  • Publication number: 20240138228
    Abstract: Regarding a display device (a display device including display elements driven by currents) equipped with a touch panel, degradation in display quality caused by touch is suppressed. A display device equipped with a touch panel is provided with a determination circuit (303) that determines whether or not a characteristic detection process is influenced by touch, based on a touch position and a monitoring target row which is a row to be subjected to the characteristic detection process. When the determination circuit (303) determines that the characteristic detection process is influenced by touch, a display control circuit (301) controls operation of a gate driver (12) and a source driver (20) such that a normal characteristic detection process is stopped until the determination circuit (303) determines that the characteristic detection process is not influenced by touch.
