ABSTRACT:
An LCD apparatus including a first member, a second member, a liquid crystal layer and an optical film assembly is presented. A phase delay of the optical film assembly is about −α. In a normally white mode, the phase delay of the liquid crystal layer is about (λ/2)+α when no voltage is applied and about “α” when voltage is applied. In a normally black mode, the phase delay of the liquid crystal layer is about “α” when no voltage is applied, and about (λ/2)+α when voltage is applied. The phase delay between the liquid crystal layer when voltage is applied and the liquid crystal layer when voltage is not applied is about λ/2. “α” is a positive number. By manipulating the value of α, power consumption can be reduced. For example, the apparatus can be driven with a voltage below 2.5 V.
