  • Abstract: ?In this paper, we investigated the switching behaviour of homogeneously-aligned LCs over a wide temperature range. We found that the slower response time at low temperature can be compensated by a higher electric field so that 3T cell using new drive scheme can offer a complete solution. In contrary to the fringe-field-switching (FFS) cell, the response time of a 3T cell showed an extremely mild increase as the temperature decreases because all GTG switching is controlled by applying a high electric field. At -20¡ÆC, the slowest GTG response time of an FFS cell was 77.33 ms, whereas the slowest GTG response time of the 3T cell using the new drive scheme was 6.15 ms at the same temperature, as shown in Fig. 1. This is approximately 12.5 times shorter than that of an FFS cell. This can be an effective solution for removing the motion blur in LCDs at a low temperature.
