DISPLAY FILTER, MAKING METHOD THE SAME AND DISPLAY APPARATUS USING THE SAME

摘要

A display filter making method the same and display apparatus using the same is provided to increase the brightness of a display and improve electromagnetic shielding and contrast. A display filter(100) includes a base part(110) and a dark color part which is formed the base part and has a magnetic material which is a needle or flat type. The magnetic material is one Fe2O3 or Fe3O4 and is arranged perpendicularly to the surface of the base part. A manufacturing method includes steps: mixing the magnetic material which is a needle or flat type with the base part; aligning the magnetic material to be perpendicular to the surface of the base part through external magnetic field; annealing the base part and the magnetic material.
