    摘要: A controller-driver, a method of driving the controller-driver, and a method of processing image data enabling scroll or other various functions without adding a storage capacity of a display memory nor increasing power consumption. A built-in display memory having a capacity of one frame (H pixels×V pixels×the number of bits) is partitioned into a plurality of memories according to an image type. High order bits are then stored in a first display memory 7a and high order bits of the next frame or low order bits are stored in a second display memory 7b by using a first selector 8 to a third selector 10 controlled by a memory control circuit 6 before they are read out. Thereby, high-level image data of one frame can be displayed when the scroll function is not used and image data of a plurality of frames can be displayed without accessing an image drawing unit 1 when the scroll function is used, thereby reducing power consumption.

    摘要: A display memory circuit includes a drawing memory and a dynamic display memory. The drawing memory stores data and at least a portion of the data are possibly rewritten into a new data at a third timing, the third timing being optional between a first timing and a second timing. The dynamic display memory is connected with the drawing memory, which latches the data in response to the first timing and continues to hold the data between the first timing and the second timing. The drawing memory is partially disconnected from the dynamic display memory in the rewritten portion when the portion is rewritten in the drawing memory.
