Abstract: An in-cell touch panel includes a first scanning line driving circuit that supplies a display driving signal to a first scanning line group among multiple scanning lines; a second scanning line driving circuit that supplies a display driving signal to a second scanning line group among the scanning lines; a touch detection circuit that detects a touch by a pointer by acquiring a detection signal from at least a subset among multiple touch detection electrodes; and a control circuit. The control circuit performs a first scanning operation to supply the display driving signal to the first scanning line group, a touch detection operation after the first scanning operation to detect the touch with the touch detection circuit, a second scanning operation to supply the display driving signal to the second scanning line group, and the touch detection operation after the second scanning operation.

Abstract: A display apparatus includes a display panel that includes a liquid-crystal panel and a backlight arranged behind the liquid-crystal panel, and a controller that controls a luminance of the backlight and a transmittance ratio of the liquid-crystal panel. The controller is configured to: when a refresh rate at which an image is displayed on the display panel is switched, vary the luminance of the backlight such that a variation of a luminance of the display panel between before and after switching of the refresh rate falls within a predetermined range; vary the transmittance ratio of the liquid-crystal panel such that the variation of the luminance of the display panel falls within the predetermined range within a time duration that lasts until the luminance of the backlight reaches a target value; and restore the original transmittance ratio of the liquid-crystal panel after elapse of the time duration.
