Specifically, in the curtain provided by the embodiment of the application, in order to eliminate the shadow left on the green curtain or the blue curtain by the shooting object or other facilities, a reflective layer is arranged on the back of the green curtain or the blue curtain.

It will be appreciated that the light-reflecting layer may comprise a substrate 11 and a reflective layer 12 in order to enable incident light incident on the light-reflecting layer to be re-incident on the front surface of the curtain.

The substrate may include a substrate 111 and a light shielding layer 112, and the substrate may be a substrate for supporting, such as made of flexible polyethylene, etc., so as to facilitate storage and carrying of the curtain; the light shielding layer may be formed by applying ink or the like.

The light shielding layer is arranged on one side far away from the front side of the curtain, so that the reflecting layer is positioned between the light shielding layer and the filter layer, the incident light incident to the reflecting layer can be prevented from being transmitted to the back side of the curtain by the light shielding layer, light loss is caused, namely, the light transmitted through the curtain is reflected to the front side of the curtain again by the emitting layer, and the brightness of the front side of the curtain is improved. And then the reflected light is filtered by utilizing the green curtain or the blue curtain serving as the filter layer, so that the uniform green or blue matting background is presented on the surface of the curtain.

It can be understood that in the use of carrying out infant teaching, when shooing the formation video information to the infant promptly, be provided with the light filling lamp in order to improve the luminance of shooing the environment in the shooting environment. If the device is used for indoor shooting, the illuminating lamp can be used as a light supplement lamp; or in an outdoor environment, a dimming lamp group for increasing light can be additionally arranged, such as a plurality of LED lamps arranged at the edge of the curtain.

It can also be understood that the dimming lamp group can be controlled by the server, the single chip microcomputer and other control modules to adjust the brightness of the effective coverage range of the curtain in real time according to the current shooting effect, so that the shooting environment is in the best brightness.

When the dimming lamp bank or the illuminating lamp is used as a light supplementing lamp to adjust the brightness of a shooting environment, light output by the dimming lamp bank or the illuminating lamp can be incident to the front side of the curtain, then is incident to the reflecting layer through the curtain, and is incident to the shooting environment through the curtain after being reflected on the reflecting layer in the reflecting layer, so that the brightness of the surface of the whole curtain can be enhanced, and shadows left on the curtain by shooting objects or other facilities are eliminated.

Further, as shown in fig. 4, in order to make the incident light to the back of the curtain, after being reflected by the reflective layer, the light incident to the front of the curtain again can form diffuse reflection at a plurality of angles, so as to avoid forming local strong light, and a texture structure can be formed on the surface of the blue curtain or the green curtain serving as the filter layer 2, for example, the curtain serves as a non-woven fabric, and criss-cross textures are formed on the surface of the curtain, so that the enhanced light distribution incident to the surface of the curtain is more uniform.

Preferably, in combination with fig. 2, in the curtain provided in the embodiment of the present application, the reflective layer 12 may include a carrier 121 and a first particle layer 122 disposed in the carrier.

Specifically, in order to increase the reflection effect, a layer of carrier may be adhered to the substrate, and microparticles of a plurality of reflection surfaces, that is, the first microparticle layer, may be uniformly blended in the carrier. Such as by coating an adhesive on the substrate and then uniformly blending silica particles into the adhesive to form the reflective layer 12.

Preferably, as shown in fig. 3, in the curtain of the embodiment of the present application, in order to further enhance the intensity of the reflected light reflected to the surface of the curtain, an enhancement layer 3 may be further disposed between the light reflecting layer 1 and the filter layer 2, that is, the enhancement layer 3 is disposed between the curtain and the first particle layer of the light reflecting layer.

Specifically, the reinforcing layer may include an adhesive matrix 31 and a second particle layer 32 adhered to the adhesive matrix. The reflected light can be incident to the enhancement layer after being emitted from the reflective layer, and the incident light is further enhanced and diffused by the second particle layer 32 on the enhancement layer to increase the angle of the incident light incident to the filter layer, so that the incident light can be uniformly incident to the curtain serving as the filter layer after being enhanced by the enhancement layer. The second particulate layer may be nanoparticles, such as nano-titanium particles, of different sizes.

Further, with reference to fig. 4, in order to increase the refractive index of the incident light incident on the enhancement layer 3, a light control layer 4 is further disposed between the reflective layer 1 and the enhancement layer 3, and the refractive index of the light control layer is smaller than that of the reflective layer.

Optionally, in the curtain provided in this embodiment of the present application, the light control layer may be a photosensitive colloid 41.

Further, in the curtain provided in the embodiment of the present application, the light control layer may further include a light-condensing layer 42, and the light-condensing layer 42 may be disposed on the photosensitive colloid.

For example, in one embodiment, the light management layer may include a photosensitive gel and a triangular prism array 42 disposed on the photosensitive gel.

It can be understood that the triangular prism array is evenly arranged on the photosensitive colloid, so that the triangular prism array is close to one side of the curtain, the ground of the triangular prisms in the triangular prism array is close to the light colloid, and one edge is close to the curtain.

In summary, under the scene of the preschool education for the infant, the dimming lamp group is arranged at the edge of the curtain provided by the embodiment of the application, and the dimming lamp group can be a lamp group formed by combining a plurality of LED lamps. The dimming lamp group is used for adjusting the brightness of the curtain, and can provide light for the edge and the effective coverage range of the curtain when the dimming lamp group is in an opening state. This light incides the curtain surface as the incident light, then behind the blue curtain or the green curtain as the filter layer, can be reflected by the reflector layer at filter layer back to make a plurality of reverberation incide the effective coverage area of curtain again from a plurality of angles, from having formed the diffuse reflection on the curtain surface, eliminated and caught the shadow that the object and other settings caused, improved the definition of shooting, and then improved the keying effect, realized the smooth synthesis of virtual display scene.

The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be appreciated by persons skilled in the art that the scope of the application referred to in the present application is not limited to the particular combination of features described above, but also covers other arrangements formed by any combination of the above features or their equivalents without departing from the spirit of the application.
