The invention relates to a plate display in junction field effect transistor cathode control 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 to adjust the emission electron ability of carbon nanometer tube cathode relative to the pixel point to make it emit electron uniformly and stably; a control grid, a carbon nanometer tube cathode and junction field effect transistor cathode control array emission structure are arranged on the cathode glass panel. The invention can effectively reduce the working voltage and improve the production success, with lower cost and simple structure. |
