Display device and method for controlling display device

A display apparatus that includes a display panel in which a plurality of pixels are arranged in a matrix and a drive section that drives the display panel based on an input signal, the display apparatus comprising:

• a conversion section configured to convert, for at least one of the pixels, an original signal indicating a luminance into either or both a bright signal and a dark signal, the bright signal indicating a luminance brighter than the luminance indicated by the original signal, the dark signal indicating a luminance darker than the luminance indicated by the original signal;
• a calculation section configured to calculate a luminance difference between an original signal for one pixel unit and an original signal for another pixel unit, the one pixel unit including at least one pixel among the pixels, the other pixel unit being located adjacent to the one pixel unit and including at least one pixel other than the at least one pixel included in the one pixel unit among the pixels;
• a determination section configured to determine whether or not the luminance difference calculated by the calculation section exceeds a threshold value;
• a selection section configured to select the original signal for the one pixel unit when the determination section determines that the luminance difference exceeds the threshold value, and to select the bright signal or the dark signal for the one pixel unit when the determination section determines that the luminance difference does not exceed the threshold value;
• and
• an input section configured to input to the drive section the input signal based on a signal selected by the selection section.
