    Abstract: A timing controller includes a count control circuit, a pulse width detector, and a pulse generator. The count control circuit receives an external enable signal. Pulses of the external enable signal include an effective and a blank period of image data. The count control circuit counts pulse widths of each of the pulses. The pulse width detector receives the counted pulse widths, compares a pulse width of a present pulse with pulse widths of previous pulses, and detects a pulse width of a previous pulse that has a pulse width smaller than the pulse width of the present pulse. The pulse generator generates three output pulses having pulse widths that are one-third a period of the detected previous pulse. The pulse generator outputs the first, second and third pulses as an internal enable signal.

    Abstract: A signal controlling method for a display device for signal processing between an external system and a display panel that displays an image by receiving a signal from the external system. The method includes receiving N clock signals and N data signals synchronized with the N clock signals from the external system through N channels, N being a natural number no less than 2; writing the received N data signals in N storage units in order of reception time of the N data signals; extracting one clock signal from the N clock signals; and outputting the N data signals written in the N storage units simultaneously in synchronization with the extracted clock signal.

    Abstract: A timing controller includes a plurality of image enhancement blocks, a plurality of dithering blocks and a random number generating block. The plurality of image enhancement blocks performs image quality enhancement operations for input image data. The plurality of dithering blocks performs random dithering operations for outputs of the plurality of image enhancement blocks based on a plurality of random number tables. The random number generating block generates the plurality of random number tables which is provided to the plurality of dithering blocks.
