How 100Hz originally worked
A acceptable Pal television will refresh the photo 50 times per second or at a frequency of 50Hz. The Frames Per Second (Fps) are the quantity of frames needed to generate the illusion of motion. Our eyes are often aware of this frequency depending on the speed of the image, the intensity of darkness, and the intensity of brightness accordingly you will on occasion notice the photo flicker on a 50Hz Television. Moreover the bigger the screen is the more apparent the flicker is.
Plasma Review
At 100 Fps (100Hz) Tv operates at twice the Frames Per Second by creating a double of every frame and inserting it after the old one. On a 50 Fps (50Hz) Cathode Ray Television (Crt) because the photo is created by an expensed particle scan there is a descriptive flicker that can be seen by the human eye. As a succeed of doubling the scan frequency to 100Fps and inserting a copy frame this question is not apparent as far as the human eye is concerned. The succeed of this is to appreciably sacrifice the flicker.
The benefit of 100Hz on plasma and Lcd Tv's
plasma and Lcd televisions don't have flickering because they don't generate the photo with an electron scan. Any way Lcd and plasma Tvs still gain from 100 Herts because developed digital circuitry creates an supplementary frame or middle image. The Television does this by creating an supplementary frame by means of complex interpolation, as well as appeal compensation calculations to fancy what the increasing fields and frames look like, instead of inserting a copy frame. (e.g. The first and second frames are different).
Nevertheless even at 100Hz the photo still does not furnish a thoroughly level photo especially with fast appeal images. Several television industry effort to sacrifice this supplementary by using digital photo processing. Typically there is still a exiguous obscuring on quick intelligent images although the advantages are clearer and better-defined surfaces, smoother movement, and sharper pictures than is possible from 50 Frames Per Second Lcd Tvs and PlasmaTvs.
For example if a football moves ten pixels from left to right in the middle of frames one, two and three, the 100Hz television will digitally make two added frames in the middle of one and two, along with two and three, in which the ball will move five pixels. This results in five frames in which the football moves a total of ten pixels i.e. The preliminary frames one, two and three plus the digitally created frames inserted in the middle of one and two, and in in the middle of two and three. The succeed of this is that the eye sees an image that moves more smoothly than previously.
The benefit is that 100Hz televisions have a clear benefit of ending the majority ghosting effects now and then seen in Lcd Tvs. The ghosting succeed caused by the subsequent image being displayed before the preceding one has faded away.
Most top manufacturers have got 100Hz Plasma and Lcd televisions including Jvc, Panasonic, Toshiba, Samsung, Lg, Sony, Philips,Hitachi and Pioneer.
Further advantages with 200Hz
A range of 200 hertz televisions have been produced by Sony which digitally inserts three supplementary frames in in the middle of the original 50Hz frames. Thus rapidly intelligent scenes are seen with a smoother, more fluid and sharper photo than 50Hz or even 100 hertz televisions.
Benefits for habitancy who have photosensitive epilepsy
Research has shown that 100Hz Tv's can aid in preventing seizures in habitancy who suffer with photosensitive epilepsies when viewing television or playing computer games.
