Abstract
There provides a liquid crystal display apparatus and a backlight control method thereof. The liquid crystal display apparatus includes an image data acquisition part, a liquid crystal panel, a panel driving unit, a backlight module and a backlight driving unit; wherein the panel driving unit drives the liquid crystal panel and generates a backlight driving signal; the backlight driving unit includes a PWM module and a PFM module to modulate the backlight driving signal, thereby forming driving powers supplied to the backlight module; the liquid crystal display apparatus further includes a backlight modulation selection unit used to detect and calculate an average pixel brightness value A of the image data, and a reference pixel brightness value Ais further set therein; when A≥A, the backlight modulation selection unit selects to enable the PWM module; and when A<A, the backlight modulation selection unit selects to enable the PFM module.
