ABSTRACT
A white organic light emitting device with structure of ITO/2T-NATA(20)/NPBX(15)/DPVBi(15)/ AlqRub(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.
