    摘要： Provided is a liquid crystal display device that can further reduce flicker. The liquid crystal display device includes a control unit that controls the luminance of a backlight using PWM dimming. The backlight includes n (n‰¥4) number of backlight blocks that are turned on at different timings, and the n number of backlight blocks are turned on in an order different from the order in which the backlight blocks are physically arranged.

    摘要： A display device with which a favorable trade-off between the scan effect and the luminous efficiency can be obtained is provided.
    A liquid crystal display device 200 includes a liquid crystal panel 220, a backlight panel 210 which has backlights 211 a to 211c and a backlight drive circuit 600 which outputs drive current of the backlights 211 a to 211 c, the duty ratio and the amplitude of which are changeable. The backlight drive circuit 600 outputs the drive current based on duty ratio characteristics that the duty ratio is greater as the luminance of the backlights 211a to 211c is higher and amplitude characteristics that is divided with a predetermined luminance as a boundary into the first region, which is less than or equal to the predetermined luminance, and the second region, which is higher than the predetermined luminance, and that the change rate of the amplitude of the drive current with respect to the luminance is less than or equal to the predetermined change rate in the first region, and the change rate of the amplitude of the drive current with respect to the luminance is greater than the predetermined change rate.

    摘要： 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.
