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. When transmitting a first payload to the receiver, the transmitter is sequentially driven in the first mode, the second mode, and the first mode, and the transmitter transmits a clock training pattern and the first payload in the second mode.

Abstract: A display device includes a display panel including a pixel, and a panel driver driving the display panel. The pixel includes first to fifth transistors. The first transistor is connected between a power line and the light-emitting element. The second transistor is connected between a data line and the first transistor and receives a first scan signal. The third transistor is connected between the first transistor and a first node and receives a second scan signal. The fourth transistor is connected between the first node and an initialization line. The fifth transistor is connected between the first transistor and the first node and receives a fourth scan signal. The first and fourth scan signals are simultaneously activated, and a period of the second scan signal is smaller than or equal to a period of the fourth scan signal.

Abstract: A display device includes a first pixel row, a first first-structure transmission line, a first second-structure transmission line, a first transistor, and a second transistor. The first pixel row includes a first first-color sub-pixel and a second first-color sub-pixel both for displaying a first color. The first second-structure transmission line neighbors the first first-structure transmission line with no intervening transmission line analogous to the first first-structure transmission line or the first second-structure transmission line being disposed between the first first-structure transmission line and the first second-structure transmission line. The first transistor is electrically connected through the first first-structure transmission line to the first first-color sub-pixel and receives a first test voltage. The second transistor is electrically connected through the first second-structure transmission line to the second first-color sub-pixel and receives a second test voltage different from the first test voltage.
