Abstract
The present disclosure provides conversion circuit and operation method thereof, compensation device, and display apparatus. The conversion circuit includes a conversion unit connected between an output terminal and a first voltage terminal, and an input unit connected with an input terminal and the conversion unit respectively; the input unit is configured to receive current signal from the input terminal and supply the current signal to the conversion unit, and the conversion unit is configured to convert the current signal supplied by the input unit into voltage signal and output the voltage signal from the output terminal; and an equivalent resistance of the conversion unit is configured such that preset voltage corresponding to standard current is output from the output terminal when the standard current is input from the input terminal. With the technical solutions of the present disclosure, drive current for pixel can be accurately converted into voltage signal.
