OLED器件光电性能集成测试系统研制

摘要

In order to test the performance of organic light-emitting devices(OLEDs),an integrated photoelectric performance test system for OLEDs was designed and developed. The performances of the OLEDs (such as voltage-current,brightness,spectrum,chromaticity coordinates,lifetime,etc) could be measured in the same software. The communication routine between personal computers and the individual test equipments was described. The elec-troluminescent(EL) properties of OLEDs can be successfully obtained through simple control in a general computer. Using MFC (Microsoft Foundation Classes),a development tool of Microsoft Visual 2005,one convenient graphical user interface was successfully developed. Real-time display of the test process about the devices was realized through TeeChart (a graphical software developed by Steema). Furthermore,the characteristics of different devices could be compared by showing their curves in the same diagram. In addition,one CIE chromaticity coordinates assistant tool was developed,thus we manage to analyze the EL spectra and obtain the CIE chromaticity coordinates of the devices.%为方便对OLED器件的各项性能进行测试,研发了一种OLED器件光电性能集成测试系统,实现了在同一个软件下的OLED器件的电压、电流、亮度、光谱、色坐标和寿命等特性的集成测试.介绍了计算机与各测试设备的通信方法,通过计算机控制测量仪器对OLED器件进行测量.使用了Microsoft Visual 2005开发工具,利用MFC(Microsoft Foundation Classes)开发出了图形用户界面下的应用程序.利用TeeChart(西班牙Steema公司研发的图表控件)控件实现了OLED器件性能特性曲线的实时动态显示,并能够对不同器件的测试结果进行性能曲线的对比.编写了色坐标助手软件,实现对测试软件测试的光谱数据的分析显示功能.
