The display device, luminance unevenness in a display apparatus and a method for improving improvement

The present invention relates to display technologies, and in particular relates to a display device to improve brightness unevenness, and a method for improving a display apparatus. The improved display brightness unevenness apparatus comprising: dividing means for dividing the display area into a plurality of divided regions in the scanning line direction; acquisition module, for collecting the display luminance of each divided region; comparison module, according to each of the divided acquisition display luminance region is set at a gray level of the current reference brightness; adjusting module according to the reference brightness, and the display luminance in each of the divided region of the current gradation, were adjusted for each divided area is displayed in the current grayscale brightness, reducing the difference in brightness of each divided region in the display gray scale of the current. Variation of the present invention can effectively improve the display luminance of the display device, greatly enhance the display effect device, enhance the user experience.
