Abstract: An AC-voltage driving circuit is proposed and designed. Meanwhile the test of the circuit and the characteristic of Organic Light-Emitling Device(OLED) under AC-voltage driving are studied. The relevant test and research show that the AC-driving circuit functions excellently, realizing AC driving and restraining the cross talk, and the lifetime of OLED can be improved greatly. Under the research of characteristic of AC driving, we find the performance of OLED's pixel is largely impacted by driving frequency and the frequency of 50 Hz is fit for OLED most.
