Manufacturing method for rear screen set

The rear projection screen set method is disclosed. Rear projection screen set production method in accordance with one embodiment, after a first transparent uniformly coat the polymer dispersed liquid crystal on the conductive film to form the liquid crystal membrane with a polymer dispersion and, laminating the second transparent conductive film on the polymer dispersed liquid crystal complex film , to curing treatment with ultraviolet rays steps to create a polymer dispersed liquid crystal display element; The method comprising for each electrical terminal operation on the first transparent conductive film and the second transparent conductive film; Depositing a first bonding film on the first transparent conductive film, and laminating the second adhesive film on the second transparent conductive film; The step of sequentially laminating a UV-blocking film and the third film bonded on the first adhesive film; After laminating the first glass above the third bonding film, and laminating a second glass on the second bonding film to the lamination step to create a smart glass; And the interior of the frame the end beam projector ultrashort the bottom of the back up or back side of the smart glass to place the smart glass on the front of the frame, and an effort on the second glass so that the sunlight which the first glass is arranged on the incoming direction rear projection screen set disposed (rear screen set) the comprising the steps of creating the first transparent conductive film of the transparent conductive thin film and the second transparent conductive thin film of a conductive oxide includes at least one of the transparent conductive film is an indium -tin-oxide (ITO) or zinc-containing oxide (ZnO) and the zinc-oxide (ZnO), the aluminum (Al), gallium (Ga), indium selected from the group consisting of (in) and boron (B) substance is 2 to 15 is doped in an amount of by weight%, of the first glass and the second glass contains at least one high refractive index oxide with a low refractive material it is alternately applied 4 times or more Ting is, the lamination is for 10 to 20 minutes at ambient temperature of 100 ℃ time runs in the oven of the box form, the foregoing glass is the size of the screen 130 inches or more large-area smart glass, the frame has a plurality of surfaces is formed to include, if from the surface of the plurality of the front is open side such that the first glass is exposed, except for the front are formed in the second glass and the ultrashort focus compartments which beam projects a housing the closed surface, the lower end of the frame, characterized in that a plurality of wheels disposed.
