2209WA VS 2007WFP 同是IPS的王者较量 - POPPUR爱换

IPS

IPS (in-plane switching) was developed by Hitachi in 1996 to improve on the poor viewing angles and color reproduction of TN panels. Most panels also support true 8-bit per channel color. These improvements came at the cost of a slower response time, initially about 50ms. IPS panels were also extremely expensive. A partial list of LCDs that utilize IPS can be found at PcHardwareHelp.

IPS has since been superseded by S-IPS (Super-IPS, Hitachi in 1998), which has all the benefits of IPS technology with the addition of improved pixel refresh timing. Though color reproduction approaches that of CRTs, the dynamic range is lower. S-IPS technology is widely used in panel sizes of 20" and above. LG.Philips remain as one of the main manufacturers of S-IPS based panels.

Evolution of IPS LCD electrode structures and performance (from Hitachi)

AS-IPS – Advanced Super IPS, also developed by Hitachi in 2002, improves substantially on the contrast ratio of traditional S-IPS panels to the point where they are second only to some S-PVAs. AS-IPS is also a term used for NEC displays (e.g., NEC LCD20WGX2) based on S-IPS technology, in this case, developed by LG.Philips.

A-TW-IPS – Advanced True White IPS, developed by LG.Philips LCD for NEC, is a custom S-IPS panel with a TW (True White) color filter to make white look more natural and to increase color gamut. This is used in professional/photography LCDs.One such monitor to use this technology is the NEC LCD2690WUXi.

H-IPS – Released in late 2006, it improves upon its predecessor, the S-IPS panel. The H-IPS panel is used in the NEC LCD2490WUXi and LCD2690WUXi, Mitsubishi RDT261W, HP LP2475w, Planar PX2611W,[2] and Apple's newest Aluminum 24" iMac. H-IPS up close.

有个事情挺奇怪的？？？？
GZER 很多都拿到了2209 但是就是没有人提到黑屏表现漏光黑色下发红等问题吖。。。。。。。。。。。。

可能是金融风暴下LG库存清仓面板，不管好坏大批量的清仓价。就跟晚上市场上的白菜差不多意思
