Patent ID: 7049983

Claim:
A display device comprising: an insulating substrate; a pixel comprising: a pixel thin film transistor over the insulating substrate; and a display element electrically connected to the pixel thin film transistor; a gate driver electrically connected to the pixel thin film transistor; a source driver electrically connected to the pixel thin film transistor; and a serial-to-parallel conversion circuit for digital data, electrically connected to the source driver, wherein the serial-to-parallel conversion circuit converts digital data inputted serially at m Hz into 2 y parallel digital data of (m·2 −y ) Hz and outputs the 2 y parallel digital data, where letter m denotes a positive number and letter y denotes a natural number; wherein the serial-to-parallel conversion circuit for digital data operates with a plurality of clock signals of, at the highest, (m/2) Hz, and wherein the serial-to-parallel conversion circuit comprises a thin film transistor over the insulating substrate.
