A new liquid crystal fringe-field switching device with superior outdoor readability

A new liquid crystal (LC) device driven by fringe-field switching (FFS) with superior outdoor readability is proposed. In this structure, the bottom substrate has patterned floating metals which are positioned below the center of the pixel electrode and the center between pixel electrodes and above metals, in-cell retarder with quarter wave phase retardation (QWPR) exists and under them, compensation film with QWPR does. And light efficiency at these positions becomes maximal under any lighting conditions. As a result, it is possible for the new device to show both a single cell gap and superior outdoor readability even though it's not a transflective LC display.
