Patent ID: 8643583

Claim:
A display device comprising: a pixel portion including a plurality of pixels; and a signal line driver circuit comprising a sampling circuit, a first latch circuit, and a second latch circuit, the first latch circuit and the second latch circuit being connected to an output of the sampling circuit, wherein the signal line driver circuit includes a memory circuit configured to hold, concurrently and in the first latch circuit, identical pieces of data of video signals corresponding to a first and a third non-adjacent line periods while writing in the second latch circuit different pieces of data of video signals corresponding to a second line period located between the first and the third line periods, wherein the signal line driver circuit is configured to input into the pixel portion the identical pieces of data for the first line period from the first latch circuit, the different pieces of data for the second line period from the second latch circuit, and the identical pieces of data for third line period from the first latch circuit, sequentially and in this order, wherein the sampling circuit is configured to sample video signals and to input sampled video signals into the first latch circuit and the second latch circuit.
