The invention relates to a plate display in multi-annular cathode array emission structure and relative production, wherein it comprises an anode glass panel, a cathode glass panel, and a sealing vacuum chamber surrounded by four glass frames; the anode glass panel is arranged with anode conductive layer and a fluorescent powder layer is above the conductive layer; a support wall structure and a gattering additional element are between the anode glass panel and the cathode glass panel; a control grid, a carbon nanometer tube cathode and multi-annular cathode array emission structure are arranged on the cathode glass panel. The invention can effectively strengthen the electron emission control function of grid, to increase the emission area of cathode of carbon nanometer tube, and improve the control efficiency of grid, to improve the brightness, with lower cost and simple structure. |
