The invention relates to a plate display in polygon six-edge radiation cathode 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 polygon six-edge radiation cathode emission structure are arranged on the cathode glass panel. The invention can effectively shorten the distance between grid and cathode, reduce the working voltage of device, and improve the control efficiency and control function of grid, with lower cost and simple structure. |
