The electrooptical display apparatus includes pixels, and scan lines and data lines arranged in a matrix. The apparatus further includes pixel switching elements each enabling, in response to application of a selection voltage to one scan line, application of a pixel voltage to one pixel in a pixel row corresponding to the one scan line through one data line, a voltage producing part producing a sampling voltage that is to be supplied to the data lines and that monotonously changes while the selection voltage is applied to the scan line, a voltage sampling part sampling the pixel voltage from the sampling voltage, a sampling number detecting part detecting number of pixels for which a same voltage is sampled, and a controller lowering a frequency of sampling of the pixel voltage when the detected number is a predetermined number. |
