Abstract: A display apparatus including a classifier configured to classify image data into preset data of an n-bits (“n” is a natural number), a toggle counter configured to count a number of toggles based on preset data of a present horizontal line and a previous horizontal line and to calculate a final toggle number using a weighted values corresponding to a swing width between data voltages of the present and previous horizontal lines, a determiner configured to determine a representative toggle number of a present frame based on a plurality of final toggle numbers of the present frame, compare the representative toggle number with a plurality of threshold values and determine a level of a power control signal based on a compared result.

Abstract: A liquid crystal display includes a display panel, a timing controller, a gate driver, and a data driver. The display panel includes a plurality of pixels. The timing controller receives an image data, compares a previous line data with a present line data to determine whether the present line data needs to be compensated, and generates a first modulation line data. In addition, the timing controller calculates the first modulation data and a delay compensation value to generate a second modulation line data. The delay compensation value is decided from reference delay compensation values of reference pixels among the pixels.

Abstract translation: 液晶显示器包括显示面板，定时控制器，门驱动器和数据驱动器。 显示面板包括多个像素。 定时控制器接收图像数据，将前一行数据与当前行数据进行比较，以确定是否需要补偿当前行数据，并生成第一调制行数据。 此外，定时控制器计算第一调制数据和延迟补偿值以产生第二调制线数据。 延迟补偿值由像素中的参考像素的参考延迟补偿值决定。
