  • Patent number: 8232953
    Abstract: A liquid crystal display device which includes a drive circuit capable of reducing electromagnetic wave noises while performing a high-definition multi-grayscale display is provided. In a liquid crystal display device, low-voltage differential signals divided into a plurality of channels are received by a receiving circuit, display data is recorded in a storage element after being arranged, and the display data is outputted to drive circuits on a liquid crystal display panel from a transmitting circuit at different frequencies. A display region of the liquid crystal display panel is divided into a plurality of divided display regions, and respective divided display regions differ from each other in the number of pixels thus making transmission clock frequencies different from each other.
