Abstract:
1. A driving method for a bistable display device, comprising: when displaying a first frame, setting a first duration of a first frame and a second duration of the first frame according to a frame period of the first frame; applying a first voltage to a light valve layer in the first duration according to display data for the light valve layer to enter a second state from a first state for the bistable display device to display a dark image; and applying a second voltage to the light valve layer in the second duration for the light valve layer to enter the first state from the second state for the bistable display device to display a bright image; wherein if the first voltage applied is a high voltage, sub frame periods in the first duration in which the first voltage is applied are continuous, and a reset is not required when switching to a next frame, thereby reducing voltage variations and saving power consumption.
