Abstract
A material for blocking crosstalk, an optical assembly, and a method for preparing the material are provided. The optical assembly includes an optical receive assembly, where a periphery of the optical receive assembly includes a transparent region and a non-transparent region; the transparent region is made of the material, where a first layer of film is located on a side opposite to an optical receiving direction, and a second layer of film is located on a side opposite to the optical receive assembly; and the non-transparent region is of an electrical-signal shielding structure.
Claims12
A material for blocking crosstalk, the material comprising:
- a first layer of film;
- a nonconductive substrate;
- and
- a second layer of film,
- wherein the first layer of film and the second layer of film are respectively plated on two sides of the substrate, alternately arranged grids and grid lines are disposed on only an exterior surface of the first layer of film, and the first layer of film is non-hollowed-out.
A method for preparing a material for blocking crosstalk, the method comprising:
- plating a second layer of film on a first side of a nonconductive substrate, wherein the second layer of film can transmit light with a first wavelength and reflect light with a second wavelength;
- and
- attaching a composite transparent conductive oxide (TCO) thin film material to a second side of the substrate, and preparing grids on only an exterior surface of the composite TCO material, wherein the grids and grid lines are arranged alternately, to form a first layer of film that is non-hollowed-out;
- or
- preparing grids on only an exterior surface of a composite TCO material, wherein the grids and grid lines are arranged alternately, to form a first layer of film that is non-hollowed-out, and attaching the first layer of film to a second side of the substrate.
