Semiconductor integrated circuit, self-luminous display panel module, electronic apparatus, and method for driving power supply line

A display device comprising:

• a plurality of pixels;
• and
• control circuitry configured to drive the pixels,
• wherein each of the pixels includes an organic EL element, a drive transistor and a capacitor configured to store a signal voltage, the organic EL element and the drive transistor being connected serially between a power supply line and a cathode electrode,
• the drive transistor is configured to provide a current flow from the power supply line to the organic EL element in response to the signal voltage,
• the control circuitry is configured to drive each of the pixels so as to change a potential of the cathode electrode relative a power supply potential of the power supply line in response to an adjustment of a peak luminance level, and
• the control circuitry is further configured to control each of the pixels, within a one-frame period, to:
• receive an image signal potential while the organic EL element is fixed to a reverse-biased state, and then,
• repeatedly turn on and turn off the organic EL element without applying a reverse-biased voltage in a light emission period, wherein respective periods of the turning on and the turning off of the organic EL element are changed based on the adjustment of the peak luminance level.
