Abstract

A driving method of a display unit includes: executing a first display procedure, for displaying a first frame on a display unit of the display driving circuit, and executing a counting mechanism; determining, if a second display procedure for displaying a second frame on the display unit is confirmed to be executed, whether or not a counting value of the counting mechanism is larger than a predetermined value; sequentially executing a specific display procedure and the second display procedure if the counting value is larger than the predetermined value; and directly executing the second display procedure if the counting value is equal to or smaller than the predetermined value. A display driving circuit applicable to be used by the display unit is also provided.

Description

technical field [0001] The present invention relates to a picture driving method, and in particular to a display unit driving method and its driving circuit. Background technique [0002] Among current displays, electrophoretic displays have been gradually favored by consumers in recent years due to advantages such as low power consumption and readability. Although the electrophoretic display only consumes power at the moment of changing the image, the viscosity of the insulating solvent will limit the moving speed of the charged colored particles, so when the current image is displayed, the previous image may appear afterimage phenomenon. Especially when the display time of the previous frame is too long, the image sticking phenomenon is more obvious. Contents of the invention [0003] The invention proposes a driving method of a display unit and a driving circuit thereof, so as to improve the image sticking phenomenon that is easy to occur in current displays (eg, bist...
