    Abstract: A display device is disclosed that includes pixels, a memory, and a degradation compensator. The pixels include light emitting elements. The memory is operable to store degradation information including degradation degrees of the light emitting elements. The degradation compensator is operable to receive the degradation information and generate output grayscales by changing each of input grayscales of the pixels in proportion to each of the degradation degrees. The degradation compensator includes a degradation information changer for changing the degradation information by decreasing a degradation degree having a variation greater than a threshold value among variations of the degradation degrees.

    Abstract: A display device and a method of driving the same. The display device includes a display panel including a plurality of pixels, a degradation compensator configured to output compensation data based on age values of the plurality of pixels and an input grayscale value of input image data, a scan driver configured to supply a scan signal to the display panel, and a data driver configured to supply a data signal corresponding to the compensation data to the display panel. The degradation compensator includes a first compensation unit configured to generate a first compensation grayscale value with reference to the input grayscale value and a first age value, and a second compensation unit configured to generate a second compensation grayscale value with reference to the first compensation grayscale value and the first age value.

    Abstract: A display device including: a display panel; and a signal controller which controls signals for driving the display panel, where the signal controller includes a representative value generator which sequentially operates a portion of image data of one frame, where the representative value generator moves a last position digit into another position digit of the portion of the image data and generates a representative value representing a portion of a frame image corresponding to the portion of the image data; a storage portion which stores the representative value therein; and a comparator which compares the representative values of present and prior frames to determine whether the portion of the frame image is a still image or a motion picture, and the signal controller controls the signals for driving the display panel such that a driving frequency for the still image is lower than a driving frequency for the motion picture.

    Abstract translation: 一种显示装置，包括：显示面板; 以及信号控制器，其控制用于驱动显示面板的信号，其中信号控制器包括代表值发生器，其顺序地操作一帧的图像数据的一部分，其中代表值发生器将最后位置数字移动到另一位置数位 并且生成表示对应于图像数据的一部分的帧图像的一部分的代表值; 在其中存储代表值的存储部分; 以及比较器，其比较当前帧和现有帧的代表值，以确定帧图像的部分是静止图像还是运动图像，并且信号控制器控制用于驱动显示面板的信号，使得用于 静止图像低于运动图像的驱动频率。
