Abstract: Driving method and circuit of an organic light emitting diode, applied to an array of a plurality of organic light emitting diode. The array has several rows and columns of organic light emitting diodes. The row and column corresponding to the organic light emitting selected to illuminate are selected. A first voltage is applied to the selected column, and a second voltage is applied to the selected row. The difference between the first and second voltages is larger than the conducting voltage of the organic light emitting diode, so that the light emitting diode can illuminate. A third voltage and a fourth voltages are applied to other rows and columns which are not connected to the selected organic light emitting diode to provide a reverse bias to all the remaining light emitting diodes.

Abstract: A method of fabricating an emitter of a field emission display. A mixture of metal and silver paste with glass material is screen printed on a substrate as a silver electrode. The metal is selected from a hard solder alloy such as Al/Si alloy containing tin, zinc, aluminum or other low melting point metal. Alternatively, the metal and the silver paste with the glass material are separately screen printed on the substrate. The metal is selected from tin, zinc, aluminum, or an alloy with a low melting point such as aluminum/silicon alloy. A carbon nano-tube layer is formed on the silver electrode by coating the carbon nano-tube material with the electric arc. Alternately a catalyst layer can be formed on the silver electrode prior to the formation of the carbon nano-tube layer. A metal layer such as nickel and copper is formed on the carbon nano-tube layer to prevent the carbon nano-tube layer from absorbing gas.
