Display device

摘要

To provide an active matrix display device in which power consumption of a signal line driver circuit can be suppressed, so that power consumption of the entire memory can be suppressed. A plurality of memory circuits which can write data of a video signal input to a pixel in one line period and can hold the data are provided in a signal line driver circuit of a display device. Then, the data held in each memory circuit is input to a pixel of a corresponding line as a video signal. By providing two or more memory circuits in a driver circuit, pieces of data of video signals corresponding to two or more line periods can be concurrently held in the memory circuits.

主权项

1. A display device comprising:
at least a first memory circuit configured to store lines of data of video signals corresponding to a plurality of frame periods; a data comparison circuit configured to read the lines of data of the video signals from the first memory circuit, compare the lines of data, and extract groups each including at least two lines of data corresponding to at least two different line periods in which the data of video signals correspond to each other, the at least two different line periods being non-adjacent; a pixel portion including a plurality of pixels; and a signal line driver circuit including a sampling circuit and a plurality of latch circuits each connected to the sampling circuit and configured to sequentially output the at least two lines of data of the at least two different line periods, each latch circuit being configured to concurrently hold data of video signals corresponding to one of the groups.
