Serial-Parallel Conversion Circuit, Method for Driving the Same, Display Device, and Semiconductor Device

摘要

A serial-parallel conversion circuit for converting a high-speed serial signal to a parallel signal is provided. Further, a display device with high image quality and fewer external connection terminals is provided. Furthermore, a method for driving a serial-parallel conversion circuit for converting a high-speed serial signal to a parallel signal is provided. A serial-parallel conversion circuit includes a plurality of units in each of which a sampling switch and an amplifier are connected to each other. In the serial-parallel conversion circuit, each sampling switch is configured to output part of a serial signal to its respective amplifier only through one transistor.
