Abstract
A liquid crystal display (LCD) device, a controller thereof, and a driving method thereof are provided. The LCD device can include a liquid crystal display panel configured to display images, on which data lines and gate lines are disposed, and subpixels defined by the data lines and the gate lines are arranged; a gate driver configured to supply a scanning signal to the gate lines; a data driver configured to supply a data voltage to the data lines; and a controller configured to control the gate driver and the data driver, in which the LCD device operates in a first type of inversion when a driving frequency is in a first driving frequency range, and the LCD device operates in a second type of inversion different from the first type of inversion when the driving frequency is in a second driving frequency range different from the first driving frequency range.
