Invalid line identification-based ink screen rapid refresh driving method and device

Abstract

The invention discloses an ink screen rapid refreshing driving method and device based on invalid line recognition, and belongs to the field of ink screen display driving. The method comprises the following steps: acquiring a current image and a new image; querying a waveform file to generate a plurality of refresh frames according to the gray values of the pixel points of the current image and the new image; for each refresh frame, identifying whether each row of pixel data in the refresh frame is all zero, and adding an effective row identifier at the front end of each row of data; reading the expanded refresh frames in sequence, and when each row is driven, firstly judging an effective row identifier of the row; if the identifier indicates that the line is valid, driving the line of data to be written into a screen according to a normal time sequence; and if the identifier indicates that the line is invalid, shortening the grid activation time of the line in a mode of improving the grid driving clock frequency, and quickly skipping. According to the invention, by identifying and quickly skipping the invalid lines, the time waste in the driving process is reduced, the image refreshing speed of the ink screen is obviously improved, and the user experience is improved.
