Abstract
A parallel-to-serial signal converting apparatus which comprises: a logic circuit for converting first parallel bit signals of a low frequency to be converted to a high frequency serial bit signal into second parallel bit signals having the same frequency as the first parallel bit signals and having information as to whether adjacent two bits of the serial bit signal are equal in level or not; a circuit for adjusting the phase of the second parallel bit signals to form third parallel bit signals whose phases are shifted by a phase difference, successively, in an order of corresponding bits of the serial bit signal, the phase difference being substantially equal to the phase difference between adjacent two bits of the serial bit signal; and a logic circuit for logically processing the third parallel bit signals to obtain the serial bit signal. An image displaying system utilizes the parallel-to-serial signal converting apparatus.
