Bending effect on the circular polarizer of an organic light-emitting diode display
Abstract:
We investigated the retardation change of a reactive-mesogen-type quarter-wave plate (QWP) by bending. We measured the retardation of the QWP when the slow axis of the QWP was perpendicular or parallel to the bending axis. We simulated the effect of the retardation change on the antireflection property of a quasi-circular polarizer used for an organic light-emitting diode display. The light leakage was diminished with bending in the vertical viewing direction, while it was increased in the horizontal viewing direction regardless of the orientation of the slow axis.
