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