The invention relates to a field activated emission plate display in curved grid frame sharp 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; a control grid, a carbon nanometer tube cathode and curved grid frame sharp array emission structure are arranged on the cathode glass panel. The invention can effectively strengthen the control function of grid, shorten the distance between grid and cathode, reduce the working voltage, utilize the phenomenon that the edge position emits lots of electrons, improve the electron emission efficiency of cathode, and improve the display brightness, with lower cost and simple structure. |
