In order to make the content of this disclosure more comprehensible, the following embodiments are specifically cited as examples on which this disclosure can indeed be implemented. In addition, wherever possible, elements/components/steps with the same reference numbers in the drawings and embodiments represent the same or similar components.

FIG. 1A is a schematic diagram of the system architecture of an aerial imaging system according to an embodiment of the present invention. FIG. 1B is a top view of an aerial imaging system according to an embodiment of the invention. 1A and 1B at the same time, the aerial imaging system 100 includes a plurality of pixel units 110 (such as pixel units 110_1 to 110_9). The pixel units 110 are preset to be arranged in an array on the plane GS (for example, the ground or the desktop, etc.). Each pixel unit 110 includes an imaging unit 112 and a driving unit 114. The imaging part 112 and the driving part 114 are coupled to each other along a first direction D1, wherein the first direction D1 is parallel to the normal direction NL of the plane GS, And the driving part 114 will be located on the side facing the plane GS. Here, if the plane GS is the ground, the first direction D1 can be, for example, the z-axis direction in space (the X-Y plane in the space is the ground), but the invention is not limited to this.

In this embodiment, the driving portion 114 of each pixel unit 110 generates a driving force according to the received pixel data, so as to push the corresponding imaging portion 112 to move in the first direction D1, thereby creating an image in the air. More specifically, in each pixel unit 110, at least the imaging part 112 floats/floats on the plane GS, that is, there is at least a gap height between the imaging part 112 and the plane GS, and is not supported by physical objects. The interval height is determined according to the driving force generated by the driving part 114. The stronger the driving force, the higher the interval height between the pixel unit 110 and the plane GS, that is, the farther away from the plane GS; The weaker the driving force, the smaller the distance between the pixel unit 110 and the plane GS, that is, the closer the distance from the plane GS is.

In the application of the floating control pixel unit 110, by giving suitable pixel data, each pixel unit 110 can float at different heights in response to the pixel data, so that the entire pixel unit 110 can form a physical three-dimensional image. . The physical three-dimensional image described here is relative to the general projection type or parallax type three-dimensional image. The three-dimensional image created by the floating pixel unit 110 of this embodiment is physical and can be used by the user from space. Viewed from different angles (different visual presentations from different angles), and can be actually touched; while non-physical stereoscopic images such as general projection or parallax can only be viewed from a specific angle and are composed of light , Cannot be actually touched.

It should be noted that the driving part 114 and the imaging part 112 of this embodiment The physical structure of the device may be set together or separately according to the driving mode it is applied to. In other words, the present invention does not limit the driving portion 114 to float along the imaging portion 112 in the first direction D1. The driving portion 114 may be a solid member fixed on the plane GS, or a solid member that floats/floats along the first direction D1 along with the imaging portion 112, and the present invention is not limited thereto.

More specifically, taking the pixel units 110_1 and 110_2 shown in FIG. 1A as an example, in this embodiment, when the pixel units 110_1 and 110_2 are not driven, both will be placed on the plane GS, meaning That is, the distance between the pixel units 110_1 and 110_2 and the plane GS at this time is zero. When the driving parts of the pixel units 110_1 and 110_2 receive pixel data, the pixel unit 110_1 generates a driving force F1 in response to the received pixel data, and the pixel unit 110_2 generates a driving force F2 in response to the received pixel data. Among them, the driving forces F1 and F2 are over-distance forces/non-contact forces, and are applied on the plane GS, so that the pixel unit 110_1 reacts to the driving force F1 acting on the plane GS to generate a gap height d1, and the pixel unit 110_2 reacts The gap height d2 is generated by the driving force F2 acting on the plane GS. With the driving method, each pixel unit 110 can be

In this embodiment, the imaging part 112 may be formed of a luminous body (such as a light-emitting diode) or a non-luminous body, and the invention is not limited thereto. If the imaging part 112 is composed of a light-emitting body, the pixel unit 110 can not only exhibit a floating height gradient change, but also can cooperate with the brightness change of the light-emitting body to further present a three-dimensional display image.

In order to further explain the aerial display system 100 of the embodiment of the present invention For the imaging method, the 3×3 pixel units 110_1 to 110_9 in the area RP shown in FIG. 1B are taken as an example to further illustrate the screen display process when the pixel units 110_1 to 110_9 are taken as a whole, as shown in FIG. 1C. 1C is a side view of an aerial imaging system according to an embodiment of the invention.

Please refer to FIG. 1C. In this embodiment, the pixel data received by the pixel units 110_1 to 110_9 corresponds to the number "4", for example. At this time, the pixel units 110_1 and 110_3 will receive the same pixel data and generate the same or similar driving force to float at a position with a height d1 from the plane GS. The pixel units 110_4 to 110_6 will receive the same pixel data, and generate the same or similar driving force to float at the position of the interval height d2 from the plane GS, where the interval height d2 is smaller than the interval height d1. The pixel unit 110_9 generates a driving force according to the received pixel data, and accordingly floats at the position of the interval height d3 from the plane GS, wherein the interval height d3 is smaller than the interval height d2. In addition, the pixel units 110_2, 110_5, and 110_7 are not driven and are still located on the plane GS (that is, the interval height is 0). Based on this, the pixel units 110_1, 110_3~110_6 and 110_9 will form a number "4" floating in the air.

In this embodiment, the driving force may be, for example, magnetic buoyancy, air buoyancy, and acoustic buoyancy, etc., which can be generated and quantitatively controlled by electric circuits or mechanical elements. Below, FIGS. 2 to 4 are used to illustrate the formation of the driving force in different embodiments and the corresponding configuration of the driving portion 114.

2A is a schematic diagram of the structure of the pixel unit according to the first embodiment of the present invention. 2B is a schematic diagram of the physical structure configuration of the pixel unit according to the first embodiment of the present invention. Please refer to FIG. 2A first. In this embodiment, the pixel unit 210 includes an imaging unit 212 and a driver Section 214, wherein the imaging section 212 includes a light emitting element EU and a light emission control circuit ED, and the driving section 214 includes a power conversion circuit PCV and a superconductor element SPC.

In the imaging section 212, the light emitting element EU may be, for example, a light emitting diode (LED). The light emitting control circuit ED is coupled to the light emitting element EU to provide a light emitting control signal to the light emitting element EU, so that the light emitting element EU can emit light in response to the received light emitting control signal. Here, the light emission control circuit ED may be, for example, a light emission control means with controllable brightness such as a PWM control circuit.

In the driving part 214, the power conversion circuit PCV is coupled to the light-emitting control circuit ED to generate operating power for the light-emitting control circuit ED. The power conversion circuit PCV may be, for example, a buck converter (bulk converter) or a boost converter. A boost converter or a bulk-boost converter is not limited by the present invention. Among them, the plane GS will be provided with a component that generates a magnetic field, and the magnetic field energy of the magnetic field will have a corresponding relationship with the pixel data (this part will be further detailed in subsequent embodiments), so the superconductor element SPC can respond to the magnetic field associated with the pixel data The energy forms a reluctance force in the normal direction of the plane GS, which in turn causes the pixel unit 210 to float in the air and move along the normal direction of the plane GS.

2A and 2B at the same time, in terms of structural configuration, the superconductor element SPC, the power conversion circuit PCV, the light emitting control circuit ED, and the light emitting element EU can be stacked in a direction away from the plane GS in sequence. In other words, the superconductor element SPC will be arranged on the side facing the plane GS.

In an exemplary embodiment, the input power of the power conversion circuit PCV may be provided by a battery (not shown) disposed on the superconductor element. In another exemplary embodiment In this case, the pixel unit 210 may further include a wireless charging module WCM. The wireless charging module WCM can be, for example, a coil disposed on the superconductor element SPC, which can generate electric energy in response to changes in the magnetic field when the pixel unit 210 moves along the first direction D1. In this application, the power conversion circuit PCV performs power conversion according to the electric energy generated by the wireless charging module WCM, so as to generate working power for the light-emitting control circuit ED.

In detail, the superconductor element SPC can be, for example, chemical material superconductors (such as lead and mercury), alloy material superconductors (such as niobium-titanium alloy and niobium-germanium alloy), oxide superconductors (such as yttrium barium copper oxide), and organic superconductors (such as Fullerenes and carbon nanotubes) one of them. Among them, the superconductor element SPC will repel all the magnetic flux in the superconducting state, so that the lines of magnetic force cannot penetrate the superconductor element SPC, so that the superconductor element SPC generates magnetic resistance (ie, the Meissner effect) against the magnetic field.

The specific operation of the aerial imaging system using the pixel unit 210 is further illustrated in conjunction with FIG. 2C. 2C is a schematic diagram of the system architecture of the aerial imaging system using the pixel unit of the first embodiment of the present invention.

2A to 2C, the three-dimensional imaging system of this embodiment may further include a floating driving circuit FD, which is configured on the plane GS corresponding to the pixel unit 210 and can be used to convert the image data DTA into electromagnetic energy. Specifically, the floating driving circuit FD includes a plurality of electromagnetic units 220, a timing driving circuit 230, and a data conversion circuit 240. The electromagnetic unit 220 is arranged in an array and is disposed between the pixel unit 210 and the plane GS corresponding to the pixel unit 210. For example, the electromagnetic unit 220_1 is configured corresponding to the pixel unit 210_1, and the electromagnetic unit 220_2 is 210_2 corresponds to the configuration. That is, when the pixel units 210_1 and 210_2 are not driven, they are located on the electromagnetic units 220_1 and 220_2, respectively, and the configuration of the other pixel units 210 and the electromagnetic unit 220 can be deduced by analogy. Wherein, the electromagnetic unit 220 may be, for example, an electromagnet that can generate a corresponding magnetic field according to an electric signal, but the present invention is not limited to this.

The timing driving circuit 230 is coupled to the electromagnetic unit 220 and used to sequentially activate the electromagnetic unit 220. The data conversion circuit 240 is coupled to the electromagnetic unit 220. The data conversion circuit 240 is used to convert the pixel data DTA into a plurality of driving voltages E_DTA, and cooperate with the activation timing of the electromagnetic unit 220 to sequentially provide the driving voltage E_DTA to the corresponding electromagnetic unit 220. Wherein, the electromagnetic unit 220 generates corresponding electromagnetic energy in response to the received driving voltage E_DTA.

In detail, referring to FIG. 2C, the timing driving circuit 230 can sequentially activate the electromagnetic units 220 in the first row to the fourth row, and then return to the first row after the electromagnetic units 220 in the fourth row are activated. The electromagnetic unit 220 reciprocates in this way. When the electromagnetic unit 220 is enabled, it can generate corresponding magnetic field energy in response to the received driving voltage E_DTA, thereby causing the corresponding pixel unit 210 to generate a corresponding magnetic reluctance. Conversely, even if the electromagnetic unit 220 that is not enabled receives the driving voltage E_DTA, it will not create a magnetic field. By means of the sequence activation of the electromagnetic unit 220, the pixel unit 210 can generate the corresponding magnetic reluctance force column by column, thereby establishing an aerial image.

The mechanical flying element MFU is used to generate aerodynamic force through rotation, flapping, or jetting mechanism to move the pixel unit 310 to which it belongs in the normal direction of the plane. The rotation, wing flapping or PCM jet mechanism may be, for example, a propeller, a mechanical bird wing or a jet propulsion device, etc., and the present invention is not limited thereto. In addition, the mechanical flying element MFU may be, for example, an unmanned aerial vehicle (UAV).

The carrying platform PT is used to carry the imaging part 312. In a specific application, the light-emitting element EU may be attached to the carrying platform PT, for example. The power component PCM can be, for example, a motor, which can be used to drive the rotor component WC to rotate the rotor component WC to generate an airflow in the first direction D1, thereby generating air buoyancy so that the rotor component WC can float in the air with the movable carrier platform PT. Wherein, through the driving capability of the programmed power component PCM (for example, adjusting the motor speed), the carrier platform PT can drive the imaging part 312 to float to a preset position on the plane GS, thereby realizing aerial imaging.

The parts of the light-emitting element EU, the light-emitting control circuit ED, and the power supply circuit PU are the same as those in the previous embodiment, and will not be repeated here. The acoustic wave driving module SDM is used to establish a acoustic wave field in the first direction D1. Among them, since the standing wave point in the acoustic wave field has no net energy transfer, the effect of the gravity of the light-emitting element EU will be offset by the pressure of the acoustic wave, so the acoustic wave drive module SDM can adjust the standing wave point of the acoustic wave field In turn, the pixel unit 410 to which it belongs is moved in the first direction D1.

4B is a schematic diagram of the physical structure configuration of the pixel unit according to the third embodiment of the present invention. Referring to FIGS. 4A and 4B at the same time, the acoustic wave driving module SDM of this embodiment includes two acoustic wave generating elements SWG1 and SWG2. The two sound wave generating elements SWG1 and SWG2 are symmetrically arranged on both sides of the imaging section 412 of the corresponding pixel unit 410 along the first direction D1. Among them, the sound wave generating elements SWG1 and SWG2 respectively generate standing wave signals SW1 and SW2 having the same frequency, and then a standing wave point is formed at a specific node between the sound wave generating elements SWG1 and SWG2. Based on this, the floating position of the imaging part 412 can be adjusted by adjusting the output wavelengths of the sound wave generating elements SWG1 and SWG2.
