16ms是否真实?(1010字) victorlynn (152955)于2004/02/05(21:25:14)..
最近打算买LCD,在到处看资料的时候,在TOMS网站的一篇评测发现下面一段话,让我对是否应该坚持选择16ms液晶产生了疑问.希望大家指点一二.
原文如下:
When we tested the first monitors of this kind, the Iiyama AS4314UTG and Hitachi CML174SXW, we were surprised to find much less afterglow on the 20-ms monitor than on the 16-ms. We have gone into this matter since then, and it turns out that the term 16 ms is exaggerated. 16 ms (max.) would be more accurate. If the manufacturers were really frank about this, they would indicate that 16-ms panels only display 262,000 colors instead of the usual 16 million. In fact, AU Optronics uses its extra fast response time to display 16 million colors in the end. With luck, the color your game needs will be one of the 262,000available to start with and, if so, the response time actually will be 16 ms.
But if the color is not in the 262,000 table, the panel will display the two closest shades alternately. Because the display is very fast, your eye will only detect one shade, the right one. But for you to see an image, the monitor has to draw two of them. (AU Optronics has confirmed this.)
And here another question crops up: how do they compare with 25-ms monitors? The tests show that the 16-ms monitors are still more responsive than the previous generation of monitors. This is mainly due to differences in the methods of evaluating response times. Some will use the time required to change from white to black and back again; others will substitute the black for a gray, and yet others will average out other results... And so, you find yourself with a problem similar to that of pitches on CRT monitors: different ways of calculating make it difficult to compare end values. If only they'd all adopt the same system.... (A guy can dream!)
大意就是友达(AUO)的16ms液晶面板真正能显示的颜色只有262,000色.其标称的1600万色实际是通过显示几帧不同的颜色来中和的.由于帧数切换远低于眼睛的反应速度,所以你看到了另外一种颜色.如果你屏幕上的所有颜色都正好在这262,000色之中,那么就可以只用一帧来完整显示,只有这时,才是真正的16ms响应速度,而当有颜色不在这262,000色之中时,由于需要显示多帧来调色,实际上的相应时间将大于16ms.因此TOMS说,所有的16ms响应时间都应该标为16ms(最快).
既然如此,在25ms和16ms的显示器之中,16ms的优势是否不如我看想象中的大呢?

16ms一般指全黑到全白这样极端的情况下的响应时间。(空) fbizhang (152967)于2004/02/05(21:51:05)..
- 全黑全白肯定正好属于262,000之中(219字) victorlynn (152971)于2004/02/05(22:03:55)..
那16ms的响应时间肯定时毫无疑问的.
但是如果是从A颜色到B颜色的转换呢,(假设A,B两种颜色至少一个不在那262,000色中)按照文章的观点,转换时间肯定会大于16ms,如果用了2帧来切换,是否可以理解成响应时间是16msX2=32ms?
由于真实颜色数是26万,可视颜色数是1600万,即使这26万种颜色是统计出来的最常出现的颜色,但是26:1600的悬殊比例,在日常使用中,肯定会经常遇到显示的颜色不在那26万色中的情况.这是否意味着16ms显示器的响应时间在很多时候实际上达不到16ms呢?
- ◎ 我记忆里面，液晶应该最大显示颜色就是26万色(33字) binhei (153037)于2004/02/06(15:00:15)..
根本不可能达到1600万色，应该所有的液晶都是通过这种方式来混合的吧。
- 16*2--不止！记得看过一篇评测，在某些情况下响应是成倍增，40ms以上（这还是乐观的看法）(空) fbizhang (152974)于2004/02/05(22:09:53)..
