Abstract:
1. A method for manufacturing a plane light source, the method comprising: providing a first transparent substrate; forming a plurality of electrode pairs on said first transparent substrate; forming a dielectric layer on said first transparent substrate and covering said plurality of electrode pairs; coating a plurality of phosphors on said first transparent substrate and heating said plurality of phosphors by microwave irradiation after an MgO layer is coated on surface of each of said plurality of phosphors, wherein coating said MgO layer on surface of each of said plurality of phosphors comprises: NaOH source to produce first aqueous solution, and heating said first aqueous solution to 140° C. temperature for 1 hour; providing a second transparent substrate; assembling said second transparent substrate with said first transparent substrate; and fulfilling an inert gas within said second transparent substrate and said first transparent substrate.
