A display apparatus includes a display panel, a timing control part and a data driving part. The display panel is divided into N display areas. The timing control part includes a serializing part to serializing N data received in parallel to generate an N-th frame data, a overdriving part to select one of the N-th frame data and a previous frame data stored depending on whether the received data are normal and to compensate the selected frame data to generate a compensation frame data, and an interface part to divide the compensation frame data and to output the N compensation data. A data driving part includes N data driving circuits to generate data driving voltages corresponding to the N compensation data to output the data driving voltage to the N display areas where N is a natural number.

In a liquid crystal display equipped with a timing controller, the timing controller generates a restoration signal having a predetermined pulse width in response to a data enable signal and operates in a fail mode when a difference between the data enable signal and the restoration signal is larger than a threshold value. Even if the data enable signal is distorted by electrostatic discharge, the liquid crystal display uses the restoration signal as a data enable signal without entering the fail mode when the distortion degree is smaller than the threshold value. Thus, a user may not recognize the electrostatic discharge when the electrostatic discharge is applied to the liquid crystal display for a short period of time.

A driving apparatus for a display device includes a plurality of pixels arranged in a matrix, and each pixel includes first and second sub-pixels. The driving apparatus includes a memory for storing digital data, a controller for calling the digital data to output the digital data together with a clock signal and at least one selection signal, and a gray voltage generator formed of an integrated circuit to receive the digital data from the controller and to generate gray reference voltage sets. The gray voltage generator includes first and second registers for storing the digital data, a selector including a plurality of multiplexers for receiving the outputs of the first and second registers, and a converter including a plurality of digital-analog converters connected to the multiplexers. As described above, the gray voltage generator is provided in the form of a chip so that it is possible to reduce the area occupied on a printed circuit board (PCB) and to reduce the cost of the gray voltage generator.
