A mono color organic light emitting diode matrix display was reported,which has been developed based on a long life green OLED cell with 96×60 pixels,an equivalent pixel size of 0 4×0 4mm 2 and a designed driving circuit.A good green color image could be obtained,neither non uniformity caused by the parasitic capacitance nor cross talk between pixels occurred.The peak luminance at the duty cycle 1/64 was 100cd/m 2,and power consumption was 0 6W. The display panel consists of a glass substrate on which ITO anodes are formed in vertical stripes with a width of 0 4mm and a gap of 0 1mm by photolithography,then the buffer layer,hole transporting layer,electron transporting layers were successively deposited,Mg∶Ag as a cathode was evaporated and formed in horizontal stripes with a width of 0 4mm and a gap of 0 1mm by a shadow mask.Then the panel was encapsulated and the electrodes of the display were connected with the driving circuit. For the driving circuit,a line successive scanning and a constant current driving were adopted.It was designed to eliminate the cross talk between the pixels,a good green color image was realized.

For the driving circuit, a line succeeded ssive scanning and a constant current driving were adopted. It was designed to eliminate the cross talk between the pixels, a good green color image was realized.
