5 Best Practices for Smartphone Support
At another Sony TV launch last month, Sony’s then new, 1st generation 200Hz Bravia was demonstated next to the earlier 100Hz model and the earlier 50Hz model before that, with the same video showing on all three screens. The 50Hz is slowly stuttering along as a video of a desk globe of the Earth spins on screen, and other “motion” footage, the 100Hz is noticeably smoother, and naturally, the 200Hz screen looks smoothest of all, with all three screens completely in sync. Now Sony boasts that its new Z5500 series, which arrives next month in a 40-inch (AUD $3499), 46-inch ($4199) and the headline 52-inch screen size ($5199), and it’s the first from Sony to offer its “2nd-gen 200Hz” system - just in time to defend against LG’s new 200Hz screens and the 600Hz plasmas from Panasonic and Samsung for the 2009 shopping season. Each company says its technology is the best. Current.com.au’s Grant Shepherd quoted Sony’s “Technology Communications Manager”, Paul Colley, explaining at the Z5500 series launch that “This new model is not just 200Hz, it’s the 2nd Generation of 200Hz, which further improves and sharpens all aspects of motion. Most 200Hz can’t handle vertical motion correctly; the new Bravia Z55 handles it perfectly.” LG’s website makes no mention of “vertical motion”, but naturally disses “other 200Hz technologies” which “use an interpolation system which creates “ new frames” between each true frame. These interpolated frames are the TV’s best guess as to what should appear" - but presumably this is referring to Sony's 1st-gen 200Hz tech. LG explains that its “TruMotion 200hz uses a different approach with frame insertion plus scanning backlight technology. By flashing on and off, the backlight produces actual black frames between true frames and inserted frames and therefore reduces motion blur, increasing sharpness and improving contrast level in dark scenes.” It'll be intersting to see the latest model of each side-by-side with the same content to compare! The plasma guys are fighting back with plasma screens offering a 600Hz "sub field drive", and this is also supposed to improve motion and picture quality. Plasma is already supposed to have much better motion quality than LCD in the first place, which is why LCDs were improved to 100Hz and then 1st-gen 200Hz in the first place, to combat plasma's superiority in that area. So plasma needs a "Hz" number too for competitive reasons, even though plasma and LCD are two different technologies. For now 600 is it, which sounds better than 200, and so the marketing and in-store sales battles continue! Debate rages on the Internet as to which is better – everyone seems to have a different opinion as to why 200Hz, 60Hz, 24p, 600Hz, Laser TV, OLED or something else is the superior viewing solution. Won’t next year offer even better screens and some new technology? Please read on to page 2. |
