A backlight control method and apparatus and a 3D display system are disclosed, and the method includes: dividing correspondingly a backlight source and a liquid crystal panel into N horizontal row sections, respectively; preprocessing 3D data images to obtain respectively first images and second images of left and right eyes output in a complementary format, which preserve odd and even row section images of original left-eye and right-eye images, and scanning the first images and second images of the left and right eyes sequentially from top to bottom according to the format and sequential order of the outputted images; and after an image preserving an odd or even row section is scanned, controlling the backlight of the row section to be turned on and then turned off until a next image preserving the odd or even row section starts to be scanned, and repeating this process until the scanning ends. With the invention, dynamic control is performed on the row sections of the backlight source in cooperation with image processing and display to achieve a crosstalk-free 3D effect and reduce power consumption of both the backlight source and the system. |
