An apparatus for improving an image-sticking effect of a liquid crystal display is described. The apparatus has a comparator, a counter connected to the comparator, and an inset device connected to the counter. When receiving an image datum, the comparator first compares the image datum with a previous image datum stored in an image memory to determine whether the image datum is a still image or not. If the image datum is not a still image, the image datum is directly transmitted to an image output device. On the contrary, if the image datum is a still image, a value of the counter is then increased. An inset image is produced by the inset device and is transmitted to the image output device when the value equals a threshold value. As a result, the image-sticking effect is reduced because an image that is still for a long period is forced to change.
