The amount of information that can be obtained by visual means far exceeds the information available in other ways such as hearing, touch, smell and taste. the amount. The objects in reality are three-dimensional and three-dimensional. The visual system of the human eye can adapt well to the three-dimensional world in reality and accurately transmit image information to people. However, due to technical reasons, most of the current display devices can only display two-dimensional images, although they can also show people the multicolored world, but far from providing visual information compared with the real world. With the development of science and technology and the improvement of people's living standards, people's requirements for display devices are not limited to simply transmitting two-dimensional plane information, but hope that it can provide a more realistic, three-dimensional sense, closer to the actual human eye. The three-dimensional stereoscopic image information is felt, and the three-dimensional stereoscopic display technology emerges as the times require.

In the existing three-dimensional display technology, mainly based on parallax stereoscopic display technology. The so-called parallax stereoscopic display technology allows the viewer's left and right eyes to see different images through time multiplexing or spatial multiplexing, and the images seen by the viewer's two eyes are merged in the brain. The viewer perceives an image with a hierarchical depth of field. However, the existing stereoscopic display technology is limited by the angle that the viewer and the viewer can view, and cannot provide the features of naked-eye viewing, peripheral viewing, and image suspension touchability at the same time.

The present invention provides an aerial imaging system and a floating pixel unit that can provide a viewing experience different from conventional imaging systems.

The aerial imaging system of the present invention includes a plurality of pixel units. The pixel units are arranged in an array on the plane, wherein each of the pixel units includes an imaging portion and a driving portion, and the imaging portion and the driving portion are coupled to each other in a first direction, and the first direction and the normal direction of the plane are parallel to each other And the drive portion is located on the side facing the plane. The driving unit of each pixel unit generates a driving force according to the corresponding pixel data, thereby pushing the corresponding imaging portion to move in the first direction, thereby establishing an image in the air.

The floating pixel unit of the present invention is adapted to float in the air in a first direction orthogonal to the ground in response to magnetic field energy. The floating pixel unit includes a light emitting element, a light emission control circuit, a power conversion circuit, and a superconductor element. The illuminating control circuit is coupled to the illuminating component for providing an illuminating control signal to the illuminating component according to the operating power source, so that the illuminating component emits light in response to the received illuminating control signal. The power conversion circuit is coupled to the illumination control circuit to generate a working power supply for use in the illumination control circuit. The superconductor element is disposed on a side close to the ground for reacting with the magnetic field energy to form a magnetic resistance force in the first direction, thereby causing the pixel unit to float in the air and move in the first direction.

Based on the above, an embodiment of the present invention provides an aerial imaging system and a floating pixel unit, which are configured to display a stereoscopic image having a solid in the air by providing a pixel unit that can establish a driving force in a plane normal direction. Different from the non-physical stereoscopic display method such as the general projection type or the parallax type, the stereoscopic image created by the floating pixel unit of the embodiment is solid and can be viewed by the user from different angles in the space, and from different angles. Seeing different visual presentations will enhance the viewer's viewing experience.

Referring to FIG. 1A and FIG. 1B simultaneously, the aerial imaging system 100 includes a plurality of pixel units 110 (eg, pixel units 110_1 110 110_9). The pixel units 110 are preset to be arranged in an array on the plane GS (for example, ground or desktop, etc.). Each of the pixel units 110 includes an imaging portion 112 and a driving portion 114. The imaging portion 112 and the driving portion 114 are coupled to each other in the first direction D1, wherein the first direction D1 is parallel to the normal direction NL of the plane GS, and the driving portion 114 is located on a side facing the plane GS. Here, if the plane GS is the ground, the first direction D1 may be, for example, the z-axis direction in the space (the X-Y plane in the space is the ground), but the invention is not limited thereto.

In this embodiment, the driving unit 114 of each pixel unit 110 generates a driving force according to the received pixel data, thereby pushing the corresponding imaging unit 112 to move along the first direction D1, thereby establishing an image in the air. More specifically, in each of the pixel units 110, at least the image forming portion 112 floats/suspends on the plane GS, that is, at least one interval height between the image forming portion 112 and the plane GS, and is not supported by the physical object. The spacing height is determined according to the driving force generated by the driving portion 114. The stronger the driving force, the higher the height between the pixel unit 110 and the plane GS, that is, the farther from the plane GS; The weaker the driving force, the smaller the height between the pixel unit 110 and the plane GS, that is, the closer to the plane GS.

In the application of the floating control pixel unit 110, each pixel unit 110 can be made to float on different heights in response to the pixel data by giving appropriate pixel data, so that the pixel unit 110 can form a solid stereo image as a whole. . The stereoscopic image of the entity described herein is a stereoscopic image created by the floating pixel unit 110 of the present embodiment, which is solid and available to the user from the space. Viewing from different angles (different visual presentation from different angles), and can be touched by actual; while non-physical stereoscopic images such as projection or parallax are only visible from a specific angle and are composed of light Can't be actually touched.

It should be noted here that the physical structure of the driving portion 114 and the imaging portion 112 of the present embodiment may be set together or separately depending on the driving manner to which it is applied.

More specifically, taking the pixel units 110_1 and 110_2 shown in FIG. 1A as an example, in the embodiment, when the pixel units 110_1 and 110_2 have not been driven, both will be placed on the plane GS, That is, the pixel units 110_1 and 110_2 are at a height of 0 from the plane GS at this time. When the driving units of the pixel units 110_1 and 110_2 receive the pixel data, the pixel unit 110_1 generates the driving force F1 in response to the received pixel data, and the pixel unit 110_2 generates the driving force F2 in response to the received pixel data. Wherein, the driving forces F1 and F2 are super-distance/non-contact forces, and are applied to the plane GS, thereby causing the pixel unit 110_1 to react with the driving force F1 acting on the plane GS to generate the spacing height d1, and the pixel unit 110_2 reacts. The spacing height d2 is generated by the driving force F2 acting on the plane GS. By the driving manner, each pixel unit 110 can be

In this embodiment, the imaging unit 112 may be formed by an illuminant (for example, a light-emitting diode) or a non-illuminator. The invention is not limited thereto. If the imaging unit 112 is configured as an illuminant, the pixel unit 110 can display a stereoscopic display image in addition to the change in the gradation height of the illuminator.

In order to further illustrate the imaging mode of the aerial display system 100 according to the embodiment of the present invention, the 3x3 pixel units 110_1 110 110_9 in the region RP shown in FIG. 1B are taken as an example to further illustrate the screen when the pixel units 110_1 110 110_9 are integrated. The flow is shown as shown in Figure 1C. 1C is a side view of an aerial imaging system in accordance with an embodiment of the present invention.

Referring to FIG. 1C , in the embodiment, the pixel data received by the pixel units 110_1 110 110_9 may correspond to the number “4”, for example. At this time, the pixel units 110_1 and 110_3 receive the same pixel data and generate the same or similar driving force to float at a position spaced apart from the plane GS by a height d1. The pixel units 110_4~110_6 receive the same pixel data and generate the same or similar driving force to suspend the position at a height d2 from the plane GS, wherein 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 is suspended at a position spaced apart from the plane GS by a height d3, wherein the spacing height d3 is smaller than the spacing height d2. In addition, the pixel units 110_2, 110_5, 110_7 are not driven but are still on the plane GS (ie, the interval height is 0).

The electromagnetic unit 220, and thus reciprocates. When the electromagnetic unit 220 is enabled, it can generate a 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 resistance.
