Samsung, Sony, LG and Vizio offer or will offer HDTVs with LED backlights, the most effective picture quality improvement available for LCD TVs, and now Toshiba will too.
The SV670 series includes two screen sizes, the 46-inch 46SV760U and the 55-inch 55SV760U, and will be available in May (prices were not announced).
The company was quick to stipulate that the sets’ LEDs employ “local dimming” technology, which can dim and turn off sections of the backlight while leaving others bright as needed. Other LED models with local dimming we’ve reviewed in the past, from Samsung and Sony, delivered deeper black levels and better overall picture quality than standard LCD TVs.
As with many other higher-end models announced at CES this year, the SV670 series also boasts 240Hz refresh rates–although we appreciated that the company called it a “240Hz effect” to be extra-careful. Compared to 120Hz models, the company claims that 240Hz delivers smoother images with less blurring–although if our review of the Sony KDL-52XBR7 is any indication, the difference will be difficult to discern.
Like LG and Vizio, Toshiba’s 240Hz sets use the scanning backlight version of 240Hz, which turns the backlight on and off very rapidly. Sony and Samsung use a different version of 240Hz, which interpolates three extra frames for every true frame. We doubt many viewers will be able to tell the difference, but we’ll wait till we can compare the two 240Hz methods.
