     BACKGROUND OF THE DISCLOSURE 
     Currently, many electronic products are capable of generating three-dimensional image information for being displayed on a flat-panel display. However, most of current audio and video information can only be played on the flat-panel display, which results in an inadequacy of a user perception. 
     Accordingly, how to convert general two-dimensional image information into three-dimensional image information that can be viewed and interacted with in real time has become one of the important issues to be solved in this field. 
     SUMMARY OF THE DISCLOSURE 
     In response to the above-referenced technical inadequacy, the present disclosure provides a floating three-dimensional image display system that receives a plurality of image information or a plurality of control signals. The floating three-dimensional image display system includes a controller and a first floating image display device. The first floating image display device is electrically connected to the controller. The controller generates the plurality of image information as a plurality of first floating image information according to the plurality of image information and a plurality of depth information, and displays the first floating image information in a space above a first side of the first floating image display device through the first floating image display device. 
     Therefore, one of the beneficial effects of the present disclosure is that the floating three-dimensional image display system is capable of receiving the image information provided by the electronic device and converting the same to display three-dimensional floating image information, so that a user experience can be expanded and a user can interact with the three-dimensional floating image information in real time.

The user can control the integrated floating image information GIN displayed in the space above the first floating image display device  14  by the first expansion gamepad EED 1  and the second expansion gamepad EED 2 . At this time, the first floating image display device  14  and the controller  11  of the floating three-dimensional image display system  1  can receive various image information or control information from the electronic device ED that is disposed at another location. In another embodiment, the first expansion gamepad EED 1  and the first floating image display device  14  can be designed as a single unit. The second expansion gamepad EED 2  and the first floating image display device  14  can also be designed as a single unit. In the present embodiment, the expansion connection module is a fixed connection component, but the present disclosure is not limited thereto. 
     In addition, the first floating image display device  14  and the controller  11  of the floating three-dimensional image display system  1  can also receive the image information provided by the server for display. 
     In  FIG. 8  and  FIG. 10 , the first floating image display device  14  and the second floating image display device  15  cooperate with electronic components such as the controller  11 , and are disposed in the casing at the same time. As shown in  FIG. 8  and  FIG. 10 , the second floating image display device  15  is disposed on one side of the first floating image display device  14 , and the second floating image display device  15  and the first floating image display device  14  can be folded together. 
     Reference is made to  FIG. 11 , in which  FIG. 11  is a schematic view of the floating three-dimensional image display system disposed in a casing according to the embodiment of the present disclosure. 
     Various electronic components of the floating three-dimensional image display system  1  are disposed in a casing  10 , which is openable and can be designed according to user requirements. 
     Reference is made to  FIG. 12  to  FIG. 16 , in which  FIG. 12  is a schematic structural view of the first floating image display device,  FIG. 13  is a schematic exploded view of the first floating image display device of the present disclosure,  FIG. 14  is a schematic view of lens arrays of the first floating image display device of the present disclosure that are relatively arranged,  FIG. 15  is a schematic view of lens arrays of the first floating image display device of the present disclosure that are staggeringly arranged, and  FIG. 16  is a schematic view of focusing through a single lens of the first floating image display device of the present disclosure. 
     The structure and the function of the second floating image display device  15  are similar to those of the first floating image display device  14 . Accordingly, only the first floating image display device  14  is described as an example below, and details of the structure and the function of the second floating image display device  15  are not reiterated herein. 
     The first floating image display device  14  includes a first display module  141 , a lens array layer  142  and a microstructure layer  143 . Through changing the image displayed, a stereoscopic image seen by a viewer can be changed according to a location of the viewer, so that the viewer can view the stereoscopic image at another location. 
     In addition, the microstructure layer  143  is a dynamic optical component layer. That is, the microstructure layer  143  has a microstructure function mode and a non-microstructure function mode. The microstructure layer  143  can be adjusted to the microstructure function mode or the non-microstructure function mode according to a control signal. When the microstructure layer  143  is switched to the microstructure function mode, it can be used to adjust an angle and a direction of light. When the microstructure layer  143  is switched to the non-microstructure function mode, the first floating image display device  14  is used for displaying the two-dimensional image information, instead of displaying the three-dimensional image information floating in the space on the one side of the first floating image display device  14 . However, in the present embodiment, the first floating image display device  14  can simultaneously display the two-dimensional image information and the floating image information. 
     The microstructure layer  143  is a liquid crystal lens array layer, which includes a plurality of microstructure liquid crystal lenses. The lens array layer  142  is also a liquid crystal lens array layer, which includes a plurality of optically adjusted liquid crystal lens. That is, the first floating image display device  14  is a display device including at least two liquid crystal lens array layers. In another embodiment, the first floating image display device  14  can include more liquid crystal lens array layers for light adjustment. Further, in another embodiment, the first floating image display device  14  can have different quantities of the first floating image display device  14  provided in different areas for light adjustment. In addition, the lens array layer  142  includes a first structure lens array layer (not shown in figures) and a second structure lens array layer (not shown in figures). The first structure lens array layer (not shown in figures) has a lens structure that can be used for modulating a light field, while the second structure lens array layer (not shown in figures) does not have a lens structure. 
     The first display module  141  can be a common flat-panel display. The first display module  141  has a display surface  1411  that can be used to display the image. The lens array layer  142  is disposed in proximity to the display surface  1411  of the first display module  141 . That is, the lens array layer  142  can be disposed above the first display module  141 . The lens array layer  142  can be in contact with or spaced apart from the display surface  1411  of the first display module  141 . An intermediate layer can also be provided between the display surface  1411  of the first display module  141  and the lens array layer  142 . 
     The first display module  141  can be arranged at a lowermost layer, which is responsible for displaying a flat image that has not yet undergone light reproduction. Such a flat image can be redistributed and recombined through the lens array of the lens array layer  142 , so as to be displayed as the three-dimensional image that is reorganized. The first display module  141  only needs to display a target image, so that the first display module  141  can be in any hardware configuration, such as that of a mobile phone, a tablet computer or a flat-panel display. A type and a configuration of the first display module  141  are not limited herein. The first display module  141  can also be a self-luminous display. 
     The lens array layer  142  can be arranged at an uppermost layer, and the lens array layer  142  has an effect of modulating the light field. The lens array layer  142  can adjust a light angle of a three-dimensional article, so that the original flat image that has yet to be reorganized can be redistributed and recombined, thereby allowing the viewer to view the three-dimensional image. 
     The lens array layer  142  is made of a material having a good optical property, and the material of the lens array layer  142  is not limited herein. The lens array layer  142  can include a substrate  1421  and a plurality of lenses  1422 . The plurality of lenses  1422  are disposed on a side of the substrate  1421 . That is, the plurality of lenses  1422  are disposed on the side of the substrate  1421  that is away from the display module  141 . An arrangement and a configuration of the lens array layer  142  are not limited. The plurality of lenses  1422  have a focusing function. The image that has yet to be reorganized (which is displayed on the display surface  1411 ) can be reorganized and recombined into an integrated image through the lens array layer  142 , so that the three-dimensional image is formed. 
     The first display module  141  can be any specification, as long as the algorithm can be applied thereto. That is, the first display module  141  includes an image calculation unit  1412 , and the image used in the first display module  141  needs to be calculated through an image algorithm. By cooperation with the configuration of the lens array, such a calculation predicts various traveling paths of light and calculates a relative position of the image. 
     The lens array layer  142  of the present disclosure is highly related to a display effect. As shown in  FIG. 14  the lens array can be arranged in a rectangular pattern, so that every two adjacent rows of the lens  1422  can be arranged in opposition to each other. As shown in  FIG. 15 , the lens array can also be arranged in a hexagonal pattern, so that every two adjacent rows of the lens  1422  can be arranged in a staggered manner. In addition, the plurality of lenses  1422  can also be arranged in other ways to display the three-dimensional image information. 
     The microstructure on the lens array layer  142  is a lens having the focusing function, and a focusing ability of the lens is determined according to a refractive index n value. Available light wavelengths of the lens range from  300  nm to 1100 nm. Focusing through the single lens is as shown in  FIG. 16 , which conforms to the lensmaker&#39;s equation of: 1/f=(n−1)(1/R1−1/R2). Here, R 1  and R 2  are correspondingly the radii of curvature on two side of the lens, f is the focal length of the lens and n is the refractive index of the lens. In addition, the lens having diameters ranging from 100 μm to 5 mm can be applicable to various display devices having various pixel sizes. In another embodiment, the microstructure of the lens array layer  142  can be an aspheric or thick lens whose optical properties are different from those described in the lensmaker&#39;s equation above, but the present disclosure is not limited thereto. In another embodiment, the lens array layer  142  can also exclude any microstructure. 
     Reference is made to  FIG. 17  to  FIG. 20 , in which  FIG. 17  is a schematic view of the floating image information of the first floating image display device or the second floating image display device when interacting with an object,  FIG. 18  is another schematic view of the floating image information of the first floating image display device or the second floating image display device when interacting with an object,  FIG. 19  is still another schematic view of the floating image information of the first floating image display device or the second floating image display device when interacting with an object, and  FIG. 20  is yet another schematic view of the floating image information of the first floating image display device or the second floating image display device when interacting with an object. 
     The user can interact with the first floating image information G 1 , the second floating image information G 2  or the integrated floating image information GIN by using a finger, an electronic interactive glove ECL or a pen-type interactive component PT. 
     That is, a sensor  149  of the first floating image display device  14  can be used to detect a coordinate value of a predetermined detection point of an object OB (i.e., a hand of the user), such as an index finger of the user, at least one predetermined coordinate value of the electronic interactive glove ECL, or a predetermined coordinate value of a pen tip of the pen-type interactive component PT. The sensor  149  continuously records a movement track of the predetermined detection point of the object OB within a predetermined time. The sensor  149  transmits a plurality of coordinate values of the movement track of the predetermined detection point of the object OB within the predetermined time to the controller  11 . The controller  11  determines an interaction status of the first floating image information G 1  according to the index finger of the user, the at least one predetermined coordinate value of the electronic interactive glove ECL, or the predetermined coordinate value of the pen tip of the pen-type interactive component PT. The sensor  149  is an image capturing unit. 
     Similarly, the second floating image information G 2  displayed through the second floating image display device  15 , and the integrated floating image information GIN cooperatively displayed through the first floating image display device  14  and the second floating image display device  15  can also be interacted with using the finger, the electronic interactive glove ECL or the pen-type interactive component PT, so that a subsequent display content of the image can be determined. 
     Furthermore, the user can also use the first floating image display device  14 , the second floating image display device  15 , and the first floating image display device  14  as well as the second floating image display device  15  to directly draw lines, planar compositions or three-dimensional compositions arranged in a space. 
     As shown in  FIG. 17  to  FIG. 20 , the user can draw a plurality of tracks PH 1  to PHN in a space on one side of the first floating image display device  14  by using the hand, the pen-type interactive component PT or the electronic interactive glove ECL. These tracks are then moved, adjusted or connected to generate the first floating image information G 1 . 
     In addition, the first floating image display device  14  can also include a program, which includes a plurality of function processing processes that correspond to a plurality of three-dimensional function buttons FBN. The plurality of three-dimensional function buttons FBN are displayed in the same space on the one side of the first floating image display device  14  as the first floating image information G 1  through the first display module  141 . 
     The user can select one of the plurality of three-dimensional function buttons FBN, such as coloring, enlarging, adjusting the material, etc., to process partial or all areas of the first floating image information G 1 . 
     That is, the user can selectively process flat areas, three-dimensional areas or all areas formed by the plurality of tracks. Similar to the previous embodiments, the first floating image information G 1  can be displayed in the space on the one side of the first floating image display device  14  in a form of an exploded view. 
     In addition, the first floating image display device  14  can communicate with the server through the controller  11  and the communication module  13 . The server can perform a calculation of a plurality of tracks of a large amount of first floating image information G 1 . In the present embodiment, the calculation of the two-dimensional image information and the three-dimensional image information can be performed by the first floating image display device  14  and the controller  11 , or can be carried out through cloud computing on the remote server. Then, the calculated two-dimensional image information or the calculated three-dimensional image information is transmitted to the controller  11 . 
     Beneficial Effects of the Embodiments 
     In conclusion, one of the beneficial effects of the present disclosure is that the floating three-dimensional image display system is capable of receiving the image information provided by the electronic device and converting the same to display the three-dimensional floating image information, so that a user experience can be expanded and the user can interact with the three-dimensional floating image information in real time.
