Display driving circuit, display device, and display driving method

A display driving circuit for driving a display panel which includes

• scan signal lines, data signal lines, pixel electrodes, switching elements, and capacity coupling lines, wherein the scan signal lines turn on and off the switching elements corresponding thereto, and each of the switching elements has (i) one terminal connected with one of the respective pixel electrodes and (ii) another terminal connected with one of the respective data signal lines, and the capacity coupling lines are capacity-coupled with corresponding ones of the pixel electrodes, wherein each of the scan signal lines forms a row together with switching elements connected thereto, pixel electrodes respectively connected to these switching elements, and one of the capacity coupling lines capacity-coupled with these pixel electrodes, the display driving circuit driving the display panel to carry out a gradation display in accordance with electric potentials of the pixel electrodes,
• the display driving circuit comprising:
• a scan signal line driving circuit for driving the scan signal lines;
• a data signal line driving circuit for outputting a data signal which is based on a video signal;
• and
• a capacity coupling line driving circuit for outputting a potential shift signal whose electric potential is switched over in a certain way in accordance with a polarity of the data signal,
• for each row, the capacity coupling line driving circuit outputting a potential shift signal to a row in accordance with an output signal outputted to the row from the scan signal line driving circuit.
