Abstract
There are provided a display panel with a touch detection function and a method of driving the same, a drive circuit, as well as an electronic unit, which make it possible to reduce an influence of a disturbance noise. The display panel includes: a signal generation section selecting one pulse period from a plurality of pulse periods prepared beforehand, and generating a synchronization signal including a series of pulses appearing at the selected pulse period; a display section performing display based on the synchronization signal; and a touch detection section performing touch detection operation based on the synchronization signal.
