In order to have a further understanding and understanding of the characteristics and effects of the application, only examples and detailed descriptions are used, and the description is as follows:

Please refer to FIG. 1, which is a circuit block diagram of the first embodiment of the present application. The fixed focus three-dimensional imaging display system is suitable for an imaging space. The display system includes a storage module 11, a holographic image projection module 12, and a processing module 14. The processing module 14 is electrically connected to the storage module 11 and Holographic image projection module 12. The storage module 11 stores plural pieces of object information 112, and the holographic image projection module 12 includes an X-axis light projection component 122, a Y-axis light projection component 124, and a Z-axis light projection component 126, and the X-axis light projection components 122, Y The axis light projection component 124 and the Z axis light projection component 126 are respectively disposed in the imaging space, that is to say, the X axis light projection component 122, the Y axis light projection component 124, and the Z axis light projection component 126 are respectively disposed at the X position in the space, Y position and Z position. The processing module 14 controls the X-axis light projection component, the Y-axis light projection component and the Z-axis light projection component to respectively project a directional projection light to excite an imaging medium in a three-dimensional imaging area for display according to one of the object information A holographic projection image. The imaging medium can be air. When the directional projection light in the three X-axis directions of X, Y, and Z is focused, the light generated by the excited state at the focusing position in the three-dimensional imaging area can cause the air molecules to generate light to achieve display. It is the three-dimensional imaging of specific points in the air, which shows the holographic projection image. The object information 112 may be static object information or dynamic object information. When the processing module 14 outputs static object information, the X-axis light projection component, the Y-axis light projection component, and the Z-axis light projection component are controlled to project directivity, respectively. The projection light excites the imaging medium in a three-dimensional imaging area to display a holographic projection image of static object information; similarly, when the processing module 14 outputs dynamic object information, the X-axis light projection component, the Y-axis light projection component and the The Z-axis light projection components respectively project directional projection light to excite the imaging medium in a three-dimensional imaging area to display holographic projection images of dynamic object information. Therefore, holographic projection images can be displayed through simple X, Y, and Z three-axis projection equipment.

In order to achieve the ability to control the holographic projection image in addition to the naked-view 3D, and to increase the flexibility of the interactive operation, please refer to FIG. 2, which is a circuit block diagram of the second embodiment of the present application. The components and operation modes in this second embodiment are the same as those in the first embodiment, so they will not be repeated here, and the differences will be explained. The display system includes a display 10, which includes a plurality of detectors 102, a control circuit 104, and a sensing area 106. The display 10 is a touch display or an electrochromic display, and the control circuit 104 is electrically connected to the detectors 102. The detectors 102 are disposed in the sensing area 106 to sense a gesture. The control circuit 104 generates a gesture signal according to the gestures detected by the detectors 102. The detectors 102 are infrared detectors, light detectors or thermal image detectors. Taking the infrared detector as an example, infrared light can be divided into three parts. The wavelength of near infrared rays is between 0.75 and 1.5 μm, the wavelength of mid-infrared rays is between 1.5 and 6 μm, and the wavelength of far infrared rays is between 6 and 1000 μm. When the hand is close to the sensing area, the infrared rays emitted by these infrared detectors reflect the detection signal back to the control circuit 104 due to the hand blocking, that is, the control circuit 104 can be operated according to the hand gesture to generate the gesture signal. Taking the thermal image detector as an example again, when the hand is close to the sensing area 106, the thermal image detector emits infrared light to control the hand to perform photosensitive imaging, and feeds back the detection signal to the control circuit 104. The control circuit 104 According to the gesture control, for example, the different temperature colors and corresponding coordinate positions presented on the thermal image by the photosensitive imaging are used to generate the gesture signal. Taking the light detector as an example, when the hand is close to the sensing area 106, the hand gestures are operated. These light detectors detect gestures in the sensing area 106 to capture images at various time points and control The circuit 104 determines the movement of the limb and generates a gesture signal through calculation by a related algorithm. Whether the above gesture control is detected by using an infrared detector, a light detector or a thermal image detector, it can reflect the effect of the gesture signal generated by the volley control.

The processing module 14 obtains one of the object information 112 according to the gesture signal and the gesture signal, and controls the X-axis light projection component 122, the Y-axis light projection component 124, and the Z-axis light projection component 126 to project directional projection light, respectively The imaging medium, such as air, in the three-dimensional imaging area is excited to display the holographic projection image of the corresponding object information 112 accordingly. In detail, when the hand performs volley control on the sensing area 106 of the display 10, the detectors 102 sense a gesture in the sensing area, and the control circuit 104 generates a gesture signal according to the gestures detected by the detectors The gesture signal can be a dynamic signal that controls the movement or rotation of the object information 112. At this time, the processing module 14 can obtain the corresponding object information 112 according to the gesture signal, that is, the object information 112 in the display 10 can be pulled according to the gesture signal Out of the display, the processing module 14 correspondingly controls the X-axis light projection component 122, the Y-axis light projection component 124 and the Z-axis light projection component 126 to project the directional projection light to excite the imaging medium in the three-dimensional imaging area according to the gesture signal. In order to display the holographic projection image of the corresponding object information 112, the holographic projection image is a real three-dimensional image that can reproduce the object. The combination of the volley control technology and the holographic image projection module 12 can accurately detect the gesture in the stereo imaging The position and the moving direction in the space, thereby realizing the effect that the 3D image can be pulled out from the display 10 and present the holographic projection image.

When the directional projection light system projected by the X-axis light projection component 122, the Y-axis light projection component 124, and the Z-axis light projection component 126 is parallel projection light, the X-axis light projection component, the Y-axis light projection component, and the Z axis A light interference element (not shown in the figure) is respectively arranged at the corresponding position of the light projection component. The light interference element is a projector or a light projector. Since the X-axis, Y-axis, and Z-axis three-axis imaging will leak light and cause image retention in the rear, destructive interference is generated in the three-dimensional imaging area using the optical interference element to eliminate the X-axis light projection component 122 and the Y-axis light projection component 124 and the Z-axis light projection component 126 project the residual image generated in the three-dimensional imaging area, and then completely present the holographic projection image. The holographic image projection module further includes a plurality of light detectors (not shown in the figure), which are respectively disposed on one side of each light interference element. These light detectors are used to detect the obstruction in the three-dimensional imaging area, for example The position covered by the hand will be described in detail later as to how to fill light for the covering.
