US Patent 7239079 Field emission display and manufacturing method thereof

A field emission display and a method of making the same. The field emission display uses a deflection electrode having at least two elements. By applying different combinations of voltages to these two elements of the deflection electrode, the direction that the electron beam travels can be carefully controlled so that it lands on the proper pixel and subpixel. A protective electrode can be further included to prevent static charge buildup on the structure and to prevent dispersion of the electron beam.
