Abstract: A method for prolonging the life span of a planar light source generating apparatus is provided. The planar light source generating apparatus forms an emitting layer not only on a plurality of cathodes but on a plurality of gates as well. Moreover, an anode of the planar light source generating apparatus is electrically connected to a current sensor for reading out a maximum current density when the planar light source generating apparatus operates. To operate the planar light source generating apparatus, a DC square voltage is applied to the cathodes (or gates) while the gates (or the cathodes) are electrically connected to a ground. Once the current density detected by the current sensor drops to a definite ratio of the maximum value, the external voltage supplying the aforementioned cathodes and the gates are switched. Thus, the life span of the planar light source generating apparatus is prolonged.

Abstract: A quadrode field emission display is provided, where a low driving voltage is reached by an edge structure, and display in the dark is achieved by adding a sub-gate electrode. With respect to the electrical characteristics that an edge structure may raise the electric field intensity, an edge of a cathode plate through an opening of a gate layer is exposed, thereby forming the edge structure at an emitter to raise the electric field. It also reduces the driving voltage substantially. Therefore, the display in the dark is achieved by adjusting the voltage without changing the structure.
