Abstract
The present disclosure provides a temperature compensation method and device, and a display apparatus. In the temperature compensation method, a temperature value of a driving transistor corresponding to a light emitting device in the display apparatus is determined according to a photoelectric display signal of the display apparatus and/or an anode voltage signal of the light emitting device, and an electrical parameter offset of the driving transistor is calculated according to the temperature value, so as to perform real-time temperature compensation on a date line signal such as a gate voltage.
