Claim:
1. A method for driving a reflective liquid crystal display (LCD) panel, wherein the reflective LCD panel comprises an active color beam source providing a color beam, comprising: driving the reflective LCD panel by a driving signal with alternate positive and negative polarities, wherein the driving signal is a common voltage having positive polarity for a first driving duration and negative polarity for a second driving duration during an image color field, wherein the first and second driving durations are consecutive and each consist of a first time period and a second time period, wherein in each of the first and second driving durations, the second time period is after the first time period, and the first time period is shorter than the second time period; providing, by the active color beam source, the color beam of the active color beam source to irradiate the reflective LCD panel during the second time period of the first driving duration, and not providing the color beam of the active color beam source to irradiate the reflective LCD panel during the first time period of the first driving duration; and providing, by the active color beam source, the color beam of the active color beam source to irradiate the reflective LCD panel during the second time period of the second driving duration, and not providing the color beam of the active color beam source to irradiate the reflective LCD panel during the first time period of the second driving duration, wherein the color beam of the active color beam source irradiates the same color during the first and second driving durations.
