[0015] Optionally, the display panel further includes a PCB board, on which a plurality of grooves are provided as the positions of the pixels, and the sidewalls of the grooves have the interface;

[0016] The rotatable unit includes a rotating shaft, a micro motor, and a flap. The rotating shaft is located at the opening of the groove, and one side of the flap is connected to the rotating shaft. The micro motor is used to drive the rotating shaft to rotate.

[0018] Generate the first control command, the second control command, and the third control command based on display requirements;

[0019] The first control command is used to control the rotatable unit at the first pixel position and the second pixel position to rotate to the second position, so that the pixel unit at the first pixel position falls onto the guide rail trolley;

[0020] The second control command is used to control the guide rail trolley to move to the second pixel position;

[0021] The third control command is used to control the lifting unit at the second pixel position to rise from the first state to the second state, so that the pixel unit on the guide rail trolley on the support plate corresponding to the lifting unit is placed at the pixel position.

[0028] When the light intensity is not greater than the first intensity, or when the current time is in the second time period, the display requirement is determined to be to disperse the pixel units.

[0032] The beneficial effects of the technical solutions provided in this disclosure are:

[0033] In this embodiment, the display panel includes a lifting unit, a rotatable unit, a guide rail trolley, and a drive unit. The drive unit controls the lifting unit to move up and down, the rotatable unit to rotate, and the guide rail trolley to move. When the display panel is displaying an image, according to the display requirements, the drive unit controls the rotatable unit at the first pixel position to rotate. The pixel unit at the first pixel position detaches from its position and falls onto the guide rail trolley at the first pixel position. The guide rail trolley moves the pixel unit to the second pixel position, and the lifting unit moves the pixel unit to the second pixel position. Then, the rotatable unit at the second pixel position is rotated to fix the pixel unit, thus realizing the change of the pixel unit's position.

[0034] Since the number of pixel units in a display panel is less than the number of pixel positions, the pixel units can be concentrated in the high-precision display area required for the display, achieving localized high-precision and high-brightness display of the display panel. Alternatively, the pixel units in the display panel can be dispersed to achieve overall low-precision and low-brightness display of the display panel. Attached Figure Description

[0046] Figure 11 This is a flowchart of a control method for a display panel provided in an embodiment of the present disclosure. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a partial cross-sectional view of a display panel provided in an embodiment of this disclosure. See also... Figure 1The display panel includes: multiple display units 101, a guide rail trolley 102, multiple lifting units 104, and a drive unit 105;

[0049] Each display unit 101 has a plurality of pixel positions 106, and each display unit 101 includes a plurality of pixel units 107, a plurality of interfaces 110 and a plurality of rotatable units 108. Each pixel position 106 is arranged with one interface 110 and one rotatable unit 108. The number of pixel positions 106 in each display unit 101 is greater than the number of pixel units 107.

[0050] When the rotatable unit 108 rotates to the first position, the pixel position 106 has the pixel unit 107, and the pixel unit 107 is electrically connected to the interface 110; when the rotatable unit 108 rotates to the second position, the pixel position 106 does not have the pixel unit 107.

[0051] Each pixel unit 107 is arranged opposite to a lifting unit 104, and the lifting part of the lifting unit 104 is connected to a support plate 103.

[0052] When the plurality of lifting units 104 are in the first state, the surface of the support plate 103 corresponding to the plurality of lifting units 104 constitutes the moving guide rail of the guide rail trolley 102; when the lifting unit 104 rises from the first state to the second state, the pixel unit 107 on the guide rail trolley 102 on the support plate 103 corresponding to the lifting unit 104 is placed in the pixel position 106.

[0053] The drive unit 105 is used to drive the rotatable unit 108 to rotate between a first position and a second position, drive the guide rail trolley 102 to move on the moving guide rail, and drive the lifting unit 104 to lift.

[0054] In this embodiment, the display panel includes a lifting unit 104, a rotatable unit 108, a guide rail trolley 102, and a driving unit 105. The driving unit 105 controls the lifting unit 104 to lift, the rotatable unit 108 to rotate, and the guide rail trolley 102 to move. When the display panel is displaying an image, according to the display requirements, the driving unit 105 controls the rotatable unit 108 at the first pixel position to rotate, causing the pixel unit 107 at the first pixel position to detach from its position and fall onto the guide rail trolley 102. The guide rail trolley 102 moves the pixel unit 107 to the second pixel position, and the lifting unit 104 moves the pixel unit 107 to the second pixel position. Then, the rotatable unit 108 at the second pixel position is rotated to fix the pixel unit 107, thus realizing the change in the position of the pixel unit 107.

[0055] Since the number of pixel units 107 in the display panel is less than the number of pixel positions 106, the pixel units 107 can be concentrated in the high-precision display area required for the display, achieving local high-precision and high-brightness display of the display panel. Alternatively, the pixel units 107 in the display panel can be dispersed to achieve overall low-precision and low-brightness display of the display panel.

[0056] To ensure the separation and fixation of the pixel unit 107, the pixel position 106 and the guide rail carriage 102 are also provided with a magnetic structure, which is used to attract the pixel unit 107.

[0057] For example, the magnetic structure can be an electrically controlled magnetic structure that generates magnetic force when powered on and loses magnetic force when powered off. When the pixel unit 107 at the first pixel position moves away from the first pixel position, the magnetic structure at the first pixel position is de-energized, and the magnetic structure of the guide carriage 102 is energized. When the pixel unit 107 moves to the second pixel position, the magnetic structure at the second pixel position is energized, and the magnetic structure of the guide carriage 102 is de-energized.

[0058] Of course, the above magnetic structure is only one example, and other structures can also be used to achieve the detachment and fixation of pixel unit 107. This disclosure does not limit this.

[0059] In this embodiment, the display panel further includes a PCB board 109, on which a plurality of grooves are formed as pixel positions 106, and the sidewalls of the grooves have the interface 110. The grooves can penetrate the PCB board 109, with one side for the pixel unit 107 to pass through and the other side for the pixel unit 107 to emit light. Optionally, a transparent cover plate is provided on the other side of the groove.

[0060] Figure 2 This is a schematic diagram of the electrical connections of a display panel provided in an embodiment of this disclosure. See also... Figure 2 The display panel may also include a photosensitive unit 100, which can detect external light intensity so that the driving unit 105 can control the position of the pixel unit 107 based on the external light intensity.

[0061] like Figure 2 As shown, the photosensitive unit 100 is electrically connected to the driving unit 105. The driving unit 105 is also electrically connected to the guide rail trolley 102, the lifting unit 104, and the PCB board 109. The PCB board 109 is electrically connected to the pixel unit 107 and the rotatable unit 108.

[0062] In this embodiment of the disclosure, the lifting unit 104 may include a micro motor and a worm gear structure connected to the output shaft of the micro motor. One end of the worm gear structure is the lifting part of the lifting unit 104, which is used to connect with the support plate 103.

[0063] In one example, the micro motor in the lifting unit 104 may be a SQUIGGEL step-down micro motor, and an NSD2101 driver combined with the micro motor.

[0064] exist Figure 1 In the structure shown, each lifting unit 104 corresponds to a different support plate 103. The lifting part of the lifting unit 104 is fixedly connected to the support plate 103, and the support plate 103 moves with the lifting part. Multiple support plates 103 are spliced ​​together to form the track of the trolley.

[0065] In other implementations, the support plate 103 corresponding to each lifting unit 104 is the same, the lifting part of the lifting unit 104 is movably connected to the support plate 103, and the support plate 103 is fixed differently. The support plate 103 and the guide rail trolley 102 are provided with through holes for the lifting unit 104 to pass through, and the through holes through which the lifting unit 104 passes drive the pixel unit 107 to rise and fall.

[0066] Figure 3 This is a top view of the guide rail trolley. See also... Figure 3 The guide rail trolley 102 includes a guide rail trolley body 201 and a through hole 202 on the body. The guide rail trolley 102 has pulleys 203 at its four corners, which enable the guide rail trolley 102 to move on the support plate 103. The guide rail trolley 102 also includes a horizontal telescopic rod 204 and a vertical telescopic rod 205, which enable the guide rail trolley 102 to move.

[0067] For example, retaining walls are provided around the active area of ​​the guide rail trolley 102. One end of the horizontal telescopic rod 204 and the vertical telescopic rod 205 are fixedly connected to the main body 201 of the guide rail trolley, and the other end of the horizontal telescopic rod 204 and the vertical telescopic rod 205 are movably connected to the retaining walls. Here, the movable connection can refer to a connection method in which the end is engaged in a sliding groove in the retaining wall. In this way, when the horizontal telescopic rod 204 extends or retracts, it can drive the guide rail trolley 102 to move laterally, and at the same time drive the vertical telescopic rod 205 to move; when the vertical telescopic rod 205 extends or retracts, it can drive the guide rail trolley 102 to move vertically, and at the same time drive the horizontal telescopic rod 204 to move.

[0068] Both the horizontal telescopic rod 204 and the vertical telescopic rod 205 are electrically connected to the drive unit 105.

[0069] In this embodiment of the present disclosure, the driving unit 105 controls the extension and retraction of the telescopic rod connected to the guide rail trolley 102. The extension and retraction of the telescopic rod drives the guide rail trolley 102 to move along the horizontal and vertical directions, thereby enabling the guide rail trolley 102 to reach any pixel position 106 within the area.

[0070] For example, the horizontal telescopic rod 204 and the vertical telescopic rod 205 can be Junduo ELS series electric linear slides.

[0071] The Junduo ELS series electric linear slide uses a ball screw drive, which converts the rotational motion of the screw into the linear motion of the telescopic part of the Junduo ELS series electric linear slide. The Junduo ELS series electric linear slide has a positioning accuracy of 0.005mm and a repeatability of ±0.001mm, enabling precise movement of the pixel unit 107.

[0072] In the illustrated example, the through hole 202 of the guide carriage 102 is cylindrical. In other examples, the through hole 202 of the guide carriage 102 can be other shapes, such as pentagonal prisms, hexagonal prisms, etc.

[0073] In other implementations, the guide rail carriage 102 can also be a carriage without through holes, and other structures and Figure 3 The small car in the picture is the same.

[0074] In this embodiment of the disclosure, the driving unit 105 may be an integrated circuit or other circuit structure.

[0075] In this embodiment of the disclosure, the pixel unit 107 includes a light-emitting subunit and a driving subunit electrically connected to the light-emitting subunit, the driving subunit being further configured to be electrically connected to the interface 110.

[0076] In this embodiment, the size of the light-emitting subunit can be 100 micrometers * 100 micrometers, and the size of the driving subunit can be 200 micrometers * 200 micrometers. The pixel unit 107 with the above-mentioned dimensions can realize movement and other control.

[0077] In one possible implementation of this disclosure, the light-emitting subunit is an LED.

[0078] Figure 4 This is a schematic diagram of the structure of a pixel unit provided in an embodiment of this disclosure. See also... Figure 4 The pixel unit 107 includes a red LED 301, a blue LED 302, a green LED 303, and a driving subunit 304.

[0079] In another example, the pixel unit 107 may also include a white LED, etc.

[0080] Figure 5 This is a schematic diagram of the structure of an LED provided in an embodiment of this disclosure. See also... Figure 5 The LED includes a substrate 10, a two-dimensional material layer 11, an epitaxial layer and an electrode (not shown in the figure) stacked sequentially. The epitaxial layer includes a buffer layer 12, an N-type semiconductor layer 13, a quantum well layer 14, an electron blocking layer 15, a P-type semiconductor layer 16 and a P-type contact layer 17 stacked sequentially on the two-dimensional material layer 11.

[0081] For example, the substrate 10 can be a sapphire substrate, a self-supporting substrate, glass, diamond, etc., with a size ranging from 2 inches to 12 inches. The two-dimensional material layer 11 can be made of hexagonal boron nitride (hBN), graphene, etc., providing a lattice layer that facilitates subsequent epitaxial growth. The buffer layer 12 provides a smooth surface and a matching lattice layer, the N-type semiconductor layer 13 provides an electron supply region, the quantum well layer 14 is a region where electrons and holes recombine, the electron blocking layer 15 is used to regulate carrier distribution, the P-type semiconductor layer 16 provides a hole supply region, and the P-type contact layer 17 achieves ohmic contact with the P-type electrode.

[0082] LEDs of different colors can be achieved by combining phosphors of different colors with the above-mentioned LED structure.

[0083] Figure 5 The LED unit structure shown is only one example; LEDs may include more or fewer film layers.

[0084] In another possible implementation of this disclosure, the light-emitting subunit can be other light-emitting units.

[0085] Figure 6 This is a schematic diagram of the structure of a rotatable unit provided in an embodiment of this disclosure. See also... Figure 6 The rotatable unit 108 includes a micro motor 501, a flap 502, and a rotating shaft 503. The rotating shaft 503 is located at the opening of the groove, and one side of the flap 502 is connected to the rotating shaft 503. The micro motor 501 is used to drive the rotating shaft 503 to rotate.

[0086] When the micro motor 501 controls the rotation shaft 503 to rotate, it can control the flap 502 to rotate, thus moving from the first position to the second position.

[0087] In one example, the micro motor 501 can be a SQUIGGEL step-down micro motor.

[0088] Figure 7 This is a distribution diagram of display units in a display panel provided in an embodiment of this disclosure. See also... Figure 7Multiple display units 101 are arranged in an array. The display panel includes multiple photosensitive units 100.

[0089] like Figure 7 As shown, each set of 3*3 display units 101 arranged in a matrix corresponds to 2 photosensitive units 100, and the 2 photosensitive units 100 are located diagonally opposite each of the 3*3 set of display units 101 arranged in a matrix.

[0090] For example Figure 7 As shown, the two photosensitive units 100 are located at the upper left and lower right corners of the 3*3 matrix-arranged display units 101, respectively. This disclosure identifies external light intensity through the photosensitive units 100, and uses two photosensitive units 100 for dual identification to avoid identification anomalies. The two photosensitive units 100, located at the upper left and lower right corners of the 3*3 matrix-arranged display units 101, can improve the accuracy of light intensity identification.

[0091] In other examples, the photosensitive unit 100 can be located in the lower left corner and the upper right corner, respectively.

[0092] In another example, photosensitive units 100 can be arranged diagonally across a 5x5 matrix arrangement of display units 101.

[0093] In another example, each of the 3*3 or 5*5 matrix-arranged display units 101 can have more photosensitive units 100, such as 3, 4, etc.

[0094] Figure 8 This is a top view of a display panel provided in an embodiment of this disclosure. See also... Figure 8 The pixel units 107 in the display panel are distributed according to display requirements. Figure 8 In the scene shown, the pixel units 107 are unevenly distributed.

[0095] Figure 9 This is a top view of a display unit provided in an embodiment of this disclosure. See also... Figure 9 The display unit 101 has multiple pixel positions 106 and includes multiple pixel units 107.

[0096] like Figure 9 As shown, the display unit 101 has 8*8 pixel positions 106, and the ratio of the number of pixel units 107 to the number of pixel positions 106 is greater than 4 / 9. For example, each pixel unit 107 in the display unit 101 has an average of at least 3 pixel units 107 within a range of one pixel position 106.

[0097] In this disclosure, not all pixel positions 106 have pixel units 107; the number of pixel units 107 is less than the number of pixel positions 106, thus allowing the pixel units 107 to move. To ensure the display effect of the display panel, each display unit 101 has an average of at least three pixel units 107 within a range of one pixel position surrounding the pixel unit 107.

[0098] exist Figure 9 In the display unit 101 shown, the black area is where the pixel unit 107 is located, and 32 pixel units 107 are arranged in 64 pixel positions 106.

[0099] In this embodiment, the driving unit 105 can control the pixel unit 107 to move locally on the display panel, for example, within the area of ​​3*3 display units 101 arranged in a matrix. In this way, the movement of the pixel unit 107 takes less time and has less impact on the display. Furthermore, this method can also achieve the effect of pixel concentration and dispersion.

[0100] Correspondingly, each of the 3*3 matrix-arranged display units 101 has a guide trolley 102.

[0101] In other implementations, the driving unit 105 can also control the global movement of the pixel unit 107 on the display panel.

[0102] Figure 10 A flowchart illustrating a control method for a display panel according to an embodiment of this disclosure. See also... Figure 10 The method includes:

[0103] 601. Generate the first control instruction, the second control instruction, and the third control instruction based on display requirements.

[0104] 602. The first control command is used to control the rotatable unit at the first pixel position and the second pixel position to rotate to the second position, so that the pixel unit at the first pixel position falls onto the guide rail trolley.

[0105] 603. The second control command is used to control the guide rail trolley to move to the second pixel position.

[0106] 604. The third control command is used to control the lifting unit at the second pixel position to rise from the first state to the second state, so that the pixel unit on the guide rail trolley on the support plate corresponding to the lifting unit is placed at the pixel position.

[0107] 605. The first control command is used to control the rotatable unit at the second pixel position to rotate to the first position.

[0108] In this embodiment of the present disclosure, when the display panel displays an image, according to the display requirements, the driving unit 105 controls the rotatable unit 108 at the first pixel position to rotate, and the pixel unit 107 at the first pixel position detaches from the first pixel position and falls onto the guide trolley 102 at the first pixel position. The guide trolley 102 moves the pixel unit 107 to the second pixel position, and the lifting unit 104 moves the pixel unit 107 to the second pixel position. Then, the rotatable unit 108 at the second pixel position is rotated to fix the pixel unit 107, thereby realizing the change of the position of the pixel unit 107.

[0109] Since the number of pixel units 107 in the display panel is less than the number of pixel positions 106, the pixel units 107 can be concentrated in the high-precision display area required for the display, achieving localized high-precision and high-brightness display of the display panel. Alternatively, the pixel units 107 in the display panel can be dispersed to achieve overall low-precision and low-brightness display of the display panel.

[0110] The display panel provided in this embodiment can be a micro-display panel, for example, used in the fields of augmented reality (AR) or virtual reality (VR).

[0111] Figure 11 A flowchart illustrating a control method for a display panel according to an embodiment of this disclosure. See also... Figure 11 The method includes:

[0112] 701. Obtain the external light intensity collected by the photosensitive unit.

[0113] When the display panel displays an image, the driving unit 105 periodically acquires the external light intensity collected by the photosensitive unit 100.

[0114] For example, the driving unit 105 acquires the external light intensity collected by the photosensitive unit 100 once every 10 minutes.

[0115] As shown above, two photosensitive units 100 in every 3*3 display units 101 simultaneously acquire external light intensity. The driving unit 105 proceeds to the next step when the light intensity acquired by the two photosensitive units 100 is consistent, or when the difference in light intensity acquired by the two photosensitive units 100 is within a certain error range; if the light intensity acquired by the two photosensitive units 100 is inconsistent or exceeds the error range, the external light intensity recognition is performed again.

[0116] For example, the error range can be 0 to 5 lux. The above error range is only an example, and in actual situations, the error range can be adjusted.

[0117] The driving unit 105 has a timing function. It starts timing when the user uses the display panel. When the timing period is met, the external light intensity is detected. The photosensitive unit 100 starts timing again after each acquisition of external light intensity. After the timing period is met, the next external light intensity detection is performed. If the display panel enters a sleep state during timing, the timing stops and the timing duration is reset to zero. The timing starts again when the user uses the display panel again.

[0118] For example, when the user starts the display panel, the external light intensity is identified once and the current time is obtained, and then the timing starts. When the timing cycle is met, the light intensity is identified again and the current time is obtained. When the screen enters sleep mode, the timing stops and the timing duration is cleared to zero.

[0119] The photosensitive chip can identify the environment in which the display panel is working and make targeted adjustments to the brightness and display area, reducing the driving of unnecessary display units 101, reducing energy consumption, and also reducing light pollution.

[0120] 702. Obtain the display requirement based on at least one of the light intensity and the current time.

[0121] When the light intensity is greater than the first intensity, or when the current time is within the first time period, it is determined that the display requirement is to concentrate the pixel unit 107 to the high-precision display area;

[0122] When the light intensity is not greater than the first intensity, or when the current time is in the second time period, the display requirement is determined to be to disperse the pixel units 107.

[0123] For example, the first intensity can be 100 lux. The first intensity described above is only an example, and the first intensity can be set according to actual needs.

[0124] For example, the first time period can be 8:00-23:00, and the time outside the first time period is the second time period.

[0125] 703. Generate the first control instruction, the second control instruction, and the third control instruction based on display requirements.

[0126] When the display requirement is to concentrate the pixel units 107 to the high-precision display area, the driving unit 105 determines the position of the high-precision display area based on the image to be displayed; then, based on the position of the pixel units 107 in the display panel and the position of the high-precision display area, it generates a first control command, a second control command, and a third control command.

[0127] In this embodiment of the disclosure, a high-precision display area refers to a region in the image to be displayed where the differences between individual pixels are relatively large. For example, a solid color area in the image can be displayed with low precision, while an area with many colors and large differences in brightness between pixels can be displayed with high precision.

[0128] Therefore, a high-precision display area can be achieved by comparing the grayscale or chromaticity between adjacent pixels. Grayscale is determined based on the pixel's gray level, while chromaticity is determined based on the pixel's color coordinates.

[0129] In this embodiment of the disclosure, the display requirements of the display panel can be determined on a local basis, for example, on a 3*3 display unit 101 basis, to determine whether the pixel units 107 are concentrated in the high-precision display area or dispersed in the unit.

[0130] For example, taking 3*3 display units 101 as an example, the pixels in the image corresponding to the 3*3 display units 101 are compared with the grayscale difference or chromaticity difference of any adjacent pixels. If the grayscale difference or chromaticity difference between a pixel and multiple adjacent pixels (e.g., more than 80% of adjacent pixels) exceeds the threshold, the area of ​​the display panel corresponding to the pixel and the surrounding pixels is determined to be the high-precision display area.

[0131] Of course, the high-precision display area mentioned above is an example of a unit consisting of one pixel and all its adjacent pixels. In other implementations, the high-precision display area can be larger or smaller.

[0132] In other implementations, the display requirements of the display panel can also be based on the global display panel. This will not be elaborated upon here.

[0133] When determining the location of the high-precision display area, the position of the pixel unit 107 in the high-precision display area is determined, and the number and position of the missing pixel unit 107 are determined; then, the movable pixel unit 107 is determined from the movable range (e.g., 3*3 display units 101), and then the movable pixel unit 107 is matched with the pixel position 106 of the missing pixel unit 107; based on the matched movable pixel unit 107 and the pixel position 106 of the missing pixel unit 107, a first control instruction, a second control instruction, and a third control instruction are generated.

[0134] The movable pixel unit 107 can refer to a pixel unit 107 in which the number of pixel units 107 within a certain range exceeds the number of pixel units 107 in the dispersed case, and is randomly selected from these pixel units 107 as the movable pixel unit 107.

[0135] For example, if the movable pixel unit 107 is located at position 1, and the pixel position 106 that is missing the corresponding pixel unit 107 is located at position 2, then the first control command is to open the rotatable unit 108 at positions 1 and 2, that is, to control the rotatable unit 108 at positions 1 and 2 to rotate to the second position; the second control command controls the guide trolley 102 to move from position 1 to position 2; the third control command is used to control the lifting unit 104 at the position to rise from the first state to the second state; the first control command is also used to control the rotatable unit 108 at position 2 to rotate to the first position.

[0136] 704. The first control command is used to control the rotatable unit at the first pixel position and the second pixel position to rotate to the second position, so that the pixel unit at the first pixel position falls onto the guide rail trolley.

[0137] At this time, the driving unit 105 can also control the magnetic structure at the first pixel position to be de-energized and the magnetic structure of the guide rail trolley 102 to be energized through control commands.

[0138] Before the rotatable unit 108, which controls the first pixel position, rotates to the second position, the drive unit 105 can also control the guide trolley 102 to move to the first pixel position through the second control command.

[0139] Before the rotatable unit 108 controlling the first pixel position rotates to the second position, the drive unit 105 can also control the lifting unit 104 at the first pixel position to rise from the first state to the second state through a third control command.

[0140] 705. The second control command is used to control the guide rail trolley to move to the second pixel position.

[0141] Before the control guide trolley 102 moves, the drive unit 105 can also control the lifting unit 104 at the first pixel position to descend from the second state to the first state through the third control command.

[0142] 706. The third control command is used to control the lifting unit at the second pixel position to rise from the first state to the second state, so that the pixel unit on the guide rail trolley on the support plate corresponding to the lifting unit is placed at the pixel position.

[0143] At this time, the driving unit 105 can also control the magnetic structure at the second pixel position to be energized and the magnetic structure of the guide rail trolley 102 to be de-energized through control commands.

[0144] 707. The first control command is used to control the rotatable unit at the second pixel position to rotate to the first position.

[0145] Before the rotatable unit 108 is rotated to the first position, the drive unit 105 can also control the lifting unit 104 at the second pixel position to descend from the second state to the first state through a third control command.

[0146] During the above control process, if a car has multiple pixel units 107 that need to be moved, the drive unit 105 controls the car to move multiple pixel units 107 in sequence.

[0147] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
