Method of manufacturing protective lens for display

A method for manufacturing a filtering film, said method comprising the steps of:

• forming a mold, the mold having a printing surface in which a plurality of recesses defines;
• flooding the printing surface with ink so as to fill the recesses with the ink;
• removing excess ink from the printing surface with a portion of the ink remained in the recesses;
• positioning an elastically deformable body on the printing surface;
• pressing the elastically deformable body against the printing surface so that the ink in the recesses attaches to a surface of the elastically deformable body;
• providing a piece of membrane;
• moving and positioning the elastically deformable body with the ink attached thereto on the membrane;
• pressing the elastically deformable body against the membrane to transfer the ink to the membrane, thereby forming ink stripes on the membrane.

A method of making a protective lens with a curved configuration thereof, comprising the steps of:

• (1) providing a mold with a plurality of unequally spaced recesses therein;
• (2) filling said recesses with printing ink;
• (3) providing a piece of membrane with a configuration compliant with the protective lens;
• (4) transferring the printing ink from the mold unto said membrane thus forming a filtering film thereof;
• (5) providing a glass substrate;
• and
• (6) attaching the filtering film to the glass substrate thus forming the protective lens thereof.
