Samsung is at the IFA 2009 trade show in Berlin, a 400/480 Hz LCD TV presenting. Samsung said to be in this device combines the current 200Hz interpolation technique to insert black frames, a technique that BFI / DFI is called. The report comes from FlatPanelHD’s inside sources, who say the model on display will be a prototype, one step above Samsung’s existing 200/240 Hz B8000 LED TVs. According this source the new Samsung LCD TV using a technique where black frames between the original images of a 50Hz signal is attached. This black images are displayed very briefly and as objective a view to ‘reset’, the viewer’s perception of a smoother picture. This technique is BFI / DFI and is in the past for LCD monitors used.
The higher the refresh rate, the less blurry the image becomes, thanks in part to advanced interpolation methods that frequently accompany high-end sets. To aid the transition between each frame of video, these methods repeat existing frames or create new ones. Samsung’s 480 Hz LCD will use “Black/Dark Frame Insertion,” creating an extremely brief dark flash during the interpolation that “resets” the human eye. It isn’t known whether the 400Hz TV that Samsung at the IFA 2009 trade show in Berlin will show in production is taken: it is possible that only a prototype used to demonstrate the new technology. The IFA exhibition will be held from 4 to 9 September. [via FlatPanelsHD]
