In this work, we fabricate 1-in carbon nano tubes (CNTs) flat lamp of diode and triode structure. The CNTs have been directly grown on soda-lime glass substrate by thermal growth method. To know the optimized flat lamp structure, we have simulated the electric field distribution in these structures by the Maxwell simulator. The metal-mesh grid is inserted between an anode and cathode plate for dispersion of emitted electrons and decrease of turn-on voltage, and we investigate the trajectory of emitted electrons in the triode structure. Also, we suggest the direct joint packaging method, which needs no exhausting hole and tube. The CNTs flat lamps are successfully packaged and fully emitted with high brightness. The emission and brightness properties of CNTs are investigated for various conditions.
