Abstract

The invention provides a driving method of a display unit and a driving circuit thereof. The driving method comprises the following steps: performing a first display program to display a first picture on the display unit and start a counting mechanism; judging whether the counting value of the counting mechanism is larger than a preset value or not before a second picture display program is determined to perform; firstly performing a special picture display program and then performing the second picture display program when the counting value is determined to be larger than the preset value; performing the second picture display program to display a second picture on the display unit when the counting value is determined to be smaller than or equal to the preset value.

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...
