AU Optronics / BenQ Introduce BFI TechnologyAU Optronics are also working on a responsiveness improvement for their panels and this is based on a different principle. Since the human brain keeps images in memory, TFT's can sometimes give the perception of afterglow even if complex equipment doesn't detect it. This is why you can't always trust response time measurements, and real life performance can vary greatly from measured figures.
By inserting a black frame every size images AU Optronics claim this helps "clean" the human eye from this perceived afterglow and have named this technology, BFI (Black Frame Insertion). This is a part of their Advanced Motion Accelerator (AMA) technology. BeHardware saw the new BenQ FP241W (left) in action at CEBIT compared side by side with a current 23" model (BenQ FP231W, 16ms S-IPS model) without this technology. They report that this is even more of an improvement than Samsung's MPA techniques, and responsiveness is apparently improved to the levels of plasma displays. Again, the fact that this is in clone mode with a relatively slow model like the FP231W shows that for exhibition purposes, this improvement is likely to be exaggerated. Fortunately, new models will begin to emerge in June 2006 according to BenQ. They released this press statement recently about the forthcoming FP241W: "The BenQ FP241W (BFI) wide-screen LCD monitor features the world-leading BFI technology, a high resolution of 1920x1200 and HDMI connector. The world-leading BFI (Black Frame Insertion) Technology is the advanced technology of Advanced Motion Accelerator (AMA) Technology. By using BFI Technology, the spatial-temporal integration can effectively reduce the ghosting effect caused by the slow pursuit and low pass effect of the human eyes thus provides clearer motion pictures. The FP241W is the first monitor of its kind with a HDMI connector worldwide. HDMI (High Definition Multimedia Interface) TM technology is the latest digital technology to connect set top box such as TV, PS2, Xbox, in an efficient and easy way whilst carrying HD audio and video signals in one single cable." Samsung Unveils Their First LED Backlit Displays
Rather than using traditional CCFL backlighting, Samsung have introduced a few new models which will feature LED backlights. The marketing behind these new models will likely be based around the improved uniformity and colour gamut that this technology can offer over conventional models.

LG Emotional L1900 Series and Digital fine Contrast No new technologies really from LG other than using LG.Philip's Digital Fine Contrast in some of their new models. Instead they unveiled a few new designs which may be to some people's taste, but not to others. Images again courtesy of BeHardware and Flatpanels.dk. The Euro L1900 Series monitors. There are 3 different designs for this L1900 range, and early released specs suggest that they will be TN Film panels, rated at 4 ms, with 1600:1 contrast ratio (DFC) and with 300 cd/m2 brightness. The 3 different varieties are Celadon, Myth and Breath according to BeHardware, but as you can see from the spec, LG refer to them as Jar, Ring and Eclipse. I have matched up which one is which, but am not 100% sure of the LG naming, I've gone with what seems most logical:
