A stabilized OLED device for emitting light of a specific color includes a metallic anode and a metallic cathode spaced from the metallic anode. The device also includes a light-emitting layer including a host and a dopant, the dopant selected to produce light having a spectrum including light of the specific color, and a stabilizer provided in one of the device layers which improves the useful lifetime of the OLED device, wherein the stabilizer has an emission spectrum different from that of the light-emitting layer. One of the electrode layers is semitransparent and the other one is substantially opaque and reflective such that the stabilized OLED device forms a microcavity that emits a narrow band light with the specific color.

A method of printing using an electrohydrodynamic printing system includes providing an electrohydrodynamic printing system. The electrohydrodynamic printing system includes a nozzle that dispenses a printing fluid and a substrate that receives the printing fluid. The nozzle includes a conductive portion. A voltage source applies a voltage differential between the conductive portion of the nozzle and the substrate. A controller is configured to control the voltage source such that the printing fluid is deposited on the substrate. The method includes causing a drop of the printing fluid to be formed from the conductive nozzle by using the controller to provide a burst mode waveform to the voltage source.

A liquid stream is caused to jet from a nozzle. A small or large drop waveform applied to a drop forming mechanism causes the liquid stream to break up into a small or large volume drop, respectively. The small drop waveform includes a pulse having a width wS, and a period x, where x≈1/fR, where fR is the Rayleigh frequency of the liquid. The large drop waveform includes a period Nx, with the large volume drop being N times the small volume drop. The large drop waveform includes a first pulse having a pulse width wL1, where wL1≧wS, and a second pulse occurring within a period of (fR/fC)x of an initial pulse of a subsequent small or large drop waveform, where fC is the cut off frequency of the liquid.

A liquid stream is caused to jet from a nozzle. A small or large drop waveform applied to a drop forming mechanism causes the liquid stream to break up into a small or large volume drop, respectively. The small drop waveform includes a pulse having a pulse energy Es, and a period XS, where XS≈1/fR, and where fR is the Rayleigh frequency of the liquid. The large drop waveform has a period XL, where XL=NXS, with the large volume drop being N times the small volume drop.
