摘要：
Displaying the images encoded in a display signal which also contains synchronization signals and display enable (DE) signal. The DE signal indicates the time points at which the display data portion of the display signal contains active pixel data elements representing image frames. A display unit generates HDISP and VDISP signals (indicative of the active time in which active pixels and lines are respectively received) based on the DE signal. As the DE signal generally tracks (in the time domain) the active pixel data elements, the active pixel data elements forming image frames are accurately identified, and a superior image quality generally results.
