应该说，POP的编辑比较善于爬文，经常性潜伏于海外论坛的最大优势，就是能得到一些消息，尽管这些消息的来历可能是错误的。不过，人家5月27号出来的文字，某些媒体没必要使用独家这类字样去吸引眼球。
好吧，关于这个EH-IPS，LGD型号为LM240WU7的面板，北美NEC的产品经理在原文中是有如下8点意见表述（原文连接： http://www.hardforum.com/showthread.php?p=1034154740&highlight=eh-ips#post1034154740）：
1. Max brightness decreases slightly to 320 cd/m^2. This is better suited for most imaging work, and will give a slightly better contrast ratio when working at very low luminance levels.
2. Color gamut remains sRGB, but is slightly better aligned with the sRGB primaries. The sRGB coverage is 96.7% (vs 93.5% on the LCD2490WUXi) in CIE xy.
3. The panel is the latest "eH-IPS A" type. This panel does not have the A-TW polarizer used on the LCD2490WUXi. The reasons for no longer using the A-TW are the same as for the LCD2690WUXi2.
4. Contrast ratio increases to 1000:1. Note that the A-TW polarizer actually decreases the contrast ratio when looking directly at the display, so this high a contrast ratio would not be possible with the A-TW.
5. The screen is not "glossy".
6. A "-SV" bundled SpectraView II version will be available in the US. The software has already been updated to support this model. It will still be possible to make your own bundle by purchasing the software or calibration kit.
7. The warranty remains 4 year in the US.
8. All other features remain the same as the LCD2490WUXi.
其中关于面板的阐述请注意第三条。第三条说明了LCD2490WUXI2是采用的EH-IPS面板，但不采用A-TW偏光板。同时也证实了LCD2690WUXI2也没有采用A-TW 偏光板。
第四条阐明不使用A-TW偏光板的好处是可以增加对比度。
所以那些为90系列二代宣传其带A-TW 偏光板的媒体们，你们可以闭嘴了。如果你是为了A-TW偏光板购买90系列产品，请买一代，二代未使用在一代上广受好评的A-TW了偏光板已经是既成事实。
同时，EH-IPS A型，那么这个EH-IPS到底和E-IPS，前一代的H-IPS有什么不同？有A型，那会不会有B型，C型？ |
