Problems solved by technology

[0004] With the improvement of people's needs, people have put forward higher requirements for one-way see-through products, not only requiring them to have a one-way see-through function, but also hoping that their light transmittance can be adjusted. In the prior art, no matter whether it is a privacy film or a One-way perspective glass, its light transmittance is fixed and cannot be adjusted and controlled

[0049] figure 1 It is a structural schematic diagram of the see-through device according to the first embodiment of the present invention. The see-through device has a side facing the observer and a side facing the person being observed. The one-way see-through layer 10 has a first face 11 towards the observed side and a second face 12 towards the observed side, and the one-way see-through direction of the one-way see-through layer 10 is from the observed side towards the observer One side (that is, from the first surface 11 to the second surface 12). In this embodiment, the liquid crystal control layer includes a first liquid crystal control layer 20 . The first liquid crystal adjusting layer 20 is stacked with the one-way see-through layer 10 , and the first liquid crystal adjusting layer 20 is set on the side of the one-way see-through layer 10 facing the observed person. In other embodiments, the first liquid crystal regulating layer 20 may also be disposed on the side ...

[0056] image 3 It is a structural schematic diagram of the see-through device according to the second embodiment of the present invention. Different from the first embodiment, in this embodiment, if image 3 As shown, the first liquid crystal adjustment layer 20 has a first adjustment area 24 and a first blank area 25, and the liquid crystal molecules are arranged in the first adjustment area. The one-way see-through layer 10 has a first see-through area 14 and a second see-through area 15 . The first see-through area 14 has a one-way see-through function from the observed side to the observer's side, and the second see-through area 15 has a one-way see-through function from the observer's side to the observed side. In this embodiment, there is an overlapping area between the first adjustment area 24 and the first see-through area 14 , and an overlapping area between the first blank area 25 and the second see-through area 15 .

[0067] Image 6 It is a structural schematic diagram of the see-through device according to the third embodiment of the present invention. Different from the second embodiment, in this embodiment, the see-through device may also include a second liquid crystal adjusting layer 30, and the second liquid crystal adjusting layer 30, the one-way see-through layer 10 and the first liquid crystal adjusting layer 20 are laminated set up. In this embodiment, the second liquid crystal adjustment layer 30 and the first liquid crystal adjustment layer 20 are respectively disposed on opposite sides of the one-way perspective layer 10 .

[0068] In the see-through device of this embodiment, the second liquid crystal adjustment layer 30 can be used to assist in adjusting the light transmittance of the see-through device from the observed side to the observer's side to obtain better brightness adjustment. At the same time, the second liquid crystal adjustment layer 30 can also be used to ad...

Abstract

The invention discloses a see-through device, which relates to the technical field of liquid crystal application. The see-through device includes a one-way see-through layer with one-way see-through function, and also includes a liquid crystal control layer for adjusting light transmittance, the liquid crystal control layer and the one-way see-through layer are laminated. Since the see-through device includes a one-way see-through layer with a one-way see-through function, it has a one-way see-through function, and the light transmittance of the see-through device can be adjusted through the liquid crystal control layer, thereby adjusting the brightness of the light received by the observer, It satisfies people's demand for adjustable brightness of the one-way perspective device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal applications, in particular to a see-through device. Background technique [0002] In order to meet people's privacy needs, a layer of privacy film is usually pasted on the side windows of the vehicle. privacy within. [0003] In scenarios such as public security bureaus and detention centers, one-way perspective glass is usually used. One-way perspective glass is divided into front and back. The front is a glass mirror to reflect light. When in use, the front side faces the monitored room, and the reverse side faces the monitoring room, which is where the judge is. When the light intensity of the monitored room is greater than that of the monitoring room, the personnel in the monitored room cannot see the situation of the monitoring room, but Personnel can always see the status of the monitored room. The realization principle of the one-way perspective glass is that the reverse surfac...
