LCD ESTIMATING DEVICE, AN LCD AND AN LCD ESTIMATING METHOD TO OBTAIN AN OPTIMAL OVERSHOOT PARAMETER

摘要

PURPOSE: An LCD(Liquid Crystal Display) estimating device, an LCD and an LCD estimating method are provided to easily obtain an optimal overshoot parameter at high accuracy. CONSTITUTION: A signal unit(3) provides signals to a liquid crystal panel(2). A display detecting unit(4) detects the display of the liquid crystal panel. An analyzing unit(5) analyzes the detected result of the display detecting unit. The signal unit provides a signal corresponding to an original gray to the liquid crystal panel, provides an overshoot signal, and provides a signal corresponding to an achievement gray. The analyzing unit analyzes each detected result from the display detecting unit, and stores the level of the overshoot signal corresponding to an optimal detection result in response to the original gray and the achievement gray.
