The invention relates to a plate display in coplanar current 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 coplanar current adjusting structur are arranged on the cathode glass panel. The invention can effectively control the shape of conductive groove via adjusting external voltage, to effectively control the current of cathode to improve the uniformity and stability of display image, with lower cost and simple structure. |
