  • Patent number: 7474369
    Abstract: A pixel device of a transflective-type LCD comprises an upper panel, a lower panel, a liquid crystal layer, and a liquid crystal film. The lower panel is assembled beneath the upper panel, and an upper surface of the lower panel is divided into a reflective region and a naked transmission region. The liquid crystal layer is interposed between the upper panel and the lower panel. The liquid crystal film is positioned above the liquid crystal layer to compensate possible retardation resulted from the liquid crystal layer.

  • Patent number: 7379138
    Abstract: In a transflective LCD, it is possible to cause the change in the optical characteristics of the liquid crystal layer in the transmission area between operating states to be different from the change in the optical characteristics of the liquid crystal layer in the reflection area by using different applied voltages in the transmission and reflection areas. In the first operating state, the liquid crystal layer in the transmission area and the liquid crystal layer in the reflection area are used as a half-wave plate to change the linear polarization axis of the traversing light. In the second operating state, the liquid crystal layer in the transmission area does not affect the polarization axis of the traversing light, but the liquid crystal layer in the reflection area is used as a quarter-wave plate. As such, no additional half-wave plates and quarter-wave plates are needed.
