30/n, and 60/4n ═ 3 ═ 45/n, and 15/n, 30/n, and 45/n are set as the remaining display switching positions in this order.

After the real-time position of the display device driven to rotate is acquired in the above step S102, the process proceeds to the following steps S103 and S104:

and S103, when the real-time position is at the display initial position, setting the display device to start displaying the display content corresponding to the display initial position.

And S104, when the real-time position is at the display switching position, the display device is set to switch from the current display content, and the display content corresponding to the display switching position is displayed.

In one example, the display content corresponding to the display start position and the display content corresponding to the display switching position are sequentially stored in the memory of the rotary display device. Illustratively, when the display switching number is 2, the memory area sequentially stores: display content 1-1 corresponding to the first display switching position, display content 2-1 corresponding to the second display switching position, and display content 1-2 … … corresponding to the first display switching position

Based on the above, the implementation manner of S103 is: when the real-time position is at the display start position (i.e., the first display start position), the display apparatus is set to start displaying the display content 1-1 corresponding to the first display switching position.
