Abstract: The present disclosure generally relates to a method of sensing characteristic value of circuit element and display device using it, which may shorten the threshold voltage sensing and compensation time of the driving transistor and the threshold voltage compensation time driving transistors by sensing the threshold voltage in a mobility sensing period of the driving transistor, calculate the threshold voltage using two or more sensing values of driving current for the driving transistor.
