Most of the Refresh Rate references by TV manufacturers exist to convince buyers to get a new TV set, with different brands coming up with different terms to refer to their model's TV Refresh Rate and individual Motion Blur solution. The "Refresh Rates" you see on marketing campaigns from different brands are not complete fabrications. Each company uses a simple, though dubious, method to determine and make refresh rate claims. In order to boost their numbers, different brands use the flashing backlight and video processing to determine the "Refresh Rate." In Aroyi, we prefer the term Motion Clarity, to differentiate from the strict technival definition of Refresh Rate. Motion Clarity is manufacturer specific and some of the common "Refresh Rate" terms you will see on your favorite brands include:
LG – TruMotion
LG refers to its refresh rate as TruMotion. LG advertises TruMotion as the better option for fast-action video, with 120, 240 and 480 Hz options available on some LCD TVs. In the models available in the market, only one has a 480 Hz TruMotion. The other models are either TruMotion 120 or 240 Hz.
Panasonic – Backlight Scanning
Panasonic is open about its backlight scanning, with statements from the manufacturer claiming that the Backlight Scanning technology minimizes flicker, even in high-speed action images to give smooth viewing. The 120 Hz/240 Backlight blinking technology also promises to improve clarity, contrast, and sharpness, with virtually no image blur.
Samsung - CMR
Samsung takes a more creative marketing approach; instead of using the ‘480 Hz’ claim, they have CRM (Clear Motion Rate). The CMR takes into consideration the three basic factors that influence motion clarity namely: image processor speed, panel refresh rate and backlight technology. This means that a TV with a 240 CMR may have a 120 HZ panel, a scanning backlight and an average processor. Therefore, there is no guarantee that a TV set with a CMR of 240 could come with a 240 Hz panel.
Sharp – AquoMotion
Sharp is quite honest with its specs specification; however, their backlight scanning technology multiplies the refresh rate to give you smooth images during fast-moving action and sports. For example, AquoMotion 960 quadruples the refresh rate while the AquoMotion 480 backlight scanning technology doubles the refresh rate, which means your screen features a 240 Hz screen in both cases.
Sony – Motion Flow
Sony claims to improve picture clarity during fast action by taking the image viewing experience beyond the refresh rates by quadrupling the motion effect so that you can enjoy the action as if you were present.
Toshiba – ClearScan and ClearFrame
Toshiba’s marketing messages cover very little detail about is ClearFrame and ClearScan technology. Both the ClearFrame and ClearScan technologies improve clarity significantly, without affecting the flicker and the brightness of the image. TV lovers who prefer a film look can choose the 5:5 pull down option available with the ClearScan 240 Hz.
Vizio – SPS
Vizio’s SPS (Scenes Per Second) offers 120 Hz technology together with scanning backlight for high quality detail. This essentially means that the "240 Hz SPS" refers to a 120 Hz TV with a scanning backlight.
