[0022] Preferred embodiments of the present disclosure will now be described in more detail. While preferred embodiments of the present disclosure are described below, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0023] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in its normal operating state, while "inner" and "outer" refer to their position relative to the device's outline. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Since the accompanying drawings describe the same device, the same reference numerals denote the same components.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This disclosure provides an interactive transparent display system, including:

[0026] A transparent screen, the transparency of which is variable;

[0027] A projection system includes a projector mounted on a lifting frame for projecting onto a transparent screen. The lifting frame is mounted on a building and the position of the projector is adjusted by lifting.

[0028] A control system, which is connected to the transparent screen and the projection system, is used to adjust the parameters of the transparent screen and the projection system;

[0029] The transparent screen is equipped with a radar and a laser scanner at its top; the radar, laser scanner, and camera are used to scan and acquire environmental and object information in real time.

[0030] Specifically, refer to Figure 1 This disclosure provides an interactive transparent display system, including a transparent screen 110, a projection system 120, and a control system 130. The transparent screen is connected to a central control system, which can be installed on a building wall. The central control system includes a switch button connected to the transparent screen, and the transparent display screen is turned on by the switch button in the central control system. In some embodiments, the switch button is installed on the wall, near a light switch, and at a distance from the transparent screen.

[0031] In operation, the transparent screen is activated. Upon activation, the projection system's lifting frame is powered on and descends from the roof. Simultaneously, the projector is turned on, projecting the image onto the transparent screen. The transparent screen is used to display the projected image. In one embodiment of this invention, the transparent screen is made of a dimming film, an electronically controlled light-reducing thin-film material made using PDLC (polymer dispersed liquid crystal) technology. Its core characteristic is that it is transparent when powered on and becomes a translucent but opaque mist when powered off, thus combining privacy protection and light adjustment functions. In this invention, its opacity is adjusted by controlling the power supply voltage, thereby displaying the image projected by the projector.

[0032] like Figure 2 As shown, in some embodiments, the transparent screen includes a projection medium layer 1103 and two glass bodies 1101 and 1102. The projection medium layer 1103 is disposed between the two glass bodies. Furthermore, a touch layer 1104 may also be disposed within the transparent screen, supporting user touch interaction. The touch screen may be, for example, a capacitive screen. During use, non-contact interaction can be achieved by the user lightly touching the transparent screen with their finger, or by the radar or camera at the top of the transparent screen recognizing the user's gestures. LED lights may also be provided on the transparent screen to adjust its brightness.

[0033] In some embodiments, a radar 1106, a laser scanner 1107, and a camera 1108 are provided on the top of the transparent screen. The radar, laser scanner, and camera are used to acquire various information about the surrounding environment, people, and objects in real time, and adjust the display parameters of the transparent screen according to the acquired information. Specifically, based on the environmental and object information acquired by the laser scanner, the transparency of the transparent screen can be automatically adjusted according to the surrounding environmental conditions such as lighting and the number of viewers, so as to adapt to the environmental conditions and ensure the best visual effect.

[0034] In some embodiments, the interactive transparent screen is also connected to a computing unit, which can directly process local data and reduce the cloud computing burden. The computing unit is, for example, a computing chip integrated into the central control system, which is connected to the control system through a high-speed data interface.

[0035] In some embodiments, the lifting frame is fixed to the roof or wall, and the height and angle of the projector are adjusted by lifting or rotating to ensure that the projected image matches the size and position of the transparent screen. Specifically, in one embodiment of this application, the lifting frame is connected to the ceiling. When the projector needs to work, the lifting frame descends to transport the projector from a hidden location in the ceiling. When the projector is turned off, the lifting frame retracts, "hiding" the projector back into the ceiling. In one embodiment of this application, the distance between the lifting frame and the transparent screen is fixed at 2.5 meters, meaning that the distance between the projector and the transparent screen is fixed at 2.5 meters when the projector is working.

[0036] In some embodiments, the distance between the projector and the transparent screen during operation can be 1-10 meters. In different embodiments, the distance between the projector and the transparent screen can be set according to the parameters of different projectors and other components to ensure that the projected image is clear and undistorted. This application does not impose any limitations on this.

[0037] In some embodiments, the projector is provided with an ultra-short-throw lens 1109 on its upper part, and the ultra-short-throw lens is used as the projector to ensure high-quality projection at short distances.

[0038] In some embodiments, the transparent screen and the projector are both connected to the control system, enabling centralized control and adjustment.

[0039] In one embodiment of this application, the control system is connected to an external central control system and is used to adjust the parameters of the transparent screen and the projection system. Specifically, the parameters of the transparent screen include the screen area size and transparency, and the parameters of the projection system include the brightness, contrast ratio, and focal length of the ultra-short-throw lens of the projector.

[0040] In some embodiments, the brightness range of the transparent screen is 300-1500 nits, and the load-bearing range of the lifting frame is 0-50 kg.

[0041] In some embodiments, the transparency of the transparent screen can be 20%~95%, and the touch response time is ≤10ms; the projector has a resolution of 4K, a brightness of ≥5000 lumens, and a projection ratio of 0.25:1 for the ultra-short throw lens; the adjustment range of the lifting frame is 1-10 meters, and the load-bearing capacity of the lifting frame is ≥20kg; the control system is equipped with HDMI, USB, and Wi-Fi communication interfaces, supporting integration with mainstream central control systems.

[0042] In one embodiment of this application, the transparent screen is specifically 85 inches in size, with a transparency of 90%, a brightness of 1500 nits, a touch response time of 5ms, and a built-in radar module supporting gesture recognition at a distance of 0.5-3 meters. In the projection system, the projector has a resolution of 4K (3840×2160), a brightness of 6000 lumens, a throw ratio of 0.25:1 for the ultra-short throw lens, and an adjustment range of 3-8 meters for the lifting platform, the adjustment range of which is adjusted according to the ceiling height of the exhibition center.

[0043] During use, the control system automatically adjusts the projector's brightness, focus, and the height of the lifting platform based on the size and position of the transparent screen, ensuring that the projected image matches the transparent screen and adapts to different scenario requirements. Next, the projector can project information such as global weather data, meteorological cloud maps, and climate change trends onto the transparent screen, and adjust display parameters such as the transparent screen's transparency according to the surrounding environment.

[0044] In some embodiments, the control system can dynamically adjust parameters such as the opacity of the transparent screen and the brightness of the projector according to the ambient light and usage scenario of the exhibition center, etc., to ensure the best display effect.

[0045] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, such as the combination of technical features between embodiments, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
