The touch transparent projection film is applied to the release of the subway advertisement space by the advantage that the touch transparent projection film is free of shielding. As shown in fig. 2, the display 11 is located on the upper half of the window glass 10 and does not obstruct the view of the passenger, as seen from the front view 2A. As can be seen from fig. 2B, the touch transparent projection film 15 is directly attached to the transparent medium 12, and when light is emitted from the projector 13 onto the touch transparent projection film 15, the light is reflected on the touch transparent projection film 15, and the reflected light 14 is captured by human eyes of the observer 16, so that an image can be observed.
The touch control function can be started by connecting the computer host with the touch control layer. The touch layer selected here is provided by Jiangsu force cloud technology, Inc., but not limited thereto, the touch layer itself does not interfere with the projection. Compared with the traditional method of selecting and controlling images by using a remote controller, the touch layer can directly realize interaction with projection through touch, such as image switching, touch drawing, APP program operation and the like, can perform multi-finger operation, and has certain novelty. As shown in fig. 3, when the computer host 18 is connected to the touch transparent projection film 15 and the projector 13 plays a picture, the observer 16 can touch the touch transparent projection film 15 with a finger, and the touch transparent projection film 15 transmits a signal to the computer host 18 through the transmission line 17 after receiving information, and finally reflects the signal to the projection picture to implement an interactive function.
The embodiment can also provide a plurality of control modes, including but not limited to direct touch control on the surface of the membrane, remote control through an infrared controller, and accurate operation by using a Bluetooth peripheral or a USB direct-connected device, such as a mouse and a keyboard. And the control mode can be flexibly switched according to different application scenes.
The touch transparent projection films can be mutually spliced, the size can be freely selected according to the angle and the distance of the projector, the touch transparent projection films can be flexibly used in markets and supermarkets needing large-size projection, meanwhile, the cost of the film is lower than that of the film in transparent OLED and LED display screens, and the investment can be greatly reduced in maintenance and replacement.
Example 2
The example provides a touch transparent projection system, which comprises a transparent projection screen and an ultra-short focus projector positioned on one side of a matching layer in the transparent projection screen. For vehicles such as automobiles and subways, the space is often limited. The traditional projector projection ratio can not meet the requirement, or as the distance between the projector and the picture is large, passing pedestrians can appear between the projector and the picture, so that a part of the picture is blocked, and the customer experience is influenced. The ultra-short-focus projector of the embodiment can be used for shortening the distance between the ultra-short-focus projector and the transparent projection film, so that the space is saved, and the loss of pictures can not be caused while passengers are not influenced.
The traditional transparent projection film cannot be well matched with the ultra-short-focus projector, because the angle of light emitted by the ultra-short-focus projector is large, when the light is reflected on the projection film, a large part of light is reflected towards a large visual angle and cannot enter human eyes, and the uneven picture and the loss of brightness are caused. The random microstructure of the traditional transparent projection film is changed into a structure with a regular geometric shape, and light is straightened, so that uniform imaging of a picture and full utilization of the light are realized, and the technology can greatly improve the space problem and the customer experience.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
