Abstract
The present disclosure provides a driving circuit and driving method for a liquid crystal display panel, and a display device. The driving circuit includes: a signal collector, configured to collect a backlight control signal; and a timing control chip, configured to determine whether a BLU is in the bright state time period or in the dark state time period, and retrieve a first gate control signal from a memory chip and output the first gate control signal to a gate driving circuit, when determining that the BLU is in the bright state time period, or retrieve a second gate control signal from the memory chip and output the second gate control signal to the gate driving circuit, when determining that the BLU is in the dark state time period.
