| 摘要 | A display signal drive circuit is configured to output a display signal having a signal level based on a common voltage to a display panel. A touch detection signal drive circuit is configured to output a touch detection signal having a signal level based on the common voltage to a touch panel in case that a composite panel is an in-cell type, and is configured to output a touch detection signal having a signal level based on a voltage level other than the common voltage to the touch panel in case that the composite panel is an on-cell type. | ||
