Display panel with touch detection function, method of driving the same, driving circuit, and electronic unit

摘要

There are provide a display panel with a touch detection function, in which display operation is less affected by touch detection operation, a method of driving the display panel with a touch detection function, a driving circuit, and an electronic unit having the display panel with a touch detection function. The display panel with a touch detection function includes: one or more display elements; one or more drive electrodes; one or more touch detection electrodes; and a drive section selectively applying a DC drive signal or an AC drive signal to the drive electrodes.

主权项

1. A display panel with a touch detection function comprising:
one or more display elements; one or more drive electrodes; one or more touch detection electrodes; a drive section selectively applying a DC drive signal or an AC drive signal to the drive electrodes; a first wiring and a second wiring on a substrate; and one or more switch elements on the substrate, wherein
the first wiring is applied with the DC drive signal,the second wiring is applied with the AC drive signal, andthe switch element switches a drive signal, which is applied to the drive electrode, between the DC drive signal of the first wiring and the AC drive signal of the second wiring, wherein
the display elements perform a write operation for display during a write period,the AC drive signal has a pulse waveform that transitions from a first voltage to a second voltage corresponding to a DC voltage level of the DC drive signal, andthe drive section applies the AC drive signal to the drive electrodes in order to perform a touch detection drive in a period other than the write period.
