摘要: A control method and a display apparatus are provided. The control method includes dividing a display part into sections; detecting output luminance levels which correspond to grayscale levels of an input video signal on a section by section basis; converting the output luminance levels by calculating calibration coefficients on a section by section basis and applying the calculated calibration coefficients to the respective detected output luminance levels to control respective maximum luminance levels of the detected output luminance levels to be a permitted luminance level; and setting up a calibration table based on the respective converted luminance levels and a reference luminance level. The display apparatus includes a display part which comprises a plurality of sections; a signal processing part; and a controller which detects output luminance levels on a section by section basis, converts the output luminance levels, and sets up a calibration table.
