Integral organic light emitting diode printhead










Image Number 8 for United States Patent #6606110.

A compact light weight printhead capable of direct quasi-contact printing includes an OLED structure deposited onto a substrate. The printhead is designed for contact or quasi-contact printing, without additional optical elements. The printhead design ensures that the desired pixel sharpness and reduced crosstalk is achieved. Two possible different arrangements for the printhead are disclosed. One arrangement includes at least one array of OLED elements. Each OLED array in this arrangement includes at least one triplet of OLED elements, and each element in each the triplet is capable of emitting radiation in a distinct wavelength range different from the distinct wavelength range of the other two color filters in the same triplet. In the second arrangement, the printhead includes at least one triplet of arrays of individually addressable Organic Light Emitting Diode (OLED), elements. In this second arrangement, each OLED array in each triplet has elements that are capable of emitting radiation in a distinct wavelength range different from the distinct wavelength range of the other two arrays in the triplet.
