| 摘要 |
A flat-panel display device is disclosed which comprises m column electrodes, n row electrodes, a column electrode driver for driving the m column electrodes in response to pixel data, and a row electrode driver for driving the n row electrodes by a one-line-at-a-time scanning methode, the column electrode driver comprising a detector for checking whether or not the number of turned-on column electrodes among the m column electrodes is greater than a predetermined number and an on-time varying unit for shortening the on-time of the column electrodes in response to the output of the detector. The device has an effect of reducing power consumed by varying the on-time of the electrodes when more than the predetermined number of pixels are on. |
