Overview: Motion on a display
Motion on a display depends on presentation cadence, pixel transitions and optional visibility-control techniques.
Judder describes a timing experience; response time describes a transition; black-frame insertion changes when the picture is visible. Refresh and synchronization govern another part of that motion path. This branch gives those effects distinct explanations so several forms of blur or unevenness are not merged into one symptom.
Refresh and synchronization
Refresh and synchronization connect frame presentation to a display's update schedule.Judder
Judder is perceived uneven movement associated with irregular picture presentation durations or cadence, distinct from pixel-transition blur.Display response time
Display response time measures a defined transition in pixel output, while motion clarity also depends on picture timing, illumination persistence and processing.Black-frame insertion
Black-frame insertion or timed dark intervals reduce visible picture persistence by interrupting illumination between presentations.
