Abstract:
Embodiments of the disclosure disclose a LED backlight driving circuit, including a power source, LED strings, a buck circuit, and a LED controller. The LED strings include at least one string of LED lamps, a positive terminal thereof and the power source are electrically connected. The buck circuit and the LED strings are electrically connected. The LED controller and the buck circuit are electrically connected. The LED controller controls the power source to provide electricity to the LED strings and controls the buck circuit to store energy during a first period. The LED controller controls the buck circuit to provide electricity to the LED strings during a second period. The disclosure further provides a liquid crystal display. The disclosure has the advantage of preventing the LED backlight driving circuit from being damaged easily.
