The invention relates to a plate display in bended probe grid control cathode 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 bended probe grid control cathode structure are arranged on the cathode glass panel. The invention can effectively shorten the distance between grid and cathode, reduce the working voltage, strengthen the surface electric field on the carbon nanometer tube, improve the control efficiency and control function of grid and improve the display image quality of whole device, with lower cost and simple structure. |
