Abstract
We numerically analyzed the relationship between the electro-optical properties and the on-voltage of a TFT-LCD in a single-polarizer reflective double-layered TN-LCD (DTN-LCD) with a retardation film in order to confirm the possibility of reducing power consumption. Our results demonstrate that the LCD exhibits an achromatic image of high luminous reflectance of about 50% and very high contrast ratio, even if the on-voltage is reduced to 2 V. The power consumption can thus be decreased to about 1/6 that of the presently used reflective 5 V TFT-LCD in the on-state.
