Detailed Description

In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the technical solution of the present invention will be further explained by combining the drawings and by means of the specific implementation manner.

The following describes a specific structure of a curtain double-sided display device according to an embodiment of the present invention with reference to fig. 1.

As shown in fig. 1, the utility model discloses two-sided display device of (window) curtain includes display screen 1 and winding mechanism 2, and display screen 1 includes stratum lucidum 11 and dull polish layer 12, and dull polish layer 12 is attached to on stratum lucidum 11, and dull polish layer 12 can reflect simultaneously and transmission light is in order to realize two-sided display pattern, and winding mechanism 2 links to each other with the side of display screen 1 to realize the rolling of display screen 1 and unreel.

It is understood that, in the present embodiment, since the frosted layer 12 is provided to reflect and project light simultaneously, when the projector projects a pattern onto the double-sided display screen 1, the pattern may exist on both sides of the frosted layer 12, thereby realizing double-sided display. In addition, due to the existence of the rolling mechanism 2, the display screen 1 can be rolled up when not in use, so that the floor area of the curtain double-sided display device when not in use is reduced, and the display screen 1 can be well protected.

It should be additionally noted that the frosted layer 12 may be formed by curing a display liquid for displaying pictures and films uniformly coated on the transparent layer 11, or may be formed by adhering a light material capable of reflecting light and projecting light to the transparent layer 11 through a glue layer. Furthermore, the utility model discloses a two-sided display device of (window) curtain can shelter from sunshine as the (window) curtain by daytime illumination stronger, and can regard as trade company's bill-board under the comparatively dark environment evening. Therefore, the practicability of the curtain double-sided display device is better.

In some embodiments, the frosting layer 12 has a light transmittance of 40% -60%. It will be appreciated that too much light transmittance of the frosting layer 12 may obscure the pattern on the side of the frosting layer 12 facing the projection device, and that too little light transmittance of the frosting layer 12 may obscure the pattern on the side of the frosting layer 12 facing away from the projection device. The light transmittance of the frosted layer 12 is controlled to be 40% -60%, and the clear projection patterns on the two surfaces of the frosted surface can be ensured.

In some embodiments, the refractive index of sanding layer 12 is between 40% and 60%. It will be appreciated that an excessively large refractive index of frosting layer 12 may obscure the pattern on the side of frosting layer 12 facing away from the projection apparatus, and an excessively small refractive index of frosting layer 12 may obscure the pattern on the side of frosting layer 12 facing the projection apparatus. The refractive index of the frosted layer 12 is controlled to be 40% -60%, and the fact that the projection patterns on the two surfaces of the frosted surface are clear can be guaranteed. Of course, the refractive index and light transmittance of the frosted layer 12 are not limited to the above ranges, and the refractive index and light transmittance of the frosted layer 12 may be selected according to actual conditions.

In some embodiments, the transparent layer 11 is a transparent plastic layer. Therefore, the transparent layer 11 can protect the frosted layer 12 and does not affect the pattern. Of course, in other embodiments of the present invention, the transparent layer 11 may be another flexible material layer.

In some embodiments, the edge of the frosted layer 12 is located inside the edge of the transparent layer 11, and the edge of the frosted layer 12 is spaced from the edge of the transparent layer 11 by 10mm to 20 mm. It can be understood that, in the actual use process, the display screen 1 needs to be hung up, the lower end of the display screen 1 may hang down, and the edge of the frosted layer 12 is located inside the edge of the transparent layer 11, so that the edge of the frosted layer 12 can be protected, and the service life of the display screen 1 is prolonged. Of course, in other embodiments of the present invention, the distance between the edge of the frosted layer 12 and the edge of the transparent layer 11 is not limited to the above range, and the distance between the edge of the frosted layer 12 and the edge of the transparent layer 11 can also be selected according to actual conditions.

In some embodiments, the winding mechanism 2 includes a driving member and a winding member, and the driving member can drive the winding member to rotate to wind and unwind the display screen 1. From this, automatic rolling and unreeling can be realized to display screen 1, have improved customer and have used the satisfaction. Of course, in the other embodiments of the present invention, the winding mechanism 2 can be a manual mechanism, and the user manually winds and unwinds the display screen 1. In addition, in the present invention, the driving member may be a rotating electrical machine or may be other driving structures, and the specific type of the driving member is not limited herein.

In some embodiments, the transparent layer 11 has a thickness of 0.2mm to 0.5 mm. It will be appreciated that too little thickness of the transparent layer 11 will make the transparent layer 11 more susceptible to breakage, and that too much thickness of the transparent layer 11 will increase the cost and weight of the display screen 1. The thickness of the transparent layer 11 is controlled to be 0.2mm-0.5mm, which not only ensures the strength of the transparent layer 11 and reduces the damage rate of the transparent layer 11, but also controls the cost and weight of the display screen 1. Of course, the thickness of the transparent layer 11 in other embodiments of the present invention may be selected according to practical situations, and is not limited to the above range.

In some embodiments, the sanding layer 12 has a thickness of 0.2mm to 0.5 mm. It will be appreciated that an excessively small thickness of the frosted layer 12 makes the frosted layer 12 more susceptible to breakage, and an excessively large thickness of the frosted layer 12 increases the cost and weight of the display screen 1. The thickness of the frosted layer 12 is controlled to be 0.2mm-0.5mm, so that the strength of the frosted layer 12 can be ensured, the damage rate of the frosted layer 12 is reduced, and the cost and the weight of the display screen 1 can be controlled. Of course, the thickness of the frosted layer 12 in other embodiments of the present invention may be selected according to practical situations, and is not limited to the above range.
