Abstract: An organic light emitting display apparatus includes a first data line, a comparator, and a data generator. The first data line is connected to a first pixel. The comparator compares first image data of input image data to at least one of a first critical grayscale value or a second critical grayscale value, where the first image data corresponds to the first pixel. The data generator determines the first critical grayscale value or the second critical grayscale value as first corrected image data when the first image data is equal to or greater than the first critical grayscale value but lower than the second critical grayscale value.

Abstract translation: 有机发光显示装置包括第一数据线，比较器和数据发生器。 第一数据线连接到第一像素。 比较器将输入图像数据的第一图像数据与第一临界灰度值或第二临界灰度值中的至少一个进行比较，其中第一图像数据对应于第一像素。 当第一图像数据等于或大于第一临界灰度值但低于第二临界灰度值时，数据生成器将第一关键灰度值或第二关键灰度值确定为第一校正图像数据。
