The backlight source comprises a vacuum sealing body and a getter accessory component located in the vacuum sealing body. The vacuum sealing body is composed of a front transparent hard glass plate, a rear transparent hard glass plate anda narrow glass frame strip. An anode pad film conduction layer, an anode gray silver-connected electric layer and a thin light-emitting layer are arranged on the front transparent hard glass plate. The anode pad film conduction layer is connected with the anode gray silver-connected electric layer, and the thin light-emitting layer is manufactured on the anode pad film conduction layer. The reartransparent hard glass plate is provided with an angular thorn circumferential double-connection-surface cathode alternate oblique bow gating structure. The luminous backlight source has advantages that a manufactured structure is simple, light-emitting brightness of the luminous backlight source is high and light-emitting gray scale adjustable performance of the luminous backlight source is excellent.

AI Technical Summary

Problems solved by technology

[0003] However, there are still some technical difficulties to be solved in the light-emitting backlight with three-pole structure

For example, first, the electron emission efficiency of the carbon nanotube cathode is very low

Among the prepared carbon nanotube cathodes, some carbon nanotubes can emit more electrons, some carbon nanotubes can only emit less electrons, and even a considerable part of carbon nanotubes do not emit electrons at all. , so generally speaking, the electron emission efficiency of the carbon nanotube cathode is very low, and it is also very unfavorable to form a large cathode current of the luminescent backlight

Second, the control performance of the gate voltage on the carbon nanotube cathode is very poor

Third, the fabrication area of ​​the carbon nanotube cathode is very small

The manufacturing area of ​​the carbon nanotube cathode is small, that is to say, the number of carbon nanotubes is reduced, which is very unfavorable for forming a large cathode current of a luminescent backlight
