Display device

A display device comprising:

• a display region including a plurality of pixel circuit rows;
• and
• a driver circuit,
• wherein each of the plurality of pixel circuit rows includes a plurality of pixel circuits,
• wherein each of the plurality of pixel circuits includes:
• a driving transistor configured to control an amount of electric current to a light-emitting element;
• a storage capacitor configured to hold a control voltage for the driving transistor;
• a first transistor and a second transistor connected in series, the first and the second transistors being configured to transmit a data signal to the storage capacitor;
• and
• a threshold compensation transistor configured to write a threshold compensation voltage for the driving transistor to the storage capacitor,
• wherein the driver circuit is configured to shift control signal pulses from a row to a next row in the plurality of pixel circuit rows every time a predetermined period passes,
• wherein a pulse width of the control signal pulses is twice or more as long as the predetermined period,
• wherein the driver circuit is configured to:
• maintain the threshold compensation transistor to be ON to write a threshold compensation voltage to the storage capacitor in a threshold compensation period;
• and
• maintain the threshold compensation transistor to be OFF and the first transistor and the second transistor to be ON to write a data signal to the storage capacitor in a data write period subsequent to the threshold compensation period,
• wherein a pulse width of the control signal pulses is twice or more as long as the data write period, and
• wherein the driver circuit is configured to:
• control the first transistor with a first control signal pulse;
• control the second transistor with a second control signal pulse different from the first control signal pulse;
• turn ON the first transistor with a start edge of the first control signal pulse before the data write period starts;
• maintain the first transistor to be ON and turn ON the second transistor with a start edge of the second control signal pulse to start the data write period after the threshold compensation period ends;
• and
• turn OFF the first transistor with an end edge of the first control signal pulse to end the data write period.
