ABSTRACT:
A method for manufacturing a hologram projection screen includes the steps of: 1) recording hologram lens information on a photoresist plate; 2) metalizing the photoresist plate that has been exposed, to produce a master nickel plate of a hologram lens array through electroforming and joining; and 3) using the master nickel plate to emboss thermoplastic material, to obtain a screen body, on which the information of the hologram lens array is arranged. The hologram projection screen manufactured by this method can provide a variety of display contents.
