Abstract: A display device includes a substrate; and a red pixel electrode, a green pixel electrode, and a blue pixel electrode disposed on the substrate. Each of the red pixel electrode, the green pixel electrode, and the blue pixel electrode includes a transverse stem portion, a longitudinal stem portion, and a fine branch portion. An angle between the transverse stem portion and the fine branch portion of the red pixel electrode, an angle between the transverse stem portion and the fine branch portion of the green pixel electrode, and an angle between the transverse stem portion and the fine branch portion of the blue pixel electrode are different from each other.

Abstract: A display device includes a timing controller configured to generate an image signal including a pre-emphasis voltage, a data driver configured to generate a plurality of data signals based on the image signal, and provide information about whether the image signal is normally received or not to the timing controller, and a display panel configured to receive the plurality of data signals and display images corresponding to the received data signals, where when the data driver fails to normally receive the image signal, the timing controller increases a level of the pre-emphasis voltage.

Abstract: A transmitter includes a transmission controller which outputs original data through an original data lane, an encoder which encodes the original data into encoded data and outputs the encoded data through an encoded data lane, and a transmission driver which outputs the encoded data at a speed of M (M is a real number greater than 0) gigabits per second through a transmission and reception interface. The transmission driver provides a first clock signal corresponding to an output speed to the encoder, the encoder provides a second clock signal having a second frequency less than a first frequency of the first clock signal to the transmission controller, the transmission controller outputs the original data based on the second clock signal, and the encoder outputs the encoded data based on the first clock signal.

Abstract: A data receiver, which communicates with a data transmitter through a plurality of lanes, includes: a first reception unit which receives first data through a first lane; a second reception unit which receives second data through a second lane; and a detector which compares the first data and the second data to detect a skew between the first lane and the second lane. The first reception unit includes a first clock data recovery unit which recovers a first clock and first payload data from the first data. The first reception unit controls a loop speed of the first clock data recovery unit based on a skew level of the skew.

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 includes a transmitter and a receiver which are connected to each other through a first line and a second line. The transmitter transmits a first clock training pattern to the receiver in a first period, transmits a second clock training pattern and a first first payload to the receiver in a second period, and transmits a third clock training pattern and a second first payload to the receiver in a third period. The first clock training pattern, the second clock training pattern, and the third clock training pattern are variable based on a plurality of driving modes.

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.
