Abstract
A method for detecting a threshold voltage of a driving transistor includes: obtaining at least one first threshold voltage of at least one driving transistor when each driving transistor is driven by a corresponding first driving signal; obtaining a threshold reference voltage of the driving transistor according to the at least one first threshold voltage; obtaining a second driving signal of the driving transistor according to the threshold reference voltage and the first driving signal of the driving transistor, a value of the second driving signal being greater than a value of the first driving signal; and obtaining a second threshold voltage of the driving transistor when the driving transistor is driven by the second driving signal.
