ABSTRACT:
A circuit for variably controlling the frame ratio of a liquid crystal display (LCD) according to an operation mode, and a method for variably controlling the same are provided. A method for displaying received data on a liquid crystal display (LCD) includes the steps of selecting a power save mode, determining whether a data write enable signal for instructing received data to be displayed on an LCD panel is activated, outputting a first frame ratio when the data write enable signal is activated and outputting a second frame ratio when the data write enable signal is deactivated, and displaying the received data on the LCD panel according to the first frame ratio or the second frame ratio. The first frame ratio is larger than the second frame ratio.
