Abstract
Recently, low-frequency driving of a display panel to reduce the power consumption has drawn much attention, especially in mobile devices. In case a liquid crystal display panel is driven by a fringe-field at a low frequency, the image flickering phenomenon can be observed when the sign of the applied electric field is reversed. Image flicker can be eliminated simply by applying a bias voltage to a liquid crystal cell so that the transmittance during the positive frame is the same as that during the negative frame. However, it may be difficult to employ this technique for practical applications because it requires a bias voltage that is dependent on the gray level. In this talk, we introduce methods to eliminate the image flicker by controlling the material parameters of liquid crystals, such as the flexoelectric anisotropy and the dielectric anisotropy. Methods to eliminate image flicker without controlling the material parameters, such as driving by a bipolar wave and optimization of the electrode spacing, are also introduced.
