Design and Fabrication of Passive Matrix Organic Light-emitting Diodes

Crosstalk,equivalent circuit,voltage drop and power consumption of passive matrix organic light-emitting diodes(OLEDs) were quantitatively analyzed,and a mathematical model to calculate the power of passive matrix OLEDs was builted.The model demonstrate that the power of dual dual-scan OLEDs can be significantly reduced compared with that of single-scan OLEDs,because the scanning duty increase 100%.Two 64 mm.128×64 pixels green small molecule OLEDs has been fabricated.One was adopted single-scan method,and the other dual-scan method.Compared with single-panel OLEDs,the power consumption of dual-panel OLEDs show a reduction of 25%,when both were operated at the average luminance of 100 cd/m~2.
