Abstract: A field emission backlight module has a field emission structure with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light. The light is emitted uniformly without the need of the conventional optical membrane. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a precision spacer to adjust the distance between the cathode and the anode, enabling the module to be manufactured at reduced cost and high good yield. When the color sequential displaying method is adopted, expensive color filters required in the conventional LCD may be omitted.
