Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model aims at providing a with the help of the video device of window broadcast, through attached automatically controlled membrane of adjusting luminance on the transparent glass of window, cooperation projection equipment to solve the unable make full use of current large-scale window and carry out the problem of video broadcast.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
Example 1:
this embodiment provides a device with the help of window broadcast video, as shown in fig. 1 and 2, including window 1, be equipped with transparent glass 11 on the window 1, 11 surface posts of glass have automatically controlled membrane of adjusting luminance 2, 2 external power supplies of automatically controlled membrane of adjusting luminance, the opposite of window still is equipped with external power supply's projection equipment 3, the image that projection equipment 3 put in falls into glass's region completely, projection equipment 3 and the linkage of automatically controlled membrane of adjusting luminance 2, when the circular telegram of automatically controlled membrane of adjusting luminance 2, automatically controlled membrane of adjusting luminance 2 is transparent state, 3 outage of projection equipment this moment, do not play projection video, when the power failure of automatically controlled membrane of adjusting luminance 2, automatically controlled membrane of adjusting luminance 2 is non-transparent vaporific, 3 circular telegrams of projection equipment this moment, window 1 just can act as projection.
Specifically, the electrically controlled dimming film 2 is a PDLC film, which is formed by mixing low molecular liquid crystal and a prepolymer, performing a polymerization reaction under a certain condition to form micron-sized liquid crystal droplets uniformly dispersed in a polymer network, and obtaining a material having an electro-optical response characteristic by using dielectric anisotropy of liquid crystal molecules, wherein the material mainly works between a scattering state and a transparent state and has a certain gray scale, and when the material is powered on, the material is in a transparent state, and when the material is powered off, the material is in a mist state.
Further, automatically controlled membrane 2 of adjusting luminance is through the control break-make of infrared induction switch 4, infrared induction switch 4 sets up in 1 non-projection one side of window, like this when someone is through the window, infrared induction switch 4 just can obtain the response and put through, the circular telegram of the automatically controlled membrane 2 of adjusting luminance of control, automatically controlled membrane 2 of adjusting luminance is the transparent state this moment, the people can see through glass and see the offside condition, when nobody passes through, infrared induction switch 4 is in the off-state all the time, automatically controlled membrane 2 of adjusting luminance is not circular telegram, it is vaporific, projecting apparatus 3 carries out the projection on window 1 this moment, the broadcast video, the advertisement in places such as specially adapted store like this, the broadcast of promo piece.
In the embodiment, when the device for playing video by means of a window is used, firstly, the electronic control dimming film 2 is attached to the window 1 needing to play video, the electronic control dimming film 2 is connected with electricity and is connected with the infrared induction switch 4 to control on-off, meanwhile, the electronic control dimming film 2 is linked with the projection equipment 3, when the electronic control dimming film 2 is powered on, the projection equipment 3 is powered off, when the electronic control dimming film 2 is powered off, the infrared induction switch 4 is arranged on one side of the window 1, the projection equipment 3 is well adjusted, and a projected picture can completely fall on the window 1, so that when a person passes through the window, the infrared induction switch 4 can obtain induction and is connected, the electronic control dimming film 2 is controlled to be powered on, at the moment, the electronic control dimming film 2 is in a transparent state, the person can see the opposite side condition through glass, when no person passes through the window, the infrared induction switch 4 is always in an off state, the electric control dimming film 2 is not electrified and is in a fog shape, and the projection equipment 3 projects on the window 1 to play videos.
The utility model discloses the principle and the implementation mode of the utility model are explained by applying the concrete examples, and the explanation of the above examples is only used for helping to understand the method and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present description should not be construed as a limitation of the present invention.
