Abstract

A method for activating surface of electron emission source of a field emission display. After a cathode structure is fabricated and sintered with high temperature, the surface of electron emission source is activated by employing a spray coating technology. The spray coating technology includes a spraying device. The spraying device employs compressed air to homogeneously spray the solution onto the surface of the cathode structure. The solution will then cover the gate electrode layer and permeate into the hole and sagged area on the surface of electron emission source to form a covering layer. The covering layer is then dried and peeled off using a roller peeling device. The roller peeling device includes two rollers, one of which includes a heating unit to heat and soften the covering layer when rolled on the covering layer of the cathode structure. The other roller can thus peel off the covering layer easily.
