Study on AC-Driving Circuit for OLED

提出并设计了一种有机电致发光显示器交流电压驱动电路,在验证此电路性能的同时也对有机电致发光显示器在交流驱动下的特性进行了测试。研究结果表明,交流驱动电路工作性能良好,在实现交流的同时抑制了交叉效应的产生,并能够大幅度地提高有机电致发光显示器的寿命。在对有机电致发光显示器交流驱动下的特性研究中发现:改变交流驱动的频率会影响发光像素点的性能,频率在50Hz左右的交流驱动是最适合有机电致发光显示器。

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.
