这里有篇苹果新27` white led cinema display的评测，你可以看。
不过imac的27寸屏幕是不是就是这块，我不清楚:D

DELL的显示屏有声音吗？

拉线去音箱也是件非常坑爹的事情

看来更新PC台机的显示器就选这个了

主机现在有什么推荐的？

对比错误
2711才是2560*1600
当然价钱好像没差

1050刀

我擦，差点给骗了，DELL坑爹啊:D

你要这么高的分辨率做什么？:D
1050刀也才7000不到而已，坑爹什么？

我没有说我需要啊，我只不过说对比要公平啊

人家ACD什么分辨率，你也得什么分辨率，才有可比性啊

结果一比相同分辨率，DELL的这个显示器还贵了，你说的Apple显示器就是黑我不知道从何说起啊

我刚才帖的评测结论你看了没，仔细看看关于白光led背光的结论。:D

The backlight honestly takes the most getting used to. My 30-inch display is the original Apple Cinema HD display from 2004 and it used a CCFL backlight. The white LED backlit 27-inch panel just seems too cool, even when properly calibrated. The whites are very bright, but they feel a bit too harsh for me. If I dim the display then the rest of the colors get too dim as a result, I can’t seem to find a happy medium. I hear the situation is near perfect with RGB LEDs but Apple and most other manufacturers still use WLEDs for their backlights. You’ll see the impact this has on color gamut later on in the review. I spend most of my time in front of a CCFL backlit screen, but if you’re used to something LED backlit it’ll be a less of a shock.

以上出自你发的评测

我搜索到的另一段说

The ACD uses an IPS screen, where the 2709w uses a PVA screen...so the ACD will have a bit better color reproduction, but the 2709w has better contrast levels for movies and such.

看来你所谓的白光LED在对比度上有影响，然而得到了更好的色彩还原

这难道不是半斤八两吗？

你到底要说什么？请直接解释秒杀啊

白光色彩还原更好，哈哈吼。先去学习啊ccfl和white led和rbg led的区别再说吧
真不想多解释了，我承认苹果什么都是最好行了吧。:D

真觉得好笑，让你给出处，你给的这篇不给力

我自己google搜索出来的结论你又说不对

凡事有主张者自己要举证论证啊，你既然主张apple LED烂，给点论证啊

我最烦装模作样半天放不出一个屁来其实自己也是不懂装懂的了

我真不论证了，我没说过烂，只是说不值这个价，完了。
你要维护苹果产品是你的事:D
其实补点显示器知识不难的，你说是把:D

你哪只眼睛看到我维护苹果的显示器了

我只不过一直在搜索资料质疑你的结论而已，我自己可从来没下过结论，我的结论都是引用搜索结果的

你倒好，来句你不懂，DELL的就是好

这不是果青的做派吗，233

同样面板，同样分辨率的显示器 韩国的才3000元

1W买APPLE的绝对不划算

求价格链接

DELL比apple好不好我不懂，价格不比apple便宜我是搜索到了

你们别黑价格，发现黑不到，开始转移话题撒

行家你来说下DELL的1050刀的值不值那个价，别缩，说啊

苹果的不值，该卖多少，你也说下撒

我说过dell的所有型号都比水果的所有型号好？脑补莫非是你的特技？:D
我刚才已经提示你了，去查查ccfl,white led,rgb led三种背光的的区别，:D
自己不好学还要怪老师懒，这种学生我可不要

喷了，谁主张谁举证，我质疑就行，论证是你的事情，你自己没实力论证，在我看来就是一个装逼犯而已

还老师，喷了233

呵呵，如果有1000刀的预算，我选择dell 2711，绝不会是水果这台，完了。
另外说明一点，我只代表我自己。:D

别缩啊，选择是一回事情，同样的预算有人就是喜欢买垃圾货，这不是你鄙视我的初衷吗？

我没说我选ACD，你一定要脑补，退一步，让你脑补，我就选ACD，和你有区别吗？

你倒是硬点说说到底哪个好，好在哪撒，我选XX，你以为你舒马赫啊，我选OMEGA，我喷了

求人不如求己啊

LED backlights
See also: LED-backlit LCD television


LCD with LED matrix backlight
LED backlighting in color screens comes in two flavors: white LED backlights and RGB LED backlights.[1] White LEDs are used most often in notebooks and desktop screens, and in virtually all mobile LCD screens. A white LED is actually a blue LED with yellow phosphor to give the impression of white light. The spectral curve has big gaps in the green and red parts. RGB LEDs consist of a red, a blue, and a green LED and can be controlled to produce different temperatures of white. RGB LEDs for backlighting are found in high end color proofing displays such as HP DreamColor LP2480zx monitor or selected HP EliteBook notebooks, as well as newer consumer grade displays such as Dell's Studio series laptops which have an optional RGB LED display.
RGB LEDs can deliver an enormous color gamut to screens. When using three separate LEDs (additive color) the backlight can produce a color spectrum that closely matches the color filters in the LCD pixels themselves. In this way, the filter passband can be narrowed so that each color component lets only a very narrow band of spectrum through the LCD. This improves the efficiency of the display since little light is blocked when white is displayed. Also, the actual red, green, and blue points can be moved farther out so that the display is capable of reproducing more vivid colors. CCFL backlighting has also improved in this respect. Many current LCD models, from cheap TN-displays to color proofing S-IPS or S-PVA panels, have wide gamut CCFLs representing more than 95% of the NTSC color specification.
There are several challenges with LED backlights. Good uniformity is harder to achieve, especially as the LEDs age, with each LED possibly aging at a different rate. Also, the use of three separate light sources for red, green, and blue means that the white point of the display can move as the LEDs age at different rates. Aging also occurs with White LEDs, with changes of several 100K being recorded. White LEDs also suffer from blue shifts at higher temperatures varying from 3141K to 3222K for 10°C to 80°C respectively.[2] Power efficiency also can be a challenge. First generation implementations could use the same or more power as their CCFL counterparts, though it is possible for an LED display to be more power efficient.[citation needed] In 2010, current generation LED displays can have significant power consumption advantages. For example, the non-LED version of the 24" Benq G2420HDB[3] consumer display has a 49W consumption compared to the 24W of the LED version of the same display (G2420HDBL[4]).
The use of LED backlights in notebook computers has been growing. Sony has used LED backlights in some of its higher-end slim VAIO notebooks since 2005. Fujitsu introduced notebooks with LED backlights in 2006. In 2007, Asus, Dell, and Apple introduced LED backlights into some of their notebook models. As of 2008, Lenovo has also announced LED-backlit notebooks, and other companies like HP will also be marketing LED-backlit notebooks in the near future. In October 2008, Apple announced it will be using LED backlights for all its notebook and its new 24-inch Apple Cinema Display, and one year later it introduced a new LED iMac, meaning all of Apple's computer screens, except the 30-inch Cinema HD Display, are now LED. Almost every laptop with 16:9 display introduced since September 2009 uses LED-backlit panels.

那人整天harsh之类的词，让人摸不着头脑，你找评测也不用这么找吧

然后呢，这个技术是好，值多少钱吧

现在同档显示器贵了50美金，那在你看来这技术值多少呢？
