<p>A liquid crystal display for a laser marker for attaining a higher marking speed, characterized in that a liquid crystal display screen (10) is divided into a first zone (10a) where a sub-scanning is first performed and a second zone (10b) where a sub-scanning is performed following the first zone (10a) sub-scanning, that switching of display is performed independently for each of the first and second zones (10a,10b), and predetermined voltages are applied, respectively, to row and column electrodes after those row and column electrodes are grounded, whereby display switching processing can be performed independently for each of the first and second zones. Completion of the sub-scanning of the first zone (10a) is detected by a position detecting means, and when such a detection is done, switching of display in the first zone (10a) is independently performed. In addition, when the position detecting means detects the completion of sub-scanning of the second zone (10b), switching of display in the second zone (10b) is performed independently. <IMAGE></p> |
