Abstract:
1. A display control device, comprising: a controller for providing a mode-control signal; a scaling engine for producing a first interface signal; a timing controller for converting said first interface signal into a second interface signal; a selector for selecting either said first interface signal or said second interface signal to serve as a reference signal for output according to said mode-control signal; and an interface circuit for converting said reference signal into an output signal according to said mode-control signal; wherein, when said mode-control signal is under a first mode, said output signal is substantially said first interface signal; when said mode-control signal is under a second mode, said output signal is substantially said second interface signal; when said mode-control signal is under a third mode, said interface circuit converts said first interface signal to a third interface signal to serve as said output signal thereof; and when said mode-control signal is under a fourth mode, said interface circuit converts said second interface signal into a fourth interface signal to serve as said output signal.
