Problems solved by technology

But not all electrons fly vertically to the anode glass panel, and some electrons will fly to the supporting wall structure in a disorderly manner; when the electrons bombard the supporting wall structure, secondary electrons will be excited from the supporting wall structure, and other The emission of secondary electrons will have a certain impact on the display device, which in turn will affect the display image quality of the device, and in severe cases will lead to the burning and scrapping of the entire display device

Embodiment Construction

[0041] 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.

[0042] The present invention includes a sealed vacuum chamber composed of an anode glass panel 5, a cathode glass panel 9 and a surrounding glass frame 14. An anode conductive strip 6 and a phosphor layer printed on the anode conductive strip 6 are arranged on the anode glass panel 5. 8. On the cathode panel 9, a cathode conductive strip 10, an insulating spacer layer 11, a printed carbon nanotube cathode 13, a control grid strip 12 for controlling electron emission, and an auxiliary getter element 15 are arranged in a sealed vacuum chamber A support wall structure is provided which can not only provide support for the glass panel, but also prevent secondary electron emission on the support wall structure.

[0043] The support wall structure for preventing secondary electron emission compris...

Abstract

The invention relates to carbon nanometer tube cathode filed-emissive plane luminous display and its making craft, which comprises a sealed vacuum chamber formed by an anode glass plane, a cathode glass plane and around glass frame, wherein the anode glass plane arranges an anode conducing bar and a luminescent powder layer which is printed on the anode conducing bar; the cathode glass plane arranges an cathode conducing bar, an insulating isolate layer and a printed carbon nanometer tube cathode, a control grid bar used to control the electron ejection and a belong gettering unit; it arranges the supporting wall structure which can provide the supporting function to the glass plane and avert the secondary electron ejection of the supporting wall structure.

Description

technical field [0001] The invention belongs to the intercrossing fields of nanometer science and technology, flat panel display technology and vacuum science and technology, and relates to the production of flat field emission light-emitting display devices, and specifically relates to the content of the device production of flat field emission display devices of carbon nanotube cathodes The invention relates in particular to a manufacturing process of a field emission planar display device with a carbon nanotube cathode having a supporting wall structure for preventing secondary electron emission. Background technique [0002] Flat panel displays have made great progress in recent years due to their advantages of large area, planarization, and high quality. Carbon nanotubes are a kind of cathode emission material with a unique structure, which can emit a large amount of electrons under the action of an applied voltage, which has attracted the attention of many researchers....
