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

摘要

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 (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. OLED panels including bus lines with different resistances (R1) along a length of the bus line are also described.
