Abstract
A driving method includes: determining a starting luminance Lof a to-be-adjusted frame image; determining an average luminance L(n) of the to-be-adjusted frame image during a nth duty period; determining a reference luminance flow rate ΔL that indicates a current change rate of a storage capacitor storing a data signal for a display element; determining a time length Tof a reference frame image; determining a number k of black strips in the to-be-adjusted frame image; calculating a duty ratio of a pulse driving signal of the to-be-adjusted frame image during the nth duty period based on the starting luminance L, the average luminance L(n), the reference luminance flow rate ΔL, the time length T, and the number k of the black strips; and driving to display the to-be-adjusted frame image by the adjusted pulse driving signal.
