Mask having raised supporting bodies

Abstract

A mask structure having raised supporting bodies is provided between an anode plate and a cathode plate to form a gate electrode layer. The mask is provided thereon with a plurality of apertures that are arranged at intervals. The plate surface of the mask is provided with a plurality of raised supporting bodies that are arranged on the plate surface of the mask at intervals and are adhered to the cathode plate to form a support and separation between the mask and the cathode plate. Finally, the surface of the raised supporting body is provided with an electrode layer that is electrically connected with the cathode plate, thereby providing the necessary power supply for the mask serving as the gate electrode layer. In this way, the mask structure formed in single construction can be packaged directly with the cathode plate and the anode plate. Therefore, in addition to reduce the manufacturing cost, the risk of oxidization of the cathode electron emission sources occurred during the high-temperature sintering can be avoided.
