Abstract:
1. A processing method of a flat panel display apparatus in which a cathode panel having electron emitting regions arranged on a supporting plate along a row direction and a column direction in a 2-dimensional matrix form and an anode panel having phosphor regions and an anode electrode are joined in a peripheral portion, spacers are arranged between the cathode panel and the anode panel along the row direction, and a space sandwiched between the cathode panel and the anode panel is held in a vacuum state, comprising the steps of: (A) applying a first voltage to each of the electron emitting regions to thereby allow electrons to be emitted from each of the electron emitting regions and measuring initial electron emitting states in electron emitting regions in at least a first row and a second row; and (B) executing an aging process by applying a second voltage to a first electron emitting region and a third voltage to a second electron emitting region, wherein the first electron emitting region is in a first row measured in step (A) to show a high initial electron emitting state, and the second electron emitting region is in a second row measured in step (A) to show a low initial electron emitting state, wherein the second voltage is higher than the third voltage.
