Abstract
Embodiments of the present disclosure disclose a current control method and an apparatus thereof. The current control method includes: generating a correspondence between grayscale brightness and a current of a display panel; detecting, in a blank interval of a display period, an actual current value and an actual grayscale brightness of the display panel; determining a target current value by looking up a correspondence between the grayscale brightness and the current according to a target grayscale brightness of the display panel; and adjusting, based on a comparison of the actual current value and the target current value, the actual grayscale brightness so that the actual current value is less than or equal to the target current value.
