The TV is natively only capable of displaying 120 frames per second, and basic motion interpolation which inserts between 1 and 4 new frames between existing ones. Typically the only difference from a "120 Hz" TV in this case is the addition of a strobing backlight , which flickers on and off at 240 Hz, once after every 120 Hz frame.
Recently, 240 Hz interpolation have become available, along with displays that claim an equivalence to 480 Hz or 960 Hz. Some manufacturers use a different terminology such as Samsung's "Clear Motion Rate 960" [9] instead of "Hz". This avoids incorrect usage of the "Hz" terminology, due to multiple motion blur reduction technologies in use ...
When such a movie is played on a monitor set for a typical 60 Hz refresh rate, the video player misses the monitor's deadline fairly frequently, and the interceding frames are displayed slightly faster than intended, resulting in an effect similar to judder. (See Telecine: Frame rate differences.)
In the case of filmed material, as 120 is an even multiple of 24, it is possible to present a 24 fps sequence without judder on a well-designed 120 Hz display (i.e., so-called 5-5 pulldown). If the 120 Hz rate is produced by frame-doubling a 60 fps 3:2 pulldown signal, the uneven motion could still be visible (i.e., so-called 6-4 pulldown).
The phenomenon is commonly referred to as telecine judder. Reversing the 2:3 pulldown telecine is discussed below. PAL material in which 2:3 (Euro) pulldown has been applied suffers from a similar lack of smoothness, though this effect is not usually called telecine judder. Effectively, every 12th film frame is displayed for the duration of ...
In the United States and other countries where television uses the 59.94 Hz vertical scanning frequency, video is broadcast at 29.97 frame/s. For the film's motion to be accurately rendered on the video signal, a telecine must use a technique called the 2:3 pull down (or a variant called 3:2 pull down) to convert from 24 to 29.97 frame/s.
On displays with a fixed refresh rate, a frame can only be shown on the screen at specific intervals, evenly spaced apart. If a new frame is not ready when that interval arrives, then the old frame is held on screen until the next interval (stutter) or a mixture of the old frame and the completed part of the new frame is shown ().
A curved screen is an electronic display device that, contrasting with the flat-panel display, features a concave viewing surface.Curved screen TVs were introduced to the consumer market in 2013, primarily due to the efforts of Korean companies Samsung and LG, [1] [2] while curved screen projection displays, such as the Cinerama, have existed since the 1950s.
