Abstract:
1. A method for updating a display image of an electrophoretic display panel, the electrophoretic display panel having a plurality of gate lines and a gate driver, each of the gate lines being coupled to a plurality of pixels and the gate driver, the method comprising: dividing the gate lines into a first group and a second group, wherein display data relates to the pixels coupled to the gate lines of the first group need not to be updated, and display data relates to at least one of the pixels coupled to the gate lines of the second group need to be updated; and providing a first type gate pulse to each gate line of the first group and providing a second type gate pulse to each gate line of the second group, wherein the second type gate pulse has a predetermined pulse width, and a pulse width of the first type gate pulse is shorter than the predetermined pulse width, and the first type gate pulse and the second type gate pulse are obtained by adjusting the clock cycle of a clock signal provided to the gate driver.
