Abstract

A driving device of a bistable electro-optic display and a driving method thereof are disclosed. The driving device comprises an image processing unit, a display processing module and a scheduling module. The image processing unit receives a first update block of a display area and generates first block update information based on the first update block. The display processing module updates the display area according to the first block update information. During the update of the first block, the image processing unit is capable of continuously obtaining at least one second update block, thereby generating second block update information. After the first block is updated completely, the scheduling module controls the display processing module so that the display processing module updates the display area according to the second block update information, thus shortening the time for updating the display area.

Description

technical field [0001] The present invention relates to a driving technology of an optoelectronic display, and in particular to a driving technology of a bistable electro-optic display which schedules the processing operation of update blocks, so as to shorten the display time. The update time for the zone. Background technique [0002] Due to the advantages of being light, thin, short, and small, liquid crystal displays have gradually become display tools for portable terminal systems (such as smart phones and notebook computers) in recent years, and have become indispensable daily necessities for people. As for the power supply problem of the portable terminal system, the power saving effect of the liquid crystal display still needs to be worked hard. [0003] Bistable photoelectric display (bistable, electro-optic display) technology is currently the display technology with the best power-saving effect, which can keep the bistable display unit (pixel) stably at "Bright ...
