在加拿大

本来想买Sharp 70LE734U，Visions正好在促销，这辈子还没看过70寸的电视呢，想买回来爽爽。习惯性的上网做做功课，就同以往一样，一做就做出问题来了，本来觉得自己也多少研究过一些平板电视的原理，不敢多说大致也知道一些，今天一查发现所知甚少。。。先转一个帖子，有兴趣的可以看一下。（转）LED TVs compared: Local dimming, edge-lit, and full arrayDavid Katzmaier Senior editorJuly 7, 2010 (updated on: July 8, 2011)If you thought all LED TVs were created equal, you're underestimating the power of confusion as a marketing tool. In their continuing efforts to compete against the picture quality advantages of plasma-based flat-panel TVs, makers of LCDs TVs have introduced numerous new technologies. The most successful in our opinion is full-array LED backlighting with local dimming. When you see the words "LED TV" in an ad, it definitely refers to an LCD TV with an LED backlight, but what type of LED backlight and how it's configured make all the difference.Below we've gathered reviews of six different "LED TVs" that provide examples of all four LED backlight configurations, but first we'll provide a bit of context. All LCD-based TVs rely on a backlight of some kind to illuminate the liquid-crystal panel itself. The most common use fluorescent backlights, known as CCFL, but a growing number feature LED backlights instead. LEDs use somewhat less power, can enable thinner flat-panel cabinets, and--crucially for TV makers--provide a great excuse to charge more money. But make no mistake: despite the misleading marketing, LED TVs are just LCD TVs with fancy backlights.Unfortunately for TV shoppers, the confusion just increases from there. To help cut through the clutter we're going to lengthen our descriptions beyond the "LED TV" shorthand, and tell you how picture quality generally compares with standard LCD. More details are available in our LED TVs: 10 things you need to know companion piece as well as the individual reviews.Full-array without local dimming: The rarest of the bunch but the most familiar in concept. These models are just like standard LCD-based TVs aside from the fact that the CCFL backlight is replaced by LEDs. The "full-array" means that the LEDs themselves are arranged behind the entire LCD panel, not just along the edge.Picture quality impact: No difference compared with standard LCD.Example below: Sharp LC-70LE73U seriesEdge-lit without local dimming: The most common today. Chances are if you see an "LED TV" advertised, it's this variety, which was first widely introduced by Samsung in 2009, then imitated in the last two years by just about everyone else. It's characterized by thin cabinet designs--around just an inch or even less in depth--that lead to decreased weight in shipping and wall-mounting, along with increased bragging rights (although we fail to see much practical appeal versus a standard, 3-to-5-inch-deep flat-panel TV). Unlike full-array models, the LEDs on these sets are arranged only along the edge of the LCD panel, and can illuminate the center and other areas of the screen using so-called "light guides."Picture quality impact: No major advantage over standard LCD, and can have even more uniformity problems, such as brighter edges compared with the middle.Example below: Samsung UND6400 seriesFull-array with local dimming: The original and still the best. There are exceptions, but in general, TVs with this LED backlight configuration are the best-performing LCDs you can buy. They're similar to full-array models, but the individual zones of LEDs can be dimmed or brightened independently.Picture quality impact: Can have significantly better black levels and uniformity than normal LCD, but will also exhibit "blooming," or stray illumination, to some extent.Examples below: Vizio XVT3 series; Sony XBR-HX929 seriesEdge-lit with local dimming: A hybrid currently available on select models from Samsung, LG, and Sony. The idea is to allow some dimming of the screen in independent areas without having to place LEDs behind the LCD panel, just along the edge.Picture quality impact: In our tests of the TVs here, the Samsung achieved darker black levels than the best nondimming edge-lit model (the UND6400), and the LG matched it, but neither matched the picture quality of full-array with local dimming and both exhibited more blooming.Examples below: Samsung UND8000 series; LG LW5600 series------------------------华丽的分割线---------------------------既然买就尽可能买最好的画质咯，sony居高不下的价格就算了，可另外一个牌子是啥？Vizio？？完全没概念，放狗搜。北美（America）地区销量最好的平板电视？？没理解错北美至少应该包含加拿大吧？可是所有我知道不知道的加拿大电器店我都搜了一遍，2010年还有，到了今年反而没了？？FS，BB，Visions都搜了，没有。。。回过头来看，Sharp 的70LE734U的full array我原本以为是full array with local dimming,谁知竟然不是。当然，没有现场比较过with和without的区别，我也不敢说with一定好很多，但是从原理上讲是应该好的。随便在睡觉前发个帖子，有知道Vizio这个牌子并知道咱卡村哪里有卖这个牌子平板电视的请告知小弟一声，谢啦！呵呵

Carpe Diem vizio都是台湾的贴牌，成本比较低。点击展开...恩，其实我觉得台湾产的东西质量还可以吧，Garmin啊，一些小电器啊，很多台湾产的我觉得质量也不错，当然更不说台湾的电子制造业。现在便宜就好，呵呵，不过其实Vizio的卖点据说主要是效果好，Local Dimming有和无据说效果差别蛮大的，不知道有没有机会能看到实物比一下。
