Morphology
The components 'dual' (two) and 'display' (screen) make clear that this refers to a screen involving two scans, so there is partial compositionality. However, the technical sense of 'scan' in display-refresh technology and the specific operation (refreshing top and bottom halves simultaneously) are specialized and not predictable for a B1 learner, so full comprehension would likely require prior exposure.
Etymology
Dual scan display may come from the picture of two scans working at once: dual (two) and scan (a pass over the screen), like two people painting the top and bottom of a wall at the same time to finish faster. So the name means a screen split into two parts that are 'updated' at the same time to make the display work better.
