Abstract
Disclosed are a gray scale voltage compensation method of a liquid crystal panel, a circuit for a liquid crystal panel and a liquid crystal panel including the circuit. The invention adjusts the common voltage and/or compensates the pixel voltage to minimize the afterimage of the whole liquid crystal panel under the premise of saving the cost of the liquid crystal panel and greatly improves the panel display performance.
