METHOD, SYSTEM AND COMPUTER READABLE STORAGE MEDIUM FOR DRIVING LIQUID CRYSTAL DISPLAYS
First Claim
1. A method for driving a liquid crystal display, comprising:
- dividing a screen of the liquid crystal display into multiple displaying regions, and performing a divisional driving to the multiple displaying regions;
setting a backlight parameter corresponding to each the displaying region of the liquid crystal display to a first backlight parameter during a first half of a time period of one frame displayed by the liquid crystal display, wherein the first backlight parameter is smaller than or equal to a maximum backlight parameter of the each displaying region of the liquid crystal display; and
setting the backlight parameter corresponding to each the displaying region of the liquid crystal display to a second backlight parameter during a second half of the time period of the one frame displayed by the liquid crystal display, 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 displayed by the liquid crystal display, 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.

Abstract
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.

6. A system for driving a liquid crystal display, comprising:
-
a dividing module, for dividing a screen of the liquid crystal display into multiple displaying regions, and performing a divisional driving to the multiple displaying regions; a first setting module, for setting a backlight parameter of each displaying region of the liquid crystal display to a first backlight parameter, during a first half of a time period of one frame displayed by the liquid crystal display, wherein the first backlight parameter is smaller than or equal to a maximum backlight parameter of the each displaying region of the liquid crystal display; and a second setting module, for setting the backlight parameter corresponding to each the displaying region of the liquid crystal display to a second backlight parameter, during a second half of the time period of the one frame displayed by the liquid crystal display, 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 displayed by the liquid crystal display, 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. - View Dependent Claims (7, 8, 9, 10)
