Abstract:
1. A display apparatus comprising: a timing controller which outputs image data and a first column clock during an active period, the first column clock being embedded into the image data and having a voltage level greater than a voltage level of the image data, and which outputs blank data and a second column clock during a blank period, the second column clock being embedded into the blank data and having a voltage level which is substantially equal to the voltage level of the image data; a column driver which detects the first column clock and the image data during the active period and converts the image data into a first analog signal using the first column clock, and which detects the second column clock and the blank data during the blank period and converts the blank data into a second analog signal using the second column clock; a row driver which outputs a scan signal based on a control signal received from the timing controller; and a display unit which displays an image based on the first analog signal, and which displays a black image thereon based on the second analog signal.
