The display data related to pixels coupled to the gate lines of the first group need not to be updated. Furthermore, the display data related to at least one of the pixels coupled to the gate lines of the second group need to be updated. The first type gate pulses are provided to the gate lines of the first group respectively, and second type gate pulses are provided to the gate lines of the second group respectively. The second type gate pulse has a predetermined pulse width. The pulse width of the first type gate pulse is shorter than the predetermined pulse width.
