<p>A liquid crystal display controller (20) updates the display on a liquid crystal display panel (40) in a touch detection mode when the distance of a pointing body from a detection surface of a touch sensor (30) is equal to or less than a predetermined value, or in a proximity mode when the distance of the pointing body is greater than the predetermined value, and a coordinate calculation unit (12A) of a touch sensor controller (10) performs a detection operation with a first detection sensitivity during an update period, or with a higher sensitivity than the detection sensitivity during a pause period, thereby enhancing the detection sensitivity while reducing the influence of noise.</p> |
