Abstract
A display apparatus includes a timing controller, a column driver, a row driver and a display unit. The timing controller outputs a first column clock embedded into image data during an active period, and outputs a second column clock embedded into blank data during a blank period. The column driver detects the first column clock and the image data and converts the image data into a first analog signal using the first column clock, and detects the second column clock and the blank data and converts the blank data into a second analog signal using the second column clock. The first column clock has a voltage level greater than a voltage level of the image data. The second column clock is embedded into the blank data and has a voltage level substantially the same as the voltage level of the image data.
