OLED current detection circuit and OLED screen display show system

The utility model discloses a OLED current detection circuit and OLED screen display show system, OLED current detection circuit is including being used for making the luminous inferior pixel circuitof output current detected signal of OLED, a drive detection chip for driving the work of inferior pixel circuit, a detection module for receiving inferior pixel circuit's current detection signal handles it, inferior pixel circuit is connected to the detection module, the drive detects the chip and connects inferior pixel circuit and detection module simultaneously, and the detection module is received current detection signal to judge according to the pre -defined algorithm whether unusual inferior pixel circuit's operating current is through drive detection chip. The event the utility modeldiscloses can detect OLED's operating current and judge whether unusual it is through effectual, in time break off the power supply of shielding OLED through main control chip when its appearance isunusual, prevent fever scre
