Abstract
A liquid crystal display apparatus includes a liquid crystal panel and a panel driving device. The panel driving device includes a timing control circuit, a gate driving circuit, and a source driving circuit. The source driving circuit includes a low voltage differential signal (LVDS) receiver, a driving voltage generator, and a controller. The LVDS receiver includes a plurality of receive circuits and a power saving control circuit. Each of the receive circuit performs level conversion upon a data LVDS to generate a logic signal, and operates in a selected one of a normal energy consuming mode and a power saving mode. The power saving control circuit controls the receive circuits to operate in the power saving mode when the power saving control circuit does not receive a power adjustment signal from the controller.
