摘要： The driving apparatus of a display device calculates a slope using a minimum gray, a maximum gray, a gray average of frame data in a current frame, and a gray average of frame data in a previous frame, and corrects and outputs the input frame data according to the slope, using frame data of one frame. As a result, a gray range of the input image signal can be extended, thereby improving visibility. Further, in a case of a motion picture, even when a difference of a gray range of images of adjacent frames is large, an original image is not distorted due to extension of a gray range. Also, even when noise is included in the input image signal, a gray range can be extended after removing the noise.
摘要翻译：显示装置的驱动装置使用当前帧中的最小灰度，最大灰度，帧数据的灰度平均值和前一帧中的帧数据的灰度平均值来计算斜率，并校正并输出输入的帧数据根据斜率，使用一帧的帧数据。结果，可以延长输入图像信号的灰度范围，从而提高可见度。此外，在运动图像的情况下，即使相邻帧的图像的灰度范围的差异大，原始图像也不会由于灰度范围的扩展而失真。此外，即使在输入图像信号中包括噪声的情况下，也可以在消除噪声之后延长灰度范围。

摘要： A gate driving circuit includes a first shift register and a second shift register for driving odd gate lines. The first shift register includes a first plurality of cascade-connected stages that sequentially output a plurality of first gate signals. A first stage of the first shift register receives a first vertical start signal. The second shift register includes a second plurality of cascade-connected stages to sequentially output a plurality of second gate signals. The first stage of the second shift register receives an output signal of the first stage of the first shift register as its vertical start signal. A data charging rate may be improved by ensuring the timing margin of each gate signal, so that the driving reliability of the gate driving circuit may be improved.
