摘要： The present invention provides a marking apparatus for a display panel and a marking method for a display panel. The marking device comprises an image acquiring module, a simulated marking module and a real marking module. A simulated marking line is drawn, by the simulated marking module, in an image acquired by the image acquiring module, of a region containing a position where a defect occurs on a display panel to be marked. The real marking module automatically draws a real marking line on the display panel to be marked according to the simulated marking line. Thus, a position where a defect occurs on a display panel to be marked is accurately marked, and it is convenient for an engineer to accurately locate and sample the defective position in the subsequent analysis process.
