A transflective LCD panel includes scan lines, data lines, transmissive pixels and reflective pixels. Each transmissive pixel is configured to receive a transmissive pixel voltage transmitted from one of the data lines and displays a first gray level related to the transmissive pixel voltage. Each reflective pixel receives a reflective pixel voltage transmitted from one of the data lines and displays a second gray level related to the reflective pixel voltage. When the transmissive pixel and the reflective pixel are used to display a same gray level, the transmissive pixel voltage and the reflective pixel voltage are predetermined such that corresponding first and second gray levels substantially equal each other.
