A display device disclosed includes a liquid crystal panel (), and an image optimization circuit () for switching, in accordance with an update frequency of image data, between (i) a first mode in which a liquid crystal driver () is driven at a first driving frequency and (ii) a second mode in which the liquid crystal driver () is driven at a second driving frequency lower than the first driving frequency. The display device can therefore be used even in a case where a transmission path for image data is limited and optimally display high-resolution image data with reduced electric power consumption.

Display device and electronic device

A touch panel driving device includes: a noise detection section () that detects the presence or absence of at least external noise of an input operation performed on a touch panel (); and a liquid crystal drive parameter setting section () that, in a case where the presence of external noise has been detected by the noise detection section (), executes a process for reducing the external noise by adjusting a cycle or duration of a 1H period.
