The equality circuit is provided to display the stable screen by equalizing the synchronizing signals of the united signal using a memory and a controller, and comprises: a synchronizing signal time difference deciding part(15) which decides asynchronism between a main and a sub synchronizing signal (HA,HV); a delay control part(52) which outputs the control signals(a,b); an image data delay part(53) which delays a sub image signal data(SV) by the amount of asynchronism; a switching controller(54); an image signal switching part(55) which selects the sub image signal data(SV)and the main image signal data(SA). |
