摘要： A display apparatus includes a display panel, a plurality of gate lines driving circuit parts, a plurality of data lines driving circuit parts and a timing control part. The display panel includes a plurality of gate lines and a plurality of data lines. The gate lines driving circuit parts output gate signals to the gate lines. The data lines driving circuit parts output data signals to the data lines. The timing control part applies a dummy gate signal to at least one dummy gate line, controls a latch sequence of image data and an output sequence of the gate lines driving circuit parts in a reverse sequence, in response to an inverted-mounting mode selection signal for displaying an inverted mount image to the display panel. Because signal lines can be shortened, heat generated by the display apparatus may be decreased and image quality of the display apparatus may be improved.

摘要： A timing controller includes a receiver, an internal clock generator, a first frequency converter, a first selector and a control signal generator. The receiver receives an image signal and a main clock signal having a first spread spectrum frequency from an external system, converts the main clock signal to a converted main clock signal and the image signal to a first converted image signal, and outputs the converted main clock signal as a first clock signal having a plurality of frequencies. The internal clock generator multiplies the frequencies of the first clock signal and generates a second clock signal having a frequency band within the multiplied frequencies of the first clock signal. The first frequency converter converts the second clock signal to a third clock signal having a second spread spectrum frequency. The first selector selects one of the second clock signal and the third clock signal in response to a first selection signal and outputs the selected one of the second clock signal and the third clock signal as a control clock signal. The control signal generator receives the control clock signal to generate a control signal synchronized with the control clock signal.

摘要： A liquid crystal display includes a timing controller and a liquid crystal panel. The timing controller sequentially receives first through third primitive image signals and sequentially outputs first through third corrected image signals. The liquid crystal panel displays an image based on the first through third corrected image signals. The timing controller generates a first converted image signal having a first gray level based on the first primitive image signal and stores the first converted image signal. The second primitive image signal has a second gray level and the timing controller generates a second converted image signal having a third gray level higher than the second gray level when the second gray level is lower than the first gray level. The timing controller generates the third corrected image signal using the second converted image signal and the third primitive image signal.
