Electronic device and method capable of reducing afterimage of display

An electronic device comprising:

• a housing;
• a display in which a display panel including a plurality of pixels is divided into a first area and a second area;
• a display driver integrated circuit (DDI) for driving the display panel;
• and
• at least one processor,
• wherein each of the plurality of pixels comprises:
• a first thin film transistor (TFT),
• a second TFT for switching a connection between a data line of the display panel to which a data voltage is supplied and a source of the first TFT based on a first gate signal,
• a third TFT for switching a connection between a gate of the first TFT and a drain of the first TFT based on a second gate signal,
• a fourth TFT supplying a first initialization voltage to the gate of the first TFT based on a third gate signal,
• a fifth TFT for switching a connection between a positive driving voltage line of the display panel to which a positive driving voltage is supplied and the source of the first TFT based on a light emission signal,
• a sixth TFT connecting the drain of the first TFT and an anode of an organic light emitting diode (OLED) based on the light emission signal,
• a seventh TFT supplying a second initialization voltage to the anode of the OLED based on a fourth gate signal, and
• a storage capacitor disposed between the gate of the first TFT and the positive driving voltage line,
• wherein the at least one processor controls:
• the display panel to be in a partial display state in which the first area is deactivated and the second area is activated in response to a specified event,
• first pixels corresponding to the first area by dividing each frame into a first sub-period and a second sub-period while the display panel is controlled to be in the partial display state,
• the first pixels to receive a data voltage corresponding to an inactive state through the second TFT by supplying the first gate signal to the first pixels in the first sub-period, and
• the first pixels to receive a bias voltage through the second TFT by supplying the first gate signal to the first pixels in the second sub-period, and
• wherein the first pixels maintain the first TFT in a bias state by receiving the bias voltage in the second sub-period.
