Abstract: A pixel circuit, an organic electroluminenscent display panel and a display device. The pixel circuit comprises: a drive transistor, a drive control module, at least two split light emitting control modules and light emitting devices connected with output terminals of the split light emitting control modules in one-to-one correspondence respectively. Since the plurality of split light emitting control modules can split the driving total current signal outputted by the drive transistor based on the corresponding split control signal, the driving split current signal outputted to the corresponding light emitting device can be less than the driving total current signal. Thus, the driving current of the light emitting device under the same brightness can be reduced, thereby being capable of realizing adjustment of various gray scale display of the high current efficiency light emitting device.
