DISPLAY DEVICE EQUIPPED WITH INPUT SENSOR AND CONTROL METHOD OF DISPLAY DEVICE

摘要

According to one embodiment, the display device includes a display panel and touchsensor, the touchsensor outputs a detected signal from detection electrode. An energy saving control section sets a first period in which the detected signal is to be captured, and a second period which is a period except the first period, and controls, in the first period, at least power supply voltage of an image processing section, a panel control section and the display panel to an off-state or to a low voltage.

1. A display device equipped with an input sensor comprising:
a display panel including display element arrangement configured to display an image; an input sensor provided in the display panel, including a drive electrode and a detection electrode, and configured to output a detection signal from the detection electrode; an image processing section configured to output an image signal to be written to the display panel; a panel control section configured to output a panel drive signal used to drive the display panel; a sensor driver configured to output a sensor drive signal used to drive the input sensor; an internal power supply circuit configured to output a power supply voltage to be supplied to each of the image processing section, the panel control section, the display panel, and the sensor driver; and an energy saving control section configured to set a first period in which the detection signal is to be captured from the detection electrode of the input sensor, and a second period including a zero period except the first period, and control, in the first period, at least the power supply voltage of the image processing section, and the panel control section, and the power supply voltage to be supplied from the internal power supply circuit to the display panel to an off-state or to a low voltage.
