Abstract: A liquid crystal display (LCD) and an operating method thereof are provided. The operating method includes the following steps. It is determined whether a first frame and a second frame following the first frame are dynamic frames. When the first frame and the second frame are dynamic frames, a timing controller of the LCD performs a polarity inversion on a polarity signal, so that the polarity signal corresponding to the first frame is the same as the polarity signal corresponding to the second frame. When the second frame is written into an LCD panel of the LCD, energy written into the LCD panel is reduced.

Abstract: A method and system of controlling halt and resumption of scanning actions of an LCD is disclosed. An incoming video source is monitored, and current scan line position and corresponding polarity are recorded. When an abnormal video source is detected, the LCD scanning is stopped at a halt scan line of a halt frame with a halt polarity. After a normal video source has been detected again, determination is made of a proper resumptive scan line and/or a resumptive polarity. The panel scanning is resumed at the resumptive scan line equal to the halt scan line and/or with the resumptive polarity matching the halt polarity.
