Abstract: An apparatus and a method that quickly detect an error that may occur due to an external noise occurrence during display of image data on a screen of an image display device, and that control a strobe signal output to prevent a screen defect from being displayed on the display device screen.

Abstract: The present examples relate to a liquid crystal display device with a repair function. The present examples repair a defect of a line or a defect of a pixel, using a specialized data signal structure, wherein the data signal structure integrates channel data, which is required for channel driving of a liquid crystal display element, and repair amplifier data, which is used for repairing a defect of a line and/or a pixel. Thus, examples have a better repair function than an alternative liquid crystal display device.
