Title: (EN) METHOD, SYSTEM AND COMPUTER READABLE STORAGE MEDIUM FOR DRIVING LIQUID CRYSTAL DISPLAYS
Abstract: front page image
(EN)

A method for driving the liquid crystal display comprises dividing a screen of the liquid crystal display into multiple displaying regions, and performing a divisional driving thereto, setting a backlight parameter corresponding to each the displaying region to a first backlight parameter during a first half of a time period of one frame, wherein the first backlight parameter is smaller than or equal to a maximum backlight parameter, setting the backlight parameter to a second backlight parameter during a second half of the time period, wherein the second parameter is smaller than a first threshold value, to have a default frame inserted during the second half of the time period of the one frame, and a difference between a gray level of the default frame and a gray level of a full black frame is within a predetermined range. The technical solution can improve blurred pictures.
