The invention relates to a plate display in ellipse start 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 ellipse start cathode array emission structure are arranged on the cathode glass panel. The invention can effectively utilize the phenomenon that the edge position emits lots of electrons, to increase the emission area of cathode, and improve the electron emission efficiency of carbon nanometer tube, to improve the control property of grid and improve the display image quality of whole device, with lower cost and simple structure. |
