Patent Number: 7,355,534

Title: Serial-to-parallel conversion circuit, and semiconductor display device employing the same

Abstract: In a serial-to-parallel conversion (SPC) circuit for digital data which converts the digital data serially inputted, into parallel digital data, and which outputs the parallel digital data; clock signals at frequencies which are, at the highest, 1/2 of the frequency of the input digital data are employed for operating the SPC circuit, whereby the SPC circuit is improved in power dissipation, stability and reliability.
