Abstract: A display apparatus and a method for controlling the same are provided to update data effectively, such as a look-up table, by varying a communication mode of a timing controller. In a controlling method of a display apparatus(110) including a memory(130) stored data and a timing controller(120), the data is stored in a data address of the timing controller. The communication mode of the timing controller is transferred from a master mode to a slave mode. New data corresponding to the data is stored in the timing controller. The timing controller inputs and outputs data using an I2C(Inter-Integrated Circuit) communication scheme. The data includes a look-up table. When the data is stored in the data address, the timing controller stores the look-up table at a look-up table address.

A display device includes a motion estimator(133), a compensation controller(131), a compensator(137), and a display panel.

Abstract: An LCD(Liquid Crystal Display) is provided to prevent a blurring state in a moving picture and a flicker state in a still image through an impulsive operation when an image signal is about the moving picture and to compensate for brightness by increasing gray voltage in case the impulsive operation is drived. An LCD comprises a plurality of pixels(PX), a gate driver(400), a signal controller, and a data driver(500). The gate driver supplies gate signals to the pixels. If two consecutive frame image signals are inputted, the signal controller judges whether the inputted signals are about a moving picture or a still image. If the inputted signals are about a moving picture, the signal control part outputs an image signal for the moving picture and a black signal for black. The data driver(500) receives the image signal and the black signal, respectively converts them into data voltage, and supplies it to the pixels.
