Study of a new type anode of OLED by MIC poly-si

In this paper, a boron-doped poly-Si crystallized by solution-based metal induced (S-MIC) as the anode of organic light emitting diode (OLED) was studied. The semi-transparent and semi-reflective anode of OLED systemized with the high reflectivity of Al cathode could form a micro-cavity structure with a low Q to improve the efficiency. The maximum luminance efficiency of red OLED made by Alq3: DCJTB (1.5wt %)(30nm) with the poly-Si anode is 2.66cd/A, higher than that of the OLED with the ITO anodes by 30%. In order to improve the device performance, some key to optimize the character of MIC poly-Si thin film are analyzed theoretically. A new kind of TFT/OLED coupling structure in AMOLED was proposed, in which the pixel electrode of OLED was made by the same poly-Si thin film with its driver TFT's drain electrode. So that this coupling structure will simplify the AMOLED processes flow
