摘要： 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.

摘要： The preset disclosure provides a display control method, a timing controller IC and a display device. The method includes: acquiring a preset grayscale voltage of a target pixel unit and a backlight brightness of a backlight region corresponding to the target pixel unit, in a current output display frame; outputting a first grayscale voltage to the target pixel unit if the backlight brightness of the corresponding backlight region is less than or equal to a first preset brightness value; outputting a second grayscale voltage to the target pixel unit if the backlight brightness of the corresponding backlight region is greater than the first preset brightness value; wherein the second grayscale voltage is greater than the first grayscale voltage, and both the second grayscale voltage and the first grayscale voltage are greater than the preset grayscale voltage.
