Abstract
An apparatus for generating a planar light source and method for driving the same is provided. The apparatus for generating a planar light source comprises an emitting layer disposed not only on a cathode electrode, but also on a gate electrode as well. Accordingly, by applying an AC voltage to the apparatus, a duty cycle of the AC voltage can reach 100% so as to enhance the brightness to the extent that the apparatus is applied a DC voltage.
Claims10
A planar light source generating apparatus, comprising:
- an anode plate, comprising a first glass substrate and a fluorescent layer;
- a cathode plate disposed on the anode plate, comprising a second glass substrate, a plurality of cathodes, a plurality of gates and a plurality of electron emission layers, wherein the cathodes and the gates are interleaved and disposed on the second glass substrate, and the electron emission layers entirely covers each top surface of the cathodes and the gates.
