Publication number: 20150200233Abstract: Systems, and methods for the design and fabrication of OLEDs, including large-area OLEDs with metal bus lines, are provided. Various bus line design rules for large area OLED light panels may include mathematical models developed to optimize bus line design and/or layout on large area OLED light panels. For a given panel area dimension, target luminous emittance, OLED device structure and efficiency (as given by the JVL characteristics of an equivalent small area pixel), and electrical resistivity and thickness of the bus line material and electrode onto which the bus lines are disposed, a bus line pattern may be designed such that Fill Factor (FF), Luminance Uniformity (U) and Power Loss (PL) may be optimized. One general design objective may be to maximize FF, maximize U and minimize PL. Another approach may be, for example, to define minimum criteria for U and a maximum criteria for PL, and then to optimize the bus line layout to maximize FF.Type: ApplicationFiled: December 2, 2014Publication date: July 16, 2015Inventors: Huiqing Pang, Peter Levermore, Emory Krall, Kamala Rajan, Ruiqing Ma, Paul E.
