A portable device which can display a television image. A first RAM is provided on an LSI processor chip of a portable phone. A processor in the LSI processor chip writes data of an odd field to the first RAM during an odd field period and reads the data from the first RAM and outputs to an LCD controller during the next even field period. A processor in the LCD controller writes data to a third RAM during the even field period and again reads the data from the third RAM and displays on an LCD panel during the next odd field period.
