Abstract
A gate off delay compensation circuit includes a sensing interval determiner configured to determine an interval in which a driving voltage corresponds to a first and second level of a reference voltage as a driving voltage sensing interval, a driving voltage excess interval determiner configured to determine a driving voltage excess interval defined as an interval in which the driving voltage is larger than the reference voltage and a driving voltage period determiner configured to determine a period of the driving voltage based on the driving voltage sensing interval and the driving voltage excess interval. Therefore, a gate off delay compensation circuitdecreases an average driving current and an average driving voltage and allows decrease of a variation of a driving current according to a change of a input voltage V.
