Beschreibung
Zusammenfassung:	The invention relates to a method for preparing an optical membrane, which includes the following steps: providing a base material; forming a pattern with a first surface energy on the surface of the base material; printing a resin solution with a second surface energy on an area except the pattern by utilizing a screen; removing the screen and carrying out a drying procedure, thereby forming the optical membrane. Through the manufacturing procedure of screen printing, the invention can improve the yield of the optical membrane, and solve the problem of error caused by wicking action through utilizing the surface energy of the resin solution being difficult from that of the pattern material. Therefore, the yield can be greatly improved, the patterns required by the period of the manufacturing procedure can be finished in batch mode.
