Abstract

The present invention relates to a field emission display in which a gate plate having a gate hole and a gate electrode around the gate hole is formed between an anode plate having phosphor and a cathode plate having a field emitter and a control device for controlling field emission current, wherein the field emitter of the cathode plate is constructed to be opposite to the phosphor of the anode plate through the gate hole. According to the present invention, it is possible to significantly reduce the display row / column driving voltage by applying scan and data signals of the field emission display to the control device of each pixel, And the present invention is directed to improve the brightness of the field emission display in such a manner that the electric field necessary for field emission is applied through the gate electrode of the gate plate to freely control the distance between the anode plate and the cathode plate, so that a high voltage can be applied to the anode.

Description

technical field [0001] The present invention relates to a kind of field emission display (FED) that field emission device is applied to flat panel display, relate in particular to a kind of field emission display, wherein have field emitter and be used to control field emission current in an anode plate with phosphor A grid plate is formed between a cathode plate of the control device, and the grid plate has a grid hole and a grid electrode around the grid hole, wherein the field emitter of the cathode plate passes through the grid hole and the grid electrode of the anode plate Phosphor relative configuration. Background technique [0002] A field emission display is a device that displays images through the cathode electron excitation light of a phosphor, using electrons emitted from the field emitter of the cathode plate to collide with the phosphor of the anode plate, where the cathode plate with the field emitter and the phosphor with the phosphor The anode plates are o...
