ABSTRACT:
The invention provides a semiconductor integrated circuit having a zooming function independently in a driver IC for driving a display device. The semiconductor integrated circuit can be a semiconductor integrated circuit which respectively outputs a plurality of two-dimensional images of different sizes according to a mode signal from a plurality of output terminals. It can include select signal shift circuits and the like which, in a first mode, synchronize with one of a rise-up or a fall of a clock signal and sequentially supply a select signal to each of select signal supply terminals, and, in a second mode, synchronize with the rise-up and the fall of the clock signal and sequentially supply the select signals to two of select signal supply terminals at a time. The invention can also include a first group of latch circuits and the like which hold image data in response to the select signals sequentially supplied to the select signal supply terminals, and a second group of latch circuits and the like which hold image data outputted from the first group of latch circuits in response to a line pulse.
