A static display means that the segment or pixel is on 100% of the time or off 100% of the time. This produces a sharper contrast, but requires one control pin per segment/pixel.

A Dynamic display refreshes the segments/icons and needs less control pins, but does not product as sharp of contrast.

A segment LCD https://focuslcds.com/segment-lcd/can be segment (1:1) or Dynamic (4:1)
