Abstract

In this study, we report that an electrical properties of OLEDs was investigated by the surface etching method of ITO Layer. The electrical properties of OLEDs was measured by IVL and optical properties by EL spectrum. The fundamental structure of OLEDs was ITO anode/TPD(400$\breve{A}$)/$Alq_3(600\breve{A})$/LiF(5$\breve{A}$)/Al(1200$\breve{A}$) cathode. The threshold voltage was low value according to the low resistance of surface. The luminance was increased by decreased surface resistance.
