Abstract(in English) | The transients of the transmittance and the voltage holding ratio(VHR) of a liquid crystal cell were measured by the bipolar pulse driving in order to clarify the influence of residual DC voltage to image-sticking effects. The pulse voltage with the condition of half-tone image driving was applied to the LC cell involving ions after the DC voltage application to induce the residual DC voltage. The resultant transmittance of the cell was lower than that of the Unstressed level with increasing VHR as a function of DC application time. The drop of the transmittance is considered to be not caused by residual DC but the increase of the VHR due to decrease of mobile ion density. |
