<P>PROBLEM TO BE SOLVED: To provide a data driving circuit having a current storing and replicating function and containing a current storing and replicating module leading replicated current signals in a reproducing/ adjusting stage, to resolve a problem of stability in the conventional technic. <P>SOLUTION: This data driving circuit 30 includes a digital/ analog current converter 38 converting received digital signals into analog current signals; a current storing and replicating module 42 storing a schedule voltage required to lead the analog current signals in a converting/storing stage, and leading the replicated current signals into data lines in a reproducing/adjusting stage; and a control circuit electrically connected between the converter 38 and the module 42 and switching between the converting/storing stage and reproducing/adjusting stage. The replicated current signals are gray scale current signals, being almost same as the analog current signals. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
