We present a method to enhance the image quality in low-power LCD using positive dielectric anisotropy LCs (pLCs). The proposed method to measure the flexoelectric coefficient difference (es – eb) enables precise material screening and optimized mixtures. The resulting pLC mixture shows minimized flexoelectric coefficient difference, brightness fluctuation under low-frequency driving.
