Abstract
A liquid crystal display (LCD) device with a driving method includes an LCD panel, a data driving circuit, a common voltage generating circuit, and a gate driving circuit. The LCD panel includes multiple data lines and multiple scanning lines intersecting with the data lines, and a common electrode. The gate driving circuit provides multiple gate-scanning signals to scan the scanning lines. The common voltage generating circuit provides a common voltage to the common electrode. The data driving circuit provides a gray level voltage signal including multiple voltage levels to the data lines. The common voltage is serial square waves having at least two non-identical frame periods. The square waves in each non-identical frame period of the common voltage in one frame have a constant period.
