Abstract
According to an aspect, a display device includes: a display section that has a first period to consume predetermined power and a second period to consume less power than in the first period, and power consumption of which periodically changes by repeating the first period and the second period; a smoothing capacitor that stabilizes power supplied to the display section; and a power consumption unit that consumes the supplied power in the second period.
Claims17
A display device comprising:
- a display section that includes a display unit and a touch detection device, the touch detection device incorporated in the display unit in an integrated manner, that has a display operation period to perform a display operation and a touch detection period to perform a touch detection operation, and power consumption of which periodically changes by repeating the display operation period and the touch detection period by a time-divisionally multiplexed method;
- a power supply circuit that supplies power to the display section via a driver for driving display elements of the display section;
- a smoothing capacitor that stabilizes power supplied to the driver;
- and
- a power consumption unit that consumes power in the power supply circuit in the touch detection period.
