Title:

MATERIAL AND OPTICAL ASSEMBLY FOR BLOCKING CROSSTALK AND MANUFACTURING METHOD FOR MATERIAL

Document Type and Number:

WIPO Patent Application WO/2016/041179

Kind Code:

A1

Abstract:

A material and optical assembly for blocking crosstalk and a manufacturing method for the material. The material comprises: a first layer of film (201), a substrate (202) and a second layer of film (203), wherein the first layer of film (201) and the second layer of film (203) are respectively plated on the two sides of the substrate (202), and the first layer of film (201) is non-hollowed-out and is provided with grid lines and lattices which are alternately arranged on the surface thereof. The optical assembly comprises: a receiving optical assembly (901), wherein the periphery of the receiving optical assembly (901) includes a light-transmitting area (902) and a non-light-transmitting area (903). The light-transmitting area (902) is made of the material, a first layer of film (902a) is arranged at one side opposite to a light-receiving direction, and a second layer of film (902c) is arranged at one side opposite to the receiving optical assembly (901); and the non-light-transmitting area (903) is of an electrical signal shielding structure. The material and optical assembly can guarantee complete isolation of light and spots, have no electromagnetic leakage and have a better shielding effect, thereby improving the receiving sensitivity and power.
