Light blocking plate, lens module having same, and method for making same

A lens module comprising:

• a lens;
• and
• a light blocking plate with the lens attached thereto, the light blocking plate comprising:
• a flat plate-like light pervious member;
• and
• a blocking and shielding layer, the blocking and shielding layer comprising a top surface facing away from the light pervious member, a bottom surface facing the light pervious member, and a through hole extending from the top surface to the bottom surface, the through hole being coaxial with the lens,
• wherein the blocking and shielding layer comprises an electromagnetic shielding layer having a first part of the top surface, and a light blocking layer, the light blocking layer including a first portion having the bottom surface, and a second portion having a second part of the top surface, and extending from the first portion to the second part of the top surface, the electromagnetic shielding layer surrounding the second portion of the light blocking layer, the second portion of the light blocking layer surrounding the through hole.

A method for making a light blocking plate, comprising:

• providing a flat plate-like light pervious member;
• forming a plurality of spaced ceramic power layers on the light pervious member;
• forming a light blocking layer over the light pervious member and side faces of the ceramic power layers;
• forming an electromagnetic shielding layer over the light blocking layer;
• removing top portions of the ceramic power layers with remaining portions of the ceramic power layers exposed to an outside;
• removing the remaining portions of the ceramic power layers.
