Abstract
A screen driver for a liquid crystal display screen includes an internal animation circuit for displacing data on a screen. The animation circuit also process data, such as modifying data between a source address and a destination address of a RAM memory. The RAM memory contains a screen memory and a buffer memory. The internal animation circuit allows relief of an external central microprocessor of equipment having the liquid crystal display screen from corresponding processes. Further, the number of data exchanges between the microprocessor and the screen driver is reduced and thus the power consumption of the equipment caused by the screen animations is also reduced.
