A white organic light emitting device with structure of ITO/2T-NATA(20)/NPBX(15)/DPVBi(15)/ Alq:Rub(10, x)/Alq3(40)/LiF/Al was fabricated using doping rubrene. When the concentration of rubrene is 3 wt.%, the chromaticity is the best (0.319, 0.317), and the color coordinates are stable. When the thickness of the doping layer is 20 nm, the efficiency and luminance of the devices are the highest, which are 5.1022 cd/A and 17130 cd/m2, respectively. On the basis, a test system is consisted of Solomon's OLED display control driver chip SSD1306 and microcontroller AT89C52, which tests the OLED dot matrix through the program to determine whether the matrix has dead point. Through experimental comparison, the test results are consistent with the external power supply test. The system has the characteristics of high efficiency and display characters of dynamic and static pictures, which provides a feasible driving method for the practical application of OLED.
通过掺杂红荧烯制备了结构为ITO/2T-NATA(20)/NPBX(15)/DPVBi(15)/Alq:Rub(10, x)/Alq3(40)/LiF/Al的白色有机发光器件。当红荧烯浓度为3 wt.%时，色度最佳(0.319, 0.317)，且色坐标稳定。当掺杂层厚度为20 nm时，器件的效率和亮度最高，分别为5.1022 cd/A和17130 cd/m2。在此基础上，由所罗门OLED显示控制驱动芯片SSD1306和微控制器AT89C52组成测试系统，通过程序对OLED点阵进行测试以确定点阵是否有坏点。经实验比较，测试结果与外部电源测试结果一致。该系统具有高效的特点，可显示动态和静态图片，为OLED的实际应用提供了一种可行的驱动方法。
