The invention relates to a plate display in chrysanthemum grid control 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 hrysanthemum grid control cathode array emission structure are arranged on the cathode glass panel. The invention can effectively increase the emission area of cathode; improve the electron emission efficiency of carbon nanometer tube and the control property of grid structure to improve the image quality, with lower cost and simple structure. |
