Abstract

The invention relates to a field emission display including a first substrate, a second substrate, a gap structure and a temperature adjusting layer, wherein the first substrate and the second substrate are opposite to each other, the gap structure is arranged between the first substrate and the second substrate, and the gap structure comprises a first end connecting with the first substrate and a second end connecting with the second substrate. When the field emission display is operated, the temperature difference between the first end and the second end is about zero to twenty degrees. The field emission display solves the problem that electron beams are likely to deviate due to non-uniform distribution of electric field between the negative plate and the positive plate of a conventional field emission display.

Description

technical field [0001] The present invention relates to a display, and in particular to a field emission display. Background technique [0002] The luminescence principle of field emission display is to use electric field to attract electrons from the tip of the material in a vacuum environment, and the field emission electrons leaving the cathode plate are attracted by the acceleration of the positive voltage on the anode, and hit the phosphor on the anode to emit light (Luminescence) . The cathode plate is used as a field electron emission source, and the anode plate is used as a light emitting source. The electrons emitted from the cathode plate hit the fluorescent layer on the anode plate to emit light. [0003] As mentioned above, when electrons are attracted by the acceleration of the positive voltage on the anode and collide with the phosphor on the anode, heat will be generated in addition to light. Therefore, when the field emission display is operated for a perio...
