CORRECTION METHOD OF DISPLAY APPARATUS AND THE DISPLAY APPARATUS

A novel correction method for a display apparatus is provided. A correction circuit of the display apparatus obtains offset corresponding to a current flowing through a second subpixel when a first subpixel is not lit. The correction circuit of the display apparatus obtains, for each pixel, correction output data, obtained by correcting, with the offset, data corresponding to a current flowing through each of the second subpixels in sequentially supplying correction video data to the first subpixels and stores the correction video data and the correction output data corresponding to the correction video data in a memory circuit. The correction circuit of the display apparatus calculates coefficients obtained when a relation between the correction video data and the correction output data corresponding to the correction video data is approximated by a quadratic expression and stores the coefficients in the memory circuit. The correction circuit of the display apparatus stores a correction table that is created on the basis of the correction output data and the coefficients, in the memory circuit. The correction circuit of the display apparatus corrects display video data in accordance with the correction table.
