Abstract
A transflective LCD. The transflective LCD includes multiple pixels. Each pixel includes a reflective cell and a transmission cell. The reflective cell has a first storage capacitor and a first active device, receiving a first driving voltage and coupling to the first capacitor. The transmission cell has a second storage capacitor and a second active device, receiving a second driving voltage and coupling to the second capacitor. Different from only single driving voltage in conventional transflective LCD, the first driving voltage and the second voltage are generated according to a reflective gamma curve and a transmission gamma curve respectively.
