Tεχνολογία Quattron... Και το τρίγωνο, γίνεται πεντάγωνο... :flipout: :flipout:
For the last couple of years, Sharp has been producing LCD televisions that are sometimes decent, if unremarkable. The company is aggressively pushing “Quattron” technology, seemingly in an attempt to give it the edge against the scores of incredibly similar LCD HDTVs on the market. This is not the first time a company has used promises of “bright colours” to reach out to consumers, but adding the fourth yellow subpixel is the first time that anyone has done it in such a novel way.
The unfortunate truth is that widened colour gamuts have almost no real-world use in consumer TVs. Playing back content designed to be viewed with one colour gamut (HDTV Rec.709) on another colour gamut (Sharp’s own proprietary “Quattron” gamut) does not enhance the picture quality – in fact, it does quite the opposite. For Sharp’s impressive engineering feat to have any practical use, the company would have to get the LC46LE821E’s unique colour gamut standardised and accepted by the content production community.
Of course, none of this would matter if the Sharp LC46LE821E could still be set up to put out high quality, accurate pictures: many of the displays we rate highly have wide colour gamut modes which can be side-stepped to increase picture quality when viewing normal content. What is most surprising about the LC46LE821E is that it has difficulty in living up to some of the claims that Sharp has made of it. While their promotional material promises that “a Quattron will provide smoother colour gradations” [1] and even makes mention of “bright greens” [2], in-depth testing reveals the exact opposite situation: green is one of the colours with luminance deficiency even after calibration attempts, and highly saturated content can often produce terrible contours in the image.
That doesn’t mean that the Sharp LC46LE821E is completely without merit, though: its Greyscale and Gamma tracking (post-calibration) were both absolutely excellent, and when the aforementioned colour problems weren’t getting in the way, these traits could produce a fairly high quality viewing experience. In fact, even although there are better displays out there in terms of accurate colour, when the “colour contouring” flaw wasn’t visible, the colour reproduction was satisfying (albeit slightly “off”) up to a point. Also, the measured black level of 0.05 cd/m2 is nothing to sniff at, and the low amount of input lag (19ms) makes this the best LCD TV for gaming that we’ve reviewed lately.
As it stands right now, the LC46LE821E is another Sharp display which combines some strong points with a few negatives. Sadly, the overall package is just not hugely compelling — especially given the existence of cheaper, superior alternatives.
