So I guess I have to conclude that what has always attracted me to Sharp is their product design, rather than their engineering quality.
But I just saw a banner ad for what Sharp has branded “Quattron quad pixel Technology” (complete with random capitalization), and I have to say this is one of the dumbest, least sharp ideas I’ve ever seen.
The new technology adds a yellow (Y) channel to the existing red (R), green (G), and blue (B) transmissive primaries.
First of all, the claimed product benefit is richer, more vibrant colors on an LCD television screen. I don’t see a lot of benefit there. Aren’t the colors on television garish enough already?
Second, the RGB gamut encompasses Y. In terms of the physics, no new colors are being added to the gamut.
The signal sent to the television is an RGB signal. Processing it to subtract out the Y algebraically and send it to the new Y channel may or may not decrease the overall power consumption of the set at a given brightness. If it does decrease power consumption, maybe this was the reason for developing the technology. In that case, it’s a real consumer benefit and should be the one Sharp is promoting instead of the “more colors” voodoo science they’re touting.
The blurb copy on the page I linked to above is another matter altogether:
Sharp once again demonstrates its leadership in LED LCD TVs [LEDs provide the backlighting; LCDs define the colors. I had to figure this out myself after first wondering if the copywriter had any idea that these are two distinct technologies used in quite different kinds of displays. A link to an explanation would have helped.] with its groundbreaking [mind-boggling?] Quattron quad pixel Technology. For the very first time [Delete “very,” a weak modifier that adds nothing to “first,” which is an absolute.], yellow has been added to the conventional red, green and blue color filter, enabling more colors to be displayed [Not really, as explained above.]. Introducing never-before-seen colors [Never-before-seen colors? Really? Do tell.] to LCD TVs, like sparkling golds, Caribbean blues and sunflower yellows without overdriving the panel [Oh, you had a problem with the panel, whatever that is, being overdriven, whatever that means. If this knowledge is of benefit to the consumer, because, for example, it reduces power consumption (if that’s the case), then explain the benefit to the consumer. Otherwise, you’re just parroting back what some engineer told you and you don’t understand it any more than I do. In any case, it casts doubt on your selling proposition. So just delete the phrase.]. Sharp is redefining the way we see LED LCD TV.Maybe you’ve seen the cubicle placard that reads “If you can’t dazzle ’em with your brilliance, baffle ’em with your bullshit.”
Honesty matters. Honest. It does.
