US Patent 11106302 Display device and electronic apparatus

A display device with a touch detection function is provided and includes a substrate; pixel electrodes including first and second pixel electrodes; drive electrodes including first and second drive electrodes; a display function layer that exerts an image display function based on a pixel signal; a drive electrode driver configured to apply a touch driving signal for touch detection or a common signal for display to the respective drive electrodes; and a source driver configured to apply the pixel signal to the respective pixel electrodes, wherein when the pixel and common signals are provided, the second pixel electrode is in a floating state and the touch driving signal is provided to the second drive electrode, thereby enabling image display function on a first sub-pixel corresponding to first pixel and drive electrodes and touch detection function on a second sub-pixel corresponding to second pixel and drive electrodes to occur concurrently.
