    • A display device and an optical compensation method for the same are disclosed. In one aspect, the method includes displaying a test image on the display panel, wherein the display panel comprises first, second, and third areas. The method also includes photographing the first and second areas together to generate first photographed data, photographing the second and third areas together to generate second photographed data, and extracting luminance data from each of the first and second photographed data. The method further includes respectively applying different weights to the luminance data of the second area extracted from each of the first and second photographed data to generate compensated luminance data, and generating a compensation parameter for each pixel based at least in part on the compensated luminance data.
    • 公开了一种显示装置及其光学补偿方法。 一方面,该方法包括在显示面板上显示测试图像,其中显示面板包括第一,第二和第三区域。 该方法还包括将第一和第二区域一起拍摄以产生第一拍摄数据,一起拍摄第二和第三区域以产生第二拍摄数据,以及从第一和第二拍摄数据中的每一个提取亮度数据。 该方法还包括分别对从第一和第二拍摄数据中的每一个提取的第二区域的亮度数据应用不同的权重,以产生补偿的亮度数据,并且至少部分地基于经补偿的亮度数据产生每个像素的补偿参数 。
