The invention relates to a plate display in bidirectional annular 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 bidirectional annular adjusting structure are arranged on the cathode glass panel. The invention can use two conductive grooves to adjust the current of cathode to control the electron emission ability of cathode to realize the uniformity and stability of display image, with lower cost and simple structure. |
