Four blue organic light emitting diodes (OLED) based on anthracene derivatives( ADN) doped with different dopants have been prepared. The device structure is CuPc(12 nm)/NPB(40 nm)/ADN∶Dopant(50 nm)/Alq(12 nm)/LiF(4 nm)/Al. The four dopants are amino-substituted distyrylarylene derivatives(BCzVB), tetra-butylperylene (TBPe), BCzVBi and DSA-ph. The optium concentration of dopants, the luminescence, current density, efficiency and color coordinates of these devices are explored. The device based on ADN doped with BCzVB shows high color purity and a weak current-induced fluorescence quenching. With CIE coordinates x=0.146,y=0.162, maximum luminance 11600 cd/m2 (15 V), current efficiency 2.8 cd/A, and luminous efficiency 1.79 lm/W. For comparison, the blue OLEDs based on ADN doped with TBPe BCzVBi and DSA-ph are also made. The first exhibits CIE coordinates x=0.162, y=0.222 (greenish blue) and a steep decline of efficiency with the increase of the current. The second gives a better purity (x=0.164,y=0.146) but lower current steeply declining with increase of current efficiency 2.03 cd/A. The last has high efficiency 8 cd/A and a weak current-induced fluorescence quenching, but poor CIE coordinates x=0.153，y=0.306, and it is suitable for white OLED.
