Protective lens for display and method of manufacturing the same

A method for manufacturing a protective lens, comprising the steps of:

• (1) forming a mold, the mold having a printing surface in which is defined a plurality of recesses;
• (2) flooding the printing surface with ink so as to fill the recesses with the ink;
• (3) removing excess ink from the printing surface with a portion of the ink remained in the recesses;
• (4) positioning an elastically deformable body on the printing surface;
• (5) 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;
• (6) providing a piece of membrane;
• (7) moving and positioning the elastically deformable body with the ink attached thereto on the membrane;
• (8) pressing the elastically deformable body against the membrane to transfer the ink to the membrane for forming ink stripes on the membrane to form a filtering film;
• (9) providing a transparent glass substrate;
• (10) attaching the filtering film to a surface of the glass substrate to form a protective lens.

• (6) providing a piece of membrane;
• (7) moving and positioning the elastically deformable body with the ink attached thereto on the membrane;
• (8) 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.
