Abstract: A transceiver of the present inventive concept includes a transmitter and a receiver connected by a first line and a second line, and the transmitter includes a first encoder; a second encoder; and a transmission driver. The first encoder generates a first encoded data different from a first data during a first period and the second encoder generates a second encoded data equal to a second data during the first period, the second encoder generates the second encoded data different from the second data during a second period and the first encoder generates the first encoded data equal to the first data during the second period, and the first period and the second period are arranged to alternate with each other.

Abstract: A display device may include display pixels configured to emit light at a luminance corresponding to a data signal, at least one auxiliary pixel configured to store an auxiliary voltage, a gate driver configured to supply a gate signal to the display pixels and the auxiliary pixel, a data driver configured to convert image data into the data signal, and supply an auxiliary voltage having a preset level to the auxiliary pixel. A sensing circuit is configured to sense a change in the auxiliary pixel for each frame, and generate compensation voltage information. A timing controller is configured to convert an image signal into the image data, and generate a driving voltage control signal. A voltage generation unit is configured to generate a driving voltage corresponding to the driving voltage control signal, and generate the reference gamma voltage based on the driving voltage.
