Abstract
A display apparatus comprises a liquid crystal display panel, gate driver circuit for scanning gate lines of the display panel, drain driver circuit for supplying the display data to drain lines of the display panel, level modulator circuit coupled to the display panel and control circuit. The control circuit determines that video data represents a still image data, stoped the operation of the drain driver circuit and activates the level modulator circuit. The level modulator circuit reads out from display signals from the display panel and re-writes display signals to the display panel in order to display the still image on the display panel. In this manner, the electric power consumed by the drain circuit can be conserved when the display apparatus displays the still image.
