Fluorescent powder mixture, manufacturing method for the same, and corresponding liquid crystal display device

摘要

The present invention relates to a fluorescent powder mixture, a manufacturing method for the same, and a corresponding liquid crystal display device. The fluorescent powder mixture is a mixture of a conductive powder and a fluorescent powder, wherein the conductive powder is aluminum zinc oxide, gallium zinc oxide, or indium tin oxide. The fluorescent powder mixture, the manufacturing method for the same, and the corresponding liquid crystal display device of the present invention increase the conductivity of the fluorescent powder, and further weaken the electron enrichment phenomenon on the surface of the fluorescent powder, so as to increase the illumination performance of the fluorescent powder.

主权项

1. A method for manufacturing fluorescent powder mixture, comprising steps of:
placing a raw material of a conductive powder in a container by using a solvent; after adding a stabilizer in the container, stifling for 4-6 hours under heating in 50-70° C. water bath, so as to obtain a precursor solution of the conductive powder; seasoning the precursor solution of the conductive powder under a temperature of 50-70° C. for 56-90 hours, so as to obtain a xerogel of the conductive powder; heating the xerogel of the conductive powder under a temperature of 600-900° C. for 1-5 hours, so as to obtain the conductive powder; and providing a fluorescent powder, and mixing the conductive powder with the fluorescent powder, so as to obtain the fluorescent powder mixture, wherein the raw material of the conductive powder is a mixture of aluminum salt and zinc salt, a mixture of gallium salt and zinc salt or a mixture of tin salt and indium salt; and the conductive powder is aluminum zinc oxide, gallium zinc oxide or indium tin oxide.
