Abstract
An electron emission light-emitting device includes a cathode structure, an anode structure, a fluorescent layer, and a low-pressure gas layer. The fluorescent layer is located between the cathode structure and the anode structure. The low-pressure gas layer is filled between the cathode structure and the anode structure, having a function of inducing the cathode to emit electron uniformly. The low-pressure gas layer has an electron mean free path, allowing at least sufficient amount of electrons to directly impinge the fluorescent layer under an operation voltage.
Claims16
An electron emission light-emitting device, comprising:
- a substrate;
- at least one cathode structure, disposed on the substrate with direct contact;
- at least one anode structure, disposed on the substrate with direct contact;
- a fluorescent layer, disposed on the substrate with direct contact and located between the at least one cathode structure and the at least one anode structure;
- and
- a low-pressure gas layer, filled between the at least one cathode structure and the at least one anode structure, for inducing the cathode structure to emit electrons uniformly.
