Abstract: Provided is a communication system including a first electronic device and a second electronic device connected with each other through first and second channels. The second electronic device includes a reception driver generating a first internal signal based on a first data signal provided by the first electronic device through the first channel, an error detector generating an error detection signal by determining whether an error is included in the first internal signal, and an error adjuster outputting a first feedback signal through the second channel based on the error detection signal, and the first electronic device outputs a second data signal having a voltage swing width determined based on the first feedback signal through the first channel.

Abstract: The present disclosure provides transmitter circuits and display devices including the same. In some embodiments, the transmitter circuit includes a run length detector, a modifier, and a scrambler. The run length detector is configured to derive position information indicating a first input data related to a threshold run length from among a plurality of input data in a predetermined bit unit, when a run length of first scrambled data for the first input data meets or exceeds the threshold run length in the predetermined bit unit. The modifier is configured to generate modified input data by inverting at least one bit of the first input data based on the position information. The scrambler is configured to receive the modified input data from the modifier, and generate second scrambled data by scrambling the modified input data with scrambling information.
