    Abstract: Disclosed is a display device that can rapidly recover from a fail situation. The display device includes: a display panel; a source drive IC configured to supply a data signal to the display panel and including a calibrating unit; a timing controller configured to supply a data control signal and a frame data to the source drive IC; and a common bus line formed between the source drive IC and the timing controller. The calibrating unit sets and stores a calibration value in response to the data control signal during an initialization period before receiving the frame data from the timing controller, and transmits the calibration value to the timing controller through the common bus line.

    Abstract: A transceiver includes a transmitter and a receiver connected to each other through a first line and a second line. The transmitter transmits signals having a first voltage range to the first line and the second line in a first mode, and transmits signals having a second voltage range less than the first voltage range to the first line and the second line in a second mode. In transmitting a (1-1)-th payload to the receiver, the transmitter is sequentially driven in the first mode, the second mode, and the first mode, and transmits a first clock training pattern and the (1-1)-th payload in the second mode. The receiver includes a clock data recovery circuit generating a first clock signal corresponding to the received first clock training pattern and a register storing first frequency information and first phase information of the first clock training pattern.

    Abstract: A transceiver device includes a transmitter and a receiver connected through first and second lines. A first frame period includes an active period for transmitting a first payload and a vertical blank period including a frequency hopping period. The transmitter transmits, to the first and second lines, signals having a first voltage range in a first mode and signals having a second voltage range in a second mode. The transmitter generates a first horizontal synchronization signal in the second mode except for the frequency hopping period, encodes the first horizontal synchronization signal to horizontal synchronization data, and generates a second horizontal synchronization signal in the first mode in the frequency hopping period. The transmitter adds a first clock training pattern to the horizontal synchronization data except for the frequency hopping period, and adds a second clock training pattern to first horizontal synchronization data after the frequency hopping period.
