Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.
[0037] Such as image 3 As shown, the present invention includes a sealed vacuum chamber formed by a cathode panel 1, an anode panel 11 and surrounding glass enclosures 8, an anode conductive layer 12 photoetched on the anode panel 11, and a fluorescent phosphor prepared on the anode conductive layer 12. The powder layer 14, the supporting wall structure 9 and the accessory element 10 of the getter are provided with an integrated triangular-conical grid cathode structure on the cathode panel 1, wherein the grid 2 is located below the carbon nanotube cathode 7, controlling the carbon nanotube Electron emission from the cathode.
[0038] The fixed position of the integrated triangular pyramid-shaped gate cathode structure is installed and fixed on the cathode panel 1. There is a grid conducti...
