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.

| 20100033453 | LIQUID CRYSTAL DISPLAY HAVING ENDURANCE AGAINST ELECTROSTATIC DISCHARGE - 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. | 02-11-2010 |
