Title: (ZH) 一种灰阶控制方法、灰阶控制装置及液晶显示屏
Abstract: front page image
(ZH) 本发明实施例公开了一种灰阶控制方法、灰阶控制装置及液晶显示屏,其中灰阶控制方法可包括:将液晶显示屏的有效显示区域划分为至少两个子区域;实时获取所述至少两个子区域中各个子区域的灰阶值,并根据获取的灰阶值确定所述各个子区域当前所在的灰阶区间;根据所述液晶显示屏当前的背光驱动电流、所述各个子区域当前所在的灰阶区间以及预设的背光驱动电流、灰阶区间和灰阶补偿值之间的对应关系对所述各个子区域的灰阶值分别进行补偿。采用本发明实施例,可对有效显示区域中各个子区域的灰阶值分别进行补偿,从而提高液晶显示屏的亮度均匀性。
