[問題] tn面版跟S-IPS面版

[haome (丫肥)]

真的會差很多嗎...
沒什麼概念..
但聽版上的大大都說S-IPS好....
現在又有fp2091是俗又大碗的S-IPS面版...(13900元今天問到的)
有大大可以講tn和S-IPS主要差別嗎

原文恕刪。

最近因為把學校的 LCD搬回去給家裡用，所以對 LCD板特別關心(想買新的咩)。
小弟今晚比較輕鬆之餘，為 LCD板出點微薄之力^^

轉錄自http://en.wikipedia.org/wiki/TFT_LCD中關於TN及S-IPS面板的部分。

TN+Film
The TN+Film (Twisted Nematic) display is the most common consumer display
type, due to its lower price. The pixel response time on modern TN panels
is sufficiently fast to avoid the shadow-trail artifacts that were a cause
for complaint in the past. This fast response time has been a heavily
marketed aspect of TN displays, although in most cases this number does not
reflect performance across the entire range of possible color transitions.
However this marketing strategy, combined with the relatively lower cost of
production for TN panels, has lead to the dominance of TN in the consumer
market.
譯：
因TN+Film(Twisted Nematic)顯示較低的價格，所以是最一般的消費性顯示類型。
當下TN面板的畫素反應時間快到足以避免過去被抱怨的拖曳陰影。快速的反應時間
已經是TN顯示的一大賣點，雖然大多數情況下它並未反映出跨越整個可顯示色彩尺
度的性能。然而這種銷售策略結合TN面板相對較低的製造成本，奠定了TN在消費者
市場的龍頭寶座。

The TN display suffers from limited viewing angles, especially in the
vertical direction, and some are unable to display the full 16.7 million
colors (24-bit truecolor) available from modern graphics cards. These
particular panels, with 6 bits per color channel as opposed to 8, can
approach true 24-bit color using a dither method which quickly cycles
pixels to simulate a given shade, which are noticeable to some and
discomfiting to others. Overall, color reproduction and linearity on
TN panels is poor. Shortcomings in display color gamut (often referred
to as a percentage of the NTSC color gamut) can also be attributed to
backlighting technology. It is not uncommon for displays with CCFL (Cold
Cathode Fluorescent Lamps) based lighting to range from 40% to 76% of
the NTSC color gamut, whereas displays utilizing white LED backlights
may extend past 100% of the NTSC color gamut -a difference quite
perceivable by the human eye.
譯：
TN顯示深受有限的可視角度之苦，特別是在垂直方向上，而且有些還無法顯示到當
下顯示卡可支持的1670萬色(24位元真實色彩)。這些特別的面板，每色有 6位元的
通道而非 8位元，利用顫抖法來逼近真實的24位元色彩 (顫抖法是迅速地循環畫素
來模擬特定的陰影，which are這句就真的不會翻了…)。總之，色彩重現和直線性
在TN上是糟糕的。顯示色彩範圍 (往往參照(美國)國家電視標準委員會色彩範圍的
一個百分比) 的缺點也可歸咎於背光板技術。並非罕見的以冷陰極發光燈泡為基本
光源的顯示自(美國)國家電視標準委員會色彩範圍的40%到70%都有，反之利用白色
發光二極體為背光的顯示可遠超越100%-以人類肉眼能感覺到相當地差別。

IPS
IPS (In-Plane Switching) was developed by Hitachi in 1996 to improve on the
poor viewing angles and color reproduction of TN panels. These improvements
came at a loss of response time, which was initially on the order of 50ms.
IPS panels were also extremely expensive.
譯：
IPS (In-Plane Switching)是在1996年由 Hitachi開發來改善TN面板糟糕的可視角
度還有色彩重現的。這些改進犧牲了些反應時間，一開始的反應時間是50ms。 IPS
面板過去是非常貴的。

IPS has since been superceded by S-IPS (Super-IPS), which has all the
benefits of IPS technology with the addition of improved pixel refresh
timing. Though color reproduction approaches that of CRTs, the contrast
ratio remains relatively weak. S-IPS technology only appears in larger
displays aimed at professionals, though pricing has come down to the
reach of the typical consumer.
譯：
IPS至今已被S-IPS (Super-IPS)取代，它有著 IPS科技所有的優勢更外加改善的畫
素更新時間。即使色彩重現直逼 CRT，對比比例還是相對地低。儘管價格已經低到
一般銷費大眾所及的範圍，S-IPS科技還是只出現在鎖定專業的較大型顯示中。
