Embodiment Construction

[0032] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0033] Such as Figure 1 to Figure 2 As shown, the embodiment of the present invention proposes a composite film, including a scattering polarizing layer 1 and an absorbing polarizing layer 2 bonded to the scattering polarizing layer 1. The scattering polarizing layer 1 includes a first triacetate film layer 11, The polyvinyl alcohol doped liquid crystal film layer 12 and the second cellulose triacetate film layer 13 .

[0034] The composite film provided by the above technical solution, when the light is incident, because the scattering polarizing layer 1 has a light transmission axis, half of the light is transmitted and half of the light is scattered; The composite film formed by compounding the scattering polarizing layer 1 has an asymmetrical visual effect. Viewed from the side of the scattering polarizing layer 1, it is a colorless translucent co...

Abstract

The present invention discloses a composite pasting membrane and a manufacturing method. The composite pasting membrane comprises a scattering polarization layer and an absorption polarization layer attached to the scattering polarization layer, and the scattering polarization layer comprises a first triacetate film layer, a polyethylene alcohol doped liquid crystal membrane layer and a second triacetate membrane layer which are laminated orderly. The present invention also provides an unsymmetrical perspective glass comprising a glass pane unit and the above composite pasting membrane, and the scattering polarization layer is arranged between the absorption polarization layer and the glass pane unit. In addition, the present invention also provides a transparent rear projection screen comprising the above composite pasting membrane. The composite pasting membrane of the present invention has an unsymmetrical visual effect, can be applied to the building indoor partition decoration and transparent rear projection screen fields.

Description

technical field [0001] The invention relates to the technical field of optical functional films, in particular to a composite film, a manufacturing method, an asymmetric see-through glass and a transparent rear projection screen. Background technique [0002] At present, the glass used in indoor partitions usually has the same visual effect when viewed from both sides of the glass. As people's requirements for living and working environments are getting higher and higher, this kind of glass has been difficult to meet people's needs. The existing one-way see-through glass is a half-mirror coating technology, and the application occasion is an environment where there are two rooms, one bright and one dark, and it is suitable for special occasions such as the interrogation room of the Public Security Bureau. In addition, the transparent projection screen not only enables the audience to see the scene behind the screen, but also enables the audience to see the image on the scree...
