Abstract: A transceiver includes a transmitter and a receiver coupled to each other through a first line and a second line. The transmitter transmits a first voltage signal of a second logic level or a fourth logic level, among a first logic level, the second logic level, a third logic level, and the fourth logic level, through the first line. The transmitter transmits a second voltage signal of the first logic level or the third logic level through the second line. The receiver generates an output signal having one of four values based on the first voltage signal and the second voltage signal.

Abstract: A transceiver device 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. The transmitter encodes an original payload to generate a first payload in the second mode, and transmits a clock training pattern and the first payload through the first line and the second line. The receiver decodes the first payload and outputs reception data corresponding to the original payload in the second mode.

Abstract: A 3-dimensional image display device includes a signal controller, a data driver, a display panel, and glasses. The signal controller includes a reference gamma data generator to correct image data. The data driver includes a gray voltage generator to generate a gray voltage based on the corrected image data. The display panel displays left-eye and right-eye images based on a data voltage from the data driver. The lenses of the glasses are controlled by a glasses synchronization signal from the signal controller, to compensate for charging rates of the left-eye and right-eye images.

Abstract: A transceiver includes a transmitter and a receiver connected to each other by a first line and a second line. The transmitter transmits signals each having a first voltage range to the first line and the second line in a first mode, and signals each having a second voltage range less than the first voltage range to the first line and the second line in a second mode. The receiver includes a low-power driver which receives signals through the first line and the second line in an operating state of the first mode, and stops an operation thereof in the second mode, and a high-speed driver which receives signals through the first line and the second line in the second mode, and stops an operation thereof in the first mode.

Abstract: A display device may include a timing controller, a data driver and a plurality of pixels. The timing controller supplies a clock training pattern over a data/clock signal line in a first time period, and supplies pixel/control data over the data/clock signal line in a second time period. The data driver generates a clock signal, using the clock training pattern, in the first period, and generate a plurality of data voltages based on the plurality of pixel data, using the clock signal, in the second period. The plurality of pixels receive the plurality of data voltages and emit corresponding light. During the second period, the data driver outputs a feedback signal to the timing controller indicating that the locking of the clock signal has failed. The timing controller re-supplies the clock training pattern in response to the feedback signal.

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.
