Liquid cristal display for laser marker |
摘要 |
<p>A liquid crystal display for a laser marker in which row and column electrodes are provided for each of pixels of a liquid crystal, the row and column electrodes are grounded and then predetermined effective voltages are applied to the row and column electrodes to perform switching of display of a liquid crystal display screen. Effective voltages larger than the predetermined effective voltages are applied to the electrodes only for a predetermined period of time after starting application of the voltages to the electrodes and the predetermined effective voltages are applied to the electrodes after passage of the predetermined period of time. <IMAGE></p> |
