Design of passive matrix organic light-emitting diodes

摘要

The crosstalk, equivalent circuit, voltage drop and power consumption of passive matrix organic light-emitting diodes (PMOLEDs) are quantitatively analyzed, and a mathematical model to calculate the power of PMOLEDs is built. In particular, the advantages of dual-panel PMOLEDs are discussed. The model demonstrates that the power of dual-panel PMOLEDs can be significantly reduced comparing with that of single-panel PMOLEDs. Two 2.5-in. 128?64-pixel green small molecule PMOLEDs have been fabricated. One is single-panel, and the other dual-panel. The power consumption of dual-panel PMOLEDs is 25% less than that of single-panel when both are operated at an average luminance of 100cd/m2.
