  • Publication number: 20180190238
    Abstract: The present disclosure relates to a display interface device which can increase display information transmission efficiency and reduce power consumption and EMI, in which a transmission part transmits clock edge information included in a data packet of each channel at a different timing from clock edge information included in data packets of other channels. A reception part detects a clock edge of each channel from the data packet transmitted through each channel, generates an internal clock signal of each channel, synchronized with the detected clock edge, corrects a delay of each channel depending on a result of a logical operation performed on a delayed clock edge of a channel and a clock edge of another channel to further generate an internal clock signal of each channel, and restores the display information from the data packet of each channel using the internal clock signal of each channel.
