Method of forming bus line designs for large-area OLED lighting

Abstract

Systems, and methods for the design and fabrication of OLEDs, including large-area OLEDs with metal bus lines, are provided. For a given panel area dimension, target luminous emittance, OLED device structure and efficiency, 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 to optimize Fill Factor (FF), Luminance Uniformity (U) and Power Loss (PL). Example designs may be to maximize FF, maximize U and minimize PL. or define minimum criteria for U and a maximum criteria for PL, and then to optimize the bus line layout to maximize FF. OLED panels including bus lines with different resistances along the bus line are also described.

Dependencies are inferred from the claim text.
