Embodiment Construction
[0039] 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.
[0040] The flat-panel display with a ring grid-controlled valley-mouth type cathode structure includes a sealed vacuum chamber formed by an anode glass panel [13], a cathode glass panel [1] and surrounding glass frames [18]; There is an anode conductive layer [14] and a phosphor layer [16] prepared on the anode conductive layer on the glass panel; there are grid lead layer [3], carbon nanotubes [12] and ring gate control valley mouth on the cathode glass panel type cathode structure; supporting wall structure [17] and getter [19] accessory elements between the anode glass panel and the cathode glass panel.
[0041] The ring gate-controlled valley-mouth type cathode structure includes a cathode glass panel [1], a retardation layer [2], a grid lead layer [3], a grid booster layer [4], a grid e...
