Driving circuit and display device

A driving circuit, comprising:

• an electrode driver outputting a first driving signal with a first voltage level to at least one common electrode of a plurality of common electrodes embedded in a panel during a first driving period, and a second driving signal with a second voltage level and a third voltage level to the at least one common electrode during a second driving period,
• wherein the second driving signal is a pulse signal, and the electrode driver receiving a sensing signal from at least one common electrode to which the second driving signal is applied during the second driving period;
• and
• a sensing signal converter outputting sensing data into which the sensing signal received during the second driving period is converted,
• wherein the second voltage level and the third voltage level differ from the first voltage level.

A display device, comprising:

• a plurality of gate lines and a plurality of data lines crossing one another;
• a first power circuit outputting a first voltage;
• a second power circuit outputting a second voltage and a third voltage,
• a data driving circuit outputting a data voltage to the plurality of data lines;
• a driving circuit outputting a first driving signal to at least one common electrode during a first driving period and a second driving signal to the at least one common electrode during a second driving period,
• wherein the first driving signal has a first level and the second driving signal has a second third voltage levels that are different from the first voltage level, and at least a portion of the first driving period and a portion of the second driving period overlap with a period during which the data driving circuit outputs the data voltage.
