Light-emitting backlight source of double-probe curved gating structure of cathode with different vertical separation degree and same concave surface

Abstract

The invention discloses a light-emitting backlight source of a double-probe curved gating structure of a cathode with different vertical separation degree and the same concave surface. The light-emitting backlight source comprises a vacuum sealing body and a getter accessory element positioned in the vacuum sealing body, and is characterized in that the vacuum sealing body consists of a front hardtransparent glass plate, a rear hard transparent glass plate and a narrow glass frame strip; the front hard transparent glass plate is provided with an anode material film base flat layer, an anode extension system silver bent layer and a thin light-emitting layer, the anode material film base flat layer is connected with the anode extension system silver bent layer, and the thin light-emitting layer is manufactured on the anode material film base flat layer; and the rear hard transparent glass plate is provided with a double-probe curved gating structure of the cathode with the same concavesurface and different vertical separation degrees. The light-emitting backlight source has the advantage of being excellent in light-emitting intensity uniformity.

Second, the gate voltage has poor control over the electron emission from the CNT cathode

On the one hand, the electric field intensity formed by the gate voltage on the surface of the carbon nanotube layer is not completely consistent, which also leads to the phenomenon that some carbon nanotubes can emit electrons, and some carbon nanotubes cannot emit electrons; on the other hand, Larger gate voltage is very easy to cause electrical breakdown between gate and cathode
