Annular blade type cathode emitting structural panel display device and its production technique

Abstract

The invention relates to a plate display in annular blade cathode 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 annular blade cathode emission structure are arranged on the cathode glass panel. The invention can effectively utilize the phenomenon that the edge position emits lots of electrons, improve the electron emission efficiency of cathode, and improve the display brightness of device, with lower cost and simple structure.
