Abstract: A display apparatus includes: a display panel including a plurality of pixels and a panel driver for applying a data voltage to pixels by the same pixel-column and performing a sensing operation, which senses the pixels receiving the data voltage. The plurality of pixels include first pixels having a first color and second pixels having a second color different from the first color. After the sensing operation is performed on a first odd-numbered group of the first pixels, the sensing operation is performed on a first even-numbered group of the first pixels. After the sensing operation is performed on the first even-numbered group of the first pixels, the sensing operation is performed on a second odd-numbered group of the second pixels. After the sensing operation is performed on the second odd-numbered group, the sensing operation is performed on a second even-numbered group of the second pixels.

Abstract: A driving controller set includes a net power control setter, a data clamper, a data line, and a data driver. The net power control setter may determine a first scale factor for adjusting a grayscale value of (N+1)-th frame data based on a load of N-th frame data and a net power control reference value. N is an integer equal to or greater than two. The data clamper may determine a second scale factor for adjusting a grayscale value of the N-th frame data based on a load of (N−1)-th frame data and the N-th frame data. A data signal may be generated using the first scale factor and/or the second scale factor. The data line may include a conductive material. The data driver may convert the data signal into a data voltage and may output the data voltage to the data line.

Abstract: A display apparatus may count a number of frames and adjust a cycle of clock training operations depending on a frame count number in a data-sensing driver to prevent or reduce unnecessary clock training operations. The data-sensing driver may perform more sensing operations by increasing the number of sensing operations and reducing the number of clock training operations. As a result, the data-sensing driver can quickly sense deterioration of a display panel of the display apparatus, and prevent or reduce a momentary afterimage, thereby improving a display quality.
