The invention relates to a plate display in alternative cathode adjusting 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 alternative cathode adjusting structure are arranged on the cathode glass panel. The invention can effectively adjust the ability of field activated electron emission of cathode, to make the cathode emit electrons uniformly and stably and improve the display brightness and light uniformity of whole device, with lower cost and simple structure. |
